Description

Technical Field

[0002] Injection molded parts refer to various injection molded products produced by injection molding machines, including various parts, etc., which are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. After the injection molded parts are completed, it is usually necessary to perform defect detection on the surface of the injection molded parts to ensure the precise fit between the injection molded parts and the assembly. In the prior art, it is usually necessary to use an industrial camera to photograph the surface of the injection molded parts, and then upload the surface information of the injection molded parts to a computer, and compare the image information through the computer to achieve defect detection on the surface of the injection molded parts.

[0003] When the existing detection equipment is in use, it is mainly composed of a conveying component, a detection component, a clamping component and other structures to detect defects in injection molded parts.

At this time, the defects of the injection molded parts are detected by the detection component. However, in actual use, the injection molded parts are transported by the conveying component so that they pass through the detection area of ​​the detection component in sequence. After completing the single-sided detection of the injection molded parts, the injection molded parts are turned over and placed on the conveyor belt for further transportation and detection.

[0023] The implementation principle of a detection method for detecting defects of injection molded parts in this embodiment is as follows: when it is necessary to detect defects of injection molded parts, the operator clamps and fixes the injection molded parts through the clamping mechanism 4, and at this time, the injection molded parts can be detected by starting the industrial camera 312, and at this time, the electric telescopic rod 303 is started to drive the bearing plate 304 to slide on the guide rod 305, and the sliding of the bearing plate 304 can indirectly drive the gear 307 to slide on the rack 310, and because the gear 307 and the rack 310 are in a meshing state, the gear 307 can move on the rack 310 and rotate at the same time, and the rotation of the gear 307 drives the rotating rod 306 to slide in the rotating groove inside the bearing plate 304, so that the stability of the gear 307 during rotation can be increased, and the gear 307 can rotate. The rotation of the rotating rod 308 can be driven to rotate, and the rotation of the rotating rod 308 can indirectly drive the clamping mechanism 4 to rotate, and the rotation of the clamping mechanism 4 can drive the injection molded part to rotate, and the rotation of the rotating rod 308 can drive the force plate 309 to rotate. Since the distance between the rack 310 and the limit plate 311 is fixed, the force plate 309 can be in a horizontal state when it moves to the limit plate 311, and the gear 307 is in a stationary state at this time. The force plate 309 can be limited and fixed by the limit plate 311, so that the clamping mechanism 4 can maintain a horizontal state, and as the detection mechanism 3 moves and rotates, it can indirectly drive the injection molded part to move and rotate, and then the moving and rotating injection molded part can be detected by multiple industrial cameras 312, so that the detection work can be better carried out, and the working efficiency of the detection equipment is improved; When it is necessary to inspect defects of the injection molded parts, the operator pulls the four clamping plates 406 to move relative to each other. At this time, the injection molded parts are placed between the four clamping plates 406 and clamped and fixed by the clamping plates 406. At this time, the clamping mechanism 4 can be driven to move and rotate by starting the inspection mechanism 3. The movement and rotation of the clamping mechanism 4 can drive the injection molded parts to move and rotate. The injection molded parts can be inspected by the industrial camera 312. As the installation box 401 continues to move, the wedge plate 409 can be inserted into the installation box 401, so that the wedge plate 409 can contact the adjustment plate 404 and squeeze the adjustment plate 404 to move. The movement of the adjustment plate 404 can squeeze the telescopic rod 403, Spring 405, and the clamping plate 406 is driven to move by the adjustment plate 404, and the sliding plate 1 407 is driven to slide in the sliding groove by the movement of the clamping plate 406, and the clamping fixation of the injection molded part can be cancelled by the movement of the clamping plate 406, so that the injection molded part can fall onto the object-carrying plate 415, and at this time, the injection molded part on the object-carrying plate 415 can be pushed by the work of the screening mechanism 5, so that it can be pushed to the conveyor belt 1 412 and the conveyor belt 2 413 for classification, and transported to different next processes, so that it can be better used, and can cooperate with the detection mechanism 3 to clamp and fix the injection molded part, and carry out mobile rotation detection, thereby further improving the working efficiency of the detection equipment; When it is necessary to inspect the defects of the injection molded parts, the operator clamps and fixes the injection molded parts through the clamping mechanism 4, and moves and rotates the injection molded parts through the inspection mechanism 3, and performs the inspection work at the same time. When the inspected injection molded parts meet the standards, the connection plate 501 can be driven to move when the installation box 401 is reset, and the movement of the connection plate 501 drives the piston rod 502 to move, and the movement of the piston rod 502 drives the piston plate 503 to slide inside the piston box 504, and the sliding of the piston plate 503 can squeeze out the defects of the injection molded parts. The air inside the piston box 504 is compressed, and the air inside the piston box 504 can be transported to the telescopic airbag 507 through the air guide tube 506, so that the telescopic airbag 507 can be expanded and retracted, and the telescopic airbag 507 is retracted and retracted to drive the squeezing plate 510 to move, and the squeezing plate 510 can contact one side of the second bearing plate 518 through movement, and the second bearing plate 518 can be moved, and the movement of the second bearing plate 518 can drive the short push plate 517 to slide on the sliding plate 3 520, and the push plate 5 17 sliding can push the injection molded parts located on the supporting plate 415, while the short push plate 517 can only push the injection molded parts onto the conveyor belt 1 412, and the conveyor belt 1 412 is used to transport the injection molded parts to the next process that meets the standards. When the injection molded parts tested do not meet the standards, the industrial camera 312 transmits data to control the operation of the electric telescopic rod 2 515, and the electric telescopic rod 2 515 drives the fixed plate 3 514 to move through the operation of the electric telescopic rod 2 515, and the fixed plate 3 514 moves through the movement of the fixed plate 3 514 to drive the sliding plate 2 513 to slide on the guide rod 2 512, and the sliding of the sliding plate 2 513 can drive the two push plates 517 to move, so that the long push plate 517 can be located on one side of the extrusion plate 510, and then the above steps are repeated to push the injection molded parts that do not meet the standards onto the conveyor belt 2 413, and transport them to the next process that does not meet the standards through the conveyor belt 2 413, so that the defects of the injection molded parts can be better detected in cooperation with the detection mechanism 3 and the clamping mechanism 4, and the classification work can be automatically completed, thereby improving the work efficiency.
