Description

Technical Field

[0001] This application relates to the field of waste cleaning technology for machining centers, and more particularly to a waste cleaning mechanism for machining centers and a machining center using the same. Background Technology

[0002] In the field of intelligent manufacturing, six-sided drilling and milling machining centers are widely used in the sheet metal processing industry due to their high degree of automation, enabling unmanned continuous production. However, when processing steps such as corner cutting and hollowing out sheet metal are involved, a large amount of waste sheet metal is generated.

[0003] Currently, there is a lack of effective waste disposal mechanisms. This waste not only causes equipment parts to jam and become damaged during processing due to its random movement, affecting normal equipment operation, but also interferes with sensors in the material conveying stage, causing erroneous readings, leading to production interruptions or reduced product quality, and data corruption affecting the entire production line. Although some equipment is equipped with simple waste cleaning devices, they cannot be tailored to the shape and cutting rules of the waste, making it difficult to meet the needs of complex processing scenarios. Therefore, there is an urgent need for a waste disposal mechanism that can promptly grasp and accurately unload waste to ensure the efficient and stable operation of the six-sided drilling and milling machining center. Summary of the Invention

[0004] The purpose of this invention is to provide a waste cleaning mechanism for a machining center and a machining center using the same, which can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0014] The first servo drive mechanism is connected to the first slider.

[0015] On one hand, the first slider is connected to multiple second guide rails arranged parallel to the second moving path, and the second guide rails are connected to second sliders; and

[0016] A second servo drive mechanism is connected to the second slider, which can be used to drive it to move along the second guide rail.

[0017] On one hand, the material handling mechanism is connected to the second slider.

[0018] On one hand, the material handling mechanism includes:

[0019] A connecting base frame is connected to the second slider;

[0020] The first connecting rod is connected to the connecting base frame via a connecting panel and is located on the side of the connecting base frame;

[0021] The second connecting rod is fixedly connected to the first connecting rod, and the end of the second connecting rod is fixedly connected to a third connecting rod that is parallel to the first connecting rod;

[0022] The adsorption unit is connected to the first connecting rod and the third connecting rod.

[0023] On the one hand, the adsorption unit includes a front transverse adsorption unit, a front longitudinal adsorption unit, a rear transverse adsorption unit, and a rear longitudinal adsorption unit;

[0024] The front transverse adsorption unit and the front longitudinal adsorption unit are respectively disposed at the end of the third connecting rod;

[0025] The rear transverse adsorption unit and the rear longitudinal adsorption unit are respectively located on both sides of the second connecting rod and connected to the first connecting rod.

[0026] On the one hand, the front transverse adsorption unit, the front longitudinal adsorption unit, the rear transverse adsorption unit, and the rear longitudinal adsorption unit have the same structure, which includes:

[0027] An adsorption cylinder is connected to either the first connecting rod or the second connecting rod;

[0028] A gas distribution block is connected to the end of the cylinder rod of the adsorption cylinder, and multiple suction cups are connected to the gas distribution block; and

[0030] On the one hand, the second connecting rod is a telescopic connecting rod with adjustable length.

[0031] On the one hand, the third connecting rod is a telescopic connecting rod with adjustable length.

[0033] The beneficial effects of this application are as follows:

[0034] 1.

[0037] 4. The adsorption cylinder drives the suction cup to press down quickly. The mechanical pre-pressure ensures that the suction cup is in close contact with the surface of the waste material, which can effectively compensate for the suction loss caused by gaps in simple negative pressure adsorption.

[0038] 5. It can effectively improve the problems of low waste removal efficiency, poor adaptability, and insufficient stability of traditional machining centers. It not only significantly improves processing continuity and precision, but also reduces production costs through modular and flexible design. Attached Figure Description

[0057] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by this application clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0058] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0059] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0060] Please see Figures 1 to 7 This utility model discloses a machining center 100, which can be used to cut corners or hollow out sheet metal. During the cutting or hollowing out process, waste sheet metal is generated at the corners or center of the sheet metal. If this waste sheet metal is not processed in a timely manner, it will affect the subsequent processing of the sheet metal by the machining center 100.

[0061] The machining center 100 disclosed in this utility model is equipped with a waste cleaning mechanism, which can clean up waste sheet metal, thereby improving the subsequent processing effect of the machining center 100 on the workpiece. At the same time, the waste cleaning mechanism can promptly remove waste sheet metal generated during the processing, avoiding the accumulation of waste material that affects the subsequent processing of the workpiece by the machining center 100, and improving the continuity and efficiency of processing.

[0062] Specifically, the waste disposal mechanism of the machining center 100 includes a moving mechanism 200 and a picking mechanism 300. The moving mechanism 200 can move along a first moving path DX, which includes a first position 201 on one side of the worktable 110 of the machining center 100 and a second position 202 on the other side. The moving mechanism 200 can be used to drive the picking mechanism 300 to move between the first position 201 and the second position 202. It can be understood that when the picking mechanism 300 moves from the first position 201 to the second position 202, the picking mechanism 300 can cover the entire lateral area of ​​the worktable 110.

[0063] Furthermore, by driving the material handling mechanism 300 to move through the moving mechanism 200, flexible positioning and cleaning of waste materials at different locations on the board can be achieved. This is applicable to various processing scenarios such as cutting corners and hollowing out of the board, thereby improving the versatility and flexibility of the machining center 100.

[0064] In one embodiment, the material handling mechanism 300 is connected to the moving mechanism 200 and includes multiple independently controlled adsorption units 320. The independent adsorption units 320 can process multiple waste points in parallel, reducing the overall movement of the material handling mechanism 300 and shortening the cleaning cycle. Simultaneously, the material handling mechanism 300 employs multiple independently controlled adsorption units 320, allowing for individual control of the suction cups 3203 for waste of different locations and sizes, avoiding interference with unprocessed areas or other waste. This is particularly suitable for precise cleaning in complex processing scenarios, improving the flexibility and targeting of waste handling.

[0065] Furthermore, the adsorption unit 320 is equipped with a suction cup 3203 that can move along the second moving path DZ. The suction cup 3203 can be used to adsorb waste material on the connecting platform 110. It is understood that the second moving path DZ is set at an angle to the plane of the plate. Preferably, when the plate is on a horizontal plane, the second moving path DZ is perpendicular to the horizontal plane. Because the second moving path DZ is perpendicular to the plane of the plate, the suction cup 3203 can move closer to or further away from the platform 110 in the vertical direction, ensuring perpendicular contact with the waste surface during adsorption, enhancing adsorption stability, and preventing waste from falling off or adsorption failure due to tilted contact.

[0066] By coordinating the movement of the first moving path DX and the second moving path DZ, the waste material on the material platform 110 can be accurately positioned, vertically adsorbed, and quickly removed, ensuring that there are no blind spots in the cleaning process.

[0067] Therefore, in the actual waste removal process, after the sheet metal is cut on the machining center 100 and waste is generated, the material handling mechanism 300 moves above the waste via the first moving path DX and the material table 110. Then, the material handling mechanism 300 moves on the second moving path DZ and returns to the first position 201 after the waste is picked up by the suction cup 3203.

[0068] In one embodiment, a moving mechanism 200 is disposed within a machining center 100. The moving mechanism 200 includes a first crossbeam 210, a first guide rail 211, a first slider 212, and a first servo drive mechanism 213. Multiple first guide rails 211 are arranged parallel to each other along a first moving path DX, and the first guide rails 211 are connected to the first crossbeam 210. The first slider 212 is slidably connected to the first guide rail 211, and is driven to slide along the first guide rail 211 by the first servo drive mechanism 213.

[0069] Understandably, multiple first guide rails 211 are arranged in parallel on the first crossbeam 210 to form a multi-rail support structure, which can evenly distribute the weight of the material handling mechanism 300 and the adsorbed waste, reduce the load on a single rail, improve the overall rigidity and anti-deformation ability of the moving mechanism 200, and ensure stability in high-speed movement or heavy-load scenarios.

[0070] Furthermore, the first slider 212 is connected to a plurality of second guide rails 220 arranged parallel to the second moving path DZ, and a second slider 221 is connected to the second guide rails 220. A second servo drive mechanism 223 is connected to the second slider 221 for driving it to move along the second guide rails 220.

[0071] The first servo drive mechanism 213 and the second servo drive mechanism 223 achieve high-precision displacement through closed-loop control, ensuring that the material handling mechanism 300 accurately aligns with the waste material position along the first moving path DX and the second moving path DZ, which is especially suitable for scenarios with high processing accuracy requirements. At the same time, the adjustable speed and fast start / stop response of the servo drive can match the cycle time requirements of the machining center 100, avoiding efficiency loss due to motion lag.

[0072] The first guide rail 211 and the second guide rail 220 form an orthogonal two-dimensional motion platform, and the material handling mechanism 300 can realize a composite motion of horizontal translation and vertical lifting above the material platform 110.

[0073] Meanwhile, the modular design of setting the second guide rail 220 on the first slider 212 facilitates future upgrades and modifications, enhancing the flexibility and expandability of the equipment.

[0074] In one embodiment, the material handling mechanism 300 is connected to the second slider 221.

[0075] Furthermore, the material handling mechanism 300 includes a connecting base frame 310, a first connecting rod 311, and a second connecting rod 312. The connecting base frame 310 is connected to the second slider 221, so that the second slider 221 and the connecting base frame 310 are driven to move along the second moving path DZ by the second servo drive mechanism 223. The first connecting rod 311 is connected to the connecting base frame 310 via a connecting panel and is located on the side of the connecting base frame 310. The second connecting rod 312 is fixedly connected to the first connecting rod 311, and a third connecting rod 313, parallel to the first connecting rod 311, is fixedly connected to the end of the second connecting rod 312. The adsorption unit 320 is connected to the first connecting rod 311 and the third connecting rod 313.

[0076] Specifically, the adsorption unit 320 includes a front transverse adsorption unit 321, a front longitudinal adsorption unit 322, a rear transverse adsorption unit 323, and a rear longitudinal adsorption unit 324. The front transverse adsorption unit 321 and the rear transverse adsorption unit 323 are respectively located at the ends of the third connecting rod 313. The front longitudinal adsorption unit 322 and the rear longitudinal adsorption unit 324 are located on both sides of the second connecting rod 312 and connected to the first connecting rod 311. By constructing a multi-directional layout of the front transverse adsorption unit 321, the front longitudinal adsorption unit 322, the rear transverse adsorption unit 323, and the rear longitudinal adsorption unit 324, the material handling mechanism 300 can simultaneously cover the front, rear, left, and right areas of the material platform 110. It can achieve "three-dimensional surrounding" adsorption, especially for waste materials in complex locations such as corners and centers of plates, avoiding blind spots of traditional unidirectional adsorption and improving the comprehensiveness of cleaning. The distribution of each adsorption unit forms a spatial three-dimensional array, which can be flexibly combined and activated according to the location of the waste material, adapting to the waste distribution characteristics in various scenarios such as corner cutting and hollowing.

[0077] It should be noted that the front transverse adsorption unit 321, the front longitudinal adsorption unit 322, the rear transverse adsorption unit 323, and the rear longitudinal adsorption unit 324 have the same structure. They adopt a standardized modular design, facilitating unified procurement, replacement, and maintenance, and reducing spare parts inventory costs.

[0078] Specifically, the structure includes an adsorption cylinder 3201, a gas distribution block 3202, and a negative pressure device. The adsorption cylinder 3201 is connected to either a first connecting rod 311 or a second connecting rod 312. The gas distribution block 3202 is connected to the end of the cylinder rod of the adsorption cylinder 3201, and multiple suction cups 3203 are connected to the gas distribution block 3202. The suction cups 3203 are connected to the negative pressure device via tubes, which generates negative pressure at the opening of the suction cups 3203. Therefore, when the opening of the suction cup 3203 is in contact with the surface of the waste, the negative pressure generated at the opening by the negative pressure device allows the waste to be adsorbed onto the suction cup 3203. Understandably, the cylinder drives the suction cup 3203 to quickly approach the surface of the waste and apply pre-pressure to ensure a tight fit. The strong suction generated at the opening by the negative pressure device allows even large pieces of waste to be stably adsorbed, avoiding the breakage or detachment of waste caused by collisions in traditional mechanical gripping.

[0079] Furthermore, to improve the applicability of this device in actual use, the second connecting rod 312 and the third connecting rod 313 can be adjustable telescopic connecting rods. By setting the second connecting rod 312 and the third connecting rod 313 as adjustable telescopic connecting rods, it is possible to adapt to the waste generated by different sized plates. This improves the device's ability to ensure that the suction cup 3203 can always accurately contact the surface of waste materials of different specifications during actual use, avoiding the problem of not being able to reach the waste material due to mechanical structure fixation, and significantly improving the equipment's compatibility with plate sizes.

[0080] In summary, this disclosure provides a waste cleaning mechanism for a machining center and a machining center using the same. The waste cleaning mechanism is linked to the machining process, triggering a cleaning action immediately after machining is completed. This prevents waste accumulation from obstructing the machining area or interfering with the movement of the workpiece, ensuring seamless connection of subsequent processes and improving the stability of the machining cycle. Simultaneously, the moving mechanism 200 and the second guide rail 220 vertically lift and lower, allowing the material handling mechanism 300 to reach the waste area on the material table 110. The multi-directional layout of independent suction units forms a three-dimensional, enveloping cleaning network, which can individually activate corresponding units for waste in different locations on the workpiece, avoiding accidental contact or interference with unprocessed areas. The suction cylinder 3201 drives the suction cup 3203 to press down rapidly, ensuring a tight fit between the suction cup 3203 and the waste surface through mechanical pre-pressure, effectively compensating for suction loss caused by gaps in simple negative pressure suction.

[0081] Therefore, it can effectively improve the problems of low waste cleaning efficiency, poor adaptability and insufficient stability of traditional machining centers. It not only significantly improves the continuity and accuracy of processing, but also reduces production costs through modular and flexible design.
