[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] In practical applications, traditional infrared broadband ultra-low reflection film shearing devices may not be able to easily change the shearing length of the infrared broadband ultra-low reflection film when faced with different shearing requirements, thus failing to meet the diverse needs of customers and resulting in a loss of market competitiveness.
[0022] In view of this, the present invention provides an infrared broadband ultra-low reflection film shearing device, which solves the problem that in actual use, traditional infrared broadband ultra-low reflection film shearing devices may not be able to easily change the shearing length of the infrared broadband ultra-low reflection film when faced with different shearing requirements, thus failing to meet the diverse needs of customers and resulting in a loss of market competitiveness.
[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0024] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0025] Example 1: As shown in Figures 1-4, an infrared broadband ultra-low reflection film cutting device includes an operating table 1. A through groove 11 is provided on the surface of the operating table 1. A first support 12 is fixedly connected to the top of the operating table 1. A hydraulic cylinder 121 is fixedly connected to the top of the inner wall of the first support 12. A cutter 122 is fixedly connected to the output end of the hydraulic cylinder 121. The infrared broadband ultra-low reflection film cutting device also includes a length fixing device 3, a deviation correction device 4, and a pressing device 5. The length fixing device 3 is located above the operating table 1. The deviation correction device 4 is installed on the surface of the operating table 1 through the through groove 11. The pressing device 5 is located on the side of the cutter 122. The length fixing device 3 is used to fix the length of the infrared broadband ultra-low reflection film and cut it with the cutter 122. The deviation correction device 4 prevents the infrared broadband ultra-low reflection film from shifting. The pressing device 5 presses and fixes the infrared broadband ultra-low reflection film.
[0026] In the specific implementation process, it is worth noting that the operating table 1 is a rectangular plate with a through groove 11 on one side of the center. The through groove 11 is a rectangular groove. The first support 12 is shaped like a "7". The model of the first hydraulic cylinder 121 is selected according to the specific design requirements, working parameters and load of the cutter 122 of the shearing device. The operator uses the length fixing device 3 to fix the length of the infrared wide-wave ultra-low reflection film, and then uses the cutter 122 to cut the infrared wide-wave ultra-low reflection film. The cutter 122 is fixed to the output end of the first hydraulic cylinder 121 by the cutter holder. A monitoring device can also be added to the cutter holder to monitor the cutting position of the cutter 122. When the infrared wide-wave ultra-low reflection film deviates, the correction device 4 is used to adjust the infrared wide-wave ultra-low reflection film. During shearing, the clamping device 5 is used to clamp and fix the infrared wide-wave ultra-low reflection film to prevent displacement of the infrared wide-wave ultra-low reflection film and affect the shearing.
[0027] Furthermore, a shearing table 2 is provided below the cutter 122. A limit plate 22 is fixedly connected to the top of the shearing table 2. A first photoelectric sensor 23 is fixedly connected to one side of the bottom of the shearing table 2. A support rod 21 is fixedly connected to the side of the bottom of the shearing table 2 away from the first photoelectric sensor 23. The support rod 21 is fixedly connected to the top of the operating table 1. The length fixing device 3 includes a second photoelectric sensor 31, a scale 32, a third vertical plate 33, a third photoelectric sensor 34, a vacuum roller 35, a second servo motor 36, and a vacuum pump 37. Two second photoelectric sensors 31 are provided, which are fixedly connected to the front and rear sides of the cutter 122 respectively. The scale 32 is machined on the front of the shearing table 2. Two third vertical plates 33 are provided, which are fixedly connected to the top of the operating table 1 away from the cutter 122 respectively. The front and rear sides; two third photoelectric sensors 34 are provided, respectively fixedly connected to the outer wall of the third vertical plate 33 on the side close to each other; the vacuum roller 35 is rotatably connected between the two third vertical plates 33 through a sealed bearing, and is located below the third photoelectric sensor 34; the output end of the second servo motor 36 is fixedly connected to the back of the vacuum roller 35, and the outer wall is fixedly connected to the top of the operating table 1; the input end of the vacuum pump 37 is connected to the end of the vacuum roller 35 away from the second servo motor 36, and the bottom is fixedly connected to the top of the operating table 1; wherein, through the second photoelectric sensor 31, scale 32, third photoelectric sensor 34, vacuum roller 35, second servo motor 36 and vacuum pump 37, in cooperation with the cutter 122, the infrared broadband ultra-low reflection film is cut to a fixed length;
[0028] In the specific implementation process, it is worth noting that the shearing table 2 is generally rectangular, with two limiting plates 22 having a trapezoidal cross-section. Each plate has connecting rods fixed to its front and rear sides at the bottom, which are then fixed to the front and rear side walls of the shearing table 2. The limiting plates 22 assist the cutter 122, ensuring its cutting position and preventing deviation. Two first photoelectric sensors 23 are located on the front and rear sides of the bottom of the shearing table 2, used in conjunction with the subsequent correction device 4. The model of the first photoelectric sensor 23 needs to be selected appropriately according to the specific requirements of the infrared broadband ultra-low reflection film shearing device; for example, LTH can be selected. The -301-3 type 15mm groove photoelectric sensor can be used in infrared broadband ultra-low reflection film shearing devices for precise control of the shearing length. The support rod 21 supports the shearing table 2, improving shearing stability. The second photoelectric sensor 31 and the third photoelectric sensor 34 can be of the same model, with two of each. The second photoelectric sensor 31 is installed on the front and rear sides of the top blade holder of the cutter 122, and the third photoelectric sensor 34 is installed on the opposite side of the outer wall of the third vertical plate 33. Both sensors monitor whether the film material has reached directly below them. The operator can visually observe the length of the sheared film material through the scale 32. It is understood that shorter shearing is required... When cutting the membrane material, it can be cut according to the scale 32. When the required length exceeds the maximum distance of the scale 32, the third photoelectric sensor 34 receives a signal, coordinating with the subsequent operation of the vacuum roller 35. The two ends of the vacuum roller 35 are respectively connected to the second servo motor 36 and the vacuum pump 37. The output shaft of the second servo motor 36 and the vacuum roller 35 are generally connected by a coupling. The coupling can compensate for the installation error between the two shafts, transmit torque, and ensure that the power of the second servo motor 36 can be efficiently and stably transmitted to the vacuum roller 35. The model of the second servo motor 36 is selected according to actual needs, as long as it meets the working requirements. For example, in the 1FK7042-5AF71-1TGO model, the connection method between the vacuum pump 37 and the vacuum roller 35 is usually determined by the type and size of the air inlet of the vacuum pump 37 and the vacuum interface on the vacuum roller 35. If both are hose nozzle connectors and are the same size, a vacuum rubber hose of the corresponding size can be purchased directly for connection. If the sizes are different, a hose nozzle diameter adapter needs to be added for conversion. The operator uses the second photoelectric sensor 31, scale 32, third photoelectric sensor 34, vacuum roller 35, second servo motor 36, and vacuum pump 37 in conjunction with the cutter 122 to improve the cutting flexibility of the infrared broadband ultra-low reflection film shearing device.
[0029] Furthermore, a controller 13 is fixedly connected to the top of the operating table 1 near the vacuum pump 37, and a loading roller 14 is provided on the top of the operating table 1 away from the vacuum roller 35. The front and rear of the loading roller 14 are rotatably connected to a first vertical plate 141 through sealed bearings. The bottom of the first vertical plate 141 is fixedly connected to the top of the operating table 1. A first servo motor 142 is fixedly connected to the front of the loading roller 14. The first servo motor 142 is fixedly connected to the top of the operating table 1. Support legs 18 are fixedly connected to the four corners of the bottom of the operating table 1.
[0030] In the specific implementation process, it is worth noting that the specific model of controller 13 can be selected according to actual needs, as long as it meets the operational requirements. For example, a servo controller of model 6SL3040-1MAO1-OAAO can be selected. The loading roller 14 is used to store the uncut film material. Two first upright plates 141 are provided, which support the loading roller 14. The model of the first servo motor 142 is selected according to actual needs, as long as it meets the operational requirements. For example, the same 1FK7042-5AF71-1TGO as the second servo motor 36 can be selected. The first servo motor 142 and the controller... The specific connection method of controller 13 is as follows: First, connect controller 13 to a three-phase AC power supply, ensuring the phase sequence is correct. Connect the power module to controller 13. The power module has clear power input terminal markings, such as L1, L2, and L3. Connect the corresponding three-phase power lines to these terminals and connect a 24V DC power supply to power the control circuit of controller 13. Then, connect the power cable of the first servo motor 142 to the corresponding power module output terminal of controller 13. The 1FK7042-5AF71-1TGO motor has an encoder for feedback of the motor's position and speed information. First, the encoder cable connects to the encoder interface of controller 13, typically an X401 interface. This interface allows controller 13 to obtain the motor's operating status in real time, thereby achieving precise closed-loop control. When connecting, pay attention to the plug orientation and pin correspondence to avoid incorrect connections. Second, controller 13 connects to the host computer (such as a PLC) via a Profinet network cable. The X20 interface of controller 13 is a Profinet interface. Insert one end of the network cable into this interface and connect the other end to the corresponding network port on the PLC. This enables data communication and control command transmission. The PLC can send bit... The controller 13 sends control commands such as setting and speed to the controller 13, which then controls the servo motor to run according to the commands. External input and output signals, such as start, stop, and alarm signals, are connected through the digital input and output interface of the controller 13. The connection method of the second servo motor 36 is the same as that of the first servo motor 142. It can be understood that if the controller 13 does not have enough terminals, an external terminal block can be connected for auxiliary connection. The support leg 18 provides support for the entire infrared wide-wave ultra-low reflection film shearing device. Through the cooperation of the above-mentioned parts, the operational stability of the infrared wide-wave ultra-low reflection film shearing device is improved.
[0031] Specifically, when a shorter piece of film needs to be cut, before cutting, the operator wraps the film around the carrier roller 14 and connects the external power supply to the controller 13, starting the controller 13. The controller 13 then starts the first servo motor 142, which drives the carrier roller 14 to rotate, causing the film on the carrier roller 14 to leave the carrier roller 14. The operator manually assists in moving the film, placing one side of the film on the top of the shearing table 2, passing through the limiting plate 22 directly below the cutter 122. At this time, the second photoelectric sensor 31 detects the passage of the film. After determining the required length of the film through the scale 32, the first servo motor 142 is stopped, and the hydraulic cylinder 121 is started through the controller 13. The hydraulic cylinder 121 drives the cutter 122 to move. The cutter 122 passes through the limiting plate 22 and contacts the surface of the film, cutting the film. After cutting, the controller 13 and the hydraulic cylinder 121 work together to drive the cutter 122 back to its original position. When the required length of the film is much longer than the scale 32, The operator places one side of the membrane material on the top of the shearing table 2, passing it through the limiting plate 22 directly below the cutter 122. At this time, the second photoelectric sensor 31 detects the membrane material passing by, and the operator moves the membrane material further until it passes the third photoelectric sensor 34. At this time, the controller 13 connects the external power supply of the second servo motor 36 and the vacuum pump 37. The vacuum pump 37 creates a negative pressure on the surface of the vacuum roller 35, adsorbing the membrane material. The second servo motor 36 drives the vacuum roller 35 to rotate at a constant speed, causing the membrane material to wrap around the top of the vacuum roller 35. After reaching the specified length, the second servo motor 36 stops, and then the membrane material is cut in the same way as described above, controlled by the hydraulic cylinder 121 to cut the membrane material with the cutter 122. It can be understood that the diameter of the vacuum roller 35 is known, and the circumference can be determined by calculation. Alternatively, a vacuum roller 35 with the required diameter can be directly customized to facilitate the calculation of the membrane material length. The operator can know the length of the membrane material by the number of wrapping turns and the scale 32, with a small error.
[0032] Example 2: As shown in Figures 1-4, the correction device 4 includes a third servo motor 41, a threaded rod 42, a correction seat 43, a correction frame 44, and a correction roller 45. The third servo motor 41 is fixedly connected to the outer wall of the operating table 1 near the first servo motor 142. The threaded rod 42 is rotatably connected to the inner wall of the through groove 11 via a sealed bearing, with one end extending to the outside of the operating table 1 and fixedly connected to the output end of the third servo motor 41. The correction seat 43 is threadedly connected to the outer wall of the threaded rod 42 and fits against the inner wall of the through groove 11. The correction frame 44 is fixedly connected to the top of the correction seat 43. The correction roller 45 is rotatably connected to the inner wall of the correction frame 44 via a sealed bearing. The third servo motor 41, the threaded rod 42, the correction seat 43, the correction frame 44, and the correction roller 45 play a correction role for the infrared broadband ultra-low reflection film passing through the correction roller 45.
[0033] In the specific implementation process, it is worth noting that the model of the third servo motor 41 can be selected according to actual needs, as long as it meets the working requirements. For example, the same 1FK7042-5AF71-1TGO servo motor as the first servo motor 142 can be selected. The connection method with the controller 13 is the same as that of the first servo motor 142. The third servo motor 41 provides power to the threaded rod 42, the threaded rod 42 transmits power to the correction seat 43, the correction seat 43 supports the correction frame 44, and the correction frame 44 is shaped like a 'U' and supports the correction roller 45. In use, the correction roller 45 applies lateral force to the deviated film material through the cooperation of the third servo motor 41, the threaded rod 42, the correction seat 43, the correction frame 44 and the correction roller 45, so that it returns to the correct conveying path, thereby improving the cutting accuracy of the infrared wide-wave ultra-low reflection film shearing device.
[0034] Furthermore, a second support 15 is fixedly connected to the top of the operating table 1 on the side of the first support 12 away from the third upright plate 33, and a third support 16 is fixedly connected to the top of the operating table 1 on the other side of the first support 12. The clamping device 5 includes a first telescopic rod 51, a clamping rod 52, a second telescopic rod 53, and a clamping plate 54. The first telescopic rod 51 is fixedly connected to the top of the inner wall of the second support 15; the clamping rod 52 is fixedly connected to the output end of the first telescopic rod 51; the second telescopic rod 53 is fixedly connected to the top of the inner wall of the third support 16; and the clamping plate 54 is fixedly connected to the output end of the second telescopic rod 53. The cooperation of the first telescopic rod 51, the clamping rod 52, the second telescopic rod 53, and the clamping plate 54 keeps the infrared broadband ultra-low reflection film being sheared stationary.
[0035] In the specific implementation process, it is worth noting that the second support 15 and the third support 16 are the same as the first support 12, forming a '7' shape. When viewed from the front, the three have different widths and heights. The second support 15 and the third support 16 have the same height. The first telescopic rod 51 and the second telescopic rod 53 are both electric telescopic rods. The specific model is selected according to actual needs to meet the load capacity, stroke requirements, and speed requirements of the infrared wide-wave ultra-low reflection film shearing device. The clamping rod 52 is generally rectangular in shape, and the clamping plate 54 is rectangular in shape. The width of the clamping plate 54 is the same as the length of the scale 32. The clamping rod 52 and the clamping plate 54 are used together to prevent the film material from tilting upward or shifting due to force during the cutting process, ensuring that the cutting edge is neat and accurate. Through the cooperation of the first telescopic rod 51, the clamping rod 52, the second telescopic rod 53, and the clamping plate 54, the operator has further improved the cutting accuracy of the infrared wide-wave ultra-low reflection film shearing device.
[0036] Furthermore, two second vertical plates 17 are provided between the top shearing table 2 and the correction frame 44. The bottoms of the two second vertical plates 17 are fixedly connected to the front and rear of the top of the operating table 1, respectively. Two auxiliary rollers 171 are rotatably connected between the two second vertical plates 17 through sealed bearings.
[0037] In the specific implementation process, it is worth noting that there are two second vertical plates 17, which are arranged opposite each other and support the auxiliary rollers 171. There are two auxiliary rollers 171, which are arranged vertically. The auxiliary rollers 171 play a supporting and guiding role in the film material conveying process. The auxiliary rollers 171 can reduce the friction between the film material and the surface of the shearing table 2, making the film material conveying smoother. At the same time, they play a certain guiding role for the film material. The auxiliary correction device 4 ensures that the film material is conveyed to the shearing area along the correct path, thereby further improving the working efficiency and shearing quality of the infrared broadband ultra-low reflection film shearing device.
[0038] Specifically, firstly, when the first photoelectric sensor 23 on the infrared broadband ultra-low reflection film shearing device detects a shift in the film material, it transmits an electrical signal to the controller 13. After observing the signal on the controller 13, the operator connects the external power supply to the third servo motor 41 through the controller 13, starting the third servo motor 41. The third servo motor 41 drives the threaded rod 42 to rotate, the threaded rod 42 drives the correction seat 43 to move, the correction seat 43 drives the correction frame 44 to move, the correction frame 44 drives the correction roller 45 to move, and the correction roller 45 drives the film material on its surface to move, achieving lateral fine adjustment of the film material. The first photoelectric sensor 23 receives the signal and transmits it to the controller 13, which stops the third servo motor 41, and the correction work is completed. Secondly, when shearing the film material, the operator manually moves the film material directly under the cutter 122. After determining the length, the membrane material needs to be fixed. The operator connects the external power supply of the first telescopic rod 51 and the second telescopic rod 53 through the controller 13, starts the first telescopic rod 51, and the first telescopic rod 51 drives the pressing rod 52 to move downward, so that the pressing rod 52 presses one side of the membrane material. At the same time, the second telescopic rod 53 is started, and the second telescopic rod 53 drives the pressing plate 54 to move downward until the pressing plate 54 presses the membrane material and fixes it. After the cutting is completed, the second telescopic rod 53 drives the pressing plate 54 to move upward, so that the pressing plate 54 leaves the surface of the membrane material. The operator removes the membrane material. When the next cutting is required, the operator holds the membrane material and starts the first telescopic rod 51. The first telescopic rod 51 drives the pressing rod 52 to move upward. The operator continues to pull out a sufficient length of membrane material, and repeats the starting and stopping of the first telescopic rod 51 and the second telescopic rod 53.
