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 function of automatic sampling inspection, 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 slidably 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 body 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, thereby driving the translation plate 103, the lifting plate 101 and the door trim body to move horizontally.

[0046] A pair of concave cross bars 203 are provided at both ends of the handling and sampling inspection chamber 4, and both ends of the concave cross bar 203 are fixedly connected to the handling and sampling inspection chamber 4, the upper end of the concave cross bar 203 is slidably matched with the transport platform 202, and the transport platform 202 is slidably matched with the translation plate 103, and the two ends of the transport platform 202 are fixedly connected with side plates 204, and the inner side of the side plate 204 is fixedly connected with a limiting plate 205, and the limiting plate 205 slides in the groove of the concave cross bar 203, and the limiting plate 205 penetrates and opens an inclined groove 401, and the concave cross bar 203 penetrates and opens a vertical groove 402, and the upper end of the lifting plate 101 is fixedly connected with a triangular seat 104, and the inner side of the triangular seat 104 penetrates and is fixedly connected with a limiting rod 105, and the limiting rod 105 passes through the vertical groove 402 and the inclined groove 401 and moves along them, and the highest points of the vertical groove 402 and the inclined groove 401 are on the same horizontal line.

[0047] Preferably, the limiting rod 105 is arranged to pass through the vertical slot 402 and the inclined slot 401. In the initial state, the limiting rod 105 is at the top of the vertical slot 402 and the inclined slot 401 (eg 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 side plate 204 and the limit plate 205 are driven to move toward the starting end of the transport sampling inspection chamber 4 through the transport platform 202, that is, the inclined slot 101 is displaced relative to the vertical slot 102. At this time, the limit rod 105 is limited 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 be moved downward and the door trim body to be inspected can be adsorbed;

[0048] When the adsorption is completed and needs to be reset, the transport platform 202 is immediately displaced 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 detach 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, and the limit rod 105 can be displaced along the horizontal groove 403, thereby driving the door trim panel body to move horizontally, realizing a 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] The concave horizontal bar 203 is penetrated by a second inclined groove 404 , which has the same slope and length as the first inclined groove 401 , and the upper end of the second inclined groove 404 is connected to the horizontal groove 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, and under the action of gravity, the limit rod 105 moves downward along the two inclined grooves, so that the door trim panel body can be lowered onto the conveyor belt 7, realizing the seamless connection of the horizontal displacement and descent of the door trim panel body.

[0053] The limiting plate 205 is provided with a second vertical slot 405 , the lower end of the second vertical slot 405 is connected with the first inclined slot 401 , and 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 405, the limit rod 105 rises synchronously along the inclined groove 404 and the vertical groove 405 until it moves into the transverse groove 403. The lifting plate 101 can be lifted and reset, and displaced along the transverse groove 403 until the vertical groove 1 402 and the vertical groove 2 405 overlap with each other. The limit rod 105 can then 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 with a plurality of guide posts 302, the upper end of the guide posts 302 is fixedly connected with 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 with 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 a collecting plate 305. 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 formed 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 rollers 108 are driven to 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 continuously rotates to drive a pair of rollers 108 to move in a circle. When the rollers 108 come into contact with 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 matched 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 . The straight keys 207 are slidably matched 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 restricted 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 simultaneously performs continuous impact tests on the door trim panel body, which has a high degree of automation and saves costs.
