Description

Technical Field

[0001] This utility model relates to the field of injection molded part aperture detection technology, specifically to an online injection molded part aperture detection device. Background Technology

[0002] Injection molded part aperture inspection is an important tool to ensure the quality of injection molded parts. It can usually achieve real-time monitoring of aperture size to ensure that the product meets the design requirements. It can monitor the space of injection molded parts on the production line, promptly detect and remove unqualified products, thereby ensuring the stability and consistency of product quality.

[0003] According to the Chinese patent publication CN222027646U, "An Online Detection Device for the Hole Diameter of Injection Molded Parts," the device mainly describes a process where, when detecting the hole diameter, pressing a U-shaped handle causes a suction cup to adhere to the surface of the injection molded part near the hole. Pressing a push rod then releases the locking mechanism between the U-shaped handle and the support column, allowing adjustment of the distance between the U-shaped handle and the injection molded part. This facilitates the detection of the hole's inner diameter. The device can be operated with one hand and placed at any hole on the injection molded part, offering high convenience and eliminating the need for frequent movement of the injection molded part to adjust its position, making it easy and quick to use.

[0004] Online inspection of injection molded part hole diameter requires an automatic feeding mechanism to transport the injection molded part to the inspection station in a specific direction. The injection molded part is then precisely positioned and clamped by a fixture. A high-precision sensor is used to detect the hole diameter of the injection molded part. The data collected by the sensor is then processed and compared by a processing unit to determine whether the hole diameter of the injection molded part is qualified. This online inspection method is usually batch-based. During the inspection process, the position of the detection probe relative to the hole diameter of the injection molded part needs to be constantly adjusted to determine the center position of the positioning hole of the injection molded part, which affects the efficiency of online inspection.

[0005] Therefore, an online detection device for injection molded part aperture is proposed to solve the problem that the position of the detection probe and the injection molded part aperture needs to be constantly adjusted during the detection process to determine the center position of the positioning hole of the injection molded part, which affects the efficiency of online detection. Utility Model Content

[0006] The technical problem this invention aims to solve is that the position of the detection probe and the hole diameter of the injection molded part needs to be constantly adjusted during the detection process to determine the center position of the positioning hole of the injection molded part, which affects the efficiency of online detection.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3The device shown is an online detection device for the bore diameter of injection molded parts, including a support plate 1, a first motor, a rotating roller 2, and a conveyor belt 3. The first motor is a stepper motor, which drives the rotating roller 2 and the conveyor belt 3 to rotate, thereby causing the injection molded part placed on the conveyor belt 3 to move. Two support plates 1 are provided, and a connecting frame 4 is fixedly connected to the upper end of the two support plates 1. A second motor is fixedly connected to one side of the connecting frame 4. The second motor drives the first screw 5 to rotate, thereby causing the moving block 6 and the fixed frame 7 to move on the upper side of the connecting frame 4. The output end of the second motor is fixedly connected to the first screw 5, and the moving block 6 is threadedly connected to the first screw 5. The bottom end of the moving block 6 is fixedly connected to the fixed frame 7. A third motor is fixedly connected. This third motor is a forward and reverse motor with a rotation angle of 180°. The third motor drives the turntable to rotate, which in turn causes the electric push rod 8 and the fixed plate 9 to rotate. The output end of the third motor is fixedly connected to the turntable, and the bottom end of the turntable is fixedly connected to the electric push rod 8. The bottom end of the electric push rod 8 is fixedly connected to the fixed plate 9. A bracket is movably inserted into one side of the fixed plate 9, and a horizontal plate 10 is fixedly connected to the upper end of the bracket. A fourth motor is fixedly connected to one side of the upper end of the horizontal plate 10. The fourth motor drives the second screw 11 to rotate, which causes the moving plate 12 and the laser aperture detector 13 to move downward. In conjunction with the electric push rod 8, they can penetrate into the drilled hole of the injection molded part. The output end of the fourth motor is fixedly connected to... A second screw 11 is connected, and a movable plate 12 is threaded onto the second screw 11. A laser aperture detector 13 is fixedly connected to the center of the bottom end of the movable plate 12. The laser aperture detector 13 is a high-precision measurement device based on the laser principle, usually based on the laser triangulation method or the laser interference principle. It measures the size of the object by emitting a beam of light onto the object being measured, receiving the reflected light signal, and calculating the changes in the light signal. The laser aperture detector 13 executes its own program. A positioning groove 14 is opened on one side of the movable plate 12, and a connecting plate 15 contacts the positioning groove 14. An adapting rod 16 is fixedly connected to the bottom end of the connecting plate 15. The positioning groove 14... A positioning rod 17 is inserted into the side, and the positioning rod 17 is inserted into the connecting plate 15. Hydraulic push rods 18 are fixedly connected to both sides of the connecting frame 4. When the hydraulic push rod 18 extends, it can drive the two clamping plates 19 to move relative to each other. At the same time, it can provide a limit for the injection molded part in conjunction with the limiting plate 21. The output end of the hydraulic push rod 18 is fixedly connected to the clamping plate 19. A first groove is opened in the clamping plate 19. A fifth motor is fixedly connected to one side of the clamping plate 19 located in the first groove. A bidirectional screw 20 is fixedly connected to the output end of the fifth motor. The two opposite sides of the bidirectional screw 20 are threadedly connected to the limiting plate 21. The fifth motor drives the bidirectional screw 20 to rotate, which can make the two opposite limiting plates 21 move relative to each other.

[0019] Among them, both sides of the bottom end of the clamping plate 19 are rotatably embedded with sliding balls 22, which are in contact with the conveyor belt 3. By setting the sliding balls 22, the friction between the clamping plate 19 and the conveyor belt 3 can be reduced.

[0020] One side of the conveyor belt 3 is in contact with a pad 23, which is fixedly connected to the support plate 1. Both sides of the upper end of the support plate 1 are provided with arc corners. By setting the pad 23, support is provided for the conveyor belt 3, so that the punching position of the injection molded part remains stable when it is being inspected.

[0021] A sixth motor is fixedly connected to one side of the support plate 1. A rotating rod 24 is fixedly connected to the output end of the sixth motor. Connecting rods 25 are evenly fixedly connected to the rotating rod 24. A baffle 26 is fixedly connected to the connecting rod 25. The sixth motor drives the rotating rod 24, the connecting rod 25 and the baffle 26 to rotate, which can cooperate with the conveyor belt 3 to convey the injection molded part, so that one side of the injection molded part contacts the baffle 26, thereby adjusting the angle of the injection molded part on the conveyor belt 3.

[0022] The fixed plate 9 has a hidden groove 27 on its bottom side, which corresponds to the laser aperture detector 13. By setting the hidden groove 27, the detection end of the laser aperture detector 13 can be hidden.

[0023] Working principle: The injection molded part is placed on the conveyor belt 3, and the sixth motor drives the rotating rod 24, connecting rod 25 and baffle 26 to rotate. At this time, one side of the injection molded part contacts the baffle 26, so that one side of the injection molded part is flush with the conveyor belt 3. Then the injection molded part on the conveyor belt 3 continues to move and gradually enters between the two clamping plates 19. It is limited by the limiting plate 21, which can improve the limiting of the injection molded part. Then the second motor drives the first screw 5 to rotate, and causes the moving block 6 and the fixed plate 9 to move within the connecting frame 4. Then the appropriate hole diameter adaptation rod 16 is selected, and the positioning rod 17 provides the limit. At this time, the electric push rod 8 extends, causing the adaptation rod 16 to enter the hole on the injection molded part. Then the electric push rod 8 retracts and starts the third motor in the fixed frame 7 to rotate, and causes the fixed plate 9 to rotate. At this time, the laser hole diameter detector 13 corresponds to the hole on the injection molded part, thereby performing monitoring and improving the detection efficiency.
