Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically to a CCD dimension detection device for injection molded parts after processing. Background Technology

[0002] In the injection molding industry, injection molded parts, as fundamental components of many industrial products, directly affect the quality and performance of the final product due to their dimensional accuracy. Therefore, processed injection molded parts require rigorous dimensional inspection to ensure they meet design requirements. Traditional dimensional inspection relies primarily on manual measurement. While this method can meet inspection needs to some extent, it has several shortcomings. Manual inspection is time-consuming, labor-intensive, inefficient, and easily affected by human factors such as fatigue and visual errors, making it difficult to guarantee the accuracy and consistency of measurement results. Especially in mass production environments, manual inspection methods struggle to meet the requirements of efficient and accurate inspection. With the continuous development of optical and image processing technologies, CCD cameras have been widely used in the field of dimensional inspection. CCD cameras offer advantages such as high resolution, high sensitivity, and low noise, enabling high-definition video measurement of injection molded parts. By capturing images of the injection molded parts with a CCD camera and using image processing algorithms to analyze and process the images, efficient and accurate dimensional inspection of injection molded parts can be achieved.

[0003] The patented injection molded part size detection device, disclosed in announcement number CN217465676U, features an adjustable and reversible clamping mechanism that facilitates comprehensive video measurement of the injection molded part. This reduces errors from manual adjustment during the reversal process, resulting in highly accurate measurements. Furthermore, the device utilizes a flexibly adjustable camera measuring instrument in conjunction with the clamping mechanism, resulting in a simple structure, low operating cost, and convenient measurement capabilities.

[0004] While the aforementioned injection molded part dimensional inspection device, through its ingenious design, facilitates comprehensive video measurement of injection molded parts and significantly reduces errors from manual adjustments during flipping, thereby improving the accuracy of measurement results, it still has some shortcomings in practical applications. For example, each inspection requires operators to manually place the injection molded part inside the clamping mechanism and manually remove it after inspection. This manual loading and unloading method is not only time-consuming and labor-intensive but also increases the workload of operators. More importantly, it becomes a major bottleneck in improving inspection efficiency. In injection molded part production environments requiring large-volume, high-efficiency inspection, manual loading and unloading clearly cannot meet the demands of rapid and continuous inspection, thus limiting the improvement of overall production efficiency.

[0005] Therefore, it is necessary to invent a CCD dimension detection device for injection molded parts after processing to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a CCD dimension detection device for injection molded parts after processing, so as to solve the problems in the above-mentioned technology.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a CCD dimension detection device for injection molded parts, comprising a detection table and a conveyor table. The detection table is located at the middle of one side of the conveyor table. A loading plate is fixedly connected to the middle of the detection table. An automatic operation component is provided on the top of the loading plate. The automatic operation component includes four guide slide rods, all of which are installed on the top of the loading plate. Each of the four guide slide rods has a sliding sleeve slidably connected to its surface. A lifting plate is fixedly connected between the four sliding sleeves. A guide rail is installed on the top of the lifting plate. A sliding plate is slidably connected to the top of the guide rail. A first electric push rod is installed at one end of the lifting plate. The working end of the first electric push rod is fixedly connected to the sliding plate. An electric gripper is rotatably connected to the front of the end of the sliding plate away from the first electric push rod. A drive motor is installed on the back of the end of the sliding plate away from the first electric push rod. The output shaft of the drive motor is drivenly connected to the electric gripper. A second electric push rod is installed at the bottom of the loading plate. The top of the working end of the second electric push rod penetrates the loading plate and is fixedly connected to the bottom of the lifting plate.

[0008] By organically combining the inspection table, conveyor table, loading plate, and automatic operation components, a highly efficient and stable injection molded part size inspection device is constructed. The detailed design of the automatic operation components, including guide slide rods, sliding sleeves, lifting plates, guide slide rails, slide plates, electric push rod No. 1, electric grippers, and drive motors, ensures precise control and flexible operation of injection molded parts during the inspection process.

[0009] Preferably, one end of the top of the testing platform extends directly above the conveyor platform, and a controller is installed on the front of the extended end of the testing platform. The first electric push rod, the electric gripper, and the second electric push rod are all electrically connected to the controller.

[0010] The controller is installed at the extension end of the testing station and electrically connected to the first electric push rod, the electric gripper, and the second electric push rod, thus realizing centralized control of the entire automatic operation assembly.

[0011] Preferably, a No. 3 electric push rod is installed at the bottom of the extended end of the detection table, a CCD camera is installed at the bottom of the working end of the No. 3 electric push rod, and a belt conveyor is installed at the top of the conveyor table.

[0012] A No. 3 electric push rod and a CCD camera are installed at the bottom of the extended end of the inspection station, providing accurate imaging measurement conditions for the injection molded parts; the introduction of the belt conveyor enables continuous transportation of the injection molded parts and improves inspection efficiency.

[0013] Preferably, the CCD camera is located directly above the belt conveyor, and the No. 3 electric push rod, the CCD camera, and the belt conveyor are all electrically connected to the controller.

[0014] The detection process was automated by connecting the No. 3 electric push rod, CCD camera and belt conveyor to the controller.

[0015] Preferably, an infrared transmitter and an infrared receiver are respectively installed on both sides of the top of the conveyor platform, the infrared transmitter and the infrared receiver are matched, and the infrared receiver is electrically connected to the controller.

[0016] Infrared transmitters and receivers are installed on both sides of the top of the conveyor table. The detection process is triggered by blocking the infrared signal. This design enables automatic positioning and detection start of the injection molded parts, which helps to improve detection efficiency.

[0017] Preferably, the automatic operation component, the infrared transmitter, and the infrared receiver are located on the same straight line, and the slide plate and the electric gripper do not come into contact with the infrared receiver after extending outward.

[0018] The automatic operating component, infrared transmitter, and infrared receiver are all aligned on the same straight line, ensuring that the injection molded part can be accurately positioned in front of the automatic operating component. This design prevents the slide and electric gripper from colliding with the infrared receiver during operation, thus improving the safety and stability of the equipment.

[0019] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0020] 1. By introducing automated operation components, the automatic feeding, gripping, lifting, flipping, and unloading of injection molded parts are realized, eliminating the traditional manual feeding and unloading methods. This innovative design significantly improves inspection efficiency, especially in mass production environments, which can greatly shorten the inspection cycle and improve overall production efficiency. At the same time, automated operation also reduces the error and labor intensity of manual operation, and improves the stability and reliability of the production line.

[0021] 2. Belt conveyors are responsible for continuously and stably transporting the injection molded parts to be inspected to the inspection position, and transporting the injection molded parts out of the inspection area after the inspection is completed. The use of belt conveyors greatly improves the automation level and efficiency of the production line and reduces the need for manual intervention.

[0022] 3. The combined use of a belt conveyor with infrared transmitters and receivers enables automatic positioning and triggering of injection molded parts during the inspection process. When the injection molded part is conveyed between the infrared sensors, the inspection process is automatically triggered without manual intervention, thereby improving the automation and continuity of the entire inspection process.

It includes an inspection table 1 and a conveyor table 2. The inspection table 1 is located at the center of one side of the conveyor table 2. A loading plate 3 is fixedly connected to the center of the inspection table 1. An automatic operation component 4 is installed on the top of the loading plate 3. The automatic operation component 4 includes four guide slide rods 5, each mounted on the top of the loading plate 3. Each of the four guide slide rods 5 has a sliding sleeve 6 slidably connected to its surface. A lifting plate 7 is fixedly connected between the four sliding sleeves 6. A guide rail 8 is installed on the top of the lifting plate 7. A sliding plate 9 is connected to the lifting plate 7. A first electric push rod 10 is installed at one end of the lifting plate 7. The working end of the first electric push rod 10 is fixedly connected to the sliding plate 9. An electric gripper 11 is rotatably connected to the front of the end of the sliding plate 9 away from the first electric push rod 10. A drive motor 12 is installed on the back of the end of the sliding plate 9 away from the first electric push rod 10. The output shaft of the drive motor 12 is connected to the electric gripper 11. A second electric push rod 13 is installed at the bottom of the loading plate 3. The top of the working end of the second electric push rod 13 passes through the loading plate 3 and is fixedly connected to the bottom of the lifting plate 7.

[0032] In one aspect of this embodiment, one end of the top of the inspection table 1 extends directly above the conveyor table 2. A controller 14 is mounted on the front of the extended end of the inspection table 1. A first electric push rod 10, an electric gripper 11, and a second electric push rod 13 are all electrically connected to the controller 14. A third electric push rod 15 is mounted at the bottom of the extended end of the inspection table 1. A CCD camera 16 is mounted at the bottom of the working end of the third electric push rod 15. A belt conveyor 17 is mounted on the top of the conveyor table 2, and the CCD camera 16 is located directly above the belt conveyor 17. The electric push rod 15, CCD camera 16, and belt conveyor 17 are all electrically connected to the controller 14. Infrared transmitters 18 and infrared receivers 19 are respectively installed on both sides of the top of the conveyor table 2. The infrared transmitters 18 and infrared receivers 19 are matched. The infrared receivers 19 are electrically connected to the controller 14. The automatic operation component 4, the infrared transmitters 18, and the infrared receivers 19 are located on the same straight line. After the slide plate 9 and the electric gripper 11 extend outward, they do not come into contact with the infrared receivers 19.

[0033] The electric push rod 10, electric gripper 11, and electric push rod 13 mentioned above, along with the controller 14, electric push rod 15, CCD camera 16, belt conveyor 17, infrared transmitter 18, and infrared receiver 19, are all existing technology products, and their specific structures and functions will not be described in detail here.

[0034] Working principle of this utility model:

[0035] Refer to the instruction manual appendix Figure 1-5When using this utility model, firstly, place multiple injection molded parts to be tested one by one at equal intervals on the belt conveyor 17 of the conveyor table 2, start the belt conveyor 17, and transport the injection molded parts towards the testing table 1.

[0036] When the injection molded part moves between the infrared transmitter 18 and the infrared receiver 19, it will block the infrared signal emitted by the infrared transmitter 18. At this time, the infrared receiver 19 will not be able to receive the signal and will send a signal to the controller 14. After receiving the signal, the controller 14 will immediately control the belt conveyor 17 to stop running.

[0037] Subsequently, the controller 14 will control the third electric push rod 15 to start, and the working end of the third electric push rod 15 will move downward, driving the CCD camera 16 to move downward and take pictures to record the initial position of the injection molded part.

[0038] Next, the controller 14 will control the automatic operation component 4 to start working. First, the first electric push rod 10 is activated, pushing the slide plate 9 to move outward along the guide rail 8, so that the electric gripper 11 moves to the injection part and clamps the injection part. After clamping the injection part, the second electric push rod 13 is activated, pushing the lifting plate 7 and the slide plate 9 on it, the electric gripper 11 and the clamped injection part to move upward to a suitable position. In this way, the injection part is lifted to a certain height, which is convenient for subsequent flipping and camera measurement. The drive motor 12 is activated, driving the electric gripper 11 and the injection part on it to rotate, thereby facilitating the all-round camera measurement of the injection part.

[0039] Finally, the controller 14 will control the automatic operation component 4 to place the injection molded part back onto the belt conveyor 17, then return the automatic operation component 4 to its original position, and then start the belt conveyor 17 again. This process is repeated to send subsequent injection molded parts to the inspection station for inspection.
