[0027] Referring to the drawings Figs. 1-4 A material shortage detection device for automobile roof production, comprising a bottom plate 1, a main conveyor 2 and an auxiliary conveyor 3 are arranged on the bottom plate 1, the main conveyor 2 is used for conveying a base material, the auxiliary conveyor 3 is used for conveying a fabric, the conveying direction of the auxiliary conveyor 3 is perpendicular to the conveying direction of the main conveyor, a three-axis displacement assembly 4 is arranged on the bottom plate 1, a detection mechanism 7 and an angle adjusting mechanism 8 are arranged on the output end of the three-axis displacement assembly 4, a fixing mechanism 6 is arranged on the output end of the angle adjusting mechanism 8, the fixing mechanism 6 is used for adsorbing and fixing the fabric conveyed on the auxiliary conveyor 3, and then transferring the fabric to above the base material on the main conveyor 2 through the three-axis displacement assembly 4.

[0028] The three-axis displacement assembly 4 comprises two supporting frames 41 symmetrically arranged on the bottom plate 1, one X-axis moving module 42 is arranged on each of the two supporting frames 41, and a Y-axis moving module 43 is fixedly installed between the output ends of the two X-axis moving modules 42, and a Z-axis moving module 44 is arranged on the output end of the Y-axis moving module 43.

[0029] The angle adjusting mechanism 8 comprises an L-shaped mounting block 81 fixed on the Z-axis moving module 44, a rotating shaft 82 is rotatably installed on the L-shaped mounting block 81 through a bearing, a driven gear 83 is fixedly installed on the upper end of the rotating shaft 82, the lower end of the rotating shaft 82 is connected with the fixing mechanism 6, an adjusting motor 85 is fixedly installed on the L-shaped mounting block 81, a driving gear 84 is fixedly installed on the motor shaft of the adjusting motor 85, and the driving gear 84 is engaged with the driven gear 83. The number of teeth of the driving gear 84 is less than the number of teeth of the driven gear 83, forming a speed reduction ratio, so that the fabric rotates more stably and avoids shaking.

[0030] The fixing mechanism 6 comprises a connecting plate 61 fixed on the lower end of the rotating shaft 82, a mounting frame 62 is fixedly arranged on the lower end of the connecting plate 61, a plurality of T-slots 63 are arranged on the mounting frame 62, and vacuum suction cups 64 are installed in the T-slots 63. The fixing mechanism 6 adopts the layout of the vacuum suction cups 64 matched with the T-slots 63, the positions of the vacuum suction cups 64 can be adjusted according to the size of the fabric, different specifications of fabrics can be gripped, the auxiliary conveyor 3 is arranged vertically with the main conveyor 2, space is saved, the production line is compactly arranged, and the workshop space utilization rate is improved.

[0031] A detection camera one 5 is arranged above the main conveyor 2, and the detection mechanism 7 comprises a camera mounting frame 71 fixed on an L-shaped mounting block 81, and a detection camera two 72 is arranged on the camera mounting frame 71, and a detection sensor 73 is further arranged in the slot 63. The detection camera one 5 covers the base material, the detection camera two 72 covers the fabric, and the detection sensor 73 monitors the grabbing state in real time, forms a “material-grabbing-laminating” whole process detection, combines visual detection and sensor detection, and makes up for the limitations of single detection mode. For example, the recognition blind area of visual to small material defects can be supplemented by sensor tension detection.

[0032] Working principle:

[0033] The main conveyor 2 continuously operates along the transverse direction (Y-axis direction in the embodiment), and the base material (such as a hard framework or a base material) of the automobile roof is conveyed. The base material moves to the designated work station along with the conveyor belt. The auxiliary conveyor 3 conveys the fabric (such as a soft covering material) along the longitudinal direction (X-axis direction) perpendicular to the main conveyor, and the fabric is arranged on the conveyor belt at a set interval and direction, waiting for grabbing.

[0034] Two symmetrical support frames 41 are fixed on the bottom plate 1, and an X-axis moving module 42 on the support frames 41 drives a Y-axis moving module 43 to move along the X-axis direction, so that the whole displacement mechanism is positioned to the target fabric area above the auxiliary conveyor 3. The Y-axis moving module 43 is further adjusted along the Y-axis direction, and the Z-axis moving module 44 is in the initial high position to avoid interference with the auxiliary conveyor.

[0035] The Z-axis moving module 44 drives the angle adjusting mechanism 8 and the fixing mechanism 6 to move downward, so that the vacuum suction cups 64 slowly approach the surface of the fabric on the auxiliary conveyor 3. A plurality of vacuum suction cups 64 are arranged in the slot 63 of the fixing mechanism 6, and the layout can be adjusted according to the size of the fabric, so as to ensure that the suction force is uniformly distributed (for example, more suction cups are used for large-size fabric, and the interval is reduced or adjusted for small-size fabric).

[0036] The vacuum system is started, the suction cups 64 generate negative pressure to adsorb the fabric, and the detection sensor 73 (such as a photoelectric sensor or a pressure sensor) in the slot 63 monitors in real time to detect whether the fabric is successfully adsorbed (by sensing the surface tension of the fabric or the change of the suction cup pressure), and to confirm whether the grabbing position is correct (to avoid incomplete grabbing due to fabric deviation). If the sensor feedback is abnormal (such as no fabric is detected or the adsorption force is insufficient), the system will issue an alarm and pause the action, waiting for manual intervention. After confirming the successful grabbing, the Z-axis moving module 44 is lifted upward to completely separate the fabric from the conveyor belt of the auxiliary conveyor 3, and the fabric is in a suspended state and is stably clamped by the fixing mechanism 6.

[0037] The motor 85 is adjusted to start, the driving gear 84 on the output shaft thereof is engaged with the driven gear 83 to rotate, the driving gear has less teeth than the driven gear, a reduction ratio is formed, for example, the driving gear has 10 teeth and the driven gear has 30 teeth, and the reduction ratio is 1:3. The driven gear 83 drives the rotating shaft 82 to rotate, thereby driving the fixing mechanism 6 and the fabric to rotate, and the angle adjustment in the range of 0°-360° is realized.

[0038] The X-axis moving module 42 and the Y-axis moving module 43 are coordinated to drive the whole mechanism to translate from above the auxiliary conveyor 3 to above the base material on the main conveyor 2. During the movement, the Z-axis moving module 44 keeps the fabric at a safe height to avoid collision with other equipment, and the position data is fed back in real time through the displacement sensor to ensure the positioning accuracy. The Z-axis moving module 44 slowly lowers the fabric to align the fabric with the surface of the base material on the main conveyor 2.

[0039] After reaching the set height, the vacuum system is closed, the vacuum chuck 64 releases the fabric, and the fabric is preliminarily attached to the base material under the action of gravity or auxiliary pressing device, and then fixed by subsequent processes (such as hot melting, sewing, etc.).

[0040] The base material detection of the detection camera one 5 is installed above the main conveyor 2 to shoot the surface of the base material in real time, identify whether the base material is missing, such as local missing or edge damage, and whether the position of the base material is deviated from the preset station.

[0041] The fabric detection of the detection camera two 72 is fixed on the L-shaped mounting block 81 of the angle adjustment mechanism, and the fabric on the auxiliary conveyor 3 is shot before the fabric is grabbed to detect whether the fabric is missing, torn or stained. The grabbing state of the detection sensor 73 is monitored to sense whether the fabric exists and whether the suction force is sufficient during the grabbing stage to avoid empty grabbing or missing transfer. For example, if the fabric in a certain area is not adsorbed by the chuck, the sensor will feed back an abnormality.

[0042] The above-described embodiments only express certain implementation manners of the present application, the description is more specific and detailed, but it cannot be understood as a limitation on the patent scope of the present application; it should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application; therefore, the protection scope of the present application patent should be subject to the appended claims.
