Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and in particular to a feeding device for a laser cutting machine. Background Technology

[0002] Laser cutting uses a laser beam instead of a traditional mechanical blade, offering advantages such as high precision, fast cutting speed, no limitation on cutting patterns, automatic layout for material saving, smooth cuts, and low processing costs. The mechanical parts of the laser head do not contact the workpiece, preventing scratches on the workpiece surface during operation. Laser cutting is fast, producing smooth and flat cuts that generally require no further processing. It also features a small heat-affected zone, minimal sheet deformation, and narrow kerf. The cut is free of mechanical stress and shear burrs. It can process any planar shape and can cut large sheets without the need for molds.

[0003] In current metal sheet processing, the sheet is placed on the cutting bed of a laser cutting machine for cutting. However, the sheet is heavy and requires auxiliary equipment for loading, often an electric chuck. However, when using an overhead crane for lifting, the electric chuck sways significantly during the lifting process, easily colliding with the laser cutting equipment. This causes the sheet to vibrate, affecting cutting accuracy and posing a risk of it falling. Furthermore, when the electric chuck lowers the sheet, the residual suction force inside the chuck pulls the sheet upwards a certain distance before it detaches, potentially damaging it. The sheet may be dented by the cutting bed's teeth, affecting its appearance. Additionally, the falling sheet can impact the cutting bed, affecting the cutting equipment. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems existing in the above or prior art, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a feeding device for a laser cutting machine.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A feeding device for a laser cutting machine includes a support assembly and a feeding assembly. The support assembly includes a base, a bracket, and a crossbeam. The bracket is bolted to the upper side wall of the base. A first sliding member is slidably installed in the middle of the bracket. One end of the crossbeam is bolted to the side wall of the first sliding member.

[0009] The feeding assembly includes a motor and an electric suction cup. A second sliding member is slidably installed on the side wall of the crossbeam. The electric suction cup is fixedly installed on the lower side of the second sliding member. The motor is bolted to the middle of the bracket. A lead screw is fixedly connected to the motor spindle end. The lead screw is threaded to the center of the first sliding member, and the top of the lead screw is connected to the upper end of the bracket through a bearing.

[0010] As a preferred embodiment of the feeding device for the laser cutting machine of this utility model, a first electric push rod is bolted to the middle position of the crossbeam, and the end of the main shaft of the first electric push rod is bolted to the second sliding member.

[0011] As a preferred embodiment of the feeding device for the laser cutting machine of this utility model, the second sliding member has a second electric push rod connected to its outer side wall by bolts, and the main shaft end of the second electric push rod is located in the middle of the electric suction cup.

[0012] As a preferred embodiment of the feeding device for the laser cutting machine of this utility model, the second electric push rod spindle end is threadedly connected to a push rod, and a rubber pad is fixedly installed at the end of the push rod.

[0013] As a preferred embodiment of the feeding device for the laser cutting machine of this utility model, a reversing switch is snapped onto one side of the bracket, and the reversing switch is electrically connected to the motor through a wire.

[0014] As a preferred embodiment of the feeding device for the laser cutting machine of this utility model, a connecting rod is inserted into the side wall of the base, and the end of the connecting rod is provided with a stepped edge structure that matches the side wall of the base.

[0030] Example 1

[0031] Reference Figure 1-5 This is the first embodiment of the present utility model. This embodiment provides a support component 100 for a feeding device for a laser cutting machine. The support component 100 includes a base 101, a bracket 102 and a crossbeam 103. The bracket 102 is bolted to the upper side wall of the base 101. A first sliding member 104 is slidably installed in the middle of the bracket 102. One end of the crossbeam 103 is bolted to the side wall of the first sliding member 104.

[0032] Specifically, a connecting rod 106 is inserted into the side wall of the base 101, and the end of the connecting rod 106 has a stepped edge structure that matches the side wall of the base 101.

[0033] Furthermore, a handle bolt 107 is threadedly connected to the outer wall of the base 101, and the end of the handle bolt 107 penetrates the side wall of the base 101 and contacts the connecting rod 106.

[0034] When storing materials that need to be cut, loosen the handle bolt 107 on the side wall of the base 101, adjust the extension distance of the connecting rod 106 along the side wall of the base 101 so that the combined length of the side wall of the base 101 and the connecting rod 106 can accommodate the placement of materials. Then tighten the handle bolt 107, which, with the cooperation of the base 101, locks the connecting rod 106 to prevent it from loosening. The bracket 102 and the crossbeam 103 are used to install the feeding assembly 200. When in use, along the bracket 102, with the cooperation of the first sliding member 104, adjust the height of the crossbeam 103 to facilitate the feeding assembly 200 to pick up materials from above the base 101.

[0035] In summary, this application adds a support assembly 100 consisting of a base 101, a bracket 102, and a crossbeam 103 for storing materials. Adjusting the position of the connecting rod 106 along the base 101 can accommodate materials of different specifications for support and storage. The adjustment is simple and facilitates material docking and feeding with the laser cutting machine. At the same time, the crossbeam 103 connected by the first sliding member 104 is installed on the bracket 102, and the height of the crossbeam 103 can be adjusted along the bracket 102 to accommodate the feeding assembly 200 picking up materials from above the base 101 and transferring the materials to the feeding area of ​​the laser cutting machine. This facilitates the adjustment of the feeding assembly 200 and further facilitates material retrieval.

[0036] Example 2

[0037] Reference Figure 1-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a feeding component 200 for a feeding device for a laser cutting machine. The feeding component 200 includes a motor 201 and an electric suction cup 202. A second sliding member 105 is slidably installed on the side wall of the crossbeam 103. The electric suction cup 202 is fixedly installed on the lower side of the second sliding member 105. The motor 201 is bolted to the middle of the bracket 102. A lead screw 203 is fixedly connected to the main shaft end of the motor 201. The lead screw 203 is threaded to the center of the first sliding member 104, and the top of the lead screw 203 is connected to the upper end of the bracket 102 through a bearing.

[0038] Specifically, a first electric push rod 204 is bolted to the middle position of the crossbeam 103, and the end of the main shaft of the first electric push rod 204 is bolted to the second sliding member 105.

[0039] Furthermore, the outer wall of the second sliding member 105 is bolted to a second electric push rod 205, and the main shaft end of the second electric push rod 205 is located in the middle of the electric suction cup 202.

[0040] Furthermore, the second electric push rod 205 has a push rod 206 threadedly connected to the spindle end, and a rubber pad 207 is fixedly installed at the end of the push rod 206.

[0041] Preferably, a reversing switch 208 is snapped onto one side of the bracket 102, and the reversing switch 208 is electrically connected to the motor 201 via a wire.

[0042] In use, the power to the motor 201 is turned on via the reversing switch 208. When the motor 201 rotates forward, it drives the lead screw 203 to rotate. Since the side wall of the first sliding member 104 is in contact with the bracket 102, the first sliding member 104 cannot rotate on its own. Therefore, it will rise along the bracket 102 as the lead screw 203 rotates, thereby driving the crossbeam 103 to rise. Conversely, it will descend, lowering the height of the crossbeam 103, so that the electric suction cup 202 installed below the crossbeam 103 can align with the material surface. Then, the power to the electric suction cup 202 is turned on, allowing the electric suction cup 202 to pick up the material. Then, the motor 201 controls the crossbeam 103 to rise, driving the material to rise. After rising a certain distance, the power to the first electric push rod 204 is turned on. The first electric push rod 204, based on the connection of the crossbeam 103, pushes... The second sliding member 105 moves forward, moving the electric suction cup 202 with the material adsorbed to the feeding area of ​​the laser cutting machine. Then, the motor 201 is controlled to reverse, causing the crossbeam 103 to descend. The material is placed on the feeding mechanism of the laser cutting machine through the electric suction cup 202. Then, the power supply of the second electric push rod 205 is turned on. The second electric push rod 205 drives the rubber pad 207 to press down on the material surface on the connection base of the crossbeam 103 through the top rod 206. At this time, the power supply of the electric suction cup 202 is turned off, and the crossbeam 103 is controlled to rise. At this time, the electric suction cup 202 no longer adsorbs the material. The second electric push rod 205 continues to press down on the material surface to prevent the material from being adsorbed and lifted by the residual negative pressure of the electric suction cup 202. Then, the first electric push rod 204 and the second electric push rod 205 are controlled to retract, completing the feeding operation.

[0043] In summary, this application, by adding a movable crossbeam 103 assembly, allows for adjustment of the height of the crossbeam 103 by adjusting the position of the first sliding member 104 along the side wall of the bracket 102. During the lowering of the sheet material, the top rod 206, equipped with a rubber pad 207, is positioned above the crossbeam 103, facilitating the adjustment of the position of the electric suction cup 202 assembly and pressing the sheet material. This prevents the sheet material from being sucked up by the residual suction of the electric suction cup 202 during its detachment, thus avoiding collisions between the sheet material and the cutting bed due to force. This protects the sheet material, maintains its stability above the cutting bed, facilitates docking with the laser cutting machine, and reduces the impact of sheet material feeding on the laser cutting machine.
