Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a sheet metal feeding device. Background Technology

[0002] Laser cutting machines are commonly used in sheet metal processing, primarily for cutting metal sheets. During operation, the metal sheet is placed on the laser cutting machine's worktable for processing. After processing, the finished sheet needs to be removed and replaced. Existing technology uses suction cup loading devices in conjunction with lifting equipment such as gantry cranes to hoist the sheet onto the worktable. However, due to the varying sizes and shapes of the sheets, the suction cup position frequently needs adjustment. For example, patent document CN214815898U discloses a laser cutting loading device including a suction cup, a rectangular mounting frame, and multiple connecting mechanisms mounted on the mounting frame. The connecting mechanisms include mounting blocks that slide laterally along the mounting frame and locking components that secure the mounting blocks and the mounting frame. The suction cup is mounted on the mounting block, and its position can be adjusted according to the size of the sheet. The solution has the following problems: the mounting block is installed on the crossbar by fastening bolts. When adjusting the position of the mounting block, it is necessary to manually loosen the fastening bolts, slide the mounting block to the appropriate position, and then tighten the fastening bolts. The operation is relatively complicated, the adjustment efficiency is low, and frequent tightening of bolts can easily damage the threads. Utility Model Content

[0003] To address the shortcomings of existing technologies, the present invention provides a sheet material feeding device that solves the problem of low efficiency in adjusting the suction cup position of existing feeding devices.

[0004] To solve the above problems, the technical solution adopted by this utility model is: a plate feeding device, including a long rod, a cross rod, a longitudinal mounting block, a transverse mounting block, a first rack, a second rack, and a motor. The long rod is horizontally arranged, the longitudinal mounting block is slidably mounted on the long rod, the middle part of the cross rod is bolted to the lower part of the longitudinal mounting block so that the cross rod is perpendicular to the long rod in the horizontal direction, the transverse mounting block is slidably mounted on the cross rod, and a suction cup is provided on the transverse mounting block. The bottom of the long rod is provided with a first rack along the length direction, the longitudinal mounting block is provided with a motor, and the output shaft of the motor is provided with a gear that meshes with the first rack. The bottom of the cross rod is provided with a second rack along the length direction, the transverse mounting block is provided with a motor, the output shaft of the motor is provided with a gear that meshes with the second rack, and the motor is provided with an electromagnetic brake.

[0005] The beneficial effects of this solution are as follows: Compared with the prior art, the plate feeding device of this utility model has a longitudinal mounting block on a long rod, a crossbar on the longitudinal mounting block, a transverse mounting block on the crossbar, a suction cup on the transverse mounting block, a rack at the bottom of the long rod and the crossbar, a motor on the longitudinal mounting block and the transverse mounting block, and a gear on the output shaft of the motor that meshes with the rack. When the motor works, it drives the gear to rotate, which in turn drives the crossbar to move along the direction of the long rod, and the transverse mounting block to slide along the crossbar. The position of the suction cup can be adjusted to accommodate plates of various sizes. This adjustment process does not require manual tightening of bolts and has high adjustment efficiency.

[0006] Furthermore, the first rack is embedded in the long rod, with the tooth tip not protruding from the lower end face of the long rod, and the second rack is embedded in the crossbar, with the tooth tip not protruding from the lower end face of the crossbar, ensuring smooth sliding of the longitudinal mounting block and the transverse mounting block.

[0007] Furthermore, the long rod is provided with a vertically upward lifting rod in the middle, which is used to connect lifting equipment such as gantry cranes when hoisting and loading devices.

[0008] Furthermore, tie rods are provided at both ends of the long rod and between them and the hanging rod, forming a triangular structure to improve the structural stability of the device.

[0009] Furthermore, the motor is a stepper motor, and the motor start and stop are controlled by a PLC, which can accurately control the motor's running stroke and the position of the suction cup.

[0010] Furthermore, multiple longitudinal mounting blocks are arranged on both sides of the long rod. The number of longitudinal mounting blocks can be determined according to the number of crossbars to ensure the stability of the plate during hoisting. Attached Figure Description

The long rod 1 is horizontally arranged. The longitudinal mounting block 3 is slidably mounted on the long rod 1. The middle part of the horizontal rod 2 is bolted to the lower part of the longitudinal mounting block 3, making the horizontal rod 2 perpendicular to the long rod 1 in the horizontal direction. The transverse mounting block 4 is slidably mounted on the horizontal rod 2. The transverse mounting block 4 is provided with a suction cup 5. The bottom of the long rod 1 is provided with a first rack 6 along its length direction. The longitudinal mounting block 3 is provided with a first rack 6. The motor 8 has a gear on its output shaft that meshes with the first rack 6. The bottom of the crossbar 2 has a second rack 7 along its length. The transverse mounting block 4 has the motor 8, and the output shaft of the motor 8 has a gear that meshes with the second rack 7. When the motor 8 is working, it drives the transverse mounting block 4 to slide on the crossbar 2 and drives the longitudinal mounting block 3 to slide on the long rod 1 to adjust the position of the suction cup 5. It is suitable for hoisting plates of various sizes. The motor is equipped with an electromagnetic brake. When the motor is powered off, the electromagnetic brake locks the motor rotor to prevent it from rotating freely and maintains the position of the suction cup.

[0016] The first rack 6 is embedded in the long rod 1, with the tooth tip not protruding from the lower end face of the long rod 1. The second rack 7 is embedded in the crossbar 2, with the tooth tip not protruding from the lower end face of the crossbar 2, ensuring smooth sliding of the longitudinal mounting block 3 and the transverse mounting block 4. The long rod 1 has a vertically upward lifting rod 9 in the middle, which is used to connect gantry cranes and other lifting equipment when hoisting the material loading device. Tie rods 10 are provided between the two ends of the long rod 1 and the lifting rod 9, forming a triangular structure to improve the structural stability of the device. The motor 8 is a stepper motor 8, which is started and stopped by a PLC, and the running stroke of the motor 8 can be accurately controlled to accurately control the position of the suction cup 5. Multiple longitudinal mounting blocks 3 are set on both sides of the long rod 1, and the number of longitudinal mounting blocks 3 can be determined according to the number of crossbars 2 to ensure the stability of the plate during hoisting.

[0017] The specific implementation process is as follows:

[0018] When installing the feeding device, connect motor 8 to the PLC controller, and connect suction cup 5 to the vacuum pump via an air pipe. Connect the suction cup 5 to the hoisting rod 9 using the workshop's gantry crane. Based on the size of the material to be fed, control motor 8 to drive the longitudinal mounting block 3 to slide on the long rod 1, thereby moving the crossbar 2 to adjust the longitudinal position of suction cup 5. This causes the transverse mounting block 4 to slide on the crossbar 2, thereby adjusting the transverse position of suction cup 5. After the suction cup 5 is properly positioned, hoist the feeding device onto the upper surface of the material, ensuring that suction cup 5 is in close contact with the upper surface of the material. Start the vacuum pump to evacuate the suction cup 5. After suction cup 5 holds the material, hoist the material onto the worktable of the laser cutting machine using the gantry crane. The position of suction cup 5 is adjusted via motor 8 during the process. The operation is simple, requires no manual tightening of bolts, and has high adjustment efficiency.
