[0039] See also Figure 1-9 The present invention provides a technical solution: a transport inspection device for three-dimensionally wrapped automobile door trim assembly and a working method thereof, comprising a transport belt 7, a camera assembly 9 and a transport inspection chamber 4.

[0040] The conveyor belt 7 is used to transport the door trim panel body. The transport and sampling inspection chamber 4 is arranged on the upper side of the conveyor belt 7. A connecting plate 701 is provided at the upper end of the conveyor belt 7. The camera assembly 9 is arranged on the upper side of the connecting plate 701. The connecting plate 701 is located in the middle of the transport and sampling inspection chamber 4. The transport and sampling inspection chamber 4 is provided with an impact test section and a transport section.

[0041] The transport section includes a plurality of electric suction cups 1 and a linear drive assembly. The electric suction cup 1 is used to absorb the door trim panel body on the conveyor belt 7. A lifting plate 101 is provided on the upper end of the electric suction cup 1. The lifting plate 101 drives the door trim panel body to rise away from the conveyor belt 7 and dock with the impact test section. A plurality of guide telescopic rods 102 are provided on the upper end of the lifting plate 101. A translation plate 103 is provided on the upper end of the guide telescopic rod 102. The linear drive assembly drives the translation plate 103 to move along the transport inspection chamber 4, driving the door trim panel body to pass the upper side of the camera assembly 9. The camera assembly 9 records the state of the door trim panel body under test;

[0042] The impact test section includes several impact heads 3. A reciprocating plate 301 is provided on the upper side of the impact head 3. A through slot is provided at the lower end of the lifting plate 101. The reciprocating plate 301 is adapted to the through slot. The impact head 3 performs continuous impact tests on the door trim panel body.

[0043] When the door trim panel body is on the conveyor belt 7 and completes a series of production processes such as production, assembly, and coating, it moves along the conveyor belt 7 to the handling and sampling inspection room 4; specifically, when sampling inspection is required, the lifting plate 101 drives several electric suction cups 1 to descend, thereby adsorbing the door trim panel body, and rising and resetting, so that the door trim panel body contacts several impact heads 3; the reciprocating plate 301 drives the impact head 3 to move back and forth up and down, so that the impact head 3 performs continuous impact tests on the door trim panel body; then the linear drive component drives the translation plate 103 to move linearly along the handling and sampling inspection room 4, and passes through the camera component 9, and the camera component 9 records the state of the tested door trim panel body. If the surface of the door trim panel body is intact, it indicates that the quality of the door trim panel body is qualified, otherwise it is unqualified; then the lifting plate 101 drives the door trim panel body that has been inspected to descend, and unloads it back to the conveyor belt 7 through the electric suction cup 1, and then the staff removes the unqualified products to complete the automatic sampling inspection function, which is highly practical and improves work efficiency.

[0044] The linear drive assembly includes a motor part 2, which is arranged on the outside of the transport and sampling chamber 4. The motor part 2 drives a threaded rod 201, and the threaded rod 201 is rotatably connected to the inner side of the transport and sampling chamber 4. The lower end surface of the transport and sampling chamber 4 is slidingly matched with a transport platform 202. The threaded rod 201 passes through the transport platform 202 and is threadedly connected to it. The transport platform 202 drives the translation plate 103 to move.

[0045] Preferably, when it is necessary to drive the door trim panel body to pass through the camera assembly 9 for inspection, the threaded rod 201 is driven to rotate by the motor component 2, and under the guidance of a pair of long guide rods, the transport platform 202 is horizontally displaced, which can drive the translation plate 103, the lifting plate 101 and the door trim panel body to move horizontally.

[0046] The upper end of the concave cross bar 203 is provided with a pair of concave cross bars 203 at both ends of the transport and sampling inspection room 4, and the two ends of the concave cross bar 203 are fixedly connected to the transport and sampling inspection room 4, and the upper end of the concave cross bar 203 slides with the transport platform 202, and the transport platform 202 slides with the translation plate 103. The two ends of the transport platform 202 are fixedly connected to the side plates 204, and the inner sides of the side plates 204 are fixedly connected to the limit plates 205, and the limit plates 205 slide in the grooves of the concave cross bar 203. The limit plates 205 pass through the inclined slot 401, and the concave cross bar 203 passes through the vertical slot 402. The upper end of the lifting plate 101 is fixedly connected to the triangular seat 104, and the inner side of the triangular seat 104 passes through and is fixedly connected to the limit rod 105, and the limit rod 105 passes through the vertical slot 402 and the inclined slot 401 and moves along them. The highest points of the vertical slot 402 and the inclined slot 401 are on the same horizontal line.

[0047] Preferably, the limiting rod 105 is set to pass through the vertical slot 1 402 and the inclined slot 1 401. In the initial state, the limiting rod 105 is at the top of the vertical slot 1 402 and the inclined slot 1 401 (such as Figure 6 As shown in the figure, the lifting plate 101 is at the uppermost position at this time. When sampling inspection is required, the transport platform 202 drives the side plate 204 and the limit plate 205 to move toward the starting end of the transport sampling inspection chamber 4, that is, the inclined slot 101 is displaced relative to the vertical slot 102. At this time, the limit rod 105 is restricted by the vertical slot 102, and the movement of the inclined slot 101 drives the limit rod 105 to move vertically downward along the vertical slot 102, so that the lifting plate 101 can move downward and absorb the door trim panel body to be inspected.

[0048] When the adsorption is completed and needs to be reset, the transport platform 202 immediately moves in the opposite direction, driving the limit plate 205 to move toward the end of the handling and sampling chamber 4, and the inclined groove 401 drives the limit rod 105 to move vertically upward along the vertical groove 402 to reset, which can drive the door trim panel body to lift and separate from the transport belt 7, thereby realizing automatic grasping of the door trim panel body.

[0049] A transverse groove 403 is formed through the concave horizontal bar 203 , and the transverse groove 403 is connected to the upper end of the vertical groove 1 402 .

[0050] Preferably, after the door trim panel body is grabbed and lifted, the transport platform 202 continues to drive the limit plate 205 to move toward the end of the handling and sampling chamber 4. At this time, the limit rod 105 is restricted at the top of the vertical groove 402, and with the push of the inclined groove 401, it enters the horizontal groove 403. The limit rod 105 can be displaced along the horizontal groove 403, thereby driving the door trim panel body to move horizontally, realizing seamless connection between the lifting and horizontal displacement of the door trim panel body, and it can be achieved only through the horizontal displacement of the transport platform 202, which is highly practical and highly automated.

[0051] A second oblique slot 404 is formed through the concave horizontal bar 203 . The second oblique slot 404 has the same slope and length as the first oblique slot 401 . The upper end of the second oblique slot 404 is connected to the horizontal slot 403 .

[0052] Preferably, when the door trim panel body that has been inspected needs to be placed back on the conveyor belt 7, the limit plate 205 drives the limit rod 105 to move to the second inclined groove 404, so that the positions of the first inclined groove 401 and the second inclined groove 404 coincide with each other. Under the action of gravity, the limit rod 105 moves down along the two inclined grooves, and the door trim panel body can be lowered onto the conveyor belt 7, realizing seamless connection of horizontal displacement and descent of the door trim panel body.

[0053] A second vertical slot 405 is formed through the limiting plate 205 . The lower end of the second vertical slot 405 is connected to the first inclined slot 401 . The highest points of the second vertical slot 405 and the first inclined slot 401 are on the same horizontal line.

[0054] Preferably, when it is necessary to drive the lifting plate 101 to reset, the limit plate 205 is displaced in the opposite direction. At this time, the limit rod 105 is at the lower end of the two inclined grooves. Under the push of the vertical groove 2 405, the limit rod 105 rises synchronously along the inclined groove 2 404 and the vertical groove 2 405 until it moves into the horizontal groove 403. The lifting and resetting of the lifting plate 101 can be completed, and it can be displaced along the horizontal groove 403 until the vertical groove 1 402 and the vertical groove 2 405 coincide with each other. The limit rod 105 can fall again to conduct random inspection of the next door trim panel body. In other words, the lifting, horizontal displacement and lowering of the door trim panel body can be automatically achieved only through the horizontal displacement of the transport platform 202. No additional drive components or control programs are required for control. The degree of automation is high and cost is saved.

[0055] The upper end of the reciprocating plate 301 is fixedly connected to a plurality of guide posts 302, and the upper end of the guide posts 302 is fixedly connected to a fixed plate 303. The outer side of the guide posts 302 is sleeved with a spring member, and the two ends of the spring member are respectively connected to the fixed plate 303 and the lifting plate 101;

[0056] The upper end of the fixed plate 303 is in contact with a pressing block 304, which passes through the translation plate 103 and slides with it. The upper end of the pressing block 304 is fixedly connected to the collecting plate 305, and the upper end of the translation plate 103 is provided with a square groove, which slides with the collecting plate 305.

[0057] A hollow groove 106 is provided through the middle side of the transport platform 202, and a center ring 107 is rotatably connected in the hollow groove 106. Rollers 108 are provided at both ends of the center ring 107. When the center ring 107 rotates, the driving rollers 108 push the collection plate 305 downward.

[0058] Preferably, when it is necessary to drive several impact heads 3 to perform an impact test on the door trim panel body, the center ring 107 is continuously rotated to drive a pair of rollers 108 to move in a circular motion. When the rollers 108 contact the collecting plate 305, the collecting plate 305 is pushed down, thereby driving a pair of pressing blocks 304 to descend. The pressing blocks 304 push the fixing plate 303, the guide column 302 and the reciprocating plate 301 to descend, thereby driving the impact heads 3 to perform an impact test on the door trim panel body.

[0059] The threaded rod 201 passes through the center ring 107 and is loosely fitted therewith. Key slots 206 are provided at both ends of the threaded rod 201 . A pair of straight keys 207 are fixedly connected to the inner side of the center ring 107 , and the straight keys 207 are slidably fitted with the key slots 206 .

[0060] Preferably, a straight key 207 is provided to slide with the keyway 206, so that when the threaded rod 201 rotates, the torque is transmitted to drive the center ring 107 to rotate. At the same time, the threaded rod 201 rotates and also drives the transport platform 202 to move horizontally. The center ring 107 is confined in the hollow groove 106, thereby following the synchronous displacement. The transport platform 202 can drive the door trim panel body to move horizontally while the impact head 3 synchronously performs continuous impact tests on the door trim panel body, which has a high degree of automation and saves costs.
