[0050] Figure 1 FIG. 1 shows a schematic structural diagram of a film cutting device in an embodiment of the present application. Figure 2 The structure diagram of the membrane cutting assembly in one embodiment of the present application is shown. Figure 3 A schematic structural diagram of a clamping assembly in an embodiment of the present application is shown.

[0051] See also Figure 1-Figure 3 An embodiment of the present application provides a film cutting device 10 , including a first driving mechanism 100 , a second driving mechanism 200 , a film cutting assembly 300 and a clamping assembly 400 .

[0052] The film cutting assembly 300 and the clamping assembly 400 are located on opposite sides of the stacked material along the first direction F1. The film cutting assembly 300 can be used to cut the film on one side of the stacked material along the first direction F1, and the clamping assembly 400 can be used to clamp the film on the other side of the stacked material along the first direction F1.

[0053] The first driving mechanism 100 is connected to the film cutting assembly 300 to drive the film cutting assembly 300 to move along the first direction F1 toward the side close to the clamping assembly 400. The film cutting assembly 300 is used to cut the film on the stacked material to form an incision on one side of the film along the first direction F1.

[0054] The second driving mechanism 200 is connected to the clamping assembly 400 to drive the clamping assembly 400 to move along the first direction F1 toward the side close to the film cutting assembly 300. The clamping assembly 400 is used to clamp the film with the cut.

[0055] Therefore, when the film cutting device 10 of the present application is used, the first drive mechanism 100 can first be used to drive the film cutting assembly 300 to move along the first direction F1 toward the side close to the clamping assembly 400, so that the film cutting assembly 300 moves along the first direction F1 toward the stacked material. Then, the film cutting assembly 300 can be used to cut the film on the stacked material along the first direction F1, so that the film cutting assembly 300 cuts the film on the stacked material and forms an incision on the side of the film along the first direction F1. The second drive mechanism 200 can then be used to drive the clamping assembly 400 to move along the first direction F1 toward the side close to the film cutting assembly 300 and toward the stacked material. The clamping assembly 400 can then be used to clamp the incision. The second drive mechanism 200 can then be used to drive the clamping assembly 400 to move along the first direction F1 away from the film cutting assembly 300 so that the film can be discarded and collected at a designated location. In this way, the film cutting device 10 can achieve automated film cutting, saving manpower, reducing labor costs, and improving film cutting efficiency.

[0056] Optionally, the film cutting device 10 further includes a first frame 500, on which the first drive mechanism 100 and the second drive mechanism 200 are respectively disposed, so that the first drive mechanism 100 and the second drive mechanism 200 can be moved as a whole by the first frame 500. Specifically, the first frame 500 is a horizontally disposed frame.

[0057] In some embodiments, see Figure 4 The first drive mechanism 100 includes a first motor 110 mounted on the first frame 500, a first transmission belt (not shown) connected to the first motor 110, and a first connector 120 connected to the first transmission belt. The first connector 120 is connected to the film cutting assembly 300. Specifically, the first connector 120 is connected to the film cutting assembly 300 via a first support chain 130. More specifically, the first connector 120 is connected to the second frame 320 of the film cutting assembly 300 via the first support chain 130. Thus, the first motor 110 drives the first transmission belt, thereby driving the first connector 120 to move in the first direction F1, and thus driving the film cutting assembly 300 to move in the first direction F1.

[0058] Optionally, a first linear guide rail (not shown in the figures) is provided on the first frame 500 , and the first connecting member 120 is slidably connected to the first linear guide rail along the first direction F1 .

[0059] In some embodiments, please refer to Figure 4The second driving mechanism 200 includes a second motor 210 mounted on the first frame 500, a second transmission belt (not shown) connected to the second motor 210, and a second connecting member 220 connected to the second transmission belt. The second connecting member 220 is connected to the clamping assembly 400 via a second support chain 230. Specifically, the second support chain 230 is connected to the third frame 490 described below, and the clamping assembly 400 is mounted on the third frame 490. Thus, the second motor 210 is used to drive the second transmission belt, thereby driving the second connecting member 220 to move in the first direction F1, and further driving the clamping assembly 400 to move in the first direction F1.

[0060] Optionally, a second linear guide rail is provided on the first frame 500 , and the second connecting member 220 is slidably connected to the second linear guide rail along the first direction F1 .

[0061] In some embodiments, see Figure 2 , and refer to Figure 5 The film cutting assembly 300 includes a heating wire 310 extending along the second direction F2. The heating wire 310 is connected to the first driving mechanism 100 and is used to form an incision extending along the second direction F2 on the film.

[0062] The first direction F1 and the second direction F2 intersect each other. Optionally, the first direction F1 and the second direction F2 are perpendicular to each other. For example, the first direction F1 is parallel to the horizontal direction, and the second direction F2 is parallel to the gravity direction of the film cutting device 10 .

[0063] Specifically, the film cutting assembly 300 further includes a second frame 320 , the heating wire 310 is disposed on the second frame 320 , and the second frame 320 is connected to the first driving mechanism 100 .

[0064] In this way, the film can be heated by using the heating wire 310 extending along the second direction F2, and since the heating wire 310 is thinner than the hot air gun, it is equivalent to using the heating wire 310 to perform a heat cutting operation on the film, and the incision extending along the second direction F2 can be formed on the film more quickly, so that the clamping component 400 can clamp the film with the incision. In this way, the film cutting efficiency of the film cutting component 300 can be effectively improved.

[0065] In some embodiments, see Figure 5 The film cutting assembly 300 further includes at least two first suction cups 330 for adsorbing the film. The at least two first suction cups 330 are located on opposite sides of the heating wire 310 along the third direction F3 and are connected to the first driving mechanism 100. The first direction F1, the second direction F2, and the third direction F3 intersect with each other.

[0066] Optionally, the first direction F1 , the second direction F2 and the third direction F3 are perpendicular to each other. For example, the first direction F1 is the front-to-back direction, the second direction F2 is the up-down direction, and the third direction F3 is the left-to-right direction.

[0067] Since at least two first suction cups 330 are located on opposite sides of the heating wire 310 along the third direction F3, the at least two first suction cups 330 can be used to adsorb the film on both sides along the third direction F3, making it easier for the central heating wire 310 to cut the film.

[0068] Optionally, at least three first suction cups 330 are provided, and at least two first suction cups 330 located on the same side of the heating wire 310 along the third direction F3 are spaced apart along the second direction F2.

[0069] In this way, at least two first suction cups 330 spaced apart along the second direction F2 can adsorb the film on both sides along the second direction F2, and can better adsorb the top and bottom ends of the film along the second direction F2, making it easier for the heating wire 310 to form an incision extending along the second direction F2 on the film, which is more conducive to the clamping component 400 clamping the film with the incision.

[0070] The film cutting device 10 also includes a controller 600. The film cutting assembly 300 also includes a first detector 340. The first detector 340 is used to obtain a first contact signal indicating that the first suction cup 330 has contacted the film. The controller 600 is electrically connected to the first detector 340, the first drive mechanism 100, and the heating wire 310. When the first detector 340 obtains the first contact signal, the controller 600 controls the first drive mechanism 100 to stop driving the film cutting assembly 300 in the first direction F1 toward the side closer to the clamping assembly 400.

[0071] Optionally, the first detector 340 is a proximity switch.

[0072] Specifically, the first motor 110 of the first driving mechanism 100 is electrically connected to the controller 600 .

[0073] In this way, when the first driving mechanism 100 drives the film cutting assembly 300 to move along the first direction F1 toward the side close to the clamping assembly 400, when the first suction cup 330 contacts the film, the first detector 340 obtains a first contact signal. The controller 600 can control the first driving mechanism 100 to stop driving the film cutting assembly 300 to move along the first direction F1 toward the side close to the clamping assembly 400, and then use the first suction cup 330 to absorb the film. Then, the first driving mechanism 100 drives the film cutting assembly 300 to move along the first direction F1 toward the side away from the clamping assembly 400, driving the first suction cup 330 and the film absorbed by the first suction cup 330 to move along the first direction F1 toward the side away from the clamping assembly 400, so that the film is pulled outward slightly, so that the film of the stacked material is separated from the material, and then the film is cut by the heating wire 310. In this way, the heating wire 310 can be better utilized for the film cutting operation.

[0074] In some embodiments, please refer to Figure 2 and Figure 6 The film cutting assembly 300 also includes a first telescopic rod 350 corresponding to the first suction cup 330 one by one. The first telescopic rod 350 extends along the first direction F1. The side of the first suction cup 330 away from the clamping assembly 400 along the first direction F1 is connected to the first driving mechanism 100 through the corresponding first telescopic rod 350.

[0075] Optionally, the first telescopic rod 350 is specifically a spring buffer rod.

[0076] It can be understood that compared with the first suction cup 330, the first telescopic rod 350 is farther away from the film along the first direction F1, so that when the first suction cup 330 contacts the film, the first telescopic rod 350 can be compressed. Since there are at least two first suction cups 330, each first suction cup 330 is provided with a buffer stroke, which can be compatible with the situation where the surface of the stacked materials is uneven during transportation, so that multiple first suction cups 330 can suck the film, thereby improving the reliability of the film cutting device 10.

[0077] In this embodiment, the film cutting assembly 300 also includes a first detection target 360 provided on the first telescopic rod 350. The first detector 340 is opposite to and spaced apart from the first detection target 360 for sensing the first detection target 360. The first detector 340 is used to obtain a first contact signal when the first detection target 360 is not sensed.

[0078] Since the first detector 340 is used to sense the first detection target 360, when the first suction cup 330 contacts the film, it will drive the first telescopic rod 350 and the first detection target 360 to move along the first direction F1 toward the side away from the film, thereby causing the first detection target 360 to leave the detection range of the first detector 340, and then a first contact signal can be obtained. In this way, the first detector 340 can be better utilized to detect whether the first suction cup 330 contacts the film.

[0079] In some embodiments, the film cutting assembly 300 further includes a first pressure detector 370 disposed on one side of the first suction cup 330 . The first pressure detector 370 is used to detect the vacuum level of the first suction cup 330 .

[0080] The first pressure detector 370 can be used to detect the vacuum degree of the first suction cup 330, thereby determining whether the first suction cup 330 and the film are firmly adsorbed, thereby improving the reliability of the film cutting device 10. Figure 2 and Figure 5 The second frame 320 includes a first horizontal frame 321 and two first vertical frames 322. The first connecting member 120 is connected to the first horizontal frame 321 via a first support chain 130. The two first vertical frames 322 are arranged on the first horizontal frame 321 at intervals along the third direction F3. Each first vertical frame 322 is provided with at least two first suction cups 330 (each first suction cup 330 is correspondingly provided with a first telescopic rod 350 and a first detection target 360 disposed on the first telescopic rod 350), at least two first detectors 340 corresponding to the first suction cups 330, a first cylinder 331 in communication with the first suction cups 330 (the first cylinder 331 is used to maintain a negative pressure in the first suction cups 330 to adhere to the film), and a first pressure detector 370 for detecting the vacuum level of the at least two first suction cups 330. The heating wire 310 is provided on one of the first vertical frames 322, and the at least two first suction cups 330 can be positioned on opposite sides of the heating wire 310 along the third direction F3.

[0081] Thus, when the first motor 110 drives the first transmission belt, the first connecting member 120 is driven to move along the first direction F1, thereby driving the second frame 320 and the film cutting assembly 300 on the second frame 320 to move along the first direction F1.

[0082] Optionally, the film cutting assembly 300 further includes a mounting seat 341 , the first detector 340 is disposed on the mounting seat 341 , and the mounting seat 341 is connected to the corresponding first vertical frame 322 .

[0083] Optionally, the film cutting assembly 300 further includes a swing arm 311 and a swing arm seat 312 (eg Figure 10As shown in the figure), the swing arm seat 312 is provided on one of the first vertical frames 322 of the second frame 320, and the heating wire 310 is provided on the swing arm 311. The swing arm 311 is rotatably provided on the swing arm seat 312 around an axis parallel to the third direction F3. In this way, when the film is pulled outward a little and the film is cut by the heating wire 310, the rotatable swing arm 311 can allow the heating wire 310 to float to a certain extent, thereby achieving film cutting while avoiding the impact of the outward pulling force on the heating wire 310.

[0084] Optionally, the film cutting assembly 300 further includes a swing arm cylinder 313 connected to the swing arm base 312 to drive the swing arm base 312, the swing arm 311, and the heating wire 310 to move in the first direction F1. In this manner, the swing arm cylinder 313 can be used to drive the swing arm base 312, the swing arm 311, and the heating wire 310 to move in the first direction F1 as needed for the film cutting operation, thereby better utilizing the heating wire 310 for film cutting.

[0085] Optionally, a swing arm 311 is respectively provided at both ends of the swing arm seat 312, and each swing arm 311 is provided with a mounting shaft 314. One end of the heating wire 310 is wound around the mounting shaft 314 on the swing arm 311 at one end of the swing arm seat 312, and protrudes from the mounting shaft 314 along the radial direction of the mounting shaft 314. The other end of the heating wire 310 is wound around the mounting shaft 314 on the swing arm 311 at the other end of the swing arm seat 312, and protrudes from the mounting shaft 314 along the radial direction of the mounting shaft 314, so that the two ends of the heating wire 310 are respectively connected to an external power supply or heater, so that the heating wire 310 can be heated by the power supply or heater, and the film cutting operation can be performed using the heating wire 310.

[0086] In some embodiments, please refer to Figure 1 and Figure 4 The film cutting device 10 further includes a third drive mechanism 700, which is connected to the first drive mechanism 100 and the second drive mechanism 200, respectively, to drive the first drive mechanism 100 and the second drive mechanism 200 to rise and fall in the second direction F2. Specifically, the first drive mechanism 100 and the second drive mechanism 200 are respectively mounted on the first frame 500. The third drive mechanism 700 is used to drive the first frame 500 to rise and fall in the second direction F2, thereby driving the first drive mechanism 100 and the second drive mechanism 200 to rise and fall in the second direction F2. This facilitates adjustment of the height of the film cutting assembly 300 and the clamping assembly 400 in the second direction F2, thereby enabling film cutting operations at different heights using the film cutting assembly 300 and the clamping assembly 400.

[0087] In this embodiment, the film cutting device 10 also includes a controller 600, and the film cutting assembly 300 also includes a second detector 380, which is used to detect the first position signal of the film. The controller 600 is electrically connected to the second detector 380 and the third drive mechanism 700 respectively, so as to control the third drive mechanism 700 to stop driving the first drive mechanism 100 and the second drive mechanism 200 when the second detector 380 senses the first position signal.

[0088] Optionally, the third driving mechanism 700 includes a third motor 710, a third transmission belt 720, two transmission gears 730 arranged at intervals along the second direction F2, and a third connecting member 740, the output end of the third motor 710 is connected to one of the transmission gears 730, one end of the third transmission belt 720 is connected to the top of the third connecting member 740, the other end of the third transmission belt 720 passes around the two transmission gears 730 and is connected to the bottom end of the third connecting member 740, and the first frame 500 is connected to the third connecting member 740.

[0089] Specifically, the third motor 710 of the third driving mechanism 700 is electrically connected to the controller 600 .

[0090] In this way, when the third motor 710 is running, it can drive the two transmission gears 730 to rotate, and the two transmission gears 730 can drive the third transmission belt 720 to transmit, thereby driving the third connecting member 740 and the first frame 500 to rise and fall along the second direction F2, thereby driving the first driving mechanism 100 and the second driving mechanism 200 to rise and fall along the second direction F2, and can adjust the height of the film cutting assembly 300 and the clamping assembly 400 along the second direction F2.

[0091] Optionally, the film cutting device 10 also includes a fourth frame 750, the third motor 710 is arranged on the fourth frame 750, and the third connecting member 740 is slidably connected to the fourth frame 750 along the second direction F2, so that the third driving mechanism 700 can better drive the first driving mechanism 100 and the second driving mechanism 200 to rise and fall along the second direction F2.

[0092] Specifically, a third linear guide rail is provided on the fourth frame 750 , and the third connecting member 740 is slidably connected to the third linear guide rail along the second direction F2 .

[0093] Optionally, a lifting foot cup 751 is provided at the bottom of the fourth frame 750 to facilitate adjustment of the height of the fourth frame 750 along the second direction F2.

[0094] Optionally, the second detector 380 is a photoelectric sensor. Specifically, the second detector 380 is a KEYENCE color code photoelectric sensor.

[0095] Optionally, the second detector 380 may be disposed on one of the first vertical frames 322 .

[0096] The third driving mechanism 700 can drive the first driving mechanism 100 and the second driving mechanism 200 to move up and down along the second direction F2, and further drive the film cutting assembly 300 and the clamping assembly 400 to move up and down along the second direction F2. During the movement of the film cutting assembly 300 along the second direction F2, the second detector 380 will sense the material and film of the stacked material. Since the film is usually transparent and the material is usually non-transparent, the signal strength of the second detector 380 sensing the material and the signal strength of the second detector 380 sensing the film are significantly different. When the sensing signal strength of the second detector 380 changes to a certain extent, it can be determined that the film cutting assembly 300 has reached the film cutting station. At this time, the second detector 380 will obtain a first position signal, and the controller 600 can control the third driving mechanism 700 to stop driving the first driving mechanism 100 and the second driving mechanism 200, thereby enabling the film cutting assembly 300 to perform film cutting operations more accurately at the film cutting station, thereby improving the degree of automation and film cutting accuracy of the film cutting device 10.

[0097] In some embodiments, the film cutting assembly 300 further includes a third detector 390 . Optionally, the third detector 390 is disposed on the first horizontal frame 321 .

[0098] When the second detector 380 senses the first position signal, the third detector 390 is located on the top side of the palletized material along the second direction F2, and the third detector 390 is used to detect the second position signal of the palletized material. The controller 600 is electrically connected to the third detector 390 and the first drive mechanism 100, so that when the third detector 390 senses the second position signal, the controller 600 controls the first drive mechanism 100 to stop driving the film cutting assembly 300 along the first direction F1 toward the side closer to the clamping assembly 400.

[0099] Optionally, at least two third detectors 390 are provided, and the at least two third detectors 390 are arranged at intervals along the third direction F3, so that the at least two third detectors 390 can be used to detect two places on one side of the stacked material along the first direction F1, which can improve the accuracy of the third detector 390 in detecting the stacked material.

[0100] Optionally, the third detector 390 is a diffuse reflection photoelectric switch.

[0101] During the process of the first driving mechanism 100 driving the film cutting assembly 300 to move along the first direction F1 toward the side close to the clamping assembly 400, the third detector 390 can be moved above the stacked materials. When the third detector 390 located above the stacked materials detects the stacked materials downward, the third detector 390 is triggered and a second position signal can be obtained. At this time, the first driving mechanism 100 can be controlled to stop driving the film cutting assembly 300 to move along the first direction F1 toward the side close to the clamping assembly 400 to perform the film cutting operation.

[0102] In some embodiments, see Figure 7 and Figure 9 The clamping assembly 400 includes a fourth drive mechanism 410 and two clamping jaws 420. The fourth drive mechanism 410 is mounted on the second drive mechanism 200 and connected to the two clamping jaws 420 to drive the two clamping jaws 420 to switch between a released state and a clamped state. After the film cutting assembly 300 completes the film cutting operation, the fourth drive mechanism 410 drives the two clamping jaws 420 to switch from a released state to a clamped state, thereby allowing the two clamping jaws 420 to clamp the film with the cut.

[0103] In some embodiments, the clamping assembly 400 further includes a second suction cup 430 , and the second suction cup 430 is used to absorb the film along the first direction F1 away from the film cutting assembly 300 .

[0104] In this way, after the second suction cup 430 adsorbs the film along the first direction F1 away from the side of the film cutting assembly 300, the second driving mechanism 200 can drive the clamping assembly 400 to move along the first direction F1 toward the side away from the film cutting assembly 300, so that the film is pulled outward a little, making it convenient for the fourth driving mechanism 410 to drive the two clamping jaws 420 to clamp the film with the incision, and then continue to use the second driving mechanism 200 to drive the clamping assembly 400 to move along the first direction F1 toward the side away from the film cutting assembly 300, so that the film can be discarded and collected to a designated location.

[0105] In some embodiments, the clamping assembly 400 also includes a fourth detector 440, which is used to obtain a second contact signal when the second suction cup 430 contacts the film. The controller 600 is electrically connected to the fourth detector 440 and the second drive mechanism 200, respectively, so as to control the second drive mechanism 200 to stop driving the clamping assembly 400 to move along the first direction F1 toward the side away from the film cutting assembly 300 when the fourth detector 440 obtains the second contact signal and the clamping jaw 420 is in a released state.

[0106] Optionally, the fourth detector 440 is a proximity switch.

[0107] Specifically, the second motor 210 of the second driving mechanism 200 is electrically connected to the controller 600 .

[0108] The clamping jaws 420 are in a loose state. During the process in which the second driving mechanism 200 drives the clamping assembly 400 to move along the first direction F1 toward the side away from the film cutting assembly 300, when the fourth detector 440 senses the film, a second contact signal can be obtained. At this time, the controller 600 controls the second driving mechanism 200 to stop driving the clamping assembly 400 to move along the first direction F1 toward the side away from the film cutting assembly 300, and the second suction cup 430 can be used to adsorb the film along the first direction F1 away from the film cutting assembly 300, and then the second driving mechanism 200 drives the film to be pulled out a little, and then the two clamping jaws 420 clamp the film with the incision, and then the second driving mechanism 200 continues to drive the clamping assembly 400 to move along the first direction F1 toward the side away from the film cutting assembly 300, so as to discard the film and collect it to a designated location.

[0109] Optionally, two fourth driving mechanisms 410 are provided, and the two fourth driving mechanisms 410 are spaced apart along the third direction F3. Each fourth driving mechanism 410 is connected to two clamping jaws 420, which can improve the stability and reliability of film clamping.

[0110] Optionally, the fourth detector 440 operates in a similar manner to the first detector 340. Accordingly, the clamping assembly 400 further includes a second telescopic rod 450 corresponding to the second suction cup 430 and a second detection target 460 disposed on the second telescopic rod 450. The fourth detector 440 is configured to obtain a second contact signal when the second detection target 460 is not sensed. When the second suction cup 430 contacts the film, it moves the second telescopic rod 450 and the second detection target 460 in the first direction F1 away from the film, thereby causing the second detection target 460 to exit the detection range of the fourth detector 440. This allows the second contact signal to be obtained, thereby better detecting whether the second suction cup 430 is in contact with the film.

[0111] Optionally, the clamping assembly 400 further includes a second pressure detector 470 disposed on one side of the second suction cup 430.

[0112] The second pressure detector 470 is used to detect the vacuum degree of the second suction cup 430.

[0113] The second pressure detector 470 can be used to detect the vacuum level of the second suction cup 430 , thereby determining whether the second suction cup 430 is firmly adsorbed to the film, thereby improving the reliability of the film cutting device 10 .

[0114] The clamping jaw 420 includes a first articulated arm 421, a second articulated arm 422 and a clamping jaw body 423. The fourth driving mechanism 410 is hinged to one end of the first articulated arm 421, the other end of the first articulated arm 421 is hinged to one end of the second articulated arm 422, and the other end of the second articulated arm 422 is hinged to one end of the clamping jaw body 423. In this way, the fourth driving mechanism 410 is used to output power moving along the first direction F1 to drive the two clamping jaws 420 to switch between a released state and a clamped state.

[0115] Optionally, the fourth driving mechanism 410 is a cylinder, and the piston rod of the cylinder is telescopically arranged along the first direction F1.

[0116] In some embodiments, the clamping assembly 400 further includes a tension detector 480 , which is configured to detect the tension applied by the two clamping jaws 420 to the film in the clamping state.

[0117] Furthermore, the film cutting device 10 further includes a controller 600 and an alarm 800, and the controller 600 is electrically connected to the tension detector 480 and the alarm 800 respectively (eg Figure 8 As shown in FIG, the controller 600 is used to control the alarm 800 to send an alarm signal when the tension detected by the tension detector 480 is greater than a threshold value.

[0118] In the process of clamping the film with the incision by the two clamping jaws 420, the tension detector 480 can be used to monitor the tension applied to the film by the two clamping jaws 420. If the tension detected by the tension detector 480 is greater than the threshold value, it means that the tension applied to the film by the two clamping jaws 420 is too large. The alarm device 800 can be controlled to send an alarm signal, which is convenient for manual processing through the alarm signal. In this way, there is a protection mechanism for abnormal situations such as the film is not cut, the film is embedded in the material, etc.

[0119] Optionally, the film cutting device 10 also includes a third frame 490, the third frame 490 includes a second horizontal frame 491 and two second vertical frames 492, the above-mentioned second connecting member 220 is connected to the second horizontal frame 491 of the third frame 490, and the two second vertical frames 492 are arranged on the second horizontal frame 491 at intervals along the third direction F3. Each second vertical frame 492 is provided with a clamping assembly 400, which can enable the two fourth drive mechanisms 410 to be arranged at intervals along the third direction F3.

[0120] Thus, when the second motor 210 drives the second transmission belt, the second connecting member 220 is driven to move along the first direction F1, thereby driving the third frame 490 and the clamping assembly 400 on the third frame 490 to move along the first direction F1.

[0121] Optionally, the tension detector 480 includes a fixed part 481, a movable part 482 and a tension detection body (not shown in the figure), the fourth driving mechanism 410 and the two clamping jaws 420 are arranged on the movable part 482, the movable part 482 is movably connected to the fixed part 481 along the first direction F1, and the fixed part 481 is connected to the second driving mechanism 200. Specifically, the fixed part 481 is arranged on the corresponding second longitudinal frame 492.

[0122] In this way, the tension detecting body can detect the tension of the movable portion 482 relative to the fixed portion 481 along the first direction F1, and further detect the tension applied to the film by the two clamping jaws 420.

[0123] In summary, when the film cutting device 10 of the present application is used, the first driving mechanism 100 can be used to drive the film cutting assembly 300 to move along the first direction F1 toward the side close to the clamping assembly 400, so that the film cutting assembly 300 moves along the first direction F1 toward the stacked material. When the first detector 340 senses the film, the controller 600 can be used to control the first driving mechanism 100 to stop driving the film cutting assembly 300, and use the first suction cup 330 of the film cutting assembly 300 to absorb the stacked material along the first direction F1. Then, the first driving mechanism 100 drives the first suction cup 330 and the film absorbed by the first suction cup 330 to move along the first direction F1 toward the side away from the clamping assembly 400, so that the film is pulled outward a little. , and then use the heating wire 310 of the film cutting assembly 300 to perform the film cutting operation to form an incision extending along the second direction F2 on one side of the film along the first direction F1; then use the second driving mechanism 200 to drive the clamping assembly 400 to move along the first direction F1 toward the side close to the film cutting assembly 300 and move closer to the stacked material. When the fourth detector 440 senses that the film and the clamping claw 420 are in a loose state, the controller 600 controls the second driving mechanism 200 to stop driving the clamping assembly 400 to move along the first direction F1 toward the side away from the film cutting assembly 300, and the second suction cups 430 of the two clamping assemblies 400 can be used to adsorb the film along the first direction F1 away from the film cutting assembly 300 (can be combined with Figure 7 and Figure 9 To understand, at this point, along the first direction F1, the second suction cup 430 is closer to the film than the clamping jaws 420. The second drive mechanism 200 then pulls the film slightly outward, facilitating separation from the material (e.g., the box). The fourth drive mechanism 410 then drives the corresponding two clamping jaws 420 to clamp the cut film. The second drive mechanism 200 then drives the clamping assembly 400 to move along the first direction F1 away from the film cutting assembly 300, allowing the clamping jaws 420 to release the film and collect the discarded film at a designated location. In this way, the film cutting device 10 can achieve automated film cutting, saving manpower, reducing labor costs, and improving film cutting efficiency.
