Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, specifically to a dual-station sheet metal feeding machine. Background Technology

[0002] In the sheet metal processing industry, traditional sheet metal feeding methods rely heavily on manual handling, which is not only labor-intensive and inefficient, but also prone to inaccurate sheet metal positioning due to human error, affecting the quality of subsequent processing. Furthermore, single-station feeding equipment suffers from long waiting times during continuous production, making it difficult to meet the demands of high-efficiency production. Therefore, developing a sheet metal feeding machine that enables simultaneous dual-station operation, has a high degree of automation, and provides precise positioning has become an urgent need in the industry.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] Please see Figures 1-7 The dual-station sheet metal feeding machine shown includes a gantry frame 1, an X-axis transverse movement assembly 2, a Y-axis transverse movement assembly 3, a Z-axis assembly 4, and a gripping assembly 5.

[0037] The X-axis lateral movement assembly 2 is located at the upper end of the gantry frame 1 and is the core driving component for realizing the movement of the entire equipment along the X-axis direction. It is used to drive the Y-axis lateral movement assembly 3 and other components connected to it to move precisely along the X-axis direction. It includes a bottom crossbeam 201 symmetrically arranged on the gantry frame 1, an X-axis motor 202, an X-axis motor base plate 203 rigidly connected to the gantry frame 1, an X-axis transmission rod 1 204, an X-axis transmission rod 205, a set of X-axis linear guide rail pairs 206, a set of synchronous belts 207, and a synchronous belt pressure plate 208 arranged on the synchronous belts 207. The bottom crossbeam 201 serves as the mounting base for the X-axis lateral movement assembly 2, providing stable support for other components. Its connection with the gantry frame 1 is fixed with high-strength bolts to ensure that no relative displacement occurs during equipment operation. Two sets of X-axis transmission rods 205 are provided, respectively connected at both ends of the bottom crossbeam 201 by bearings. High-precision deep groove ball bearings are used to ensure smooth and stable rotation of the X-axis transmission rods 205. One end of each of the two X-axis transmission rods 205 closest to the first X-axis transmission rod 204 is also connected to both ends of the first X-axis transmission rod 204 by couplings. Flexible couplings are used to effectively buffer impact forces during transmission and reduce equipment vibration. The X-axis motor 202 is mounted on the X-axis motor base plate 203, which is rigidly connected to the gantry frame 1 by welding, providing a stable mounting platform for the X-axis motor 202. Its shaft is connected to the middle of the first X-axis transmission rod 204 via a synchronous belt 207 and a synchronous pulley. The synchronous belt 207 is a polyurethane synchronous belt, characterized by high transmission efficiency and low noise. Each of the X-axis transmission rods 205 is also provided with an X-axis synchronous pulley. The X-axis synchronous pulley is connected to the X-axis transmission rod 205 by a key to ensure the reliability of power transmission. Each of the two X-axis synchronous pulleys on the same bottom crossbeam 201 is provided with a synchronous belt 207. The two X-axis linear guide pairs 206 are respectively provided on the two bottom crossbeams 201. The guide rails of the X-axis linear guide pairs 206 are fixed to the bottom crossbeams 201 by bolts. The slider is used to connect with the Y-axis transverse component 3.

[0038] In the X-axis linkage, when the X-axis motor 202 starts, its output torque is transmitted to the X-axis transmission rod 204 through the synchronous belt 207, causing the X-axis transmission rod 204 to rotate. The X-axis transmission rod 204 transmits power to the two sets of X-axis transmission rods 205 through the couplings at both ends, causing the X-axis transmission rods 205 to rotate synchronously, which in turn drives the X-axis synchronous pulley to rotate. The rotation of the X-axis synchronous pulley causes the synchronous belt 207 to translate. The synchronous belt pressure plate 208 on the synchronous belt 207 then drives the Y-axis transverse component 3 connected to it to move linearly along the X-axis linear guide pair 206 in the X-axis direction, realizing the movement of the Y-axis transverse component 3 and related components in the X-axis direction.

[0039] The Y-axis transverse component 3 is located at the upper end of the X-axis transverse component 2 and is connected to the X-axis transverse component 2. It can move along the X-axis direction under the control of the X-axis transverse component 2, and also serves as a key component for driving the Z-axis component 4 to move along the Y-axis direction. It includes a Y-axis crossbeam 301, a Y-axis motor 302, a Y-axis motor base plate 303, a guide wheel 304, a set of Y-axis side connecting frames 305, a set of Y-axis linear guide pairs 306, a vertical connecting plate 307, a bottom support frame 308, a set of straight racks 309, a drive gear 310, a second Y-axis motor 311, a second Y-axis linear guide pair 312, a Y-axis synchronous belt 313, a Y-axis rotating shaft 314, a Y-axis synchronous pulley 315, and a Y-axis synchronous belt pressure plate 316. The Y-axis crossbeam 301, serving as the main structure of the Y-axis transverse component 3, is made of high-strength aluminum alloy, reducing its weight while ensuring structural strength. Its two ends are rigidly connected to the sliders on the two X-axis linear guide pairs 206 via bolt fastening. It is also fixedly connected to the two synchronous belt pressure plates 208 to ensure that the Y-axis crossbeam 301 moves synchronously with the synchronous belt 207. The Y-axis motor base plate 303 is fixedly mounted on the lower part of the housing of the Y-axis motor 302, providing an installation position for the guide wheels 304. The upper end of the Y-axis motor 302 is rigidly connected to the lower end face of the Y-axis crossbeam 301 via bolt fastening. Two guide wheels 304 are provided, mounted on both sides of the Y-axis motor base plate 303 via axle shafts. The guide wheels 304 can rotate freely around the shaft, guiding and limiting the spur rack 309. Two Y-axis side connecting brackets 305 are symmetrically fixed on both sides of the Y-axis crossbeam 301 and connected to the Y-axis crossbeam 301 by welding. Two Y-axis linear guide pairs 306 are respectively located on the sides of the two Y-axis side connecting brackets 305, and their sliders are connected to the vertical connecting plate 307. The guide rails of the Y-axis linear guide pairs 306 are fixed to the Y-axis side connecting brackets 305 by bolts. The lower end of each vertical connecting plate 307 is rigidly connected to a bottom support bracket 308 by welding. A Y-axis linear guide pair 306 is fixed on each of the two bottom support brackets 308 to further enhance the stability of the Z-axis assembly 4 in the Y-axis direction. The output shaft of the Y-axis motor 302 is provided with a drive gear 310 that meshes with both racks 309 simultaneously. The drive gear 310 is connected to the output shaft of the Y-axis motor 302 by a key. The two guide wheels 304 are respectively engaged with the back sides of the two racks 309 to prevent the racks 309 from deviating during movement.

[0040] The second Y-axis linear guide rail 312 is disposed on the lower end face of the Y-axis beam 301. Its guide rail is fixed to the Y-axis beam 301 by bolts, and its slider is fixedly connected to the Y-axis synchronous belt pressure plate 316, providing guidance for the movement of the Y-axis synchronous belt pressure plate 316. Two Y-axis rotating shafts 314 are provided, respectively disposed at both ends of the Y-axis beam 301 by bearings. High-precision rolling bearings are used to ensure the smooth rotation of the Y-axis rotating shafts 314. Two Y-axis synchronous pulleys 315 are provided, respectively disposed on the Y-axis rotating shafts 314, connected by a key to achieve power transmission, and simultaneously connected to the Y-axis synchronous belt 313. The Y-axis synchronous belt 313 is made of wear-resistant rubber to extend its service life. The second Y-axis motor 311 is fixedly disposed on the upper part of one end of the Y-axis beam 301, connected to the Y-axis beam 301 by bolts, and its rotating shaft is connected to one end of one of the Y-axis rotating shafts 314 via a synchronous belt and synchronous pulley, achieving power transmission. The Y-axis synchronous belt pressure plate 316 is fixedly mounted on the Y-axis synchronous belt 313 and is also fixedly connected to the upper end of the Y-axis motor 302 by bolt fastening, which serves to transmit power.

[0041] In the Y-axis direction, Y-axis motor 302 and Y-axis motor 311 move synchronously and complement each other, jointly driving the relevant components to move in the Y-axis direction. When it is necessary to drive the Z-axis assembly 4 to move in the Y-axis direction, Y-axis motor 302 and Y-axis motor 311 start simultaneously with consistent speed and direction. After the Y-axis motor 302 starts, its output shaft drives the drive gear 310 to rotate. Since the drive gear 310 meshes with two racks 309 at the same time, under the action of gear meshing transmission, the drive gear 310 will be displaced relative to the racks 309, thereby driving the Y-axis motor 302, the Y-axis motor base plate 303 and related components connected to it to move. At the same time, under the guiding and limiting action of the guide wheel 304 on the racks 309, the accuracy of the movement direction is ensured. The vertical connecting plate 307 is driven to move along the Y-axis direction by the Y-axis linear guide pair 306 on the Y-axis side connecting frame 305. The vertical connecting plate 307 then drives the bottom support frame 308 and the Z-axis assembly 4 connected to it to move synchronously along the Y-axis direction. Simultaneously, Y-axis motor 311 starts, and its output torque is transmitted to Y-axis shaft 314 via synchronous belt and synchronous pulley, causing Y-axis shaft 314 to rotate. Y-axis shaft 314 drives Y-axis synchronous pulley 315 to rotate, causing Y-axis synchronous belt 313 to translate. Y-axis synchronous belt 313 drives Y-axis synchronous belt pressure plate 316 to move linearly along Y-axis linear guide pair 312 in the Y-axis direction. Since Y-axis synchronous belt pressure plate 316 is connected to Y-axis motor 302, it drives Y-axis motor 302 and related components to move synchronously, further driving Z-axis assembly 4 to move in the Y-axis direction. The synchronous movement of both not only enhances the driving force and ensures the stability and smoothness of movement, but also allows the other motor to briefly assist in maintaining movement if one motor experiences a minor malfunction, improving the reliability of equipment operation.

[0042] Two Z-axis assemblies 4 are symmetrically arranged on both sides of the Y-axis transverse assembly 3. Under the control of the Y-axis transverse assembly 3, they move along the Y-axis direction to drive the gripping assembly 5 to move along the Z-axis direction, thus achieving the lifting and lowering action of the gripping assembly 5. Each Z-axis assembly 4 has a gripping assembly 5 at its lower end, which includes a Z-axis drive screw pair 401, a Z-axis motor 402, a Z-axis vertical beam 403, and a Z-axis linear guide pair 404. The Z-axis drive screw pair 401 is mounted on the Z-axis vertical beam 403, which provides mounting support for the Z-axis drive screw pair 401 and the Z-axis linear guide pair 404. The screw nut seat on the Z-axis drive screw pair 401 is rigidly connected to the vertical connecting plate 307 and fixed with bolts. The Z-axis motor 402 is fixedly mounted on the upper section of the Z-axis vertical beam 403. Its output shaft is connected to the lead screw on the Z-axis transmission lead screw pair 401 via a coupling. A rigid coupling is selected to ensure transmission accuracy. The guide rail on the Z-axis linear guide pair 404 is fixedly connected to the Z-axis vertical beam 403, and its slider is fixedly connected to the lead screw nut seat on the Z-axis transmission lead screw pair 401 to enhance the stability of the lead screw nut seat's movement.

[0043] In the Z-axis linkage, after the Z-axis motor 402 starts, its output torque is transmitted to the lead screw of the Z-axis transmission lead screw pair 401 through the coupling, causing the lead screw to rotate. Since the lead screw and the lead screw nut seat are connected by threads, the rotation of the lead screw is converted into the linear motion of the lead screw nut seat. During the movement of the lead screw nut seat, on the one hand, it drives the vertical connecting plate 307 and other components connected to it to move, and on the other hand, under the guidance of the Z-axis linear guide pair 404, it ensures the linearity of the motion trajectory, thereby realizing the lifting and lowering movement of the Z-axis vertical beam 403 and the gripping assembly 5 along the Z-axis direction.

[0044] The gripping component 5 is used to grip the sheet material and is a component that directly contacts the sheet material. It includes two side fixing plates 501, a suction cup fixing plate 502, a vacuum suction cup 503, a dust blowing nozzle 504, and a nozzle bracket 505. The suction cup fixing plate 502 is fixedly mounted on the lower end surface of the side fixing plate 501 and connected by bolts. The two side fixing plates 501 are symmetrically arranged on both sides of the lower end of the Z-axis vertical beam 403 and welded to the Z-axis vertical beam 403. The vacuum suction cup 503 is mounted on the suction cup fixing plate 502. The vacuum suction cup 503 is connected to an external vacuum generator via an air pipe and is used to adsorb the board material. There are two nozzle brackets 505, which are respectively mounted at both ends of the suction cup fixing plate 502 and fixed by bolts. Each suction cup fixing plate 502 is provided with a dust blowing nozzle 504. The dust blowing nozzle 504 is threadedly connected to the nozzle bracket 505. Each dust blowing nozzle 504 is connected to an external air compressor via an air pipe and is used to clean the surface of the board material by blowing dust before gripping the board material.

[0045] The linkage between the gripping component 5 and the Z-axis component 4 is as follows: when the Z-axis component 4 drives the Z-axis vertical beam 403 to rise and fall along the Z-axis direction, the Z-axis vertical beam 403 drives the suction cup fixing plate 502 and the vacuum suction cup 503, dust blowing nozzle 504 and other components set on it to rise and fall synchronously through the side fixing plate 501, so that the gripping component 5 can move closer to or away from the material so as to perform gripping and placement operations.

[0046] Furthermore, the dust blowing nozzle 504 is inclined, with the height of its air outlet lower than the height of the other end, and the horizontal height of the dust blowing nozzle 504 is greater than the horizontal height of the vacuum suction cup 503. This arrangement allows the gas ejected from the dust blowing nozzle 504 to be blown more effectively onto the surface of the board, while avoiding interference with the vacuum suction cup 503 during the gripping process.

[0047] In addition, this dual-station board loading machine includes a lifting platform for placing the boards and a conveying device, which can be either a non-powered roller table or a chain conveyor. The lifting platform can automatically adjust its height according to the stacking height of the boards to ensure that the top layer of boards is in a suitable gripping position, and the conveying device is used to transport the gripped boards to the next processing step.

[0048] Working principle:

[0049] Initial preparation stage: The lifting platform automatically adjusts to the preset position according to the stacking height of the boards to be loaded, ensuring that the top layer of boards is at a height easily accessible to the gripping component 5. At this time, the unpowered rollers or chain conveyor of the conveying device remain stationary, waiting to receive the boards. The entire equipment control system is in a standby state, and the sensors monitor the position of the boards and the initial state of each component of the equipment in real time.

[0050] When the control system issues a loading command, the X-axis motor 202 responds quickly and starts. Its output shaft, through the tight engagement of the synchronous belt 207 and the synchronous pulley, stably transmits torque to the X-axis drive rod 204, causing it to rotate at a set stable speed. The X-axis drive rod 204, through elastic couplings at both ends, synchronously transmits rotational power to two sets of X-axis drive rods 205, allowing them to rotate smoothly under the support of deep groove ball bearings at both ends of the bottom crossbeam 201. The rotation of the X-axis drive rod 205 drives the X-axis synchronous pulleys on it to rotate synchronously, thereby driving the synchronous belt 207, which is fitted onto the synchronous pulleys, to move precisely horizontally. The synchronous belt 207, through the synchronous belt pressure plate 208, drives the Y-axis crossbeam 301 to slide smoothly along the guide rail of the X-axis linear guide pair 206, ultimately precisely moving the Z-axis assembly 4 and the gripping assembly 5 directly above the lifting platform. At this point, the X-axis motor 202 receives the position signal and stops operating, completing the X-axis positioning.

[0051] Following this, Y-axis motor 302 and Y-axis motor 311 start simultaneously under the precise synchronous control of the control system, with their speeds and directions strictly maintaining consistency. The output shaft of Y-axis motor 302 drives the drive gear 310 to rotate. Since the drive gear 310 meshes with two racks 309 simultaneously, under the action of gear meshing transmission, the drive gear 310 is displaced relative to the racks 309, thereby driving the Y-axis motor 302, the Y-axis motor base plate 303, and related connected components to move. At the same time, under the guiding and limiting action of the guide wheel 304 on the racks 309, the accuracy of the movement direction is ensured. The vertical connecting plate 307 moves along the Y-axis direction through the Y-axis linear guide pair 306 on the Y-axis side connecting frame 305. Simultaneously, the output torque of Y-axis motor 311 is transmitted to Y-axis shaft 314 via synchronous belt and synchronous pulley, causing Y-axis shaft 314 to rotate. Y-axis shaft 314 drives Y-axis synchronous pulley 315 to rotate, causing Y-axis synchronous belt 313 to translate. Y-axis synchronous belt 313 drives Y-axis synchronous belt pressure plate 316 to move linearly along Y-axis linear guide pair 312 in the Y-axis direction. Since Y-axis synchronous belt pressure plate 316 is connected to Y-axis motor 302, it drives Y-axis motor 302 and related components to move synchronously, further driving Z-axis assembly 4 to move in the Y-axis direction. The two work together to achieve precise alignment of the two gripping components 5 with the two plates on the lifting platform. Subsequently, Y-axis motor 302 and Y-axis motor 311 stop working.

[0052] The Z-axis motor 402 starts, and its output torque is transmitted to the lead screw of the Z-axis transmission lead screw pair 401 through the coupling, causing the lead screw to rotate. Since the lead screw and the lead screw nut seat are connected by threads, the rotation of the lead screw is converted into the linear motion of the lead screw nut seat. Under the guidance of the Z-axis linear guide pair 404, the lead screw nut seat drives the Z-axis vertical beam 403 and the gripping assembly 5 to descend smoothly along the Z-axis. When the gripping assembly 5 approaches the board, the dust-blowing nozzle 504 connected to the external air compressor starts to work. The inclined dust-blowing nozzle 504 sprays high-pressure gas to thoroughly clean the surface of the board, removing surface dust and impurities to avoid affecting the subsequent adsorption effect. As the gripping assembly 5 continues to descend, the vacuum suction cup 503 contacts the surface of the board. At this time, the external vacuum generator starts, creating negative pressure inside the vacuum suction cup 503, firmly adsorbing the board.

[0053] After the material is firmly adsorbed, the Z-axis motor 402 reverses, driving the Z-axis vertical beam 403 and the gripping assembly 5 to lift the material along the Z-axis to the set height. Subsequently, the X-axis motor 202 starts again, driving the Y-axis transverse assembly 3, Z-axis assembly 4, and gripping assembly 5, along with the material, to move along the X-axis through the previous transmission path, transferring the material above the conveyor device.

[0054] Upon reaching the top of the conveyor, the X-axis motor 202 stops operating. Next, Y-axis motors 302 and 311 work together again to adjust the position of the material along the Y-axis, ensuring precise alignment with the receiving area of ​​the conveyor. Then, the Z-axis motor 402 rotates forward, lowering the material to the surface of the conveyor. The vacuum generator stops, and the vacuum suction cup 503 releases the material, which is then placed stably on the conveyor. In the reset phase, the Z-axis motor 402 reverses, raising the gripping assembly 5 to its initial height. The X-axis motor 202, Y-axis motors 302 and 311 work together to move the gripping assembly 5 back above the lifting platform, preparing for the next gripping and loading operation. Simultaneously, the conveyor starts, transporting the placed material to the next processing step, completing one full loading cycle.
