Description

Technical Field

[0001] This utility model relates to the field of pearl cotton testing technology, specifically a device for detecting surface defects in finished pearl cotton products. Background Technology

[0002] Pearl cotton, also known as polyethylene foam, is a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles created through the physical foaming of low-density polyethylene resin. It possesses numerous excellent properties: a soft and elastic texture that allows it to conform to the surface of various items like a sponge, providing excellent cushioning and protection. Pearl cotton also boasts advantages such as being lightweight, waterproof, moisture-proof, and corrosion-resistant. Its chemical stability prevents bacterial growth and odor development, creating a safe and dry storage environment for goods. It is widely used in electronics, handicrafts, food, and many other fields.

[0003] Currently, in the production process of EPE foam, after it is made into a finished product, such as being cut and hollowed out for use as cushioning pads inside cardboard boxes, an inspection device is needed to detect surface defects. When inspecting the surface of the finished EPE foam, it is usually placed on a conveyor belt and passed through an inspection lens for surface testing. Both the top and bottom surfaces need to be inspected. This requires workers to go to the other end of the inspection device to adjust the placement of the finished EPE foam, or to reverse the conveyor belt to return the finished product to the worker's operating area for repositioning. However, this increases the inspection time and is not conducive to detecting surface defects in the finished EPE foam. Utility Model Content

The two grippers 6 are respectively fixedly mounted on the telescopic ends of the two first electric push rods 10.

[0025] Furthermore, the auxiliary mechanism also includes a first hydraulic cylinder 11 and two motors 12. The first hydraulic cylinder 11 is fixedly installed on the upper inner wall of the auxiliary workbench 4. The telescopic end of the first hydraulic cylinder 11 slides through into the interior of the storage slot 7. The first hydraulic cylinder 11 is fixedly connected to the top plate 5. The two motors 12 are respectively fixedly installed on the left and right surfaces of the two first mounting plates 8. The output ends of the two motors 12 rotate through to the two connecting rods 9. The two motors 12 are respectively fixedly connected to the two connecting rods 9.

[0026] Furthermore, through the coordinated operation of components such as the first hydraulic cylinder 11, the second hydraulic cylinder 14, the first electric push rod 10, the second electric push rod 18, and the motor 12, the fully automated operation of the EPE foam finished product from grasping, flipping to transferring is realized, reducing manual intervention, reducing the labor intensity of workers, and improving the inspection efficiency of the EPE foam finished product.

[0027] Furthermore, support plates 13 are fixedly installed at both ends of the auxiliary workbench 4. The two support plates 13 are located below the two first mounting plates 8 respectively. The lower surfaces of the two support plates 13 are fixedly installed with second hydraulic cylinders 14. The telescopic ends of the two second hydraulic cylinders 14 slide through to the upper surfaces of the two support plates 13 respectively. The telescopic ends of the two second hydraulic cylinders 14 are fixedly connected to the two first mounting plates 8 respectively.

[0028] Furthermore, rectangular grooves 15 are provided at both the left and right ends of the top plate 5, and both the upper and lower ends of the two rectangular grooves 15 are open.

[0029] Furthermore, a triangular inclined plate 16 is fixedly connected to the upper surface of the top plate 5. The triangular inclined plate 16 is located at the front end of the two rectangular grooves 15, and the inclined direction of the triangular inclined plate 16 is forward and upward.

[0030] Furthermore, a second mounting plate 17 is fixedly installed on the rear end of the upper surface of the auxiliary workbench 4, and a second electric push rod 18 is fixedly installed on the rear surface of the second mounting plate 17. The front end of the second electric push rod 18 extends through to the front end of the second mounting plate 17, and a push plate 19 is fixedly installed on the telescopic end of the second electric push rod 18.

[0031] Furthermore, when using this device to inspect the surface defects of finished pearl cotton products, such as those used as cushioning pads, the finished pearl cotton product is placed on the influence measuring instrument body 2. Then, the inspection lens on the mounting frame 3 inspects the surface of the pearl cotton product. After inspection, the finished pearl cotton product is moved to the top plate 5 on the auxiliary worktable 4. At this time, the first hydraulic cylinder 11 is activated, its telescopic end pushing the top plate 5 upward from the receiving groove 7 to lift the pearl cotton product. Then, the second hydraulic cylinder 14 is activated, its telescopic end extending upward to push the first mounting plate 8 upward at both ends of the auxiliary worktable 4, moving the gripper 6 to a suitable gripping height. The first electric push rod 10 is activated, its telescopic end extending to move the gripper 6 closer to the pearl cotton. When the gripper 6 reaches the appropriate position, the electric telescopic rod on the gripper 6 drives the gripper 6 to close, gripping the finished pearl cotton product. At this time, the motor 12 can be started. The output end of the motor 12 drives the connecting rod 9 to rotate forward or backward. The rotation direction of the motor 12 must be opposite to the previous rotation each time. Since the connecting rod 9 is connected to the first electric push rod 10 and the gripper 6, the gripper 6 that grips the pearl cotton will flip, thereby flipping the finished pearl cotton product. After the flipping is completed, the second electric push rod 18 is started. Its telescopic end pushes the push plate 19 forward, pushing the finished pearl cotton product located on the top plate 5 towards the image measuring instrument body 2. The conveyor belt on the image measuring instrument body 2 rotates in the opposite direction, driving the finished pearl cotton product to the bottom of the image measuring instrument body 2 for defect detection on the lower surface.
