Description

Technical Field

[0001] The utility model belongs to the field of automated production equipment, in particular to an automatic feeding system for a laser cutting machine with convenient on-site positioning and debugging. Background Art

[0002] Laser cutting uses a focused, high-energy-density laser beam to instantly heat the material until it melts or burns, then uses a high-speed airflow to blow away the molten material, achieving precise cutting. Its high precision and flexibility have made it a key technology in numerous industries. Laser cutting technology is particularly well-suited for processing metal materials. The use of laser cutting machines on automated production lines has significantly improved production efficiency and processing accuracy, particularly in sheet metal processing. However, manual handling of sheet metal plates ranging in size from 1.5 m x 2.0 m to 2.0 m x 3.0 m does present challenges. The weight and size of these materials make manual handling both laborious and inefficient, especially when handling thicker sheets, which can be nearly impossible to accomplish manually. To address this issue, automated handling equipment, such as robotic arms or specialized handling robots, is often employed to improve handling efficiency and safety, ensuring a smooth production process.

[0003] The existing technology also has the following deficiencies:

[0004] 1. Existing laser cutting machines rely on manual labor to carry metal plates, which is laborious and inefficient. When the material thickness is large, manual handling is almost impossible, which greatly reduces the operating efficiency of the laser cutting machine.

[0005] 2. In addition, the on-site positioning and debugging of existing laser cutting machines are complicated and require high technical requirements. The positioning of the target position is not fast and accurate enough, and the position adjustment also requires a lot of time and effort. Utility Model Content

[0006] In order to overcome the above-mentioned defects, the utility model provides an automatic feeding system for a laser cutting machine with convenient on-site positioning and debugging, which solves the problem that the existing laser cutting machine relies on manual handling and the adjustment of the handling target position is complex and inefficient.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic loading system for a laser cutting machine with convenient on-site positioning and debugging, including an automatic loading system, wherein the automatic loading system includes a control terminal, a user terminal, an execution module and a braking unit. The control terminal is the electrical infrastructure of the entire system, which receives various external input signals and sends various output signals for external control. The user terminal is a movable, simple and convenient external signal input controller for the operator to use. The execution module includes a servo module, a suction cup transport device and various photoelectric sensors.

[0008] As a further solution of the present invention: the suction cup transporting device includes a gantry, a slide rail and a telescopic suction cup, the pulleys at the bottom of both sides of the gantry are slidably connected to the slide rail on the corresponding side, the telescopic suction cup is mounted on the crossbeam of the gantry, and the telescopic suction cup is slidably connected to the crossbeam of the gantry. Under the logical control of the control terminal, the suction cup transporting device can complete the suction and release of the raw material metal plate, and a working platform is provided under the suction cup transporting device.

[0009] As a further solution of the present invention: the working platform includes a gantry suspension, a support frame, a laser cutting machine platform and a raw material stacking platform. The two sides of the gantry suspension are fixedly connected to the support frame on the corresponding side, the left side of the bottom of the gantry suspension is fixedly connected to the laser cutting machine platform, and the right side of the bottom of the gantry suspension is fixedly connected to the raw material stacking platform.

[0010] As a further solution of the present invention: four working positions are set on the upper surface of the gantry suspension, which are the left extreme working position, the transport target position, the initial working position and the right extreme working position from left to right. A detachable magnetic proximity switch is arranged on the top of the transport target position, and each photoelectric sensor is used to obtain the signal of each working position for the control terminal to perform logical judgment and control.

[0011] As a further solution of the present invention: the servo module is controlled by the internal program of the automatic feeding system, and the servo drives the suction cup handling device to move, thereby realizing the handling of the raw material metal plate and accurately positioning to complete the automatic feeding operation of the laser cutting machine.

[0012] As a further solution of the present invention: when the braking unit encounters an unexpected failure, the automatic braking unit or the manual braking unit can promptly control the automatic feeding system to stop running, thereby protecting the safety of the system itself and the equipment operator.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This equipment solves the problem of automatic loading of laser cutting machines. It does not require manpower to load the board. It is efficient in actual production and can realize automatic loading.

[0015] 2. A special magnetic proximity switch is arranged above the transport target position. When this switch is triggered, the system will know that the suction cup transport device of this equipment has moved to the transport target position, thereby ensuring the accuracy of the transport target position. The automatic loading system has been programmed internally and does not require on-site personnel to perform programming and debugging. It only needs to install the magnetic proximity switch above the target position, which is convenient for on-site personnel to debug and install on-site. When manually transporting the tablet, the operation indicator light of the proximity switch can also be used to confirm whether the tablet is transported in place. If the transport position needs to be changed, it is only necessary to change the installation position of the magnetic switch, which greatly saves on-site workload.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 3 As shown, the utility model provides a technical solution:

[0022] Automatic loading system, which includes a control terminal, a user terminal, an execution module and a brake unit. The control terminal is the electrical infrastructure of the entire system, receiving various external input signals and issuing various output signals for external control. The user terminal is a movable, simple and convenient external signal input controller for the operator to use. The execution module includes a servo module, a suction cup handling device and various photoelectric sensors.

[0023] The suction cup handling device includes a gantry 1, a slide rail 2, and a telescopic suction cup 3. The pulleys at the bottom of both sides of the gantry 1 are slidably connected to the slide rail 2 on the corresponding side. The telescopic suction cup 3 is sleeved on the crossbeam of the gantry 1 and is slidably connected to the crossbeam of the gantry 1. Under the logical control of the control terminal, the suction cup handling device can complete the suction and release of the raw material metal plate. A working platform is provided under the suction cup handling device.

[0024] Specifically, the suction cup handling device can move forward and backward by sliding the gantry 1 in the slide rail 2, thereby moving to the target position, and the telescopic suction cup 3 can absorb and release the metal raw material flat plate and move it up and down;

[0025] The working platform includes a gantry suspension 4, a support frame 5, a laser cutting machine platform 6 and a raw material stacking platform 7. Both sides of the gantry suspension 4 are fixedly connected to the support frame 5 on the corresponding side. The left side of the bottom of the gantry suspension 4 is fixedly connected to the laser cutting machine platform 6, and the right side of the bottom of the gantry suspension 4 is fixedly connected to the raw material stacking platform 7.

[0026] The upper surface of the gantry suspension 4 is provided with four working positions, which are, from left to right, the left limit working position 8, the transport target position 9, the initial working position 10 and the right limit working position 11. A detachable magnetic proximity switch 12 is arranged on the top of the transport target position 9. Each photoelectric sensor is used to obtain the signal of each working position for the control terminal to perform logical judgment and control.

[0027] The servo module is controlled by the internal program of the automatic loading system. The servo drives the suction cup handling device to move, realize the handling of raw material metal plates, and accurately locate and complete the automatic loading operation of the laser cutting machine. The braking unit, when encountering an unexpected fault, the automatic braking unit or the manual braking unit can promptly control the automatic loading system to stop running, protecting the safety of the system itself and the equipment operator;

[0028] Specifically, the suction cup transporting device maintains an upward state to the upper end of the system design, and then runs on the crossbeam of the gantry 1 to above the raw material stacking platform 7. The suction cup transporting device descends until it reaches the raw material stacking platform 7. The air compressor is started, so that the telescopic suction cup 3 enters a vacuum state to suck the flat plate to be transported. The suction cup transporting device maintains a vacuum state, ascends to the upper end for transporting, and transports the metal raw material flat plate from above the raw material stacking platform 7 to above the laser cutting machine platform 6 and then descends until the metal flat plate is placed on the laser cutting machine platform 6. The air compressor is turned off, and air enters the pipeline to release the vacuum state of the telescopic suction cup 3. During the upward movement of the telescopic suction cup 3, the suction cup transporting device detaches from the metal raw material flat plate. After ascending to the highest point, the suction cup transporting device moves to above the raw material stacking platform 7, waiting for the next transport command. The transport target position can be set by a separate magnetic proximity switch 12.

[0029] The working principle of this utility model is:

[0030] The suction cup handling device can move forward and backward by sliding the gantry 1 in the slide rail 2, thereby moving to the target position. The telescopic suction cup 3 can absorb and release the metal raw material flat plate and move it up and down.

[0031] The suction cup transporting device remains in an upward state to the upper end of the system design, and then runs on the crossbeam of the gantry 1 to above the raw material stacking platform 7. The suction cup transporting device descends until it reaches the raw material stacking platform 7. The air compressor is started to put the telescopic suction cup 3 into a vacuum state to suck the flat plate to be transported. The suction cup transporting device maintains a vacuum state and ascends to the upper end for transporting. The metal raw material flat plate is transported from above the raw material stacking platform 7 to above the laser cutting machine platform 6 and then descends until the metal flat plate is placed on the laser cutting machine platform 6. The air compressor is turned off, and air enters the pipeline to release the vacuum state of the telescopic suction cup 3. During the upward movement of the telescopic suction cup 3, the suction cup transporting device detaches from the metal raw material flat plate. After ascending to the highest point, the suction cup transporting device moves to above the raw material stacking platform 7, waiting for the next transport command. The transport target position can be set by a separate magnetic proximity switch 12.

[0032] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of this patent.
