Detailed Implementation

[0034] Please refer to the illustrations, where the same component symbols represent the same components. The following description is based on the specific embodiments of this application illustrated, and should not be regarded as limiting other specific embodiments not detailed herein.

[0035] In related technologies, a single camera is used to correspond to a single cutting head to perform contour cutting tasks. When faced with some simple cutting needs, such as cutting ordinary whiteboard products, it is only necessary to cut out the required shape simultaneously. The technical requirements are relatively low and can meet basic production needs.

[0036] However, contour cutting demands not only precision but also efficiency, making a single cutting head insufficient. The key difference between contour cutting and simple cutting lies in its stringent requirements for precision and graphic adaptability. In contour cutting, a pattern is first printed on the product. Then, the cutting machine uses a high-resolution camera or other high-precision image acquisition device to capture markings on the product's surface. These markings serve as positioning reference points, carrying crucial coordinate information. Contour cutting is then performed based on the coordinates determined by these markings.

[0037] Generally, using a single cutting head for contour cutting can meet basic cutting needs. However, when attempting to expand the cutting head to two or more to improve cutting efficiency, many challenges arise. Since it's impossible to guarantee that all products to be cut are perfectly parallel to the X-axis track in actual operation, when multiple cutting heads are working simultaneously, the first cutting head may be able to cut accurately according to the predetermined program, but the remaining cutting heads are prone to displacement deviations, making it difficult to synchronously and accurately complete contour cutting.

[0038] While multi-head cutting technology is used in coil processing, the key component is the alignment system. This system typically consists of high-precision sensors, a controller, and an actuator. The sensors monitor the relative position of the product to be cut and the X-axis track of the cutting head in real time. If tilting or offset is detected, the sensor quickly transmits a signal to the controller. The controller performs rapid calculations based on a preset algorithm, accurately determining the required adjustment range, and then drives the actuator to adjust the position of the product. Through continuous dynamic monitoring and adjustment, the X-axis track of the cutting head is kept parallel at all times, effectively avoiding accuracy errors. This solution is relatively mature at present, given the low frequency of coil material changes. However, the application scenarios of this mature solution are clearly limited; it is only applicable to coil materials and cannot be widely extended to the cutting and processing of other types of products, making it difficult to meet diverse production needs.

[0039] Based on this, embodiments of this application provide a multi-head cutting machine to improve the efficiency of contour cutting while simultaneously enabling contour cutting with multiple cutting heads. It is understood that the multi-head cutting machine provided in these embodiments can also perform simple cutting. Please refer to... Figure 1 , Figure 2 and Figure 3This application describes a multi-head cutting machine according to an embodiment. The multi-head cutting machine includes a cutting frame and a cutting platform 200, with the cutting platform 200 located below the cutting frame. Multiple cutting heads are mounted on the cutting frame for cutting products, and the cutting platform 200 is used to hold the products to be cut.

[0040] The cutting frame includes a crossbeam track 100, on which multiple cutting heads are arranged in parallel, each capable of moving along the crossbeam track 100. Additionally, each cutting head is equipped with a corresponding second-axis motor, which drives the blade holder of the corresponding cutting head to move along a second axis. The crossbeam track 100 is parallel to a first axis, and the first and second axes are perpendicular to each other. In one embodiment, the crossbeam track 100 can be arranged along the Y-axis, i.e., along the first axis, and the second-axis motor can also drive the blade holder of the cutting head to move along the X-axis, i.e., along the second axis, thus enabling each cutting head to move independently along both the X and Y axes. Understandably, in another embodiment, the first axis can also be the X-axis direction, and the second axis can also be the Y-axis direction; this is not limited here and can be set according to actual needs.

[0041] Exemplarily, the plurality of cutting heads includes at least one fixed cutting head 120 and at least one adjustable cutting head 110. The fixed cutting head 120 is used for coordinate positioning of the product to be cut, and the tool holder position and cutting direction of the fixed cutting head 120 are fixed, while the tool holder position and cutting direction of the adjustable cutting head 110 are adjustable. This embodiment of the application, on the one hand, uses the fixed cutting head 120 for cutting positioning, and on the other hand, uses the adjustable cutting head 110 to flexibly adjust based on the cutting positioning of the fixed cutting head 120, thereby ensuring asynchronous cutting by the fixed cutting head 120 and the adjustable cutting head 110, and accurate positioning, thus improving the efficiency and accuracy of contour cutting.

[0042] In this embodiment, a fixed cutting head 120 can be provided, but the number of adjustable cutting heads 110 can be increased or decreased according to the cutting requirements. For example, more adjustable cutting heads 110 can be provided when there are many cutting surfaces, and fewer adjustable cutting heads 110 can be provided when there are few cutting surfaces.

[0043] For example, the adjustable cutting head 110 can also be configured to be detachably connected to the crossbeam rail 100 to facilitate the addition or removal of the adjustable cutting head 110.

[0044] When controlling the adjustable cutting head 110, the adjusting component thereon can be activated to control the movement of the cutter holder of the adjustable cutting head 110 along the first axis, that is, along the y-axis direction. Specifically, the movement of the cutter holder of the adjustable cutting head 110 along the y-axis direction controlled by the adjusting component is parallel to but does not coincide with the movement of the adjustable cutting head 110 along the Y-axis direction.

[0045] In some embodiments, each of the multiple cutting heads can move along the crossbeam track 100. Specifically, the crossbeam track 100 includes a crossbeam support structure and a cutting track. The crossbeam support structure supports the cutting track, so that the cutting track is fixedly arranged along a first axial direction and located above the cutting platform 200. The multiple cutting heads are slidably connected on the cutting track, and the multiple cutting heads are arranged side by side on the cutting track. There are various ways to arrange the multiple cutting heads in a slidable connection, such as by setting a controller to control the movement distance and position of each cutting head on the sliding track, or by manually moving the relative position of each cutting head on the sliding track. Each cutting head is provided with a corresponding groove that fits into the sliding track to realize the slidable connection between each cutting head and the sliding track.

[0046] Of course, in some cases, the position of each cutting head on the cutting track can be fixed, and each cutting head can be detachably connected to the sliding track to facilitate increasing or decreasing the number of adjustable cutting heads 110. For example, by providing through holes in the cutting track, each cutting head can be connected to the cutting track by bolts.

[0047] In some embodiments, the second-axis motor configured for each cutting head can be located at both ends of the track beam. Each second-axis motor is connected to each cutting head via a belt drive. Using a belt drive effectively buffers the impact force generated when the second-axis motor starts and stops, preventing damage to the cutting head and related precision components due to instantaneous impact, thus greatly extending the service life of the equipment. Furthermore, the belt drive's good flexibility allows it to adapt to minor displacement deviations caused by material properties, changes in the cutting path, and other factors during the cutting process, ensuring the smoothness of the cutting head's movement.

[0048] Each second-axis motor can be driven synchronously or asynchronously. For tasks requiring extremely high cutting precision and consistency, such as batch cutting of precision products, synchronous drive mode can be selected. This ensures the cutting head moves along the crossbeam track 100 at the same speed and acceleration, guaranteeing a highly consistent movement trajectory of each cutting head along the second axis, effectively improving product quality stability. For special cutting needs, such as processing products with irregular shapes or made of different materials, asynchronous drive mode can be used. The controller can individually adjust the operating parameters of each second-axis motor along the second axis, allowing the cutting head to flexibly adjust its movement speed and pause time according to actual conditions, achieving differentiated cutting and better adapting to complex and varied cutting tasks.

[0049] Please see Figure 4 , Figure 5 and Figure 6 The structure of the adjustable cutting head 110 is shown. In some embodiments, the adjustable cutting head 110 includes an adjustment assembly for controlling the movement of the cutter holder on the adjustable cutting head 110 along a first axial direction. The adjustment assembly also includes a first-axis motor 117, which drives the cutter holder on the adjustable cutting head 110 along the first axial direction. Specifically, one adjustment assembly is provided on one adjustable cutting head 110, and one first-axis motor 117 is provided on one adjustment assembly; each first-axis motor 117 drives one cutter holder along the first axial direction.

[0050] In some embodiments, the adjustment assembly further includes a linear guide rail 115, on which the tool holder on the adjustable cutting head 110 is disposed. The linear guide rail 115 is arranged along a third axis, i.e., along the Z-axis direction, wherein the third axis is perpendicular to the first axis and the second axis. This allows the tool holder on the adjustable cutting head 110 to move along the first axis (y-axis direction), the second axis (X-axis direction), and the third axis (Z-axis direction), respectively, enabling the tool holder of the adjustable cutting head 110 to be flexibly adjusted in various directions to adapt to the cutting needs of various products to be cut.

[0051] For example, the first axis motor 117 can be connected to the tool holder of the adjustable cutting head 110 via a trapezoidal lead screw 116. The first axis motor 117 drives the tool holder of the adjustable cutting head 110 to move along the first axis (y-axis direction). When the first axis motor 117 is running, it can accurately convert the rotational power it outputs into linear displacement of the tool holder along the y-axis direction.

[0052] Furthermore, the tool holder on the adjustable cutting head 110 can move along a linear guide rail 115 laid along the third axis (Z-axis direction). A third-axis motor 113 can also be installed on the adjustable cutting head 110, driving the tool holder to move along the linear guide rail 115. This reduces the frictional force experienced by the tool holder sliding on the linear guide rail 115, improving the accuracy and stability of the tool holder's movement in the Z-axis direction.

[0053] Furthermore, the linear guide rail 115 is designed to work closely with the first axis motor 117 and the trapezoidal lead screw 116 in a three-in-one configuration, enabling the tool holder to achieve omnidirectional, high-precision, stable and reliable positioning and dynamic movement in three-dimensional space, effectively meeting the stringent requirements for tool holder position control in various complex graphic contour cutting scenarios.

[0054] Specifically, the adjustable cutting head 110 includes a cutting head drive plate 111, a motor holder 112, and a cutting blade holder 114 connected sequentially from top to bottom. The cutting head drive plate 111 is connected to the cutting track, the motor holder 112 is used to install or place the third axis motor 113 of the adjustable cutting head 110, and the cutting blade holder 114 is used to install or place the blade holder and the first axis motor 117 of the adjustable cutting head 110.

[0055] Please see Figure 7 , Figure 8 and Figure 9 The structure of the provided fixed cutting head 120. In some embodiments, an image acquisition device 125 is provided below the fixed cutting head 120, and the scanning direction of the image acquisition device 125 is downward, that is, the scanning direction of the image acquisition device 125 is parallel to the third axis and faces the cutting platform 200.

[0056] When a product to be cut is placed on the cutting platform 200, the camera in the image acquisition device 125 faces the product to be cut in order to scan the product and obtain the marking information of the product to be cut, so as to facilitate the determination of the coordinate position of the fixed cutting head 120 and the coordinate position of the marking information based on the marking information.

[0057] In some embodiments, the tool holder of the fixed cutting head 120 is driven by a third-axis motor 123 along a third axis, meaning the tool holder of the fixed cutting head 120 can move in the Z-axis direction. The tool holder of the fixed cutting head 120 can be mounted on a linear guide rail, which is positioned along the third axis. Under the drive of the third-axis motor 123, the tool holder on the fixed cutting head 120 can move along the linear guide rail laid along the third axis (Z-axis direction).

[0058] In addition, the fixed cutting head 120 is also driven by its configured second-axis motor to move in the second axis (X-axis direction). This enables the tool holder of the fixed cutting head 120 to move in the first and second axes via the first and second-axis motors, thereby controlling whether the tool holder of the fixed cutting head 120 performs cutting, as well as the cutting pressure and speed, to cut the product to be cut.

[0059] In some embodiments, the fixed cutting head 120 includes a cutting head drive plate 121, a motor retainer 122 and a camera bracket 126 connected sequentially from top to bottom. The cutting head drive plate 121 is connected to the crossbeam rail 100. The motor retainer 122 is used to install or place the third axis motor 123. The camera bracket 126 is used to install or place the image acquisition device 125.

[0060] The fixed cutting head 120 also includes a cutting blade holder 124, which is disposed between the motor retainer 122 and the camera bracket 126. The cutting blade holder 124 is used to mount the blade holder of the fixed cutting head 120.

[0061] In some embodiments, the multi-head cutting machine includes: a controller, which is communicatively connected to the image acquisition device 125 and the adjustable cutting head 110 respectively;

[0062] The image acquisition device 125 is used to scan the marking information of the product to be cut and send the marking information to the controller;

[0063] The controller is used to control the movement direction of the adjustable cutting head 110 according to the marking information.

[0064] In this embodiment, when performing contour cutting, a marking pattern can be printed on the product to be cut first. Then, the marking pattern on the product to be cut is acquired by the image acquisition device 125 to obtain the marking information, and the marking information is transmitted to the controller. The controller can be set on the fixed cutting head 120, the adjustable cutting head 110, or the crossbeam support structure. The specific setting location is not limited in this embodiment and can be set according to actual needs.

[0065] The controller can be equipped with an intelligent algorithm based on image processing technology. This algorithm identifies, analyzes, and extracts features from the collected marking information, converting the marking information into coordinate data to locate the relative position of the fixed cutting head 120 and the marking image in the product to be cut. Based on this relative position, the cutting path of the fixed cutting head 120 and the adjustable cutting head 110 is constructed, and the fixed cutting head 120 and the adjustable cutting head 110 are asynchronously driven to cut the product to be cut, thereby improving the efficiency of contour cutting of the product to be cut.

[0066] For example, to ensure the accuracy of contour cutting, the intelligent algorithm also employs strategies such as multi-point calibration and dynamic compensation. Multi-point calibration refers to measuring and correcting multiple marker points from different angles and positions before cutting, eliminating errors introduced by factors such as the placement of the product to be cut and the image acquisition angle, resulting in more accurate initial coordinate positioning. The dynamic compensation mechanism monitors the deviation between the actual position of the cutting head and the preset path in real time during the cutting process. Once a deviation is detected, the adjustment amount is immediately calculated based on the preset compensation model and fed back to the controller, ensuring that the cutting head accurately cuts along the graphic contour at all times.

[0067] The controller is also communicatively connected to the motors of each axis of the adjustable cutting head 110, so as to control the movement of the cutter holder of the adjustable cutting head 110 in three-dimensional space through the motors, thereby achieving accurate adjustment of the orientation of the adjustable cutting head 110. This ensures that the cutting trajectory perfectly matches the graphic contour, achieving high-precision cutting and meeting the needs of fields with extremely high cutting accuracy requirements.

[0068] In some embodiments, a cutting platform 200 is positioned below the cutting frame and is used to hold the product to be cut. The cutting platform 200 is driven along a first axis by a drive mechanism, including roller type and platform type.

[0069] The roller-type cutting platform includes a cutting platform 200, rollers located on both sides or around the bottom of the cutting platform 200, a matching drive shaft, and a power transmission device. The drive shaft and rollers are connected by bearings to ensure smooth and flexible roller rotation and minimize energy loss during power transmission. When the multi-head cutting machine starts its cutting task, the torque output from the power source (such as a motor) is transmitted to the drive shaft via a power transmission device such as a belt, chain, or gear set, thereby driving the rollers to rotate synchronously. The rollers, relying on the friction between themselves and the bottom track or support surface of the cutting platform 200, propel the cutting platform 200 along a first axial direction. The roller-type drive smoothly propels the cutting platform 200, ensuring that the product to be cut is not affected by additional impact forces during the cutting process, guaranteeing the flatness and precision of the cut edges.

[0070] The platform-type cutting platform includes a cutting platform 200 and a linear module located at the bottom of the cutting platform 200. The linear module includes a slider, a guide rail, and a drive motor. When the multi-head cutting machine starts the cutting task, the power source (such as a motor) outputs power according to the command, driving the slider to slide quickly and smoothly along the guide rail. The cutting platform 200 is moved accordingly, so as to control the movement of the cutting platform 200 with extremely high positioning accuracy and perform fine cutting on the product to be cut.

[0071] In summary, the multi-head cutting machine provided in this application, by arranging multiple cutting heads side-by-side on the crossbeam track of the cutting machine frame, can simultaneously perform multi-point cutting on the product to be cut. Compared with traditional single-head cutting equipment, this significantly shortens the overall cutting operation time, especially in scenarios facing large-scale production tasks or requiring high cutting timeliness, effectively improving cutting efficiency. Furthermore, by setting fixed and adjustable cutting heads, during the cutting process, when the product to be cut experiences slight displacement or deformation, the fixed cutting head monitors the tool holder position in real time, quickly calculates the compensation amount based on an intelligent algorithm, and, in conjunction with the controller, coordinates with the controller to dynamically calibrate the tool holder of the adjustable cutting head in the corresponding axis in real time, ensuring the accuracy of multi-head cutting. Moreover, the tool holders on the fixed and adjustable cutting heads are driven by their respective second-axis motors along a second axis perpendicular to the first axis, making the motion control of the cutting head in the two-dimensional plane more precise, enabling accurate cutting along complex graphic contours. Furthermore, the adjustable cutting head's adjustment component can control the movement of the cutter holder along the first axis. Even when the product to be cut cannot be perfectly parallel to the crossbeam track (first axis), the cutting position can be dynamically adjusted in real time, ensuring that each cutting head can accurately conform to the graphic contour for cutting, meeting the requirements of high-precision contour cutting and effectively improving product quality. In addition, both the fixed and adjustable cutting heads are equipped with a third-axis motor, allowing their cutter holders to move along the third axis along a linear guide rail, thus enabling the adjustable cutting head to move flexibly in three dimensions.

[0072] The multi-head cutting machine provided in this application, with its combination of a fixed cutting head and an adjustable cutting head, is no longer limited to specific roll materials. Whether it's sheet material, roll material, or material with irregular surfaces or slight deformation, the adjustable cutting head allows for flexible adaptation, ensuring a smooth cutting process and greatly expanding the application range of the multi-head cutting machine to meet diverse cutting needs. The fixed cutting head can move freely in the X and Z axes. This multi-dimensional movement capability allows it to easily handle materials of varying thickness, hardness, and surface flatness. For example, when cutting thicker sheets, the Z-axis cutter height can be adjusted to precisely control the cutting pressure, ensuring smooth cutter entry into the material without excessive compression or deformation. For materials with uneven surfaces, the coordinated adjustment of the X and Z axes ensures the cutter maintains the optimal cutting posture at all times, adapting to material undulations and achieving smooth cutting.

[0073] Furthermore, the independent drive and control of each cutting head's blade holder reduces the impact of a single cutting head malfunction on the overall cutting operation, improving equipment stability. Simultaneously, the adjustable components of the adjustable cutting head, precisely controlled by the controller, can function stably and continuously during long-term, high-intensity cutting operations, reducing equipment maintenance frequency and lowering production costs.

[0074] The multi-head cutting machine provided in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
