Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wire cutting, in particular to a wire cutting device. BACKGROUND

[0002] In the wire cutting process, liquid is used for cooling, and the liquid will move with the wire net. Since the normal cutting speed of the cutting wire in the cutting process is in the range of 30-40 m / s, the liquid at the cutting position will be taken away and splashed by the cutting wire.

[0003] In the case of setting up a wire net monitoring system to monitor the wire net, in order to make the collected data more reliable, the timing of collecting data is selected in the process of reversing the cutting wire. In the process of reversing the cutting wire, the movement speed of the cutting wire will be reduced, and the splashing liquid will be less, so that the collected data is not easily affected by the splashing liquid.

[0004] According to the prior art wire cutting device, in order to reduce the influence from the liquid, data collection needs to be performed during the reversing of the cutting wire, the collection time is short, and data collection can only be performed according to the cycle of the reversing of the cutting wire. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to provide a wire cutting device which can reduce the influence of splashing liquid on the data collection process.

[0006] Embodiments of the present application are implemented as follows:

[0007] In a first aspect, the embodiments of the present application provide a wire cutting device, which includes a machine body, a cutting system and a wire net monitoring system arranged on the machine body. The cutting system includes a groove wheel assembly, a cutting wire connected to the groove wheel assembly to form a cutting wire net for cutting a workpiece, and a return wire net, and the cutting wire net is located above the return wire net. The wire net monitoring system includes a first data collection device, and a data collection end of the first data collection device is used for sampling the cutting wire. The first data collection device is arranged at a position outside a closed area surrounded by the cutting wire net in a state of being arranged on the groove wheel assembly, and is located on the same side of the return wire net as the cutting wire net. The data collection end of the first data collection device is arranged towards the return wire net to collect state data of the return wire net.

[0008] The line cutting device provided by the technical scheme has the following advantages. The first data acquisition device is located on the same side of the cutting wire net as the return wire net and is located outside the closed area formed by the cutting wire net and the return wire net. Therefore, the first data acquisition device is far away from the cutting workpiece position and is separated from the return wire net. The data acquisition end of the first data acquisition device faces the return wire net and acquires data of the return wire net. Therefore, the first data acquisition device is less affected by the splashing liquid from the contact position of the cutting wire net and the workpiece. Even if the first data acquisition device acquires data during the cutting of the workpiece, the acquired data has high accuracy. Even during the cutting process, the first data acquisition device can acquire data, and the splashing liquid has little effect on the data acquisition process of the first data acquisition device.

[0009] In some optional embodiments, the groove wheel assembly includes two first groove wheels and a second groove wheel, the cutting wire net is directly connected between the two first groove wheels, and the return wire net is connected from one first groove wheel to the other first groove wheel through the second groove wheel.

[0012] not higher than the vertical position of the axis of the first groove wheel; and / or

[0013] not lower than the vertical position of the axis of the second groove wheel.

[0014] During the cutting of the workpiece, part of the liquid used for cooling moves to the first groove wheel along with the cutting wire net. Therefore, if the first data acquisition device is arranged not higher than the vertical position of the axis of the first groove wheel, the influence of the liquid splashed from the cutting wire net on the first data acquisition device at the position of the first groove wheel can be reduced. If the first data acquisition device is arranged lower than the vertical position of the axis of the second groove wheel, the first data acquisition device is closer to the return wire net and can better acquire the state data of the return wire net.

[0015] In some optional embodiments, the first data acquisition device is arranged to satisfy the following conditions: not higher than the vertical position of the axis of the first groove wheel and not lower than the vertical position of the axis of the second groove wheel.

[0023] In some alternative embodiments, s is 140 to 240 mm.

[0024] When the first data acquisition device is arranged to meet the above requirements, the first data acquisition device is less affected by the liquid, and the accuracy of the acquired data is higher.

[0025] In some alternative embodiments, s is 170 to 200 mm.

[0026] When the first data acquisition device is arranged to meet the above requirements, the distance between the first data acquisition device and the second groove wheel in the horizontal direction is reasonable, and the state data of the return wire net can be conveniently and accurately acquired to determine whether the return wire net on the second groove wheel has a parallel connection and a jumper.

DETAILED DESCRIPTION

[0071] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0072] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0073] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0074] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly placed when the product of the present application is used, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0075] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly inclined. For example, "horizontal" only means that it is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0076] In the description of the present application, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "set", "install", "connect", "connect" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0077] In the online cutting device, the cutting line is wound on the groove wheel assembly 100 to form a closed area. The cutting line is a whole line (including the case of multiple lines connected into a whole line), which periodically moves forward and reverses during the cutting process of the workpiece 700. After passing through the workpiece 700, the cutting line moves away from the workpiece 700, and then returns to the position of the workpiece 700 along the winding path on the groove wheel assembly 100, and cuts the workpiece 700 again.

[0078] The cutting line is wound on the groove wheel assembly 100 to form a wire mesh, which includes a cutting line mesh 210 and a return line mesh 220. Both the cutting line mesh 210 and the return line mesh 220 are composed of multiple segments of the cutting line. Among them, the cutting line mesh 210 is a collection of segments of the cutting line that are located on the movement path of the workpiece 700 to be cut during the cutting process of the workpiece 700; the return line mesh 220 is a collection of segments of the cutting line that are located outside the movement path of the workpiece 700 to be cut during the cutting process of the workpiece 700. That is, the cutting line mesh 210 plays a role in cutting the workpiece 700. It is not difficult to understand that during the movement of the cutting line, the segments in the cutting line can be converted between the cutting line mesh 210 and the return line mesh 220. Specifically, the cutting line mesh 210 becomes the return line mesh 220 after passing through the groove wheel in the groove wheel assembly 100, and the return line mesh 220 can become the cutting line mesh 210 after passing through the groove.

[0079] During the cutting process, there is a large amount of liquid at the position where the cutting line mesh 210 contacts the workpiece 700 to play a role in cooling and removing dust. Since the cutting line mesh 210 directly contacts the workpiece 700 during the cutting process, it is generally believed in the prior art that in order to timely find abnormal conditions such as wire jumping, wire merging and wire breaking in the wire mesh that will affect the yield of the workpiece 700, data collection needs to be performed from the position of the cutting line mesh 210 close to the workpiece 700, even though the liquid will cause some shielding to the cutting line at that position, and the liquid splashing will affect the data collection device used for collecting data.

[0080] In the wire cutting device provided in the application, the first collecting device can be used to collect data of the return wire net 220. Although the return wire net 220 is away from the position of the cutting workpiece 700, the abnormal conditions such as wire connection and wire breakage can be transmitted between the return wire net 220 and the cutting wire net 210 along the movement of the cutting wire, because the return wire net 220 and the cutting wire net 210 are continuously converted in the movement process of the cutting wire. That is, the data collected from the return wire net 220 can also reflect the state of the position where the cutting wire net 210 contacts the workpiece 700 to a certain extent, so as to realize the prevention and monitoring of the abnormal conditions such as wire connection and wire breakage that may occur in the cutting wire. In addition, the data collected from the return wire net 220 is less affected by the liquid in the data collection process, and the collected data is more accurate and can more truly reflect the cutting wire net 210. The embodiment of the application provides a wire cutting device, which comprises a machine body, a cutting system, a wire net monitoring system and a clamping device for clamping a workpiece 700 arranged on the machine body, and the cutting system comprises a groove wheel assembly 100. It is not difficult to understand that the machine body serves to mount the cutting system, the wire net monitoring system and the clamping device. The groove wheel assembly 100 comprises two first groove wheels 110 located on one side of the clamping device. The two first groove wheels 110 are two groove wheels arranged side by side in the groove wheel assembly 100 and located on both sides of the position of the cutting workpiece 700 in the horizontal direction, that is, the two first groove wheels 110 are respectively located on both sides of the clamping device in the horizontal direction for clamping the workpiece 700 in the wire cutting device. One end of a segment in the cutting wire net 210 is connected to one first groove wheel 110, the other end of the segment is connected to the other first groove wheel 110, and the segment in the cutting wire net 210 is located on the side of the first groove wheel 110 facing the clamping device. One end of a segment in the return wire net 220 is connected to one first groove wheel 110, the other end of the segment is connected to the other first groove wheel 110, and the segment in the cutting wire net 210 is located on the side of the first groove wheel 110 away from the clamping device.

[0081] In the process of cutting the workpiece 700, the clamping device (not shown in the figure) clamps the workpiece 700 and drives the workpiece 700 to move from a position away from the cutting wire net 210 to the cutting wire net 210, and the cutting process of the workpiece 700 starts when the workpiece 700 contacts the cutting wire net 210. As will not be difficult for those skilled in the art to understand, the surface of the groove wheel is provided with a groove for accommodating the cutting wire, and the width of the groove is matched with the diameter of the cutting wire. Under normal circumstances, only one cutting wire is accommodated in each groove. Under normal circumstances, the circumferences of all the groove wheels in the groove wheel assembly 100 should be parallel to each other.

[0082] In the embodiments provided in the present application, the wire mesh monitoring system comprises a first data acquisition device 300, the first data acquisition device 300 is located outside the closed area surrounded by the cutting wire on the groove wheel assembly 100, and is located on the same side of the return wire mesh 220 as the cutting wire mesh 210; the data acquisition end of the first data acquisition device 300 is arranged towards the return wire mesh 220 to acquire the state data of the return wire mesh 220. Among them, the first data acquisition device 300 and the return wire mesh 220 located on the same side of the cutting wire mesh 210 does not mean that the first data acquisition device 300 is located on the same side of the return wire mesh 220 as a whole, but in the process of data acquisition, the data acquisition end of the first data acquisition device 300 can be located on the same side of the return wire mesh 220 as the cutting wire mesh 210; the data acquisition end of the first data acquisition device 300 comprises a structure capable of emitting and receiving the signal returned by the return wire mesh 220, for example, the data acquisition end comprises a radar sensor, or a laser sensor, or a visual sensor.

[0083] Taking the radar sensor as an example, the principle of collecting data is that the radar sensor generates radar waves of a specific frequency through a transmitter, which can continuously emit radar waves near the wire mesh, when the radar waves meet the cutting wire, part of the energy will be reflected back to the sensor 310, and the radar sensor captures and records the signal reflected back from the wire mesh through the receiver; therefore, the radar sensor can calculate the distance between the cutting wire and the radar sensor by analyzing the interval time of the transmitter signal and the related receiving signal, and by analyzing the direction of the received radar wave, the radar sensor can determine the angle of the cutting wire relative to the radar sensor. The data processing unit integrates the distance, angle and other information, when abnormal conditions such as line merging and line breaking occur, the area will not reflect the signal, so as to determine whether there is an abnormality on the return wire mesh 220.

[0084] In combination with Figure 3 It is not difficult to understand that since the first data acquisition device 300 and the return wire mesh 220 are located on the same side of the cutting wire mesh 210, the data acquisition end of the first data acquisition device 300 is far away from the position of the cutting workpiece 700, and the return wire mesh 220 is also interposed between them, so that the liquid such as cooling liquid used at the position of the cutting workpiece 700 during the cutting process is not easy to fall on the data acquisition end of the first data acquisition device 300, reducing the influence of the liquid on the first data acquisition device 300, so that the first data acquisition device 300 can collect data even in the process of cutting the workpiece 700, and the collected data has high accuracy. Therefore, in the wire mesh cutting equipment provided in the present application, the first data acquisition device 300 can continuously collect the state data of the return wire mesh 220, and through the collected data, whether the return wire mesh 220 has abnormal conditions such as line breaking or line merging can be analyzed.

[0085] InFigure 1 and Figure 3 In the illustrated embodiment, the Geneva assembly 100 includes two first Geneva wheels 110 and one second Geneva wheel 120. The closed shape formed by the cutting lines after the Geneva assembly 100 is approximately triangular. Segments in the cutting line mesh 210 are directly connected between the two first Geneva wheels 110; that is, when a segment in the cutting line mesh 210 moves from one first Geneva wheel 110 to another, it does not pass through any other Geneva wheel. Segments in the return wire mesh 220 move from one first Geneva wheel 110 through the second Geneva wheel 120 and then connect to the other first Geneva wheel 110. Further, the two first Geneva wheels 110 can be positioned at the same height (i.e., vertically), or one can be positioned higher than the other. Compared to... Figure 2 The Geneva assembly 100 shown includes only one embodiment with two first Geneva wheels 110. In both embodiments where the dimensions and relative positions of the first Geneva wheels 110 are the same, providing a second Geneva wheel 120 increases the area of ​​the closed pattern enclosed by the cutting line, facilitating the entry of the cut portion of the workpiece 700 into the area corresponding to the closed pattern. In some embodiments, the number of second Geneva wheels 120 in the Geneva assembly 100 may also be two, or other numbers.

[0086] In the embodiments of this application, the cutting wire mesh 210 can be understood as a collection of segments in the cutting wire that pass through the position of the workpiece 700, or located in... Figure 1 The cutting line 210 is a collection of horizontally positioned segments at the top. Both ends of the cutting line mesh 210 are connected to the first grooved wheel 110, and no other grooved wheels are connected between the two ends of the cutting line mesh 210. The other grooved wheels that the cutting line passes through besides the first grooved wheel 110 are the second grooved wheels 120. The return line mesh 220 can be understood as a collection of segments in the cutting line that start from one first grooved wheel 110, pass through the second grooved wheel 120, and finally reach another first grooved wheel 110.

[0087] In some embodiments, the first data acquisition device 300 is positioned no higher than the vertical axis of the first grooved wheel 110. Specifically, during data acquisition, the data acquisition end of the first data acquisition device 300 is positioned no higher than the vertical axis of the first grooved wheel 110. (Combined with...) Figure 3 It's easy to understand that during the cutting process, due to the action of the workpiece 700, the cutting wire mesh 210 bends downwards. As the cutting wire mesh 210 moves from the position of the workpiece 700 towards the first grooved wheel 110, its direction of movement is obliquely upwards. At the position of the first grooved wheel 110, the trajectory of the cutting wire changes, causing the liquid adhering to the cutting wire mesh 210 to move along... Figure 3As indicated by the middle arrow A, the liquid is thrown out. Therefore, when the position of the data acquisition end of the first data acquisition device 300 is not higher than the vertical position of the axis of the first grooved wheel 110, the impact of the thrown-out liquid on the first data acquisition device 300 can be reduced. Furthermore, when the axes of the two first grooved wheels 110 are at different vertical positions, the data acquisition end of the first data acquisition device 300 is lower than the axis of the first grooved wheel 110 that is closer to it.

[0088] In some embodiments, the first data acquisition device 300 is positioned at a height not lower than the vertical position of the axis of the second grooved wheel 120, so that the first data acquisition device 300 is closer to the return network 220 and can better acquire the status data of the return network 220. This can be achieved by only the data acquisition end of the first data acquisition device 300 having the axis of the first and second grooved wheels 120 in a vertical position, or by the entire first data acquisition device 300 or a portion thereof having the axis of the second grooved wheel 120 in a vertical position.

[0089] In some embodiments, the first data acquisition device 300 is positioned neither higher than the vertical position of the axis of the first grooved wheel 110 nor lower than the vertical position of the axis of the second grooved wheel 120. For example, during data acquisition, the data acquisition end of the first data acquisition device 300 is positioned neither higher than the vertical position of the axis of the first grooved wheel 110 nor lower than the vertical position of the axis of the second grooved wheel 120.

[0090] Furthermore, such as Figure 4 As shown, the vertical distance between the first grooved wheel 110 and the second grooved wheel 120 is denoted as H, and the vertical distance between the first data acquisition device 300 and the first grooved wheel 110 is denoted as h. The ratio of h to H is between 0.16 and 0.63, specifically, it can be 0.16, 0.2, 0.3, 0.4, 0.5, 0.6, and 0.63, etc. h represents the vertical distance between the data acquisition end of the first data acquisition device 300 and the first grooved wheel 110 during data acquisition. The ratio of h to H is within this range, ensuring that the data acquisition end of the first data acquisition device 300 is positioned neither higher than the vertical axis of the first grooved wheel 110 nor lower than the vertical axis of the second grooved wheel 120. This allows the first data acquisition device 300 to be relatively close to the return network 220 vertically, facilitating the acquisition of the return network 220's status data. Furthermore, in some embodiments, the vertical distance between the first data acquisition device 300 and the second grooved wheel 120 is 50-190mm. That is, during the data acquisition process, the vertical distance between the data acquisition end of the first data acquisition device 300 and the second grooved wheel 120 is 50-190mm, preferably 110-130mm, so as to achieve more accurate acquisition of the status data of the return network 220.

[0091] In some embodiments, the distance between the second groove wheel 120 and a first groove wheel 110 close to the first data acquisition device 300 in the horizontal direction is L, the distance between the first data acquisition device 300 and the second groove wheel 120 in the horizontal direction is s, and the ratio of s to L is in the range of 0.67-1.22, and can be 0.67, 0.7, 0.8, 0.9, 1.0, 1.2, 1.22, etc. s is the distance between the data acquisition end of the first data acquisition device 300 and the second groove wheel 120 in the horizontal direction during data acquisition. In this embodiment, the data acquisition end of the first data acquisition device 300 is closer to the return line net 220, and can more conveniently acquire the state data of the return line net 220. In some embodiments, s is 140-240 mm, and is preferably 170-200 mm.

[0092] In Figure 3 With Figure 6 In the embodiment shown, the second groove wheel 120 divides the return line net 220 into a first sub-line net 221 and a second sub-line net 222. The first sub-line net 221 is located between a first groove wheel 110 and the second groove wheel 120, and the second sub-line net 222 is located between another first groove wheel 110 and the second groove wheel 120. Further, as shown in Figures 5 to 8 It can be understood that one of the first data acquisition devices 300 is used to acquire the state data of the first sub-line net 221, and the other first data acquisition device 300 is used to acquire the state data of the second sub-line net 222; for example, the data acquisition end of one of the first data acquisition devices 300 is arranged to face the first sub-line net 221, and the data acquisition end of the other first data acquisition device 300 is arranged to face the second sub-line net 222. Since two first data acquisition devices 300 are arranged to acquire the state data of the return line net 220 from both sides of the return line net 220, the amount of data obtained can be more, and thus the state of the return line net 220 can be more accurately judged, and errors can be reduced.

[0093] In some embodiments of the present application, the first data acquisition device 300 can also be arranged in a position-adjustable structure, specifically, the position of the data acquisition end of the first data acquisition device 300 can be changed so as to adjust the sampling position of the first data acquisition device 300 and the acquisition range of the first data acquisition device 300 on the return wire net 220. The sampling position is the position of the data acquisition end of the first data acquisition device 300 in space, and the acquisition range is the size of the area of the return wire net 220 that is acquired by the first data acquisition device 300, which includes both the number of segments in the axial direction of the groove wheel assembly 100 that are acquired and the area of the segment that is acquired. The axial direction of the groove wheel assembly 100 is the axial direction of the first groove wheel 110 or the axial direction of the second groove wheel 120. For example, in some embodiments, the wire net monitoring system includes a first mounting frame 400 connected to the machine body, and the first data acquisition device 300 is movably connected to the first mounting frame 400. Since the first data acquisition device 300 can move on the first mounting frame 400, the position of the data acquisition end of the first data acquisition device 300 can be changed, and thus the sampling position can be changed. In the case that the distance between the data acquisition end and the return wire net 220 changes due to the change of the position of the data acquisition end, both the number of segments sampled by each first data acquisition device 300 and the size and position of the area sampled in each segment can be changed, and thus the acquisition range can be changed.

[0094] Further, the first data acquisition device 300 is rotationally connected to the first mounting frame 400, so that the data acquisition end of the first data acquisition device 300 can rotate in a vertical plane. Further, the range of the signal emitted by the data acquisition end (i.e. the angle α1 shown in FIG. 1) is in the range of 30°-90°; the installation angle of the first data acquisition device 300 is such that the acute angle (i.e. the angle α2 shown in FIG. 1) between the path of the signal emitted by the data acquisition end and the horizontal plane is in the range of -60°-60°, i.e. α2 can be above the horizontal plane or below the horizontal plane. In this range, the inclination of the data acquisition end is appropriate, which can reduce the liquid falling onto the data acquisition end and reduce the influence on the accuracy of the acquired data. For example, Figure 7 Figure 7 Figure 6 Figure 7 ​​​As shown, since the first data collection end can rotate in the vertical plane, the signal receiving angle of the first data collection device 300 during the collection process can be adjusted, and thus the sampled area in the return wire net 220 is adjusted, that is, the area of the corresponding segment in the return wire net 220 collected by the first data collection device 300 is changed. In some other embodiments, the rotation of the data collection end in the vertical plane can also be achieved by the rotation connection of the first mounting frame 400 and the machine body. In some other embodiments, the first data collection device 300 can also be achieved by rotating the data collection end of the first data collection device 300 in the horizontal plane. That is, the collection range is adjusted by the data collection end that can rotate in the horizontal plane.

[0095] In some embodiments of the present application, as shown in Figure 9 With Figure 10 As shown, the first mounting frame 400 further comprises a guide rail 410 and a connecting rod 420 arranged on the guide rail 410, the guide rail 410 is connected to the machine body, and the extension direction of the guide rail 410 is parallel to the axis direction of the groove wheel assembly 100. The guide rail 410 and the connecting rod 420 are relatively slidably connected, and the relative sliding direction is parallel to the extension direction of the guide rail 410. The first data collection device 300 is rotationally arranged on the connecting rod 420. In this embodiment, the first data collection device 300 can not only rotate, but also slide along the extension direction of the guide rail 410 together with the connecting rod 420; the first data collection device 300 has high degrees of freedom, and can monitor the return wire net 220 from more positions and collect data from more positions of the return wire net 220.

[0096] In some embodiments, the connecting rod 420 can also be a telescopic rod, that is, the connecting rod 420 has a telescopic function, so that the position of the first data collection device 300 can be adjusted, and thus the distance between the first data collection end and the return wire net 220 is adjusted. As shown in Figure 11 With Figure 12 As shown in the embodiment, the connecting rod 420 is vertically arranged, and the connecting rod 420 comprises a first part 421 and a second part 422, wherein the first part 421 is provided with a plurality of vertically distributed hole structures, and the second part 422 is provided with a protrusion. By matching the protrusion of the second part 422 with the hole structures at different positions in the first part 421, the length of the connecting rod 420 can be changed; that is, as shown in Figure 6 With Figure 8As shown, the length of the connecting rod 420 is different when the protrusion of the second part 422 is located in the hole-like structure at different positions of the first part 421, thereby changing the position of the first data acquisition device 300 in the vertical direction. Further, a plurality of hole-like structures distributed in the vertical direction can be provided on the second part 422, and the first part 421 is provided with a protrusion. In other embodiments, other structures can be used to change the length of the connecting rod 420. In other embodiments, the connecting rod 420 can be arranged horizontally or obliquely. Further, the first part 421 is connected to the guide rail 410 in a sliding manner, and the second part 422 is connected to the first data acquisition device 300.

[0097] In the above embodiments, the connecting rod 420 can slide along the guide rail 410, which makes it more convenient to adjust the position of the first data acquisition device 300 in the axial direction of the first groove wheel 110.

[0098] Further, in some embodiments, the first part 421 and the second part 422 can also be connected in a rotating manner, a plurality of hole-like structures distributed in the circumferential direction are provided on the first part 421, and the second part 422 is provided with a protrusion. The center of the circumference is a point on the axis of rotation of the first part 421 and the second part 422. By matching the protrusion of the second part 422 with the hole-like structure at different positions of the first part 421, the rotation of the first data acquisition device 300 in the vertical plane can be realized.

[0099] Further, in some embodiments, the connecting rod 420 can be connected to a driving device to drive the connecting rod 420 to move along the extension direction of the guide rail 410. In this embodiment, the process of moving the first data acquisition device 300 together with the connecting rod 420 can be realized to sample different positions of the return wire net 220. The driving device can be a screw nut structure, in which the nut is connected to the lead screw 510, as shown in Figure 9 The axis direction of the lead screw 510 is parallel to the extension direction of the guide rail 410, and the connecting rod 420 is driven by the nut to move along the extension direction of the guide rail 410 during the rotation of the lead screw 510. Of course, a cylinder or other structure can also be used as the driving device to drive the connecting rod 420 to move. In addition, in this embodiment, since the driving device is provided to drive the connecting rod 420 to move, the movement of the connecting rod 420 and the first data acquisition device 300 can be controlled, and therefore, the wire cutting equipment provided in this embodiment can realize the uninterrupted reciprocating movement of the first data acquisition device and the acquisition of the state data of the return wire net 220 during the working process, which can more timely discover the possible abnormalities such as line joining and line breaking of the return wire net 220.

[0100] In some embodiments, as shown in Figure 13 and Figure 14As shown, the guide rail 410 is provided with a plurality of connecting rods 420, i.e. the plurality of connecting rods 420 are arranged along the extension direction of the guide rail 410, and each connecting rod 420 is provided with a first data acquisition device 300. It is not difficult to understand that the plurality of first data acquisition devices 300 are distributed along the axial direction of the first fluted wheel 110, and thus the plurality of segments distributed in different regions of the return wire net 220 along the axis of the second fluted wheel 120 can be acquired. That is, the sampling object of each first data acquisition device 300 is part of the segments in the return wire net 220, and the sum of the sampling objects of all first data acquisition devices 300 includes all segments in the return wire net 220.

[0101] In the embodiment in which the plurality of connecting rods 420 are arranged on the guide rail 410, the connecting rod 420 and the guide rail 410 can be fixedly arranged or arranged with adjustable relative positions. In the embodiment in which the connecting rod 420 and the guide rail 410 are arranged with adjustable relative positions, the position of the connecting rod 420 on the guide rail 410 can be conveniently adjusted, and thus the position of the first data acquisition device 300 is changed to sample the segments distributed in different regions of the return wire net 220 along the axis of the second fluted wheel 120; further, the connecting rod 420 and the guide rail 410 can be connected by a locking device to relatively fix the connecting rod 420 and the guide rail 410. The locking device can be a set screw arranged on the connecting rod 420. In the embodiment in which the connecting rod 420 and the guide rail 410 are fixedly arranged, the connecting rod 420 and the guide rail 410 can be fixed by existing devices such as threaded fasteners, or other existing devices; in addition, the connecting rod 420 and the guide rail 410 can be an integral structure to fix the connecting rod 420 and the guide rail 410, and the specific way can be to weld or other ways to connect the connecting rod 420 and the guide rail 410 into an integral structure, or the connecting rod 420 and the guide rail 410 can be an integral structure in the process of machining.

[0102] In the above-mentioned embodiments, the sampling range is changed by the relative sliding of the connecting rod 420 and the guide rail 410 in the first mounting bracket 400, or the rotation of the data acquisition end of the first data acquisition device 300.

[0103] In some other embodiments, the position of the data collection end of the first data collection device 300 is changed by the relative movement between the first mounting frame 400 and the machine body, so as to adjust the collection range of the first data collection device 300 on the return wire net 220. For example, in some embodiments, the guide rail 410 in the first mounting frame 400 is movably connected to the machine body, and the movement includes translation towards or away from the return wire net 220, or rotation of the guide rail 410 about an axis, so as to rotate the data collection end of the first data collection device 300 in a vertical plane. Further, the movement range of the first mounting frame 400 satisfies that the collection range of the first data collection device 300 covers all segments of the cutting line in the return wire net 220. The first data collection device 300 is arranged on the guide rail 410 through the connecting rod 420, so as to move with the guide rail 410 and change the collection range of the first data collection device 300.

[0104] Similarly, in the case that the guide rail 410 is movably connected to the machine body, in some embodiments, a connecting rod 420 connected with the first data collection device 300 is arranged on the guide rail 410, and the connecting rod 420 is slidably arranged on the guide rail 410, and the sliding direction is parallel to the extension direction of the guide rail 410. In this embodiment, the position of the first data collection device 300 can also be changed by sliding the connecting rod 420, and further, a driving device can be arranged to drive the connecting rod 420 to move relative to the guide rail 410.

[0105] Similarly, in the case that the guide rail 410 is movably connected to the machine body, the first data collection device 300 can also be rotatably connected to the connecting rod 420, so as to rotate the data collection end in a vertical plane. This embodiment can be applied to the case that multiple connecting rods 420 connected with the first data collection device 300 are arranged on the guide rail 410, and in this embodiment, each data collection end can be adjusted individually.

[0106] In some embodiments, as shown in Figure 10 the data collection end of the first data collection device 300 includes a signal transmitting window 312, and a water baffle 440 is arranged above the signal transmitting window 312. Wherein, the water baffle 440 is arranged above the signal transmitting window 312 in the working state of the first data collection device 300, so as to at least partially block the liquid falling from above, and avoid the liquid falling on the signal transmitting window 312 and affecting the authenticity and accuracy of data collection.

[0107] Further, as shown in Figure 10In the shown embodiment, the first mounting frame 400 further comprises a base 430 for connecting the driving device with the guide rail 410, the splash guard 440 arranged on the base 430, and the connecting rod 420 arranged on the base 430. The splash guard 440 comprises a first section 441 and a second section 442 connected with each other, wherein the first section 441 is connected with the base 430 and the second section 442 is arranged horizontally. The sensor 310 in the first data acquisition device 300 comprises a housing 311 for connecting the connecting rod 420, a signal transmitter, a signal receiver, an antenna, a signal processing unit, a data processing unit and the like arranged inside the housing 311. The signal transmitter and the signal receiver are arranged towards the signal transmission and reception window 312. The signal transmission and reception window 312 is arranged on the housing 311 for the signal transmitter to transmit signals outwardly, and the signal transmission and reception window 312 is arranged towards the direction away from the first section 441 of the splash guard 440 and towards the side where the groove wheel assembly 100 is arranged; the second section 442 of the splash guard 440 is arranged above the signal transmission and reception window 312. The position of the signal transmission and reception window 312 in the housing 311 is further provided with a glass, and a relatively closed environment is formed between the glass and the housing 311 to avoid liquid entering the inside of the housing 311. In the sampling process, the signals of the sensor 310 pass through the glass; the splash guard 440 arranged above the glass can reduce the liquid falling on the glass from above.

[0108] Further, the connection between the first data acquisition device 300 and the connecting rod 420 is realized through the housing 311, as shown in Figure 10 Further, the connection between the first data acquisition device 300 and the connecting rod 420 is realized through the mutual connection between the housing 311 and the second part 422 of the connecting rod 420. Further, the second part 422 and the housing 311 are fixedly connected, such as screw fastening, or welding, or other connection modes.

[0109] In the above embodiment, by collecting data of the return wire net 220 through the first data acquisition device 300, the parallel lines and broken lines in the return wire net 220 can be monitored.

[0110] In some embodiments, as shown in Figure 15 and Figure 16As shown, the cutting device 100 further comprises a second data acquisition device 600, which can be connected to the machine body through a second mounting bracket. The second data acquisition device 600 is used to acquire data from above the cutting wire net 210, and the data acquisition end of the second data acquisition device 600 and the data acquisition end of the first data acquisition device 300 are respectively arranged on the two sides of the cutting wire net 210. That is, the data acquisition end of the second data acquisition device 600 is located above the cutting wire net 210 in the vertical direction, and therefore, the data acquired by the second data acquisition device 600 can be used to monitor abnormal conditions such as broken wires, parallel wires and jumper wires in the cutting wire net 210. The specific implementation of the second data acquisition device 600 for monitoring abnormal conditions such as broken wires, parallel wires and jumper wires in the cutting wire net 210 can be referred to the technical solutions disclosed in Chinese patents with publication numbers CN117665790A and CN117656268A. Further, in the present embodiment, the structure and installation method of the second data acquisition device 600 can be consistent with the monitoring mechanism in the Chinese patents with publication numbers CN117665790A and CN117656268A; the structure of the second data acquisition device 600 can also be consistent with the structure of the first data acquisition device 300 in the above embodiment, and the difference between the two is only the installation position.

[0111] During the cutting process, the segments of the cutting wire located in the return wire net 220 will move to the position of the cutting workpiece 700. If the segments in the return wire net 220 have abnormal conditions, it will cause abnormalities in the cutting wire net 210. Therefore, the data acquired by the first data acquisition device 300 can not only monitor the possible parallel wires and broken wires in the return wire net 220, but also can give an early warning of possible abnormal conditions in the cutting wire net 210, so as to handle the abnormal conditions in the cutting wire net 210 before they occur, which can greatly reduce the situation that the product obtained by cutting the workpiece 700 is unqualified due to the abnormal conditions in the cutting wire net 210.

[0112] Further, in some embodiments, on the horizontal direction, the two sides of the installation position (i.e. the clamping device) of the workpiece to be cut are provided with the first data acquisition device 300 and the second data acquisition device 600. Figure 15 As shown in the embodiment, the two second data acquisition devices 600 respectively acquire data from the part of the cutting wire net 210 passing through the cutting position and the part not passing through the cutting position; and the two first data acquisition devices 300 respectively acquire data from the first sub-wire net 221 and the second sub-wire net 222.

[0113] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
