Description

Technical Field

[0001] This utility model relates to the field of automotive leather cutting technology, specifically a cutting machine for processing automotive leather interiors. Background Technology

[0002] Automotive leather interior trim (such as seats, steering wheels, door panels, armrests, center consoles, etc.) requires large pieces of leather to be cut into the required shapes and sizes during production. Common automotive leather interior trim cutting devices include CNC vibrating knife cutting machines, CNC laser cutting machines, CNC waterjet cutting machines, and CNC die-cutting machines. Among them, the CNC die-cutting machine works by using a pre-made precision die and then punching through the pressure of the equipment. It is very suitable for mass production of single shapes, forming them in one stamping with neat edges. However, it cannot identify and detect defects on the surface of the cut leather and remove leather with defects. Usually, manual inspection of the surface of the stamped and cut leather is required, which is inefficient. Utility Model Content

A second connecting plate frame 1104 is fixedly connected to the lower end of the second electric telescopic rod 1103.

[0028] The second electric telescopic rod 1103 pushes the second connecting plate frame 1104 to adjust, and the third vacuum suction cup mechanism 1106 adsorbs the whole piece of leather. Under the action of the fifth motor 1101 and the fourth rotating shaft, the third rotating frame 1102 is driven to rotate and place the leather on the corresponding die-cutting base 6.

[0029] A float adjustment assembly 15 is provided between the second connecting plate frame 1104 and the third mounting frame 1105, between the third connecting plate frame and the first mounting frame 1307, and between the first connecting plate frame 1404 and the second mounting frame 1405. A first vacuum suction cup structure 1308 is fixedly provided at the lower end of the first mounting frame 1307, a third vacuum suction cup mechanism 1106 is fixedly provided at the lower end of the third mounting frame 1105, and a second vacuum suction cup mechanism 1406 is fixedly provided at the lower end of the second mounting frame 1405. The float adjustment assembly 15 includes a first limiting bracket 1501, a second limiting bracket 1502 is provided below the first limiting bracket 1501, and a spring 1503 is fixedly connected between the second limiting bracket 1502 and the first limiting bracket 1501.

[0030] The first limiting bracket 1501 is fixedly connected to the second connecting plate bracket 1104 and the third connecting plate bracket 1404, respectively. The second limiting bracket 1502 is fixedly connected to the third mounting bracket 1105 and the first mounting bracket 1307 and the second mounting bracket 1405, respectively. Under the action of the spring 1503, when the second connecting plate bracket 1104, the third connecting plate bracket and the first connecting plate bracket 1404 are pushed by the corresponding telescopic structure, the corresponding vacuum suction cup mechanism comes into contact with the leather surface. Once part of the suction cup contacts the leather surface, it will be resisted by the spring 1503, and the telescopic mechanism will continue to... Continuing to move a short distance, overcoming the pressure of spring 1503, the suction cups that have reached higher points will be pressed down first, while the suction cups that have not yet made contact will continue to move downwards under the push of the spring until they also contact the leather, adapting to the uneven surface of the leather and ensuring that all suction cups can find their contact points. Furthermore, to ensure this process is effective, the following key parameters must be calculated and selected: The spring needs to be sufficiently "soft" so that it can be fully compressed within the limited downward distance of the extension adjustment, thus not hindering the continued descent of other suction cups; the required vacuum suction force F_vacuum is known. The spring preload F_initial and stiffness k must be designed such that: the total force F_initial + kx provided at the maximum compression stroke must be less than the vacuum suction force, otherwise the suction cups will be unable to effectively suck air due to excessive compression or will be bounced off; and it must be greater than the expected maximum height difference Δh between the peaks and troughs of the leather surface. That is, S > Δh. This is a prerequisite for ensuring that the lowest point also makes contact, and the distance that needs to be continued downwards after the first suction cup makes contact. This distance must be greater than Δh to ensure that the suction cup at the lowest point has enough time to descend to the contact surface. After the vacuum generator starts, the system monitors the vacuum level in the pipeline. If all suction cups are well sealed, the vacuum level will rise rapidly and reach a preset stable threshold. If a suction cup is not in contact and has a large leak, the vacuum level will not be able to reach this threshold, or the rising speed will be very slow. At this time, the system will determine "pickup failure" and trigger an alarm or retry process. The entire process is controlled by a PLC system. This system technology is existing technology. The second vacuum suction cup mechanism 1406 in the unloading adjustment frame 14 consists of multiple small vacuum suction cup modules. The system consists of a vacuum suction cup module corresponding to a cut piece of leather. Each module is connected to a vacuum generator via an independent pipe with a valve. After the leather is removed during the first detection, the corresponding valve on the vacuum suction cup module closes, meaning the vacuum suction cup does not need to work. Similarly, when leather is detected to be removed a second time, the vacuum suction cup on the second removal rack moves to the underside of the leather to adsorb it. Then, the valve on the corresponding vacuum suction cup module closes, meaning the module loses its adsorption force. The leather is then adsorbed and transferred by the vacuum suction cup on the second removal rack.

[0031] The die-cutting frame 12 includes a first hydraulic telescopic rod 1201 fixedly disposed through the upper end of the die-cutting frame 12. The lower end of the first hydraulic telescopic rod 1201 is fixedly connected to a die-cutting blade holder 1202. A second hydraulic telescopic rod 1203 is fixedly disposed through the upper end of the die-cutting frame 12. The lower end of the second hydraulic telescopic rod 1203 is fixedly connected to a fixed ear plate 1204. The fixed ear plate 1204 is fixedly connected to the left and right sides of the pressure frame 1205 respectively. The pressure frame 1205 is disposed outside the die-cutting blade holder 1202.

[0032] The second hydraulic telescopic rod 1203 pushes the fixed ear plate 1204, so that the pressure frame 1205 presses and fixes the leather periphery, and the first hydraulic telescopic rod 1201 pushes the die-cutting knife holder 1202 to die-cut the leather.

[0033] Combination Figures 1-8 The specific operation of a cutting machine for processing automotive leather interior trim according to this embodiment is as follows: The second electric telescopic rod 1103 pushes the second connecting plate frame 1104 for adjustment, and the third vacuum suction cup mechanism 1106 adsorbs the whole piece of leather. Under the action of the fifth motor 1101 and the fourth rotating shaft, the third rotating frame 1102 is driven to rotate, placing the leather on the corresponding die-cutting base 6. The first motor 4, the first rotating shaft, the meshing gear set 3 and the transmission shaft 2 drive the turntable 5 to rotate, which helps with continuous processing of leather loading, die-cutting, preliminary defect detection and removal and unloading. The turntable 5 is stably slidable and adjusted on the annular slide rail 10 through the slide 9. The second hydraulic telescopic rod 1203 pushes the fixed ear plate 1204, so that the pressure frame 1205 presses and fixes the leather periphery. Under the action of the first hydraulic telescopic rod 1201, the die-cutting blade holder 1202 is pushed to die-cut the leather. An industrial camera 8, under the action of a vision inspection system, detects defects on the upper surface of the leather. The second motor 1301 and the second rotating shaft drive the first rotating frame 1302 to rotate and adjust its position. Under the action of the third motor 1309 and the lead screw 1304, the moving frame 1305 moves on the lead screw 1304 and is adjusted to be above the defect. The third electric telescopic rod pushes the third connecting plate frame, so that the first vacuum suction cup mechanism 1308 adsorbs the defective leather and removes it. The first electric telescopic rod 1403 pushes the first connecting plate frame 1404 to adsorb the cut leather under the action of the second vacuum suction cup mechanism 1406. Under the action of the fourth motor 1401, the second rotating frame 1402 is rotated through the third rotating shaft, and the leather is rotated to the left side. The second industrial camera 1407 detects defects on the lower surface of the leather. After the leather is qualified, it is rotated and transferred to the front or rear side for unloading.
