Description

Technical Field

[0001] This invention relates to the field of parts quality inspection technology, specifically to a parts quality inspection device. Background Technology

[0002] In modern mechanical manufacturing, the dimensional accuracy, surface quality, and geometry of mechanical parts directly affect the overall performance and service life of the product.

[0003] Currently, existing mechanical parts inspection equipment uses industrial inspection cameras on the equipment to collect complete and effective target images of parts on conveyor belts. However, when inspecting mechanical parts, the equipment can only collect and inspect the mechanical parts located on the conveyor belt. The bottom of the mechanical parts, which contains the groove to be inspected, cannot be inspected from all angles because the mechanical parts are in contact with the conveyor belt, thus affecting the inspection efficiency. To address this, we propose a parts quality inspection device. Summary of the Invention

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0039] Please see Figures 1 to 2A parts quality inspection device includes an inspection bracket 1, a first industrial camera 2 disposed at the top of the inside of the inspection bracket 1, and a conveying mechanism 3 disposed on the inside of the inspection bracket 1. The industrial camera in this application is an existing one that can realize high-precision, non-contact automated inspection of mechanical parts.

[0040] The conveying mechanism 3 is used to convey mechanical parts. The conveying mechanism 3 includes two sets of conveying chain plates 31 and conveying sprockets 32 for driving the two sets of conveying chain plates 31. This type of conveying mechanism 3 is an existing conveying mechanism 3. It is also provided with a support frame. The support frame is provided with a drive assembly. The two conveying sprockets 32 are rotatably connected to both ends of the support frame. The drive assembly is used to drive the conveying sprockets 32. The drive assembly in this application is a motor and a gear assembly.

[0041] Two sets of conveyor chain plates 31 are fixedly connected to each other with multiple trays 4. The trays 4 in this application are round trays 4. At the same time, two protrusions are provided on the outer side of the trays 4. Then, the trays 4 are connected to two conveyor sprockets 32 through the two protrusions.

[0042] The tray 4 has a groove 41, and a support member 5 is engaged in the groove 41. A positioning rotating member 6 is provided below the detection bracket 1, and the support member 5 is transmitted to the positioning rotating member 6 through the tray 4. The positioning rotating member 6 is used to rotate the mechanical parts on the support member 5.

[0043] Please see Figures 2 to 6 The support member 5 includes a support ring 51, a rotating disk 52, a connector 53, and a snap-fit ​​member 54. The support ring 51 is snapped into the groove 41. At the same time, two positioning blocks are provided on the outer side of the support ring 51, and the support ring 51 is snapped into the groove 41 through the two positioning blocks. The rotating disk 52 is rotatably connected to the support ring 51 through a bearing. Meanwhile, the mechanical parts are placed on the rotating disk 52, and a limit ring can also be provided on the rotating disk 52. The limit ring is used to limit the mechanical parts and prevent the mechanical parts from deviating from the center of the rotating disk 52.

[0044] The connector 53 is installed at the bottom of the rotating disk 52 and is connected to the positioning rotating part 6. There are two snap-fit ​​parts 54. The two snap-fit ​​parts 54 are located at the bottom of the support ring 51. The bottom of the rotating disk 52 and the position corresponding to the two snap-fit ​​parts 54 are provided with snap-fit ​​holes 521.

[0045] The connector 53 includes a connecting rod 531 and a connecting block 532. The connecting rod 531 is fixedly installed at the bottom of the rotating disk 52, and the connecting block 532 is fixedly installed at the bottom of the connecting rod 531.

[0046] Please see Figures 4 to 6The snap-fit ​​component 54 includes a base plate 541, a snap-fit ​​rod 542, a contact rod 543, and a buffer component 544. The base plate 541 is located below the support ring 51 and the rotating disk 52. The snap-fit ​​rod 542 is fixedly installed on the base plate 541 and snaps into the snap-fit ​​hole 521. There are two buffer components 544. Both buffer components 544 are fixedly installed at the bottom of the support ring 51, and the base plate 541 is connected to the two buffer components 544. One end of the contact rod 543 is fixedly connected to the base plate 541, and a pushing inclined surface 5431 is provided on one side of the contact rod 543.

[0047] As a supplementary explanation, the buffer 544 includes a support rod 5441, a support block 5442, and a buffer spring 5443. The support rod 5441 is fixedly installed at the bottom of the support ring 51, and the base plate 541 is slidably sleeved on the outside of the support rod 5441. The support block 5442 is fixedly installed at the bottom of the support rod 5441. The buffer spring 5443 is sleeved on the outside of the support rod 5441, and the two ends of the buffer spring 5443 are fixedly connected to the base plate 541 and the support block 5442, respectively.

[0048] Please see Figure 7 The positioning rotating component 6 includes a fixed platform 61, a rotary motor 62, a rotating plate 63, an electric push rod 64, a pushing block 65, and a locking component 66. The fixed platform 61 is located below the two sets of conveyor chain plates 31. The rotary motor 62 is fixedly mounted on the fixed platform 61, and the output end of the rotary motor 62 is fixedly connected to the rotating plate 63. The electric push rod 64 is fixedly mounted on the rotating plate 63, and the output end of the electric push rod 64 is fixedly connected to the pushing block 65. The top of the pushing block 65 and the position corresponding to the connecting block 532 are provided with a connecting groove. The locking component 66 is located outside the pushing block 65 and is connected to the detection bracket 1.

[0049] The locking component 66 includes two locking rods 661, which are fixedly connected to both sides of the inner wall of the detection bracket 1. The locking rod 661 has a contact slope 6611 at one end near the pushing slope 5431. When the contact rod 543 moves to the locking rod 661, the contact slope 6611 is slidably connected to the pushing slope 5431.

[0050] Specific implementation process: When inspecting mechanical parts, the mechanical parts are placed on the rotating disk 52, and the support ring 51 on the outside of the rotating disk 52 is aligned with the groove 41 of the tray 4. The rotating disk 52 is then stably placed in the groove 41 of the tray 4. Subsequently, the mechanical parts are conveyed along the inspection bracket 1 by the two conveyor chains 31 until the contact rods 543 of the two base plates 541 below the support ring 51 contact the contact inclined surface 6611 of the locking rod 661 through the pushing inclined surface 5431. Then, as the support ring 51 holds the contact rod 6611, the mechanical parts are moved along the groove 41 of the tray 4. As the movement continues, the locking rod 661 presses down on the contact rod 543 until the support ring 51 moves directly below the detection bracket 1. Then, the two base plates 541 move vertically downward along the support rods 5441 on them. At the same time, the locking rods 542 on the base plates 541 disengage from the locking holes 521 at the bottom of the rotating disk 52. At this time, the base plates 541 no longer limit the rotating disk 52. At the same time, the locking rod 661 presses down on the contact rod 543, thereby further locking the tray 4 and the support ring 51 relative to the detection bracket 1.

[0051] Subsequently, the electric push rod 64 is operated, causing the connecting groove of the push block 65 to be fitted onto the outside of the connecting block 532, and the rotary motor 62 is operated, thereby causing the push block 65 to drive the connecting block 532 and the connecting rod 531 to rotate, which further causes the rotating disk 52 to rotate relative to the support ring 51.

[0052] As the rotating disk 52 rotates, the mechanical parts on the rotating disk 52 rotate relative to the bottom of the first industrial camera 2, so that the first industrial camera 2 can perform a vertically downward all-round inspection of the rotating disk 52.

[0053] Please see Figures 7 to 13 The inspection bracket 1 is equipped with a cooperating inspection mechanism 7, which performs all-round inspection of mechanical parts. The cooperating inspection mechanism 7 includes a lifting mechanism 71, a lifting frame 72, an inspection piece 73, a linkage 74, a push plate 75, and a second industrial camera 76. The lifting mechanism 71 is set on the inspection bracket 1, and the connecting end of the lifting mechanism 71 is connected to the lifting frame 72. The inspection piece 73 is set at the bottom of the lifting frame 72, and the linkage 74 is set on one side of the lifting frame 72 and is connected to the push plate 75.

[0054] The detection bracket 1 is provided with a sliding port, and the push plate 75 is slidably connected to the sliding port. The second industrial camera 76 is fixedly installed on the top of one end of the push plate 75. When the mechanical part moves above the rotating disk 52 along with the detection piece 73, the second industrial camera 76 moves below the mechanical part along with the push plate 75.

[0055] The detection component 73 includes an arc-shaped rotating frame 731, a U-shaped rotating frame 732, a first rotating motor 733, a second rotating motor 734, a first rotating shaft 735, a second rotating shaft 736, a circular frame 737, a fixing component 8, and a third industrial camera 9. The first rotating motor 733 and the second rotating motor 734 are both fixedly installed on both sides of the bottom of the lifting frame 72. The output end of the first rotating motor 733 is fixedly connected to the arc-shaped rotating frame 731, and the output end of the second rotating motor 734 is fixedly connected to the U-shaped rotating frame 732. One end of the first rotating shaft 735 is rotatably connected to the arc-shaped rotating frame 731, and the other end of the first rotating shaft 735 is fixedly connected to the circular frame 737. There are two second rotating shafts 736. One end of each of the two second rotating shafts 736 is rotatably connected to the U-shaped rotating frame 732, and the ends of the two second rotating shafts 736 that are close to each other are fixedly connected to the circular frame 737.

[0056] The circular frame 737 has an opening 7371, the third industrial camera 9 is located outside the opening 7371, and the third industrial camera 9 is fixedly mounted on the U-shaped rotating frame 732.

[0057] The fastener 8 is mounted on the circular frame 737 and is used to fix the mechanical parts.

[0058] The fixing component 8 includes a snap-fit ​​plate 81, a moving rod 82, a rotating ring 83, and a rotating component 84. Multiple snap-fit ​​plates 81 are provided, each L-shaped, and they snap together to fix the mechanical parts. The horizontal end of the snap-fit ​​plate 81 is slidably connected to the rotating ring 83. The moving rod 82 is fixedly installed at the bottom of the snap-fit ​​plate 81. The rotating ring 83 has an arc-shaped opening 831 corresponding to the position of the moving rod 82, and the circular frame 737 has a vertical opening 7372 corresponding to the position of the moving rod 82. The moving rod 82 slides through the arc-shaped opening 831 and the vertical opening 7372 respectively. The rotating ring 83 is rotatably connected to the inside of the circular frame 737. The rotating component 84 is installed on the circular frame 737 and is used to drive the rotating ring 83.

[0059] As a further explanation, the rotating component 84 includes a micro motor 841 and a micro gear 842. The micro motor 841 is pressed against the circular frame 737, and the output end of the micro motor 841 is fixedly connected to the micro gear 842. Multiple gear grooves are arranged around the outer side of the rotating ring 83, and the micro gear 842 is meshed with the gear grooves. Thus, the operation of the micro motor 841 further causes the micro gear 842 to rotate. When the micro gear 842 rotates, the rotating ring 83 rotates relative to the circular frame 737 through the gear grooves.

[0060] Specific implementation process: In this embodiment, when the mechanical parts rotate along with the rotating disk 52, the lifting frame 72 moves vertically up and down relative to the outside of the mechanical parts. At the same time, the third industrial camera 9 at the U-shaped frame is located on the outside of the mechanical parts, and as the mechanical parts rotate, the third industrial camera 9 performs full shooting, identification and detection of the outside of the mechanical parts.

[0061] After the outer side and top of the mechanical part are inspected, the rotating part 84 is operated, so that the rotating ring 83 rotates relative to the circular frame 737. The rotating ring 83 synchronously drives multiple arc-shaped openings 831 to rotate relative to the snap-fit ​​plate 81. Under the limiting action between the moving rod 82 and the vertical opening 7372, the snap-fit ​​plate 81 moves further along the outer side of the mechanical part until the multiple snap-fit ​​plates 81 clamp and fix the mechanical part to each other.

[0062] The lifting mechanism then moves the mechanical parts vertically upward along the rotating disk 52.

[0063] As the lifting frame 72 moves vertically upward, until it contacts the linkage 74, the push plate 75 drives the second industrial camera 76 to move downward toward the mechanical part. When the second industrial camera 76 is completely below the mechanical part, the first rotating motor 733 runs, causing the arc-shaped rotating frame 731 to rotate relative to the U-shaped rotating frame 732. The circular frame 737 rotates relative to the U-shaped frame through its two second rotating shafts 736, further driving the mechanical part to rotate and swing synchronously. At this time, the first industrial camera 2, the second industrial camera 76, and the third industrial camera 9 all capture, identify, and detect the mechanical part.

[0064] Subsequently, the second rotating motor 734 operates, causing the U-shaped rotating frame 732 to rotate relative to the arc-shaped rotating frame 731. The circular frame 737 then rotates relative to the arc-shaped rotating frame 731 via the first rotating shaft 735, further driving the mechanical parts to rotate and swing synchronously. At this time, the first industrial camera 2, the second industrial camera 76, and the third industrial camera 9 all capture images and identify the mechanical parts, thereby achieving a comprehensive and thorough inspection of the bottom and interior of the mechanical parts.

[0065] The linkage 74 includes a push cylinder 741, a linkage frame 742, a push rack 743, a rotating gear 744, a positioning component 745, a lifting sleeve 746, and a synchronizing component 747. The push cylinder 741 is fixedly installed on the lifting frame 72, and the output end of the push cylinder 741 is fixedly connected to the linkage frame 742. The other end of the linkage frame 742 is fixedly connected to the push rack 743. The push rack 743 is meshed with the rotating gear 744. The positioning component 745 is installed on the detection bracket 1 and is used to drive the lifting sleeve 746. The lifting sleeve 746 is surrounded by a lifting groove 7461. One end of the synchronizing component 747 is connected to the lifting groove 7461, and the other end of the synchronizing component 747 is connected to the push plate 75.

[0066] As a supplementary explanation, the positioning component 745 includes a damping shaft 7451, a first helical gear 7452, a second helical gear 7453, and a synchronous shaft 7454. One end of the damping shaft 7451 is fixedly connected to the rotating gear 744, and the other end of the damping shaft 7451 is fixedly connected to the first helical gear 7452. The damping shaft 7451 can only rotate when it is subjected to a certain driving force. The first helical gear 7452 and the second helical gear 7453 are meshed. The second helical gear 7453 is fixedly installed on the synchronous shaft 7454, and the bottom of the synchronous shaft 7454 is fixedly connected to the lifting sleeve 746. The synchronous shaft 7454 is rotatably connected to the detection bracket 1.

[0067] The synchronizing component 747 includes a guide shaft 7471, a synchronizing block 7472, and a push rod 7473. The detection bracket 1 is provided with a limiting groove. The synchronizing block 7472 is slidably connected to the limiting groove. One end of the guide shaft 7471 is fixedly connected to the synchronizing block 7472, and the other end of the guide shaft 7471 is slidably connected to the lifting groove 7461. One end of the push rod 7473 is rotatably connected to the synchronizing block 7472, and the other end of the push rod 7473 is rotatably connected to the push plate 75 through a hinge support.

[0068] Specific implementation process: After multiple clamping plates 81 clamp and fix the mechanical parts, the cylinder 741 is pushed to run, thereby causing the linkage frame 742 to drive the push rack 743 to move in the direction of the rotating gear 744. When the lifting frame 72 moves vertically upward, the push rack 743 contacts the rotating gear 744. As the push rack 743 continues to move, the rotating gear 744 rotates synchronously relative to the detection bracket 1 through the damping shaft 7451. When the damping shaft 7451 rotates, it drives the second helical gear 7453 to rotate through the first helical gear 7452. The second helical gear 7453 drives the lifting sleeve 746 to rotate through the synchronous shaft 7454.

[0069] As the rotating sleeve rotates, the lifting groove 7461 on it rotates synchronously relative to the guide shaft 7471. At the same time, under the limiting action of the synchronizing block 7472 and the limiting groove, the guide shaft 7471 and the synchronizing block 7472 move vertically upward along the limiting groove. When the synchronizing block 7472 moves vertically upward, it pushes the push plate 75 by pushing the support rod 7473. Under the limiting action of the sliding port, the push plate 75 drives the second industrial camera 76 to move downward toward the mechanical parts.

[0070] Once the lifting frame 72 stops moving upward, the second industrial camera 76 moves to directly below the mechanical part to inspect it.

[0071] After the mechanical parts are inspected, multiple snap-fit ​​plates 81 place the two mechanical parts back onto the rotating disk 52. Then, by pushing the cylinder 741, the push rack 743 is deviated from the vertical direction of the rotating gear 744. Thus, when the lifting frame 72 moves up again, the push plate 75 does not move towards the mechanical parts. At this time, the inspected mechanical parts can be removed from the inspection bracket 1 as the conveying mechanism 3 operates. Example 2

[0072] Please see Figures 7 to 8 Embodiment 2 further supplements the description of the lifting mechanism 71 in Embodiment 1. Specifically, the lifting mechanism 71 includes a lifting screw 711, a lifting motor 712, and a lifting block 713. The inner side of the detection bracket 1 is provided with a moving groove. The lifting screw 711 is rotatably connected to the moving groove. The lifting motor 712 is installed on the detection bracket 1 and is used to drive the lifting screw. The lifting block 713 slides through the moving groove and is threaded onto the outer side of the lifting screw 711. The lifting frame 72 is fixedly connected to the lifting block 713.

[0073] Furthermore, when the position of the lifting frame 72 relative to the detection bracket 1 is adjusted, the lifting motor 712 is operated, which further causes the lifting screw 711 to rotate relative to the inside of the moving groove. When the lifting screw 711 rotates, it provides driving force to the lifting block 713. As a result, due to the limiting effect of the moving groove, the lifting block 713 drives the lifting frame 72 to move upward or downward relative to the detection bracket 1.
