Technical Field

[0001] The present invention relates to the technical field of multi-wire saw equipment, and in particular to a cutting device and a multi-wire saw equipment. Background Art

[0002] Multi-wire saws utilize multiple parallel cutting wires for cutting. Widely used in the photovoltaic, semiconductor, and stone processing industries, they are primarily used for cutting hard and brittle materials. The stability of the wire tension directly impacts the slicing quality and wire breakage rate of the multi-wire saw.

[0003] Existing multi-wire saw equipment mainly adjusts the tension of all cutting wires at the same time by pushing the guide wheel through the cylinder. Since there are certain differences in the usage wear and tear of each cutting wire, this method has problems such as single-wire tension imbalance and instantaneous tension fluctuations that cannot be corrected in real time during operation, and low accuracy of single-wire tension adjustment, which leads to poor stability of the cutting wire tension, resulting in poor slicing quality of the multi-wire saw equipment and a high cutting wire breakage rate. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a cutting device and a multi-wire saw equipment to solve the technical problems that the stability of the existing cutting wire tension is poor, resulting in poor slicing quality of the multi-wire saw equipment and a high cutting wire breakage rate.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The present invention provides a cutting device, comprising a driving wheel, a driven wheel group, a cutting line and a tensioning adjustment structure, wherein the cutting line is wound between the driving wheel, the driven wheel group and the tensioning adjustment structure, and the tensioning adjustment structure is located between the driving wheel and the driven wheel group.

[0007] The tension adjustment structure includes a tensioning member, a guide wheel connected to the tensioning member, a sensor, and a hinge point. The tension adjustment structure is hingedly fixed via the hinge point. The cutting line is wound around the guide wheel. The sensor is used to detect the stress state of the cutting line. The tensioning member adjusts the position of the guide wheel based on the stress state feedback from the sensor to adjust the tension of the cutting line. There are multiple cutting lines and tension adjustment structures, and each cutting line is provided in a one-to-one correspondence with the tension adjustment structure.

[0008] In a possible implementation, the plurality of tension adjustment structures are staggered along a first direction or a second direction, and the first direction and the second direction are perpendicular to each other.

[0009] The present invention further provides a multi-wire saw device comprising a base, a drive device, and the aforementioned cutting device. The driving wheel, the driven wheel assembly, the tensioning adjustment structure, and the drive device are all disposed on the base, and the drive device is in transmission connection with the driving wheel to drive the driving wheel to rotate.

[0010] In a possible implementation, the multi-wire saw device further includes a feeding platform provided on the base, the feeding platform being used to place the material to be cut, and a running direction of the feeding platform is perpendicular to a cutting direction of the cutting wire.

[0011] In one possible implementation, the driven wheel group includes at least three driven guide wheels, the cutting line is wound between the driving wheel and the three driven guide wheels, the driving wheel and the three driven guide wheels are distributed in a rectangular array, and the cutting line in the area between two adjacent driven guide wheels is used for cutting materials.

[0012] In a possible implementation, the driving device includes a driving motor and a driving synchronous belt, and the driving motor and the driving wheel are connected to each other through the driving synchronous belt.

[0021] The current tensioning technology of multi-wire saw equipment mainly uses a cylinder to provide tensioning force. The cylinder pushes the guide wheel to tension all diamond wires at the same time. In actual production and use, there are the following problems:

[0022] (1) Insufficient tension uniformity: The imbalance of single-wire tension caused by wear, temperature change or size difference of the diamond wire itself cannot be corrected in real time, resulting in uneven slice thickness or surface microcracks.

[0023] (2) Poor dynamic response capability: Traditional mechanical or group-type adjustments are difficult to match the instantaneous tension fluctuations during high-speed cutting, and the wire breakage rate remains high.

[0024] (3) Low level of intelligence: There is a lack of a closed-loop feedback mechanism for single-line tension, and adjustments rely on manual experience, making it difficult to continuously improve the cutting life, and the condition of the sand wire cannot be quantified.

[0025] In order to solve the above technical problems, the present invention provides a cutting device and a multi-wire saw device with a tension adjustment structure. The technical solutions and embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0027] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0029] like Figure 1 and Figure 2 As shown, the present invention provides a cutting device 1, including a driving wheel 11, a driven wheel group 12, a cutting line 13 and a tensioning adjustment structure 14, the cutting line 13 is wound between the driving wheel 11, the driven wheel group 12 and the tensioning adjustment structure 14, and the tensioning adjustment structure 14 is located between the driving wheel 11 and the driven wheel group 12.

[0030] The tensioning adjustment structure 14 includes a tensioning member 141, a guide wheel 142 connected to the tensioning member 141, a sensor 143, and a hinge point 144. The tensioning adjustment structure 14 is hinged and fixed via the hinge point 144. The cutting line 13 is wound around the guide wheel 142. The sensor 143 is used to detect the stress state of the cutting line 13. The tensioning member 141 adjusts the position of the guide wheel 142 based on the stress state feedback from the sensor 143 to adjust the tension of the cutting line 13. There are multiple cutting lines 13 and tensioning adjustment structures 14, and each cutting line 13 and tensioning adjustment structure 14 is provided in a one-to-one correspondence.

[0031] By setting a tensioning adjustment structure 14 on each cutting line 13, the sensor 143 in the tensioning adjustment structure 14 is used to monitor the stress state of the cutting line 13 in real time, and the tensioning member 141 is driven to adjust the position of the guide wheel 142 according to the feedback data of the sensor 143 to adjust the tension of each cutting line 13 to an appropriate state; or the operator is guided to replace the damaged cutting line 13 in time according to the feedback data of the sensor 143, thereby improving the stability of the tension of each cutting line 13, thereby improving the slicing quality of the cutting device 1 and even the multi-wire saw equipment 2, and reducing the wire breakage rate of the cutting line 13, so as to solve the technical problem that the stability of the tension of the existing cutting line 13 is poor, resulting in poor slicing quality of the multi-wire saw equipment 2 and a high wire breakage rate of the cutting line 13.

[0032] When the cutting line 13 becomes worn or loose after prolonged use, the tension adjustment mechanism 14 automatically adjusts the position of the guide wheel 142 based on feedback from the sensor 143 to maintain the tension of the cutting line 13 within an appropriate range. If the tension of the cutting line 13 exceeds the preset range, the data fed back by the sensor 143 will prompt the operator to inspect and perform maintenance.

[0033] Generally speaking, the cutting wire 13 is made of steel wire rope or diamond rope. Under the premise of not affecting the performance of the cutting wire 13, the present application does not limit the specific material of the cutting wire 13.

[0034] In an optional embodiment, the plurality of tension adjustment structures 14 are staggered along the first direction or the second direction, and the first direction and the second direction are perpendicular to each other.

[0035] The staggered arrangement of the tensioning adjustment structures 14 can allow the multiple tensioning adjustment structures 14 to retain a certain working space, avoiding mutual interference between the multiple tensioning adjustment structures 14 during operation, thereby enabling the tensioning adjustment structures 14 to maintain good working stability and adjustment accuracy during operation.

[0036] Specifically, the staggered arrangement direction of the plurality of tensioning adjustment structures 14 is parallel or perpendicular to the cutting direction of the cutting line 13 , that is, it can be considered that the first direction is parallel to the cutting direction of the cutting line 13 , and the second direction is perpendicular to the cutting direction of the cutting line 13 .

[0037] See Figure 2 and Figure 3 When the staggered arrangement is parallel to the cutting direction of the cutting line 13, two adjacent tension adjustment structures 14 are staggered a certain distance in the cutting direction, forming a plum blossom arrangement. This arrangement is suitable for long-distance cutting and can provide more uniform tension control in the running direction of the cutting line 13.

[0038] When the staggered arrangement is perpendicular to the cutting direction of the cutting line 13, the two adjacent tension adjustment structures 14 are staggered a certain distance in the direction perpendicular to the cutting direction, also forming a plum blossom arrangement. This arrangement is suitable for cutting wide materials and can provide more uniform tension control across the width of the material.

[0039] Furthermore, in practical applications, the staggered arrangement of the tensioning adjustment structures 14 facilitates operators to observe and adjust the working status of each tensioning adjustment structure 14 , thereby improving maintenance efficiency.

[0040] In an optional embodiment, the tensioning member 141 is any one of a spring, a cylinder and a weight.

[0041] Specifically, when the tensioning member 141 adopts a spring structure, the elastic coefficient of the spring can be selected according to the tensioning requirement of the cutting line 13. The position of the guide wheel 142 is adjusted by the expansion and contraction of the spring, thereby changing the tension of the cutting line 13.

[0042] Specifically, when tensioning member 141 is a pneumatic cylinder, the piston rod of the cylinder is connected to guide wheel 142. By controlling the air intake and exhaust of the cylinder, the position of the piston rod is adjusted, thereby changing the position of guide wheel 142 and adjusting the tension of cutting line 13. The advantages of pneumatic cylinders are high force, high adjustment accuracy, and remote control. They are suitable for large-scale cutting equipment or applications requiring precise tension control.

[0043] Specifically, when tensioning member 141 is a weight, the appropriate weight is selected based on the required tension of cutting line 13. The weight is connected to guide wheel 142 via a pulley system, leveraging gravity to adjust the position of guide wheel 142, thereby varying the tension of cutting line 13. The advantages of a weight are its simple structure, stability, and reliability, as well as its independence from external energy sources, making it suitable for cutting equipment operating in harsh environments.

[0044] like Figure 3 As shown, the present invention further provides a multi-wire saw device 2, comprising a base 21, a drive device 22, and the aforementioned cutting device 1. The driving wheel 11, the driven wheel assembly 12, the tensioning adjustment structure 14, and the drive device 22 are all disposed on the base 21. The drive device 22 is in transmission connection with the driving wheel 11 to drive the driving wheel 11 to rotate.

[0045] The base 21 not only provides installation space for various components of the multi-wire saw device 2, but also provides a stable working environment for the multi-wire saw device 2, so that the multi-wire saw device 2 can maintain good working stability.

[0046] In an alternative embodiment, Figure 3 As shown, the multi-wire saw device 2 further includes a feeding platform 23 disposed on the base 21. The feeding platform 23 is used to place the material to be cut. The running direction of the feeding platform 23 is perpendicular to the cutting direction of the cutting wire 13. Specifically, the feeding platform 23 can be composed of a platform for placing the material to be cut and a motor for driving the platform to reciprocate.

[0047] The arrangement in which the running direction of the feeding platform 23 and the cutting direction of the cutting line 13 are perpendicular to each other can enable the cutting line 13 to cut into the material to be cut relatively perpendicularly, thereby improving the cutting accuracy and cutting effect of the cutting line 13.

[0048] In an optional embodiment, the driven wheel group 12 includes at least three driven guide wheels 121, and the cutting line 13 is wound between the driving wheel 11 and the three driven guide wheels 121. The driving wheel 11 and the three driven guide wheels 121 are distributed in a rectangular array, and the cutting line 13 in the area between two adjacent driven guide wheels 121 is used for cutting materials.

[0049] The cutting line 13 is wound between the driving pulley 11 and three driven guide pulleys 121, forming a closed motion loop. The area between two adjacent driven guide pulleys 121 is used to cut material, and this area is called the cutting zone. Depending on the arrangement of the driven guide pulleys 121, multiple cutting zones can be formed, improving cutting efficiency.

[0050] During operation, the drive mechanism 22 rotates the driving wheel 11, which in turn drives the cutting line 13 through friction. The cutting line 13 then passes over three driven guide wheels 121, forming a closed motion loop. The material to be cut is fed into the cutting area via the feed platform 23, where it is cut into the desired shape by the high-speed motion of the cutting line 13.

[0051] The rectangular array design allows the cutting line 13 to cut in multiple directions, adapting to the cutting needs of materials of different shapes. At the same time, this design also makes it easier for operators to observe and adjust the cutting process, thereby improving work efficiency.

[0052] In addition, in actual production applications, the distance between the driving wheel 11 and the three driven guide wheels 121 can be accurately calculated to ensure that the cutting line 13 maintains appropriate tension and direction during operation.

[0053] In an optional embodiment, the surfaces of the driving wheel 11 and the driven guide wheel 121 are provided with anti-slip grooves and guide grooves, and the cutting line 13 is arranged in the guide groove to guide the running trajectory of the cutting line 13 to prevent the cutting line 13 from slipping and deviating during operation.

[0054] Compared with other transmission methods, such as chain transmission, belt synchronous transmission has the advantages of more compact structure, higher transmission accuracy and convenient maintenance, so that other components of the multi-wire saw equipment 2 can have more space for reasonable layout and improve the processing accuracy of the multi-wire saw equipment.

[0055] In an alternative embodiment, the multi-wire saw device 2 may utilize a PLC-controlled control system equipped with a touchscreen human-machine interface, through which the operator can set cutting parameters such as cutting speed and cutting depth. The control system also includes fault diagnosis and alarm functions. When an abnormality occurs in the device, an alarm will be issued and fault information will be displayed, allowing the operator to promptly address the problem.

[0056] The above description is merely a preferred embodiment of the present invention, and the above specific embodiment is not intended to limit the present invention. Various variations and modifications are possible within the technical scope of the present invention. Any modifications, alterations, or equivalent substitutions made by a person skilled in the art based on the above description are within the scope of protection of the present invention.
