Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and more specifically, to a 3D testing device. Background Technology

[0002] With the rapid development of industries such as precision manufacturing, electronic components, and optical devices, the market has increasingly stringent requirements for the inspection of product appearance and dimensional accuracy. 3D inspection equipment is widely used in production lines because it can accurately acquire three-dimensional data of products and identify minute defects. In order to realize the automated closed loop of inspection and sorting, existing 3D inspection equipment usually integrates a feeding platform, an inspection module, and a sorting module. The platform and sorting module are linked by a drive module to complete the entire process of product inspection, defect marking, and sorting of non-conforming products.

[0003] Among them, the sorting of defective products is particularly critical. Defective products already have defects such as surface scratches, cracks, and dimensional deviations. Currently, existing 3D inspection equipment is prone to positioning deviations, clamping damage, or secondary collisions during the sorting of defective products, which can easily lead to the expansion of defects or even complete scrapping, significantly increasing production costs. At the same time, after the product is placed in the feeding trough for inspection, the trough wall will block the movement space of the gripper. Especially in deep and narrow trough scenarios, the gripper is prone to interference with the trough wall, making it impossible to accurately approach the product to achieve bottom support or side clamping, resulting in problems such as clamping deviation and empty clamping, which seriously affects sorting efficiency.

[0004] In view of this, we propose a 3D inspection device. Summary of the Invention

The hydraulic rod and the first piston rod are both located on the side of the cylinder and the first cavity near the support frame.

The elastic connecting plate is located below the first rack, and the bottom of the elastic connecting plate is fixedly connected to the top of the gripper.

The side of the driven gear away from the transmission gear meshes with the second rack. The second rack, driven gear, and transmission gear are all located below the feeding platform.

[0016] As an optional solution to the technical solution of this application, the lifting assembly includes several first slids formed at the bottom of the feeding platform.

[0020] As an optional solution to the technical solution of this application, the size of the abutment block is smaller than the size of the baffle. The two abutment blocks extend through the inner wall of the second slide groove to both sides of the lifting plate. The third vent groove is located below the air inlet. The second slide groove communicates with the interior of the second cavity through the third vent groove. The air inlet is connected to the second slide groove. The side of the baffle away from the abutment block is elastically connected to the inner wall of the second slide groove through the second elastic element. The baffle has a small hole.

[0021] By adopting the above technical solution, the pressure relief component can be set up to avoid the negative pressure of the lifting plate from conflicting with the clamps.

[0022] Beneficial effects: One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0023] 1. During the process of the driving gripper descending to prepare for gripping, the second rack is driven upward by the transmission of the first rack, the driving gear, the synchronous belt, the transmission gear and the driven gear, which pushes the lifting plate to push the product out of the feeding trough. The product is completely freed from the trough constraint, and the gripper can approach and achieve bottom support or side gripping without obstruction. This avoids the problems of insufficient gripping space in the trough, interference between the gripper and the trough wall, and inability to accurately align, making it easier to grip and sort the product.

[0024] 2. During the upward movement of the lifting plate, the elastic compression pump body is stretched simultaneously, thereby generating negative pressure inside the second cavity. Under the action of negative pressure, the stepped piston rod is driven downward. Negative pressure is generated in the space above the stepped piston rod where the negative pressure port is located. Since the product blocks the negative pressure port, the negative pressure inside the negative pressure port can attract the bottom of the product to the top of the lifting plate. This prevents the product from sliding, shifting, or even falling and causing wear and tear due to vibration, tilting, or smooth contact surfaces during the lifting process. It also helps to ensure that the product's position does not shift before it is picked up and clamped, facilitating product sorting.

[0025] 3. During the clamping process, a negative pressure is generated on the side of the first cavity near the first piston rod. This negative pressure is generated at the air intake through the first and second air grooves. When the gripper approaches the product, the top of the gripper moves towards the bottom of the product under the action of the negative pressure and the inclined surface. This causes the part of the bottom of the product that exceeds the lifting plate to abut against the top of the gripper, thus achieving the function of supporting the bottom and improving the stability of subsequent movement.

[0026] 4. As the grippers approach the product, the inclined surfaces on the grippers simultaneously abut against the contact blocks on the side of the lifting plate. This causes the contact blocks to move the baffle closer to the second elastic element, compressing the second elastic element and aligning the small holes on the baffle with the air inlet and the third ventilation groove. At this time, the second cavity will draw in air from the outside through the second elastic element and the air inlet under the action of negative pressure, releasing the negative pressure and thus releasing the lifting plate from adhering to the bottom of the product. This achieves a seamless switch from lifting and adhering to gripper negative pressure support, avoiding premature release of adhering which could cause the product to slide and shift, and also avoiding premature release of adhering which could cause the grippers and the lifting plate to pull the product and amplify defects. The product maintains a stable posture throughout the process, protecting the original state of the defective part.

[0027] 5. At the same time, the inclined plane guides the smooth movement of the contact block and the gripper moves smoothly towards the bottom of the product, which will not cause rigid impact on the lifting plate or the product, and avoid product bumps and defects caused by mechanical collisions.

[0028] 6. After the side wall of the gripper comes into contact with the product, the continued movement of the first piston rod will cause the elastic connecting plate to bend, generating elastic force on the gripper. This elastic force increases the flexible clamping force on the product, providing sufficient clamping force to fix the product while also buffering the impact force through its own deformation, avoiding local pressure concentration, which could lead to clamping damage and the expansion of defects in the product.

[0029] 7. After being lifted, the product is removed from the discharge chute. The grippers support the bottom in time, forming a support from the bottom. Combined with subsequent negative pressure adsorption and elastic clamping, the product is double-fixed by lifting from the bottom and clamping from the side, effectively preventing the product from sliding, tilting or even falling during the sorting process, and preventing defective products from expanding due to collision and friction.

[0048] The top of the feeding platform 106 is evenly provided with several feeding slots 18. The detection camera 105 is located between the second linear drive module 104 and the feeding platform 106. The drive component 11 is located on the side of the second linear drive module 104 away from the detection camera 105. The support frame 108 is located on the side of the second linear drive module 104 close to the drive component 11.

[0049] Reference Figures 2 to 9 This application provides a 3D inspection device. The drive assembly 11 includes a connecting plate 111 disposed on the second linear drive module 104. A hydraulic cylinder 112 is disposed on the connecting plate 111. A hydraulic rod 118 is slidably connected inside the hydraulic cylinder 112. A cylinder 114 is disposed at the bottom of the hydraulic rod 118. A telescopic rod 115 is disposed on the side of the cylinder 114. A first cavity 116 is disposed below the cylinder 114. A first piston rod 117 is disposed on the side of the first cavity 116. A first rack 113 is fixedly connected to the side of the cylinder 114 away from the hydraulic rod 118.

[0050] The top of the first rack 113 extends through the bottom of the connecting plate 111 to the top of the connecting plate 111. The bottom of the hydraulic rod 118 extends through the top of the connecting plate 111 to the bottom of the connecting plate 111. The hydraulic rod 118 and the first piston rod 117 are both located on the side of the cylinder 114 and the first cavity 116 near the support frame 108. An elastic connecting plate 12 is fixedly connected to the side of the first cavity 116 and the side of the first piston rod 117 that are far apart from each other. The elastic connecting plate 12 is located below the first rack 113. The bottom of the elastic connecting plate 12 is fixedly connected to the top of the gripper 13.

It is currently L-shaped, with the inclined surface 17 located on the side where the two grippers 13 are close to each other, the air intake 16 located on the top of the grippers 13, the first venting groove 14 extending through the inner wall of the elastic connecting plate 12 to the side of the first cavity 116 near the first piston rod 117, and the second venting groove 15 extending through the inner walls of the elastic connecting plate 12 and the first piston rod 117 to the side of the first cavity 116 near the first piston rod 117.

[0051] Both the first linear drive module 103 and the second linear drive module 104 are preferably linear drive structures consisting of a motor, a lead screw, and a lead sleeve. The detection camera 105 and the connecting plate 111 are fixedly connected to both sides of the lead sleeve in the second linear drive module 104, the bottom of the feeding platform 106 is fixedly connected to the top of the lead sleeve in the first linear drive module 103, the gripper 13 is located above the feeding platform 106, and the distance between the two first linear drive modules 103 is greater than the width of the feeding trough 18.

[0052] After the side wall of the gripper 13 comes into contact with the product, the first piston rod 117 continues to move, which will cause the elastic connecting plate 12 to bend and generate elastic force on the gripper 13. The elastic force increases the flexible clamping force on the product, which can not only provide sufficient clamping force to fix the product, but also buffer the impact force through its own deformation, avoiding local pressure concentration, which could cause clamping damage and expand the defects of the defective product.

[0053] Reference Figures 2 to 10 This application provides a 3D detection device. The transmission component 20 includes a plurality of driving gears 201 rotatably connected to a support frame 108. A pulley 202 is fixedly connected to the side of the driving gear 201. A synchronous belt 203 is provided on the pulley 202. A plurality of transmission gears 204 and driven gears 205 are rotatably connected to the support frame 108. A plurality of second racks 206 are slidably connected inside the support frame 108.

[0054] The drive gear 204 meshes with the driven gear 205. A pulley 202 is fixedly connected to the side of the drive gear 204.

[0056] Reference Figures 6 to 10This application provides a 3D inspection device. The lifting assembly 21 includes a plurality of first slide grooves 211 formed at the bottom of the feeding platform 106. A slide rod 212 is slidably connected inside the first slide groove 211. A lifting plate 213 is fixedly connected to the top of the slide rod 212. An elastic compression pump body 214 is provided inside the feeding trough 18. A second cavity 215 is formed inside the lifting plate 213. A stepped piston rod 216 is slidably connected inside the second cavity 215. A first elastic element 217 is provided inside the second cavity 215. A negative pressure port 218 is provided at the top of the lifting plate 213.

[0057] The top of the slide rod 212 extends through the inner wall of the first slide groove 211 to the inside of the discharge trough 18.

[0058] Several second racks 206 are aligned with several first grooves 211 respectively. The top of the second rack 206 is in contact with the bottom of the slide bar 212. During the upward movement of the lifting plate 213, the elastic compression pump body 214 is stretched simultaneously, thereby generating negative pressure inside the second cavity 215. Under the action of negative pressure, the stepped piston rod 216 is driven downward. Negative pressure is generated in the space above the stepped piston rod 216 at the negative pressure port 218. Since the product blocks the negative pressure port 218, the negative pressure inside the negative pressure port 218 can attract the bottom of the product to the top of the lifting plate 213. This prevents the product from sliding, shifting, or even falling due to vibration, tilting, or smooth contact surface during the lifting process, which could cause it to bump and wear. At the same time, it also helps to ensure that the product's position does not shift before it is picked up and clamped, which facilitates the sorting of the product.

[0059] Reference Figure 6 , Figure 7 and Figure 10 This application provides a 3D detection device. The pressure relief component 22 includes an air inlet 221 opened on the top of the lifting plate 213. The lifting plate 213 has a second sliding groove 222 on both sides.

The side of the baffle 223 is fixedly connected with an abutment block 224. The lifting plate 213 has a third ventilation groove 225 inside.

[0060] The size of the abutment block 224 is smaller than that of the baffle 223. The two abutment blocks 224 extend through the inner wall of the second slide groove 222 to both sides of the lifting plate 213. The third vent groove 225 is located below the air inlet 221. The second slide groove 222 communicates with the interior of the second cavity 215 through the third vent groove 225. The air inlet 221 communicates with the second slide groove 222. The side of the baffle 223 away from the abutment block 224 is elastically connected to the inner wall of the second slide groove 222 through the second elastic member 226. The baffle 223 has a small hole.

[0061] This application provides a 3D inspection device, the working principle and usage process of which are as follows:

[0062] First, the first linear drive module 103 drives the feeding platform 106 to move out from under the support frame 108. Then, the products to be inspected are placed into each feeding slot 18. Then, according to the preset program, the first linear drive module 103 drives the feeding platform 106 to move intermittently towards the support frame 108 at a specific distance, ensuring that the detection range under the detection camera 105 is aligned with the feeding slot 18 every time the feeding platform 106 stops. Then, the second linear drive module 104 drives the detection camera 105 to move laterally when the feeding platform 106 stops, performing 3D inspection on the products in this feeding slot 18, displaying the inspection results on the display screen 102, and marking defective products.

[0063] After inspection, the system controls the sliding of the unloading platform 106 and the connecting plate 111 via the first linear drive module 103 and the second linear drive module 104, moving the defective product to the space below the two grippers 13. At this time, the second rack 206 aligns with the slide bar 212, and the first rack 113 meshes with the corresponding drive gear 201. The hydraulic cylinder 112 then moves the hydraulic rod 118 downwards, causing the first rack 113 to move downwards and the grippers 13 to move closer to the unloading platform 106, thereby causing the drive gear 201 to rotate. The rotation of the drive gear 201, through the synchronous belt 203, drives the transmission gear 204 to rotate. The rotation of the transmission gear 204, in turn, drives the driven gear 205, which meshes with it, to rotate. The rotation of wheel 205 will drive the second rack 206, which meshes with it, to move upward. The upward movement of the second rack 206 will press the slide bar 212 upward, which will drive the lifting plate 213 to push the product out of the discharge trough 18 and stretch the elastic compression pump body 214, causing the volume of the elastic compression pump body 214 to expand. This will generate negative pressure inside the second cavity 215. Under the action of negative pressure, the stepped piston rod 216 will move downward, compressing the first elastic element 217 and generating negative pressure in the space above the stepped piston rod 216 at the negative pressure port 218. Since the product blocks the negative pressure port 218, the negative pressure inside the negative pressure port 218 can attract the bottom of the product to the top of the lifting plate 213, preventing the product from sliding during the process of the lifting plate 213 pushing the product out, which would make it impossible to clamp it later.

[0064] When the gripper 13 descends to the position where it is in contact with the unloading platform 106, the lifting plate 213 pushes the product out of the unloading groove 18, and the lifting plate 213 also moves out of the unloading groove 18. At this time, the end of the gripper 13 near the inclined surface 17 is below the product, and the lifting plate 213 is located between the two grippers 13. At this time, the telescopic rod 115 is moved towards the cylinder 114 by the cylinder 114, thereby driving the first piston rod 117 to move towards the first cavity 116. A negative pressure is generated on the side of the first cavity 116 near the first piston rod 117, thereby generating a negative pressure at the suction hole 16 through the first vent groove 14 and the second vent groove 15. When the gripper 13 approaches the product, it can be lifted by the negative pressure and the action of the inclined surface 17. The top moves towards the bottom of the product, so that the part of the bottom of the product that exceeds the lifting plate 213 abuts against the top of the gripper 13, thus achieving the function of supporting the bottom. During the process of the inclined surface 17 on the gripper 13 abutting against the side of the lifting plate 213, the contact block 224 will be squeezed first, causing the contact block 224 to drive the baffle 223 to move towards the second elastic member 226, compressing the second elastic member 226 and driving the small hole on the baffle 223 to align with the air inlet 221 and the third ventilation groove 225. At this time, the second cavity 215 will draw in air from the outside through the second elastic member 226 and the air inlet 221 under the action of negative pressure, releasing the negative pressure, thereby releasing the suction of the lifting plate 213 to the bottom of the product. At this time, the side of the two grippers 13 that is close to each other abuts against the side of the product.

[0065] Finally, the hydraulic cylinder 112 drives the gripper 13 upward, and the first piston rod 117 continues to move towards the first cavity 116, which will cause the elastic connecting plate 12 to bend and generate elastic force on the gripper 13. The elastic force increases the flexible clamping force on the product, and the negative pressure at the suction hole 16 will make the product more stable during the movement. Then, the second linear drive module 104 drives it to move to the right above the collection box 107, and the product is placed in it. The above steps are repeated to sort the defective products.
