Description

Technical Field

[0001] The invention relates to the technical field of automobile interior decoration parts, in particular to an automobile interior decoration part assembly positioning platform. Background Art

[0002] Interior trim generally refers to car interior components and materials such as partitions, door trim panels, instrument panel assemblies, armrests, and carpets. Compared to other car components, they have little impact on the vehicle's operating performance, but they are the most prominent feature and represent the overall image of the car. Their quality determines the reputation and grade of the car, and determines people's willingness to choose a car. In addition, for cars, although interior trim is only some auxiliary parts, it has to assume functions such as vibration reduction, heat insulation, sound absorption and sound insulation, and plays a very important role in the comfort of the car.

[0003] For some frame-type interiors, their appearance needs to be inspected before they are produced and shipped. Specifically, it is necessary to detect whether there are cracks after the screws are installed on the outside of the interior parts, so as to classify defective products. Traditional inspection methods mostly rely on manual observation, which has low inspection efficiency, and some fine cracks cannot be found by the naked eye. Therefore, it is necessary to provide an automotive interior parts assembly positioning platform to solve the above problems. Summary of the Invention

[0032] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] refer to Figures 1 to 11 The illustrated automobile interior trim assembly positioning platform comprises:

[0034] A square positioning platform 1 for horizontally supporting interior decoration parts, wherein the square positioning platform 1 has a plurality of positioning members located near the center of the square positioning platform 1 and playing a preliminary positioning role for the interior decoration parts;

[0035] The clamping mechanism is provided on the square positioning platform 1. The clamping mechanism includes a plurality of clamping blocks 2 arranged in sequence along the outer edge of the square positioning platform 1. The plurality of clamping blocks 2 can be synchronously displaced toward the center of the square positioning platform 1 to clamp the four sides of the interior decoration part.

[0036] Several groups of detection components are fixedly arranged in sequence along the outer edge of the square positioning platform 1, and each group of detection components includes a two-axis displacement mechanism, an appearance detection head 3 and a laser detection head 4. The two-axis displacement mechanism has a horizontal displacement end that can be horizontally displaced toward the center of the square positioning platform 1 and a vertical displacement end arranged on the horizontal displacement end. The appearance detection head 3 and the laser detection head 4 are distributed at intervals in the vertical direction, and the two are arranged on the vertical displacement end of the two-axis displacement mechanism through a flap 5 that can be flipped 180°. The laser detection head 4 is used to detect whether screws are installed on the corresponding outer edge of the interior decoration part, and the appearance detection head 3 is used to detect whether there are cracks on the peripheral part of the outer edge of the interior decoration part where screws are installed.

[0037] Each positioning member is a column 7 fixed to the top of the square positioning platform 1 by a horizontal fixing plate 6. Several horizontal fixing plates 6 support the interior decoration parts. Two of the columns 7 correspond to the two inner end corners of the interior decoration parts one by one, and the surrounding walls of the remaining columns 7 all conflict with one of the inner side edges of the interior decoration parts.

[0038] The interior trim parts targeted by this device are rectangular frames;

[0039] Before installing the pillars 7, first measure the span distance of the inner circle of the interior trim. Then, based on the measured value, several pillars 7 are fixed in a matrix arrangement on the top of the square positioning platform 1. After the interior trim is placed, two of the pillars 7 can correspond to the two inner end corners of the interior trim, and the surrounding walls of the remaining pillars 7 can all contact one of the inner side edges of the interior trim. This is to pre-position the interior trim before it is clamped.

[0040] When processing the horizontal fixing plate 6, the horizontal fixing plate 6 needs to be processed to a certain thickness so that the column 7 can be fixedly installed on the top of the square positioning platform 1 through the horizontal fixing plate 6. The square positioning platform 1 can have several supporting steps flush with the top, and the interior decoration parts are placed directly horizontally on several horizontal fixing plates 6.

[0041] A number of strip slides 8 are provided in sequence along the circumference direction of the outer edge of the square positioning platform 1. The length direction of each strip slide 8 is perpendicular to the corresponding side of the square positioning platform 1. A number of clamping blocks 2 correspond to a number of strip slides 8 one by one. Each clamping block 2 is strip-shaped and its length direction is consistent with the length direction of the corresponding strip slide 8. The bottom of each clamping block 2 is connected to a slider 9 that slides with the corresponding strip slide 8 through a connecting piece. The bottom of each slider 9 is flush with the bottom of the square positioning platform 1. The bottom of the square positioning platform 1 is provided with a driving mechanism for driving a number of sliders 9 to slide back and forth synchronously in the corresponding strip slide 8.

[0042] When the driving mechanism is started, several sliders 9 can slide back and forth synchronously in the corresponding strip-shaped slide grooves 8. When several sliders 9 slide synchronously toward the center of the square positioning platform 1, the clamping blocks 2 connected to the sliders 9 through connecting parts can all contact with the corresponding outer edges of the interior decoration parts. Finally, the four sides of the interior decoration parts are pressed tightly together through the contact action of all the sliders 9 distributed around the interior decoration parts.

[0043] The driving mechanism includes:

[0044] The first stepper motor 10 is vertical and connected to the bottom of the square positioning platform 1 through a cross connecting plate 11 spaced apart from the bottom of the square positioning platform 1. The output shaft of the first stepper motor 10 passes vertically upward through the cross connecting plate 11.

[0045] The turntable 12 is coaxially connected to the output shaft of the first stepper motor 10 and is located between the square positioning platform 1 and the cross connecting plate 11;

[0046] A plurality of horizontal pull rods 13 corresponding to the strip chute 8 are provided. One end of each horizontal pull rod 13 is axially connected to the outer edge of the turntable 12 , and the other end of each horizontal pull rod 13 is axially connected to the bottom of the corresponding slider 9 .

[0047] The No. 1 stepper motor 10 stops after rotating a certain angle each time. When the No. 1 stepper motor 10 is started, the turntable 12 will be driven by the No. 1 stepper motor 10 to rotate in one direction. When the turntable 12 rotates, it will pull one end of all the horizontal pull rods 13 to rotate to one side, so that the other end of each horizontal pull rod 13 will pull the corresponding slider 9 to move in the strip slide 8. If the slider 9 moves toward the center of the square positioning platform 1 in the corresponding strip slide 8 at this time, several clamping blocks 2 will clamp the interior decoration. After the inspection component is completed, the No. 1 stepper motor 10 is reversed to drive each slider 9 to move in the opposite direction, so that the interior decoration that has been inspected can be removed.

[0048] Each two-axis displacement mechanism includes a No. 1 screw slide 14 and a No. 2 screw slide 15. The No. 1 screw slide 14 is horizontally fixed on the corresponding side of the square positioning platform 1. The axial direction of the screw in the No. 1 screw slide 14 is perpendicular to the corresponding side of the square positioning platform 1, and the screw in the No. 1 screw slide 14 is driven to rotate by the No. 1 turning handle 16. The No. 2 screw slide 15 is vertically fixed on the sliding end of the No. 1 screw slide 14, and the screw in the No. 2 screw slide 15 is driven to rotate by the No. 2 turning handle 17. Among them, the sliding end of each No. 1 screw slide 14 is the horizontal displacement end corresponding to the above-mentioned two-axis displacement mechanism, and the sliding end of each No. 2 screw slide 15 is the vertical displacement end corresponding to the above-mentioned two-axis displacement mechanism.

[0049] The number of the No. 1 screw slide 14 is consistent with the number of all the screws on the outer side of the interior decoration part. When processing the No. 1 screw slide 14, a concave seat 25 that can be laterally inserted into the outer side of the square positioning platform 1 is processed on one end of the slide in the No. 1 screw slide 14, and a threaded rod 26 with one end that can be tightly abutted against the side wall or bottom of the square positioning platform 1 is screwed on the part where the concave seat 25 and the square positioning platform 1 fit together. By rotating the threaded rod 26, the No. 1 screw slide 14 is detachably connected to the square positioning platform 1. After the interior decoration part is clamped, the No. 1 screw slide 14 is fixed to the side of the square positioning platform 1 in sequence, so that the current laser detection head 4 is facing the screw installed on the outer side of the interior decoration part;

[0050] After the No. 1 screw slide 14 is installed, the No. 1 turning handle 16 can be used to adjust the horizontal distance between the corresponding No. 2 screw slide 15 and the interior decoration part, thereby adjusting the horizontal distance between the appearance inspection head 3 and the laser inspection head 4 and the outer edge of the interior decoration part to adapt to the inspection of interior decoration parts of different specifications. The larger the specifications of the interior decoration part, the smaller the horizontal distance between the appearance inspection head 3 and the laser inspection head 4. Therefore, the No. 1 turning handle 16 is used to adjust the horizontal distance between the appearance inspection head 3 and the laser inspection head 4 and the interior decoration part to the optimal distance for inspection;

[0051] Since the screws on the outer sides of interior parts of different specifications are located in different positions and may deviate from the previous screws in the vertical direction, the vertical distance between the appearance inspection head 3 and the laser inspection head 4 is adjusted by the second turning handle 17 to ensure that the appearance inspection head 3 and the laser inspection head 4 can both detect the screws directly after being rotated by the flap 5. If the screws on the interior parts to be inspected subsequently deviate in the horizontal direction, the entire No. 1 screw slide 14 is adjusted by loosening the above-mentioned threaded rod 26;

[0052] The appearance detection head 3 can be a camera. Since the camera has a large capture range, when the first screw slide 14 is installed for the first time, the laser detection head 4 is facing the screw on the outer side of the interior decoration part.

[0053] The sliding end of the No. 2 screw slide 15 is connected to a support arm 18 extending horizontally toward the center of the square positioning platform 1. A vertical connecting plate 19 is fixedly connected to one end of the support arm 18 facing the center of the square positioning platform 1. Each flip plate 5 is vertically rotatable and is arranged on the side of the corresponding vertical connecting plate 19 facing the center of the square positioning platform 1. The other side of each vertical connecting plate 19 is fixed with a No. 2 stepper motor 20 which is horizontal and used to drive the flip plate 5 to rotate. Each appearance inspection head 3 and laser inspection head 4 are respectively fixed on the side of the corresponding flip plate 5 facing the center of the square positioning platform 1, and each appearance inspection head 3 and laser inspection head 4 are respectively located at both ends of the corresponding flip plate 5.

[0054] After the No. 1 screw slide 14 is installed, the No. 2 turning handle 17 is used to adjust the vertical distance of the entire flap 5 so that the laser detection head 4 provided at one end of the flap 5 is facing the screw on the outer side of the interior decoration part. Then, each laser detection head 4 detects whether a screw is installed at the position where the screw should be installed on the corresponding side of the interior decoration part. The laser detection head 4 detects the horizontal distance between its laser generating end and the screw. If the screw is not installed, the value displayed by the laser detection head 4 through the host computer (not shown in the figure) should be greater than the value of other screws installed.

[0055] After the laser inspection head 4 has completed the inspection, the second stepper motor 20 is started to rotate the flap 5 180 degrees, and the appearance inspection head 3 is flipped back to the original position of the laser inspection head 4. The appearance inspection head 3 then takes a picture of the outer edge of the interior decoration screw to check whether there are any cracks on the outer periphery of the interior decoration screw.

[0056] Since the capture range of the appearance inspection head 3 is large, no matter what the specifications of the subsequent interior parts are, as long as the laser inspection head 4 is facing the location where the screws are installed in advance, the appearance inspection head 3 after the flap 5 is flipped over can take pictures and inspect the location where the screws are installed on the interior parts.

[0057] Each connecting member is an I-shaped connecting block 21, the bottom of the connecting block 21 is fixedly connected to the top of the corresponding slider 9, and the top of the connecting block 21 is fixedly connected to the bottom of the corresponding clamping block 2. The bottom of the connecting block 21 is formed with two auxiliary slides 22 located on both sides of the corresponding slider 9. The length direction of each auxiliary slide 22 is consistent with the length direction of the corresponding strip slide 8. A number of auxiliary slides 23 are provided on the top of the square positioning platform 1 for the auxiliary slides 22 to slide.

[0058] The auxiliary slide bar 22 is used to cooperate with the sliding of the slider 9, so that the sliding of the clamping block 2 is smoother. The slider 9 is connected to the slider 9 by an I-shaped connecting block 21, which makes the connection more stable.

[0059] A vertically upward abutment plate 24 is formed on one end of each clamping block 2 facing the center of the square positioning platform 1 .

[0060] The contact plate 24 increases the contact area between the clamping block 2 and the interior trim, preventing the end of the clamping block 2 from directly and rigidly contacting the outer edge of the interior trim and scratching the outer side of the interior trim. A rubber layer can be added to one side of the contact plate 24 near the center of the square positioning platform 1 to avoid rigid contact between the contact plate 24 and the outer side of the interior trim.

[0061] Working principle:

[0062] First, place the interior decoration part horizontally on several horizontal fixing plates 6 on the top of the square positioning platform 1, and use the columns 7 on each horizontal fixing plate 6 to contact the inner circle of the interior decoration part to achieve the initial positioning of the interior decoration part. Then start the No. 1 stepper motor 10, and drive the turntable 12 to rotate a certain angle through the No. 1 stepper motor 10. At this time, the turntable 12 will pull each horizontal pull rod 13 to push and pull the corresponding slider 9. If the slider 9 moves toward the center of the square positioning platform 1, the clamping block 2 connected to the slider 9 will clamp the four sides of the interior decoration part. After that, The laser inspection head 4 inspects the outer edge of the interior decoration parts. The laser inspection head 4 is used to detect whether screws are installed at the parts on the outer edge of the interior decoration parts where screws should be installed. After the laser inspection head 4 detects, the No. 2 stepper motor 20 is started to drive the flap 5 to rotate so that the appearance inspection head 3 rotates to the original position of the laser inspection head 4. The appearance inspection head 3 is used to detect whether there are cracks at the parts on the outer edge of the interior decoration parts where screws are installed. After all the interior decoration parts are inspected, the No. 1 stepper motor 10 is reversed to make all the clamping blocks 2 in the clamped state slide in the opposite direction, and then the interior decoration parts are removed.

[0063] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
