Description

Technical Field

[0001] This invention relates to the technical field of automotive parts inspection, specifically a method for inspecting automotive plastic parts. Background Technology

[0002] Automotive plastic parts, which are product accessories made of plastic, are one of the main components of a car. They are frequently used in the body shell, interior, lighting, transmission system, emission system, and electrical system. Today, with the development of the automotive industry, the uses of plastics are becoming increasingly widespread, and automotive plastic parts are becoming more and more common. To ensure driver safety, automotive plastic parts must undergo rigorous testing before leaving the factory.

[0003] Currently, the inspection of automotive plastic parts typically uses optical methods to detect defects and flaws. Generally, the plastic parts are placed on a conveyor belt and transported to the bottom of the inspection device for inspection.

[0039] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0040] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0041] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0042] Please see Figures 1-9 In this embodiment of the invention, a method for testing automotive plastic parts includes the following steps:

[0043] Step 1: Place the plastic part into the area to be inspected;

[0044] Step 2: Use testing equipment to inspect the plastic parts;

[0045] Step 3: The detection device transmits the collected information to the computer;

[0046] Step 4: The computer compares and analyzes the transmitted information with images of qualified plastic parts to determine whether they are qualified.

[0047] The detection device includes a base 1 and a rotating component disposed on the base 1;

[0048] It also includes a clamping mechanism installed on the base 1. The clamping mechanism includes a support shaft 11 and clamping units symmetrically arranged on the support shaft 11. The clamping member is connected to the rotating member. The clamping member can perform clamping or opening work on the plastic part. When performing clamping work, the rotating member controls the clamping member to rotate.

[0049] An intermittent drive component is installed on the base 1 and connects the clamping component, the rotating component, and the support shaft 11. After the plastic part completes unidirectional rotation, the support shaft 11 is controlled to rotate, thereby changing the clamping position of the clamping component on the plastic part.

[0050] In detail, the present invention employs the automotive plastic parts inspection method described herein. During use, the plastic part is first placed in the area to be inspected. The gap drive is activated, controlling the clamping component to clamp the plastic part. Then, the rotating component is driven, causing the clamping component to rotate, thus enabling the inspection of the plastic part. Subsequently, the clamping component stops rotating and opens and resets the plastic part. Under the action of the gap drive, the support shaft 11 rotates, causing the clamping component to rotate synchronously. When the clamping component clamps and rotates the plastic part again, the clamping position changes, achieving comprehensive inspection of the plastic part and improving inspection accuracy.

[0051] Please see Figure 2 , Figure 3 The base 1 is symmetrically provided with guide rails 2, and a first receiving frame 3 and a second receiving frame 4 are slidably provided on the guide rails 2 respectively. A conveying component 6 is fixedly connected to the first receiving frame 3, and a visual detector 5 is fixedly connected to the second receiving frame 4. The first receiving frame 3 and the second receiving frame 4 are fixedly provided.

[0052] The aforementioned conveyor 6 transports the plastic part to the position to be inspected. After the clamping component clamps the plastic part, the first receiving frame 3 and the second receiving frame 4 move synchronously. At this time, the vision detector 5 is located above the area to be inspected and performs inspection on the plastic part. Before the clamping component opens the plastic part, the conveyor 6 moves again above the plastic part to receive it, so as to prevent the plastic part from falling and affecting subsequent inspection work.

[0053] Please see Figure 5 , Figure 6 The clamping unit includes a support plate 12 fixedly installed on the support shaft 11. A through groove is symmetrically formed on the support plate 12. A slider 13 is slidably arranged in the through groove. A telescopic member is connected to the slider 13.

[0054] It also includes a sleeve 18 slidably disposed on the support shaft 11, the sleeve 18 being disposed axially along the support shaft 11, a movable plate 19 being rotatably mounted on the sleeve 18, the movable plate 19 being slidably disposed on the base 1 via a guide rod 20, a limiting groove 1901 being formed on the movable plate 19, and a hinge rod 17 being rotatably mounted on the sleeve 18, the end of the hinge rod 17 away from the sleeve 18 being rotatably connected to the slider 13.

[0055] In detail, when the start-up gap drive is working, the movable plate 19 reciprocates under the transmission action of the pusher. When the movable plate 19 moves downward, it drives the sleeve 18 to move synchronously. Under the action of the hinge rod 17, the slider 13 slides in the through groove. When the slider 13 moves, it drives the telescopic part on it to slide synchronously, so as to achieve the clamping work of the plastic part.

[0056] Please see Figure 6 The telescopic component includes a plug-in tube 15, which is rotatably mounted on the support plate 12, and a first bevel gear 16 is fixedly connected to the end of the plug-in tube 15.

[0057] It also includes a movable shaft 14 rotatably mounted on the slider 13, one end of the movable shaft 14 being slidably disposed inside the insertion cylinder 15, and the other end being fixedly connected to a clamping plate 1401.

[0058] When the slider 13 moves, it drives the movable shaft 14 to move synchronously. At least one strip groove 1501 is formed inside the insertion cylinder 15. A strip slider 1402 is formed on the movable shaft 14 that slides with the strip groove 1501. When the movable shaft 14 moves, it drives the strip slider 1402 to move synchronously. Under the restriction of the strip groove 1501 and the strip slider 1402, the movable shaft 14 and the insertion cylinder 15 are slidably connected. This does not affect the synchronous rotation of the movable shaft 14 when the insertion cylinder 15 rotates. The movable shaft 14 drives the clamping plate 1401 to move synchronously until it abuts against the plastic part, so as to achieve the clamping operation of the plastic part.

[0059] Please see Figure 4 The rotating component includes a support frame 7 fixedly mounted on the base 1, and an annular component 8 rotatably mounted on the support frame 7. The inner ring of the annular component 8 has bevel teeth that mesh with the first bevel gear set 16 distributed along the circumference, and the outer ring has locking teeth distributed along the circumference.

[0060] It also includes a first connecting shaft 10 rotatably mounted on the base 1, and the first connecting shaft 10 is provided with a first gear 9 that meshes with the locking teeth.

[0061] Under the action of the gap drive, when the clamping member is fully clamped on the plastic part, the first connecting shaft 10 is driven to rotate. When the first connecting shaft 10 rotates, the first gear 9 on it drives the snap teeth on the ring part 8 to realize the rotation requirement of the ring part 8. When the ring part 8 rotates, under the action of the first bevel gear 16, it drives the plug-in cylinder 15 to rotate, so that the clamped plastic part follows the rotation to realize the inspection work of the plastic part.

[0062] Please see Figure 7 , Figure 8 , Figure 9The intermittent drive component includes a lead screw 23 rotatably mounted on the base 1. The lead screw 23 is driven to rotate by a motor 33 fixedly mounted on the base 1. A threaded sleeve 29 is threadedly connected to the lead screw 23, and the threaded sleeve 29 is slidably connected to the base 1.

[0063] It also includes a pusher, a first transmission member and a second transmission member disposed on the base 1, wherein the pusher, the first transmission member and the second transmission member are connected to the threaded sleeve 29.

[0064] When the plastic part to be inspected is moved to the area to be inspected, the motor 33 is started. When the motor 33 is working, it drives the output shaft to rotate. When the output shaft rotates, it drives the lead screw 23 to rotate synchronously. When the lead screw 23 rotates, it drives the threaded sleeve 29 to move linearly along the axis of the lead screw 23. Under the action of the threaded sleeve 29, the pusher, the first transmission component and the second transmission component are driven to work respectively to complete the inspection of the plastic part.

[0065] The pusher includes a first drive shaft 22 rotatably mounted on the base 1. A first limiting groove is formed on the first drive shaft 22. A first connecting sleeve 30 fixedly connected to the threaded sleeve 29 is sleeved on the first drive shaft 22. A first ball 3001 that rolls with the first limiting groove is movably disposed in the first connecting sleeve 30.

[0066] It also includes a turntable 21, which is fixedly connected to the first transmission shaft 22. The turntable 21 has a protrusion 2101 at the eccentric position that slides in cooperation with the limiting groove 1901.

[0067] The first transmission component includes a second transmission shaft 24 rotatably mounted on the base 1. The second transmission shaft 24 is connected to the support shaft 11 via a third bevel gear set 34. A second limiting groove is formed on the second transmission shaft 24. A second connecting sleeve 31, which is fixedly connected to the threaded sleeve 29, is sleeved on the second transmission shaft 24. A second ball bearing 3101, which rolls and engages with the second limiting groove, is movably disposed inside the second connecting sleeve 31.

[0068] The second transmission component includes a third transmission shaft 25 rotatably mounted on the base 1. The third transmission shaft 25 is connected to a second connecting shaft 27 rotatably mounted on the base 1 via a second bevel gear set 26. The second connecting shaft 27 is connected to a first connecting shaft 10 via a belt 28. A third limiting groove is formed on the third transmission shaft 25. A third connecting sleeve 32, which is fixedly connected to the threaded sleeve 29, is sleeved on the third transmission shaft 25. A third ball bearing 3201, which is movably disposed in the third connecting sleeve 32 and rolls with the third limiting groove, is also provided in the third connecting sleeve 32.

[0069] The first limiting groove is composed of multiple A-threaded grooves and B-straight grooves, the second limiting groove is composed of C-threaded grooves and D-straight grooves, and the third limiting groove is composed of E-threaded grooves and F-straight grooves.

[0070] When the threaded sleeve 29 moves, it drives the first connecting sleeve 30 to move synchronously. When the first ball 3001 moves into the A threaded groove, it generates an inclined squeezing force on the first drive shaft 22, causing the first drive shaft 22 to rotate. When the first drive shaft 22 rotates, it drives the turntable 21 to rotate synchronously. The protrusion 2101 on the turntable 21 slides relative to each other in the limiting slide groove 1901, squeezing the movable plate 19 to meet the reciprocating movement requirement of the movable plate 19. At this time, the movable plate 19 moves downward. When the clamping plate 1401 abuts against the plastic part and completes the clamping, the first ball 3001 moves into the B straight groove. At this time, the first drive shaft 22 stops rotating.

[0071] Simultaneously, when the threaded sleeve 29 moves, it drives the first connecting sleeve 30, the second connecting sleeve 31, and the third connecting sleeve 32 to move synchronously. When the first ball 3001 moves into the A threaded groove, the second ball 3101 moves into the D straight groove, and the third ball 3201 moves into the F straight groove. At this time, the first drive shaft 22 rotates, while the second drive shaft 24 and the third drive shaft 25 stop rotating. When the first ball 3001 moves into the B straight groove, the second ball 3101 is still moving in the D straight groove, while the third ball 3201 moves into the E threaded groove. When the third ball 3201 moves into the E threaded groove, it exerts an inclined squeezing force on the third drive shaft 25, causing the second drive shaft 24 to rotate. Under the action of the second bevel gear set 26, it drives the second connecting shaft 27 to rotate. When the second connecting shaft 27 rotates, it performs the function of the first connecting shaft 10 under the action of the belt 28, thus fulfilling the requirement of driving the rotating parts to work.

[0072] As the threaded sleeve 29 continues to move, the first ball 3001 moves to the A threaded groove. At this time, the second ball 3101 moves to the D straight groove, and the third ball 3201 moves to the F straight groove. The clamping component then opens the plastic part. After the clamping component returns to its original position, the first ball 3001 moves to the B straight groove, and the second ball 3101 moves to the C threaded groove. The second ball 3101 exerts an inclined squeezing force on the second drive shaft 24, causing the second drive shaft 24 to rotate. Under the action of the third bevel gear set 34, the support shaft 11 rotates. However, the rotation angle of the support shaft 11 is limited and cannot be equal to 180 degrees to prevent the clamping component from rotating back to its initial state.

[0073] In summary, when the support shaft 11 rotates, it drives the clamping assembly on it to rotate synchronously. When the support shaft 11 stops rotating, the clamping assembly repeats the previous operation, clamping and rotating the plastic part to achieve comprehensive inspection of the plastic part and avoid blind spots during inspection, which may cause inspection errors.

[0074] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
