In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0029] See also Figure 1 to Figure 9 In an embodiment of the present invention, a method for detecting automobile plastic parts includes the following steps: Step 1: Place the plastic part in the area to be tested; Step 2: Use the detection device to detect the plastic parts; Step 3: The detection device transmits the collected information to the computer; Step 4: The computer compares and analyzes the transmitted information with the image of the qualified plastic parts to determine whether it is qualified The detection device comprises a base 1 and a rotating member arranged on the base 1; It also includes a clamping mechanism installed on the base 1, the clamping mechanism includes a support shaft 11 and a clamping unit 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, and when performing the clamping work, the rotating member controls the clamping member to rotate; The intermittent driving member is installed on the base 1, and connects the clamping member, the rotating member and the supporting shaft 11. After the plastic member completes the unidirectional rotation, the supporting shaft 11 is controlled to rotate to change the clamping position of the plastic member by the clamping member.

[0030] In detail, in the present invention, the automobile plastic parts detection method described in the present invention is adopted. When in use, the plastic parts are first placed in the area to be detected, and the gap driving part is started to work, and the clamping part is controlled to clamp the plastic parts, and then the rotating part is driven to work, so that the transmission clamping part drives the plastic parts to rotate to realize the detection of the plastic parts, and then the clamping part stops rotating and opens and resets the plastic parts. Under the action of the gap driving part, the support shaft 11 rotates to drive the clamping part to rotate synchronously. When the clamping part clamps and rotates the plastic parts again, the clamping position changes to realize the comprehensive detection of the plastic parts and improve the accuracy of the detection.

[0031] See also Figure 2 , Figure 3The base 1 is symmetrically provided with guide rails 2, on which the first receiving frame 3 and the second receiving frame 4 are slidingly provided respectively, the first receiving frame 3 is fixedly connected with a conveying member 6, the second receiving frame 4 is fixedly connected with a visual detector 5, and the first receiving frame 3 and the second receiving frame 4 are fixedly provided.

[0032] The above-mentioned conveying member 6 conveys the plastic part to the position to be inspected. After the clamping member clamps the plastic part, the first receiving frame 3 and the second receiving frame 4 move synchronously. At this time, the visual detector 5 is located above the area to be inspected to inspect the plastic part. While the clamping member opens the plastic part, the conveying member 6 moves again to the top of the plastic part to receive it to prevent the plastic part from falling and affecting the subsequent inspection work.

[0033] See also Figure 5 , Figure 6 The clamping unit includes a support plate 12 fixedly mounted on the support shaft 11, a through slot is symmetrically formed on the support plate 12, a slider 13 is slidably arranged in the through slot, and a telescopic member is connected to the slider 13; It also includes a sleeve 18 slidably arranged on the support shaft 11, the sleeve 18 is arranged along the axial direction of the support shaft 11, a movable plate 19 is rotatably installed on the sleeve 18, the movable plate 19 is slidably arranged on the base 1 through a guide rod 20, a limited position slide groove 1901 is formed on the movable plate 19, and a hinge rod 17 is rotatably installed on the sleeve 18, and the end of the hinge rod 17 away from the sleeve 18 is rotatably connected to the slider 13.

[0034] To elaborate, when the gap driving member is started to work, the reciprocating movement of the movable plate 19 is realized under the transmission action of the pushing member. 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 is directional sliding in the through groove. When the slider 13 moves, it drives the telescopic member on it to slide synchronously to realize the clamping of the plastic part.

[0035] See also Figure 6 The telescopic member includes a plug-in cylinder 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 cylinder 15; It also includes a movable shaft 14 rotatably mounted on the slider 13 , one end of the movable shaft 14 is slidably disposed in the plug-in tube 15 , and the other end is fixedly connected with a clamping plate 1401 .

[0036] When the slider 13 moves, it drives the movable shaft 14 to move synchronously, wherein at least one strip groove 1501 is formed in the plug-in tube 15, and a strip slider 1402 is formed on the movable shaft 14 to slide with the strip groove 1501. When the movable shaft 14 moves, it drives the strip slider 1402 to move synchronously. Under the limiting action of the strip groove 1501 and the strip slider 1402, the sliding connection between the movable shaft 14 and the plug-in tube 15 is realized, and the synchronous rotation of the movable shaft 14 is driven by the rotation of the plug-in tube 15 without affecting the synchronous rotation of the movable shaft 14. The movable shaft 14 drives the clamping plate 1401 to move synchronously until it abuts against the plastic part to realize the clamping of the plastic part.

[0037] See also Figure 4 The rotating member includes a support frame 7 fixedly mounted on the base 1, and a ring member 8 is rotatably mounted on the support frame 7. The inner ring of the ring member 8 is provided with bevel teeth meshing with the first bevel gear set 16 along the circumference, and the outer ring is provided with latch teeth along the circumference; 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 meshing with the latching teeth.

[0038] Under the action of the gap driving member, when the clamping member completely clamps the plastic part, the first connecting shaft 10 is driven to rotate. When the first connecting shaft 10 rotates, the first gear 9 thereon and the latching teeth on the ring member 8 are transmitted to realize the rotation requirement of the ring member 8. When the ring member 8 rotates, under the action of the first bevel gear 16, the plug-in cylinder 15 is driven to rotate, so that the clamped plastic part follows the rotation to realize the detection of the plastic part.

[0039] See also Figure 7 , Figure 8 , Fig. 9 The intermittent driving member includes a screw rod 23 rotatably mounted on the base 1, the screw rod 23 is driven to rotate by a motor 33 fixedly mounted on the base 1, a threaded sleeve 29 is threadedly connected to the screw rod 23, and the threaded sleeve 29 is slidably connected to the base 1; It also includes a pushing member, a first transmission member and a second transmission member arranged on the base 1 , and the pushing member, the first transmission member and the second transmission member are connected to the threaded sleeve 29 .

[0040] When the plastic part to be inspected moves to the area to be inspected, the motor 33 is started to work. When the motor 33 is working, it drives the output shaft to rotate. When the output shaft rotates, it drives the screw rod 23 to rotate synchronously. When the screw rod 23 rotates, it drives the threaded sleeve 29 to make a linear motion along the axial direction of the screw rod 23. Under the action of the threaded sleeve 29, the pushing member, the first transmission member and the second transmission member are driven to work respectively to complete the inspection of the plastic part.

[0041] The pushing member includes a first transmission shaft 22 rotatably mounted on the base 1, a first limiting groove is formed on the first transmission shaft 22, a first connecting sleeve 30 fixedly connected to the threaded sleeve 29 is sleeved on the first transmission shaft 22, and a first ball 3001 rollingly matched with the first limiting groove is movably arranged in the first connecting sleeve 30; It also includes a turntable 21, which is fixedly connected to the first transmission shaft 22, and a protruding column 2101 that slidably cooperates with the limiting sliding groove 1901 is provided at an eccentric position of the turntable 21.

[0042] The first transmission member includes a second transmission shaft 24 rotatably mounted on the base 1, the second transmission shaft 24 is connected to the support shaft 11 through a third bevel gear set 34, a second limiting groove is formed on the second transmission shaft 24, a second connecting sleeve 31 fixedly connected to the threaded sleeve 29 is sleeved on the second transmission shaft 24, and a second ball 3101 rollingly engaged with the second limiting groove is movably arranged in the second connecting sleeve 31.

[0043] The second transmission member 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 through a second bevel gear set 26, the second connecting shaft 27 is connected to the first connecting shaft 10 through a belt 28, a third limiting groove is formed on the third transmission shaft 25, a third connecting sleeve 32 fixedly connected to the threaded sleeve 29 is sleeved on the third transmission shaft 25, and a third ball 3201 rollingly matched with the third limiting groove is movably arranged in the third connecting sleeve 32.

[0044] Among them, the first limiting groove is composed of multiple sections of A thread grooves and B straight grooves, the second limiting groove is composed of C thread grooves and D straight grooves, and the third limiting groove is composed of E thread grooves and F straight grooves.

[0045] 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 transmission shaft 22, causing the first transmission shaft 22 to rotate. When the first transmission shaft 22 rotates, it drives the turntable 21 to rotate synchronously. The convex column 2101 on the turntable 21 slides relatively in the limiting slide groove 1901, squeezing the movable plate 19 to achieve the reciprocating movement of the movable plate 19. At this time, the movable plate 19 moves downward, and when the clamping plate 1401 abuts against the plastic part and completes the clamping, the first ball 3001 moves to the B straight groove, and the first transmission shaft 22 stops rotating.

[0046] At the same time, 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 thread 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 transmission shaft 22 rotates, while the second transmission shaft 24 and the third transmission shaft 25 stop rotating. When the first ball 3001 moves to the B straight groove, the second ball 3101 still moves in the D straight groove, and the third ball 3201 moves to the E thread groove at this time. When the third ball 3201 moves into the E thread groove, the third ball 3201 generates an inclined squeezing force on the third transmission shaft 25, causing the second transmission shaft 24 to rotate. Under the action of the second bevel gear set 26, the second connecting shaft 27 is driven to rotate. When the second connecting shaft 27 rotates, under the action of the belt 28, the function of the first connecting shaft 10 is realized to achieve the demand of driving the rotating part to work.

[0047] Among them, when the threaded sleeve 29 continues to move, driving the first ball 3001 to continue to move to the A thread groove, the second ball 3101 moves to the D straight groove, and the third ball 3201 moves to the F straight groove. At this time, the clamping part opens the plastic part. After the clamping part is reset, the first ball 3001 moves to the B straight groove, and the second ball 3101 moves to the C thread groove. The second ball 3101 generates an inclined squeezing force on the second transmission shaft 24, causing the second transmission shaft 24 to rotate. Under the action of the third bevel gear set 34, the support shaft 11 is rotated, and the rotation angle of the support shaft 11 is limited and cannot be equal to 180 degrees, so as to prevent the clamping part from rotating to the initial state.

[0048] In general, when the support shaft 11 rotates, the clamping assembly thereon is driven to rotate synchronously. When the support shaft 11 stops rotating, the clamping member repeats the last work, clamps the plastic part and rotates it to achieve comprehensive inspection of the plastic part, avoiding blind spots during inspection and causing the possibility of inspection errors.

[0049] It will be apparent to those skilled in the art that the 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 the spirit or essential features of the invention.
