Description

Technical Field

[0001] The present invention belongs to the technical field of punching equipment, and particularly relates to an automatic punching device for mesh doors. Background Art

[0002] A mesh door is a door with mesh holes, generally made of high-quality cold-rolled steel plates, having high strength and good durability. It is usually used in the front or rear of various equipment cabinets, network cabinets, etc., playing roles such as ventilation and heat dissipation, dust prevention, and observing the operating state of equipment. This is particularly important for some temperature-sensitive equipment. It can also effectively prevent dust and insects from entering the interior of the equipment cabinet, protecting the cleanliness and safety of the equipment. Users can directly observe the operating state of the equipment. Therefore, mesh doors are widely used in the communication and power industries. An automatic punching device for mesh doors is a device used to automatically punch holes in mesh doors. It can automatically send the mesh door material to the punching position and can use an advanced positioning system to automatically complete the punching action according to preset programs and parameters.

[0003] The existing punching of mesh doors uses manual loading and unloading, which is only achieved by moving in the X and Y axes. It has extremely high requirements for the accuracy and repeatability of the positioning system. It is very difficult to ensure that the position of the mesh door material is accurate and error-free every time during loading, which may lead to deviation in the punching position. And it requires that the edge distance of the mesh door is not less than one hundred millimeters, otherwise the production of the mesh door cannot be achieved, which may cause the sheet material to move or deform during the punching process, affecting the punching quality. At the same time, the production efficiency of the automatic punching device is restricted by the time of manual loading and unloading, and it also requires workers to perform a large amount of physical labor, which is likely to cause worker fatigue and injuries, increasing the labor cost and work injury risk of the enterprise.

[0004] Therefore, there is an urgent need to provide an automatic punching device for mesh doors to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned shortcomings of the prior art and provide an automatic punching device for mesh doors.

[0006] The technical solution adopted to solve the above technical problem is: an automatic punching device for mesh doors, including a mesh door punching press. A balance table is fixedly installed on one side of the mesh door punching press. A zeroing table is fixedly installed on one side of the balance table. Protective wire frames are fixedly installed on both sides of the balance table and the zeroing table. A positioning mechanism is arranged at the top end of the protective wire frame. A grasping mechanism is arranged at the bottom end of the positioning mechanism. A clamping mechanism is arranged at the bottom end of the grasping mechanism.

[0007] Through the above technical solution, the protective grid provides safety protection for the mechanism area of the mesh door punching machine. The zero-point table is used to accurately align the sheet material, the balance table is used to stably place the mesh door, and the mesh door punching machine is used to produce meshes with very small or special borderless margins on the mesh door.

[0008] Preferably, the positioning mechanism includes a vertical movement slide rail fixed to the top of the protective grid. A cross beam slide rail is slidably installed outside the vertical movement slide rail. Translation racks are fixedly installed on both the top of the protective grid and one side of the cross beam slide rail.

[0009] Through the above technical solution, the cross beam slide rail moves through the vertical movement slide rail.

[0010] Preferably, a vertical movement module is fixedly installed on one side of the cross beam slide rail. The outer surface of the gear of the vertical movement module meshes with one side of the translation rack. A horizontal movement module is fixedly installed on the other side of the cross beam slide rail. The outer surface of the gear of the horizontal movement module meshes with one side of the translation rack. A lifting module is slidably installed on one side of the horizontal movement module. The outer surface of the gear of the lifting module meshes with one side of the lifting module rack.

[0011] Through the above technical solution, the vertical movement module drives the cross beam slide rail to move through the vertical movement slide rail by means of the translation rack. The horizontal movement module drives itself to move through the cross beam slide rail by means of the translation rack. The lifting module drives itself to lift through the horizontal movement module by means of the rack, so as to accurately position and move the grabbed sheet material.

[0012] Preferably, a first electric limit block is fixedly installed at the bottom end of the zero-point table, and a second electric limit block is fixedly installed at the bottom end of the zero-point table. A limit groove is opened inside the zero-point table. Limit blocks are fixedly installed at one ends of the piston rods of the first electric limit block and the second electric limit block. The outer part of the limit block is slidably connected with the inner part of the limit groove.

[0013] Through the above technical solution, the zero-point table drives the limit blocks to move respectively through the first electric limit block and the second electric limit block, and then accurately aligns the sheet material on the zero-point table through the two limit blocks.

[0014] Preferably, the grabbing mechanism includes a grabbing mounting plate fixed to the bottom end of the lifting module. An adjustable stroke cylinder is fixedly installed at the top end of the grabbing mounting plate. A mesh door suction cup is fixedly installed at one end of the piston rod of the adjustable stroke cylinder.

[0015] Through the above technical solution, the lifting module drives the grabbing mounting plate to perform accurate positioning and movement, and the adjustable stroke cylinder drives the mesh door suction cup to adsorb the sheet material.

[0016] Preferably, a standard cylinder is fixedly installed at the top end of the grasping and mounting plate, and a mesh door electromagnet is fixedly installed at one end of the piston rod of the standard cylinder.

[0017] Through the above technical solution, the standard cylinder drives the mesh door electromagnet to magnetically attract the plate, and fixes it in various ways to prevent the plate from falling off. At the same time, the plate can be moved horizontally to prevent precise alignment operations on the plate.

[0018] Preferably, the clamping mechanism includes a linear guide fixed to the bottom end of the grasping and mounting plate. An adjusting slider is slidably installed outside the linear guide. A position adjusting cylinder is fixedly installed at the bottom end of the grasping and mounting plate, and a mesh door gripper is fixedly installed at one end of the piston rod of the position adjusting cylinder.

[0019] Through the above technical solution, the position adjusting cylinder drives the mesh door gripper to move, and the mesh door gripper moves on the linear guide through the adjusting slider.

[0020] Preferably, the top end of the mesh door gripper is fixedly connected to the bottom end of the adjusting slider. A clamping control cylinder is fixedly installed at the bottom end of the mesh door gripper, and one end of the piston rod of the clamping control cylinder is rotatably connected to one side of the mesh door gripper.

[0021] Through the above technical solution, the clamping control cylinder drives the mesh door gripper to clamp the plate. When the mesh door punching machine punches the mesh door gripper, the mesh door gripper is loosened. The position adjusting cylinder drives the mesh door gripper to move, and the mesh door gripper shrinks and moves on the linear guide through the adjusting slider, while the other two mesh door grippers continue to be fixed, enabling the plate to be processed continuously.

[0022] The beneficial effects of the present invention are as follows:

[0023] (1) By providing a clamping mechanism in the present invention, the mesh door gripper is used to clamp the processed plate to ensure the stability of the plate during processing. When the position adjusting cylinder is close to the edge of the punching die of the mesh door punching machine, it drives the mesh door gripper to retract, effectively avoiding potential interference problems. While the position adjusting cylinder drives some grippers to retract to avoid the punching die, the other two mesh door grippers still remain in the clamped state, enabling the plate to continue to be processed, thus realizing a high-efficiency and interference-free continuous production process, and further realizing the production of mesh doors with very small or special borderless margins, improving the accuracy and diversity of products;

[0024] (2) The present invention is provided with a positioning mechanism and a grasping mechanism. The grasping mechanism is responsible for stably and reliably grasping the sheet material, while the positioning mechanism drives the grasping mechanism to move precisely. Through the first electric limit block and the second electric limit block of the zero-point workbench, precise zeroing operation of the sheet material can be achieved. After zeroing, the sheet material is grasped and sent to the mesh door punching machine for punching processing. Through program control, efficient and precise punching processing is realized, further improving the production efficiency and product quality. BRIEF DESCRIPTION OF THE DRAWINGS

The balance table 2 balances and places the mesh door. The mesh door punching machine 1 is used to produce mesh holes with very small or special borderless margins for the mesh door.

[0034] As Figures 1-4 shown, a positioning mechanism 5 is provided at the top end of the protective grid frame 4. The positioning mechanism 5 includes a vertical movement slide rail 501 fixed to the top end of the protective grid frame 4. A cross beam slide rail 502 is slidably installed outside the vertical movement slide rail 501. Translation racks 503 are fixedly installed at the top end of the protective grid frame 4 and on one side of the cross beam slide rail 502. A vertical movement module 504 is fixedly installed on one side of the cross beam slide rail 502. The outer surface of the gear of the vertical movement module 504 meshes with one side of the translation rack 503. A cross movement module 505 is fixedly installed on the other side of the cross beam slide rail 502. The outer surface of the gear of the cross movement module 505 meshes with one side of the translation rack 503. A lifting module 506 is slidably installed on one side of the cross movement module 505. The outer surface of the gear of the lifting module 506 meshes with one side of the rack of the lifting module 506. The vertical movement module 504 drives the cross beam slide rail 502 to move through the vertical movement slide rail 501 through the translation rack 503. The cross movement module 505 drives itself to move through the cross beam slide rail 502 through the translation rack 503. The lifting module 506 drives itself to lift through the cross movement module 505 through the rack, so as to accurately position and move the grabbed plate.

[0035] As Figure 5 and Figure 6As shown, a grasping mechanism 6 is provided at the bottom end of the positioning mechanism 5. The grasping mechanism 6 includes a grasping mounting plate 601 fixed to the bottom end of the lifting module 506. At the top end of the grasping mounting plate 601, an adjustable stroke cylinder 602 is fixedly installed. One end of the piston rod of the adjustable stroke cylinder 602 is fixedly installed with a mesh door suction cup 603. At the top end of the grasping mounting plate 601, a standard cylinder 604 is fixedly installed. One end of the piston rod of the standard cylinder 604 is fixedly installed with a mesh door electromagnet 605.

The adjustable stroke cylinder 602 drives the mesh door suction cup 603 to adsorb the plate, and the standard cylinder 604 drives the mesh door electromagnet 605 to magnetically attract the plate. Fixation is carried out in multiple ways to prevent the plate from falling off. At the same time, the plate can be moved horizontally to prevent precise zeroing operations on the plate.

[0036] As Figure 6 As shown, a clamping mechanism 7 is provided at the bottom end of the grasping mechanism 6. The clamping mechanism 7 includes a linear guide rail 701 fixed to the bottom end of the grasping mounting plate 601. An adjustment slider 702 is slidably installed outside the linear guide rail 701. At the bottom end of the grasping mounting plate 601, a position adjustment cylinder 703 is fixedly installed. One end of the piston rod of the position adjustment cylinder 703 is fixedly installed with a mesh door jaw 704. The top end of the mesh door jaw 704 is fixedly connected to the bottom end of the adjustment slider 702. At the bottom end of the mesh door jaw 704, a clamping control cylinder 705 is fixedly installed. One end of the piston rod of the clamping control cylinder 705 is rotatably connected to one side of the mesh door jaw 704. The clamping control cylinder 705 drives the mesh door jaw 704 to clamp the plate. When the mesh door punching machine 1 punches the mesh door jaw 704, the mesh door jaw 704 is released, and the position adjustment cylinder 703 drives the mesh door jaw 704 to move. The mesh door jaw 704 contracts and moves on the linear guide rail 701 through the adjustment slider 702, while the other two mesh door jaws 704 continue to be fixed, enabling the plate to be continuously processed.

[0037] The working principle of this embodiment is as follows. The protective grid 4 safeguards the mechanism area of the mesh door punching machine 1. The vertical movement module 504 drives the crossbeam slide rail 502 to move through the vertical movement slide rail 501 by means of the translation rack 503. The horizontal movement module 505 drives itself to move through the crossbeam slide rail 502 by means of the translation rack 503. The lifting module 506 drives itself to lift through the horizontal movement module 505 by means of the rack, thereby precisely positioning and moving the grabbed sheet material. The lifting module 506 drives the grabbing and mounting plate 601 to perform precise positioning and movement. The adjustable stroke cylinder 602 drives the mesh door suction cup 603 to adsorb the sheet material. The standard cylinder 604 drives the mesh door electromagnet 605 to magnetically attract the sheet material. After grabbing the sheet material in the material area, it is placed on the zeroing table 3. The first electric limit block 507 and the second electric limit block 508 can respectively drive the limit block to move, thereby realizing the precise zeroing operation of the sheet material located on the zeroing table 3 through the limit block. The position adjustment cylinder 703 drives the mesh door gripper 704 to move. The mesh door gripper 704 moves through the adjustment slider 702 on the linear guide rail 701. The clamping control cylinder 705 drives the mesh door gripper 704 to clamp and fix the sheet material. Then, the fixed sheet material after the zeroing operation is placed on the balance table 2. The mesh door punching machine 1 punches the sheet material. When the mesh door punching machine 1 punches the area of the mesh door gripper 704, this mesh door gripper 704 is released. The position adjustment cylinder 703 drives the mesh door gripper 704 to move. The mesh door gripper 704 contracts and moves through the adjustment slider 702 on the linear guide rail 701, while the other two mesh door grippers 704 continue to be fixed, enabling the sheet material to be continuously processed, and at the same time realizing the production of mesh doors with very small or special borderless margins. Similarly, the punched mesh door is moved to the semi-finished product area for the next processing. After grabbing a new sheet material, it is placed on the zeroing table 3, and this process is repeated.

[0038] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
