Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and in particular to an automated testing device for injection molded parts for automobiles. Background Technology

[0002] Injection molded parts refer to all kinds of injection molded products produced by injection molding machines. After the injection molded parts of automobiles are produced and processed, they still need to be drilled. However, during the drilling process, there are often problems such as holes not being drilled through, holes being drilled crookedly, or holes being missed. Therefore, it is necessary to inspect the holes to ensure the quality of the injection molded parts leaving the factory.

[0003] Existing inspection methods generally rely on manual inspection to determine whether the holes on the product are properly opened. This requires a lot of manpower, and the eyes and brains of the staff are prone to fatigue from observing and inspecting the same product for a long time, which reduces the accuracy of manual inspection and affects the inspection results. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automated inspection device for injection molded automotive parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated inspection device for automotive injection molded parts includes a conveying mechanism. A support leg is fixedly mounted at the bottom of the conveying mechanism. A control motor is fixedly mounted on the outer side of the conveying mechanism, and the output end of the control motor is connected to a roller at one end of the conveying mechanism. A fixed frame is fixedly mounted at the middle position of the conveying mechanism. A movable block is provided on the fixed frame. A telescopic cylinder is fixedly mounted on the top of the movable block. A fixed plate is provided below the movable block, and a connecting cover is provided on the fixed plate. The telescopic end of the telescopic cylinder penetrates the movable block. A controller is fixedly mounted on the side wall of the fixed frame.

[0007] As a further embodiment of this utility model, the fixing plate is evenly provided with threaded grooves, the top of the connecting cover is fixedly installed with a threaded block, the threaded block and the threaded groove are threadedly connected, a detection rod is provided below the connecting cover, the top of the detection rod is movably installed inside the connecting cover, a pressure sensor is fixedly installed at the top inside the connecting cover, and a spring is fixedly installed between the pressure sensor and the detection rod.

[0008] As a further embodiment of this utility model, a threaded rod is movably mounted on the fixed frame, and the right side of the movable block is threadedly connected to the threaded rod. A crank handle is movably mounted on the outside of the fixed frame at a position corresponding to the threaded rod, and the crank handle is fixedly connected to one end of the threaded rod. A slider is fixedly mounted on the left side of the movable block, and a sliding groove is provided on the fixed frame at a position corresponding to the slider, so that the slider can be movably engaged in the sliding groove.

[0009] As a further embodiment of this utility model, a connecting frame is fixedly installed on the fixing plate, and a connecting groove is provided at the top center of the connecting frame, and the top of the telescopic end of the telescopic cylinder is fixedly installed in the connecting groove.

[0010] As a further embodiment of this utility model, limit blocks are fixedly installed at equal intervals on the conveyor belt of the conveying mechanism.

[0011] As a further embodiment of this utility model, an alarm is fixedly installed on the side wall of the mounting bracket, and the alarm is electrically connected to the controller.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the controller enables the control motor to drive the limit blocks on the conveying mechanism to move intermittently at equal distances. Since the limit blocks are installed at equal distances on the conveying mechanism, after each movement, the limit blocks will be directly below the fixed plate. When the controller starts the control motor, it will activate the telescopic cylinder. The telescopic end of the telescopic cylinder will drive the fixed plate to move down. When there are holes on the injection molded part that are not clear, misaligned, or missing, the detection rod will move down and press against the injection molded part. At this time, the spring will apply pressure to the pressure sensor. When the controller detects that the pressure value of the pressure sensor is not zero, it will activate the alarm to remind the staff that the injection molded part is unqualified. This achieves the effect of automatically detecting the injection molded part without manual inspection, reducing the workload of workers. Attached Figure Description

[0022] Reference Figure 1 - Figure 4 An automated inspection device for injection molded automotive parts includes a conveyor mechanism 1, which is a traditional conveyor belt type conveyor. A support leg 2 is fixedly installed at the bottom of the conveyor mechanism 1. A control motor 3 is fixedly installed on the outside of the conveyor mechanism 1. The output end of the control motor 3 is connected to a roller at one end of the conveyor mechanism 1. A fixed frame 4 is fixedly installed in the middle of the conveyor mechanism 1. A movable block 7 is provided on the fixed frame 4. A telescopic cylinder 8 is fixedly installed on the top of the movable block 7. A fixed plate 12 is provided below the movable block 7. A connecting cover 18 is provided on the fixed plate 12. The telescopic end of the telescopic cylinder 8 penetrates the movable block 7. A controller 5 is fixedly installed on the side wall of the fixed frame 4.

[0023] In this embodiment, the fixing plate 12 is evenly provided with threaded grooves 17, and a threaded block 20 is fixedly installed on the top of the connecting cover 18. The threaded block 20 is threadedly connected to the threaded groove 17. A detection rod 19 is provided below the connecting cover 18, and the top end of the detection rod 19 is movably installed inside the connecting cover 18. A pressure sensor 21 is fixedly installed on the top inside the connecting cover 18, and a spring 22 is fixedly installed between the pressure sensor 21 and the detection rod 19. An alarm 6 is fixedly installed on the side wall of the fixing frame 4, and the alarm 6 is electrically connected to the controller 5. By screwing the threaded block 20 on the top of the connecting cover 18 into the threaded groove 17, the connection can be established. Quickly fix the connecting cover 18 onto the fixing plate 12. Adjust the position of the connecting cover 18 according to the hole position on the injection molded part so that the detection rod 19 at the bottom of the connecting cover 18 can be inserted into the hole position of the injection molded part when it moves down. When there is a hole on the injection molded part that is not clear, misaligned, or missing, the detection rod 19 will move down and press against the injection molded part. The detection rod 19 will retract into the connecting cover 18. At this time, the spring 22 will apply pressure to the pressure sensor 21. The pressure sensor 21 will transmit the value to the controller 5. When the controller 5 detects that the pressure value of the pressure sensor 21 is not zero, it will activate the alarm 6 to sound an alarm to remind the staff that the injection molded part is unqualified.

[0024] In this embodiment, a threaded rod 9 is movably mounted on the fixed frame 4. The right side of the movable block 7 is threadedly connected to the threaded rod 9. A crank handle 10 is movably mounted on the outside of the fixed frame 4 corresponding to the position of the threaded rod 9. The crank handle 10 is fixedly connected to one end of the threaded rod 9. A slider 14 is fixedly mounted on the left side of the movable block 7. A groove 13 is provided on the fixed frame 4 corresponding to the position of the slider 14. The slider 14 can be movably engaged in the groove 13. By rotating the crank handle 10 to drive the threaded rod 9 to rotate, the movable block 7 can be controlled to drive the fixed plate 12 to move left and right on the top of the fixed frame 4, which facilitates the adjustment of the position of the fixed plate 12, so that the detection rod 19 at the bottom of the connecting cover 18 is aligned with the hole on the injection molded part, thereby achieving the effect of detecting injection molded parts with different hole positions.

[0025] In this embodiment, a connecting frame 15 is fixedly installed on the fixed plate 12. A connecting groove 16 is provided at the top center of the connecting frame 15. The top of the telescopic end of the telescopic cylinder 8 is fixedly installed in the connecting groove 16. The telescopic end of the telescopic cylinder 8 will drive the fixed plate 12 to move up and down.

[0026] In this embodiment, limit blocks 11 are fixedly installed at equal intervals on the conveyor belt of the conveying mechanism 1. The injection molded parts on the conveying mechanism 1 can be stuck and positioned by the limit blocks 11.

[0027] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, by screwing the threaded block 20 on the top of the connecting cover 18 into the threaded groove 17, the connecting cover 18 can be quickly fixed on the fixing plate 12. The position of the connecting cover 18 can be adjusted according to the hole position on the injection molded part, so that the detection rod 19 at the bottom of the connecting cover 18 can be inserted into the hole position of the injection molded part when it moves down. After determining the position of the connecting cover 18, the rotating handle 10 drives the threaded rod 9 to rotate, which controls the movable block 7 to drive the fixing plate 12 to move left and right on the top of the fixing frame 4, so as to facilitate the adjustment of the position of the fixing plate 12 and align the detection rod 19 at the bottom of the connecting cover 18 with the hole position on the injection molded part, thereby achieving the effect of detecting injection molded parts with different hole positions.

[0028] During testing, the injection molded part is placed between the limiting blocks 11 on the conveying mechanism 1 and positioned so that the holes in the injection molded part face upwards. Then, the controller 5 starts the control motor 3 to drive the conveying mechanism 1. The controller 5 controls the control motor 3 to move the limiting blocks 11 on the conveying mechanism 1 intermittently at equal distances. Since the limiting blocks 11 are installed at equal distances on the conveying mechanism 1, after each movement, the limiting blocks 11 will be directly below the fixed plate 12. When the controller 5 starts the control motor 3, it will start the telescopic cylinder 8. The telescopic end of the telescopic cylinder 8 will move the fixed plate 12 up and down once. Then, the controller 5 will start the control motor 3 again, and so on. When the fixing plate 12 moves down, the detection rod 19 on the top of the connecting cover 18 will be inserted into the hole of the injection molded part. When a hole on the injection molded part is not cleared, is misaligned, or is missed, the detection rod 19 will move down and press against the injection molded part. The detection rod 19 will then retract into the connecting cover 18. At this time, the spring 22 will apply pressure to the pressure sensor 21, and the pressure sensor 21 will transmit the value to the controller 5. When the controller 5 detects that the pressure value of the pressure sensor 21 is not zero, it will activate the alarm 6 to remind the staff that the injection molded part is unqualified. At the same time, it will control the device to pause, thereby achieving the effect of automatically detecting the injection molded part without manual inspection, reducing the workload of workers.
