Description

Technical Field

[0001] The present application relates to the technical field of film tearing equipment, and in particular to a film tearing machine. Background Art

[0002] As the core process equipment in the field of precision manufacturing, the film tearing machine has become an important technical equipment to support the upgrading of modern industry.

[0003] In the field of electronic product manufacturing, as smart terminal devices continue to evolve towards ultra-thinness and high integration, the thin film separation process of microelectronic components and flexible circuit substrates faces nano-level precision challenges. Taking mobile terminal chips as an example, the thickness of the surface covering film is very thin, and the peeling operation needs to achieve extremely small precision tolerances, which has a decisive impact on the yield rate and long-term reliability of the chip.

[0004] In the manufacturing of optical devices, the surface treatment of precision optical components must achieve atomic-level cleanliness standards. During the demolding process of the core lens group of professional imaging equipment, even if nano-level surface defects occur, it may cause the light path scattering coefficient to increase, directly affecting the imaging resolution and optical transfer function value. In the field of intelligent transportation equipment, the film removal process of the vehicle display module is directly related to the user interface touch sensitivity and transmittance indicators. The HUD display system of high-end models requires that the surface roughness after the film layer is removed must be controlled within a very small range.

The dielectric layer stripping operation in the wafer manufacturing process needs to be carried out in a Class 100 clean environment, and the dust particle control standard must reach ISO Class 5. Any residual particles exceeding the standard will cause the integrated circuit to fail.

[0034] Please refer to Figures 1 to 7 The embodiment of the present application provides a film tearing machine to realize automatic film tearing. The film tearing machine includes a protective shell 4, a conveying device, a film rubbing device and a film lifting device, and the conveying device, the film rubbing device and the film lifting device are arranged in the protective shell 4.

[0035] Specifically, the product 48 is horizontally placed on the conveying device for conveying, and the film rubbing device and the film lifting device are symmetrically arranged on both sides of the conveying device to tear the film of the product 48. The conveying device includes a frame 49, a push-in conveying mechanism 50 and a push-out conveying mechanism 62, and the push-in conveying mechanism 50 is provided with a feeding station 39 and a film lifting station 40, and the push-out conveying mechanism 62 is provided with a delivery station 41. The push-in conveying mechanism 50 includes a push-in component 51 and a pressure plate positioning component 52, the push-in component 51 is rotatably arranged on the frame 49, and the pressure plate positioning component 52 is movably arranged above the push-in component 51; the push-out conveying mechanism 62 includes a push-out component 63 and a moving component 64, the structure of the push-out component 63 is the same as that of the push-in component 51, and the push-out component 63 is arranged on the moving component 64.

[0036] Here, the product 48 is placed horizontally on the frame 49 of the conveying device, and the pushing component 51 of the pushing conveying mechanism 50 is rotated to convey the product 48 to the feeding station 39 and the film lifting station 40 in sequence. In this process, the film rubbing devices located on both sides of the conveying device perform film rubbing operations on the product 48 at the feeding station 39, and the film lifting device performs film tearing operations on the product 48 at the film lifting station 40. After the film tearing is completed, the pushing component 63 of the pushing conveying mechanism 62 moves the product 48 from the film lifting station 40 to the sending station 41 of the pushing conveying mechanism 62, completing the entire film tearing process. With the cooperation of the moving component 64 and the pushing component 63, the moving component 64 can move the pushing component 63 to other locations away from the film tearing machine so that the operator can remove the product 48 on the pushing component 63. The film tearing machine realizes the automated operation of film tearing of product 48 through the coordinated cooperation of the protective shell 4, the conveying device, the film rubbing device and the film lifting device, improves the efficiency and accuracy of film tearing, reduces the cost and error of manual operation, and the reasonable structural design of each part ensures the stability and smoothness of the film tearing process.

[0037] Please refer to Figure 2 and Figure 3 In a specific embodiment, the push-in assembly 51 includes a first driving member 53, a driving roller 54, a conveyor belt 55 and a plurality of rotating rollers 56. The first driving member 53 is fixed to one side of the frame 49, the driving roller 54 is rotatably arranged on the frame 49 along the conveying direction of the product 48, the conveyor belt 55 is rotatably connected to the output end of the first driving member 53 and the driving roller 54, and a plurality of first magnetic wheels 57 are arranged at intervals on the driving roller 54; the rotating rollers 56 are arranged at equal intervals on the frame 49 along the conveying direction perpendicular to the product 48, and a second magnetic wheel 58 is arranged at one end of each rotating roller 56 close to the driving roller 54, and the second magnetic wheel 58 is located directly above the first magnetic wheel 57.

[0038] In this regard, the first driving member 53 is fixed on one side of the frame 49 as a power source to provide power for the operation of the entire push-in assembly 51. The driving roller 54 is rotatably arranged on one side of the frame 49 along the conveying direction of the product 48, and is rotatably connected to the output end of the first driving member 53 through a conveyor belt 55, and can be rotated under the drive of the first driving member 53. At the same time, a plurality of first magnetic wheels 57 arranged at intervals on the driving roller 54 are used to cooperate with the second magnetic wheel 58 at one end of the rotating roller 56, and indirectly drive the rotating roller 56 through the magnetic effect. The product 48 is placed horizontally on the rotating roller 56, and the rotation of the rotating roller 56 can drive the product 48 to move, realize the transportation of the product 48 on the push-in assembly 51, and accurately transport the product 48 to the feeding station 39 and the film lifting station 40 in sequence.

[0039] Furthermore, at least three electrostatic wheels 59 are evenly spaced on each rotating roller 56. In other embodiments, four or five electrostatic wheels 59 may be provided. In this embodiment, the rotating roller 56 and the product 48 can only be in point contact, and the product 48 cannot be conveyed by a surface contact method such as a conveyor belt. The point contact conveying method can accurately contact a specific position of the product 48 sheet, apply a small and uniform force, and thus minimize the risk of damage to the product 48.

[0040] In addition, the electrostatic wheel 59 can generate static electricity, and utilize the principle of electrostatic adsorption to place the product 48 more firmly on the rotating roller 56, which can effectively prevent the product 48 from sliding or shaking on the rotating roller 56, ensuring that the product 48 can be accurately transported to the feeding station 39 and the film lifting station 40, thereby improving the stability and positioning accuracy of the product 48. In addition, during the production and processing of the product 48, static electricity may accumulate on the surface of the product 48, which may have an adverse effect on the quality of the product 48, such as adsorbing dust and causing electronic component failures. The electrostatic wheel 59 can conduct away the static electricity on the surface of the product 48, play a role in static electricity elimination, protect the product 48 from the harm of static electricity, and improve the quality and yield rate of the product 48.

[0041] In a specific embodiment, the platen positioning assembly 52 is disposed at one end of the feeding station 39 close to the film lifting station 40. The platen positioning assembly 52 includes a second driving member 60 and a pressing roller 61. The second driving member 60 is disposed on both sides of the frame 49, and both ends of the pressing roller 61 are rotatably connected to the vertical driving ends of the two sets of second driving members 60, and three electrostatic wheels 59 are disposed on the pressing roller 61 at equal intervals.

[0042] When the product 48 is pushed into the component 51 and transported to the end of the feeding station 39 near the film lifting station 40, the pressure roller 61 is pressed down by the second driving member 60, and cooperates with the rotating roller 56 to press the upper and lower sides of the product 48, so that it remains fixed in this position, ensuring that the product 48 will not move or shake during the film rubbing operation, thereby ensuring the accuracy and stability of the film rubbing. At the same time, the second driving member 60 can flexibly adjust the pressure of the pressure roller 61 on the product 48 according to the thickness or material characteristics of different products 48, so that the film tearing machine can adapt to the film tearing needs of various types of products 48, improving the versatility and applicability of the equipment.

[0043] In a specific embodiment, the moving assembly 64 includes a third driving member 65, a guide rail 66 and a base 67. The guide rail 66 is arranged along a direction perpendicular to the conveying direction of the product 48. In other embodiments, the guide rail 66 can also be arranged along other directions according to actual conditions; the horizontal driving end of the third driving member 65 is connected to the base 67, the base 67 is slidably connected to the guide rail 66, and the ejection assembly 63 is arranged on the base 67. In this embodiment, the third driving member 65 is a linear module.

[0044] In this regard, the base 67 can slide along the guide rail 66 under the drive of the third driving member 65, so as to realize the overall movement of the ejection assembly 63. Through the movement of the base 67, the ejection assembly 63 can be brought to different positions to meet the needs of the film tearing machine at different working stages. For example, when necessary, the ejection assembly 63 is moved back to the position docking with the film lifting station 40 to receive the product 48 after the film is peeled off, or moved to a position away from the film lifting station 40 so that the operator can remove the product 48, thereby improving the automation and convenience of the entire film tearing process.

[0045] Please refer to Figure 4 and Figure 5 In a specific embodiment, the film rubbing device is arranged between the feeding station 39 and the film lifting station 40, and the film rubbing device includes a film rubbing plate mechanism 6 and two sets of film rubbing mechanisms 5. The two sets of film rubbing mechanisms 5 are symmetrically fixed on both sides of the frame 49, and the film rubbing plate mechanism 6 is arranged between the two sets of film rubbing mechanisms 5. The film rubbing plate mechanism 6 is provided with a film rubbing clamping member 47 for clamping the edge of the product 48, and the film rubbing mechanism 5 is symmetrically provided with two sets of film rubbing wheels 45 along the vertical direction, and the film rubbing wheels 45 are used to roll on the film at the two corners of the upper and lower sides of the product 48.

[0046] Specifically, the film rubbing plate mechanism 6 includes two groups of eighth drive components 46 and film rubbing clamps 47 arranged in the vertical direction. The eighth drive component 46 is fixed on the conveying device, and the film rubbing clamp 47 is fixedly connected to the vertical drive end of the eighth drive component 46 to clamp the edge of the product 48. The film rubbing mechanism 5 also includes a fixed plate 42, a sixth drive component 43 and a seventh drive component 44. Among them, the fixed plate 42 is fixedly connected to one side of the conveying device, and the horizontal drive end of the sixth drive component 43 is symmetrically provided with two groups of seventh drive components 44 in the vertical direction, and the film rubbing wheel 45 is rotatably connected to the vertical drive end of each group of the seventh drive component 44.

[0047] When the product 48 is transported by the conveying device to one end of the feeding station 39 near the film lifting station 40, the pressure roller 61 and the rotating roller 56 cooperate with each other to position the product 48. At the same time, the two groups of eighth drive components 46 respectively drive the two film rubbing clamps 47 to move toward each other to clamp the edge of the product 48, so that the product 48 remains stable during the film rubbing process. Subsequently, the sixth drive component 43 drives the two groups of seventh drive components 44 symmetrically arranged along the vertical direction to move horizontally toward the direction of the product 48. The two groups of seventh drive components 44 respectively drive the film rubbing wheel 45 to move vertically, so that the film rubbing wheel 45 approaches and contacts the film at the two corners of the upper and lower sides of the product 48. Then the film rubbing wheel 45 starts to roll back and forth on the film, and uses the rolling friction to rub the film at the corners of the product 48 to prepare for the subsequent film lifting. After the film rubbing operation is completed, the eighth drive component 46 drives the film rubbing clamps 47 to move in opposite directions to release the product 48, and the product 48 continues to be transported to the film lifting station 40.

[0048] In this regard, the film rubbing plate mechanism 6 can firmly clamp the edge of the product 48 during the film rubbing process to prevent the product 48 from moving or shaking, ensure the smooth film rubbing operation, and improve the quality and effect of film rubbing. The film rubbing mechanism 5 rubs the film corners in advance to reduce the adhesion between the film and the product 48, making the subsequent film lifting operation easier and smoother, and effectively improving the film tearing efficiency. At the same time, the rolling film rubbing method of the film rubbing wheel 45 causes little damage to the film and the product 48, and can better protect the integrity of the product 48 and the film, ensuring the quality of the product 48.

[0049] Please refer to Figures 6 to 8 In a specific embodiment, the film lifting device includes a film lifting pressure plate mechanism 2, a film lifting mechanism 1 and a film grabbing mechanism. The film lifting pressure plate mechanism 2 is arranged between the pushing conveying mechanism 50 and the pushing conveying mechanism 62. The film lifting pressure plate mechanism 2 is provided with a clamping component 23 for clamping the edge of the product 48; the film lifting mechanism 1 is arranged on both sides of the film lifting pressure plate mechanism 2, and the film lifting mechanism 1 includes two groups of symmetrically arranged film lifting components 10, each group of film lifting components 10 respectively adheres to and lifts the film at the two corners of the upper and lower sides of the product 48; the film grabbing mechanism 3 is arranged on one side of the film lifting station 40, and the film grabbing mechanism 3 includes two groups of film grabbing components 30 respectively arranged above and below the film lifting station 40, and the film grabbing component 30 clamps the film lifted by the film lifting component 10 and drives the film to move in the opposite direction of the product 48 conveying.

[0050] Please refer to Figure 6Specifically, the film-lifting plate mechanism 2 also includes a first driving assembly 26. The first driving assembly 26 includes a first motor 27 and a first moving member 28. The first motor 27 is fixed on the conveying device at the delivery station 41. The first moving member 28 is fixed at the horizontal driving end of the first motor 27. The first motor 27 can drive the first moving member 28 to move in the direction of the delivery station 39, and the first moving member 28 penetrates a plate gap 29 for the product 48 to pass through. The clamping assembly 23 includes two groups of clamping motors 24 and film-lifting clamps 25 symmetrically arranged in the vertical direction. The two clamping motors 24 are respectively fixed on the upper side and the lower side of the plate gap 29, and the vertical driving ends of the clamping motors 24 are respectively connected to the film-lifting clamps 25 to drive the two film-lifting clamps 25 to move toward each other to clamp the edge of the product 48, or to move in opposite directions to release the product 48.

[0051] The product 48 is transported to the end of the film-lifting station 40 near the delivery station 41 by the conveying device, and the first motor 27 drives the first moving member 28 to move in the direction of the product 48. The two clamping motors 24 on the upper and lower sides of the plate gap 29 respectively drive the connected film-lifting clamping members 25 to move toward each other, thereby clamping the uncoated area of ​​the edge of the product 48 to position the product 48, facilitate the film-lifting mechanism 1 to lift the film, and improve the accuracy and efficiency of film lifting. After the two groups of film-lifting assemblies 10 lift the film from the corners of the product 48, the two clamping motors 24 drive the two film-lifting clamping members 25 to move in opposite directions to release the product 48, and the conveying device continues to transport the product 48, and the product 48 enters the delivery station 41 from the plate gap 29 of the first moving member 28.

[0052] Please refer to Figure 7 The film lifting mechanism 1 also includes a line slot frame 16, a second drive assembly 17 and a third drive assembly 20. The line slot frame 16 is symmetrically arranged on both sides of the film lifting plate mechanism 2. Among them, the second drive assembly 17 is symmetrically arranged on the two line slot frames 16, each group of the second drive assembly 17 includes a second motor 18 and a second moving member 19, the second motor 18 is fixed on the line slot frame 16, the second moving member 19 is fixed on the horizontal driving end of the second motor 18, and the second motor 18 is used to drive the second moving member 19 to approach the film lifting station 40. Two groups of third drive assemblies 20 are symmetrically arranged on each group of second moving members 19 in the vertical direction, and the third drive assembly 20 includes a third motor 21 and a third moving member 22. The third moving member 22 is fixed on the vertical driving end of the third motor 21, and the film lifting assembly 10 is arranged on the third moving member 22. The two third motors 21 are used to drive the two third moving members 22 to approach each other, so that the film lifting assembly 10 lifts the film at the upper and lower corners of the product 48.

[0053] The second motor 18 drives the second moving member 19 to approach the film lifting station 40, so that the second moving member 19 drives the third drive assembly 20 and the film lifting assembly 10 thereon to approach the product 48. When the second moving member 19 arrives at the set position, the two third motors 21 respectively drive the two third moving members 22 to approach each other, so that the film lifting assembly 10 arranged on the third moving member 22 adheres and lifts the film at the upper and lower corners of the product 48. After the film is lifted, the second moving member 19 and the third moving member 22 reset themselves respectively. Through the cooperation of the second drive assembly 17 and the third drive assembly 20, the movement of the film lifting assembly 10 in the horizontal and vertical directions can be realized, and the position of the film lifting assembly 10 can be accurately adjusted so that it can accurately reach the corner of the product 48 to perform the film lifting operation, thereby improving the accuracy of the film lifting.

The film 13 is fixed on the unwinding disk 11, and the movable end of the film 13 is rotatably connected to the film lifting wheel 14 and the tensioning wheel 15 in turn, and the movable end of the film 13 is fixed to the winding disk 12.

[0055] When the third motor 21 drives the third moving part 22 to make the film lifting assembly 10 approach the corner of the product 48, the active end of the film 13 is maintained in a certain tension state through the tensioning action of the tensioning wheel 15. When the film lifting wheel 14 contacts the film at the corner of the product 48, the film 13 on the film lifting wheel 14 adheres to the film. At this time, the winding disk 12 rotates to rewind the active end of the film 13, thereby pulling the film 13 and driving the tensioning wheel 15 and the film lifting wheel 14 to rotate, so that the film 13 drives the adhered film to be lifted. As the winding disk 12 continues to rotate, the film is continuously lifted until the film near one end of the film lifting plate mechanism 2 is completely lifted, which is convenient for the subsequent film grasping mechanism 3 to lift the film.

[0056] In this regard, the cooperation of the unwinding reel 11, the winding reel 12, the film 13, the film lifting wheel 14 and the tensioning wheel 15 can realize the continuous supply and winding of the film 13, ensure the continuity of the film lifting process, and improve the film lifting efficiency. The setting of the tensioning wheel 15 can keep the film 13 in a suitable tension, prevent the film 13 from being loose or too tight, ensure that the film 13 can stably adhere and lift the film, and improve the reliability and stability of the film lifting.

[0057] Please refer to Figure 8 The film grasping mechanism 3 also includes a first linear module 34, a moving frame 35, a second linear module 36, a fourth driving assembly 37 and a fifth driving assembly 38. Among them, the first linear module 34 is fixed to one side of the conveying device of the film lifting station 40, and the horizontal driving end of the first linear module 34 along the conveying path of the product 48 is connected to the moving frame 35. The moving frame 35 is symmetrically provided with two groups of second linear modules 36 along the vertical direction, and the horizontal driving end of each group of second linear modules 36 is connected to the fourth driving assembly 37, the vertical driving end of the fourth driving assembly 37 is connected to the fifth driving assembly 38, and the vertical driving end of the fifth driving assembly 38 is connected to the film grasping assembly 30. In this embodiment, the fourth driving assembly 37 and the fifth driving assembly 38 are both motors.

[0058] When the film lifting operation is required, the first linear module 34 drives the moving frame 35 to move to the set position along the conveying path of the product 48, and then starts the second linear module 36 to drive the fourth driving assembly 37 to the set position. After that, the fourth driving assembly 37 can drive the fifth driving assembly 38 to move in the vertical direction, and the fifth driving assembly 38 can drive the film grabbing assembly 30 to move in the vertical direction to adjust the height of the two sets of film grabbing assemblies 30, so that the two sets of film grabbing assemblies 30 gradually approach the product 48, and finally achieve the clamping of the film lifted by the film lifting assembly 10, and drive the film to move in the opposite direction of the product 48 conveying, completing the film lifting action.

[0059] In this regard, through the cooperation of the first linear module 34, the second linear module 36, the fourth drive assembly 37 and the fifth drive assembly 38, the film grasping assembly 30 can be moved in multiple dimensions in the horizontal and vertical directions, and the position of the film grasping assembly 30 can be accurately adjusted so that the film can be grasped accurately, thereby improving the accuracy of grasping the film. The symmetrically arranged structural design can grasp the film on both the upper and lower sides of the product 48 at the same time, thereby improving work efficiency and reducing the time of grasping the film.

[0060] Furthermore, the film grasping assembly 30 includes a mounting frame 31, a cylinder 32 and a gripping clamp 33. The mounting frame 31 is fixed to the vertical driving end of the fifth driving assembly 38, and cylinders 32 are respectively arranged on both sides of the mounting frame 31 in the horizontal direction, and a gripping clamp 33 is respectively connected to the driving end of each cylinder 32, and the gripping clamp 33 is rotatably connected to the mounting frame 31.

[0061] When the fifth drive assembly 38 drives the mounting frame 31 to move to a set position close to the film, the film grabbing assembly 30 is in a state of preparing to grab the film. At this time, the two cylinders 32 start to work, and the driving ends of the cylinders 32 extend to push the two connected grippers 33 to rotate toward the direction of the product 48 until the grippers 33 clamp the film. When the film needs to be moved, the first linear module 34 drives the mounting frame 31 and the film clamped by the grippers 33 to move in the opposite direction of the product 48. The fourth drive assembly 37 and the fifth drive assembly 38 can drive the film to move in a direction away from the product 48 to provide sufficient film lifting space and complete the film grabbing and moving operations.

[0062] In this regard, the combination of the mounting frame 31, the cylinder 32 and the gripper 33 can effectively grip the film, which is easy to manufacture, install and maintain. The gripper 33 is rotatably connected to the mounting frame 31, so that the gripper 33 can make certain adjustments according to the position and angle of the film when clamping the film, thereby improving the success rate of gripping the film. The two symmetrically arranged cylinders 32 and grippers 33 can clamp the film from both sides at the same time, ensuring a uniform clamping force on the film, avoiding the film from being offset or damaged during the gripping process, and is beneficial to protecting the film and the product 48.

[0063] In a specific embodiment, the film peeling machine further includes a visual positioning mechanism, which is arranged at the bottom of the film peeling station 40 to take pictures and locate the copper-retaining parts of the product 48. In the application scenario of the film peeling machine, "retaining copper" means that when film is applied or peeled off on a product 48 such as a circuit board, some copper parts on the circuit board are deliberately left uncovered by the film, or the integrity and functionality of these copper parts are ensured not to be affected during the film peeling process.

[0064] Here, the visual positioning mechanism uses a high-precision camera to take a picture of the product 48 on the film-lifting station 40, identifies the copper position on the product 48 where the film is not attached, and calculates the position deviation and angle deviation of the product 48 relative to the coordinate system of the film-lifting station 40, so as to adjust the position of the product 48, so that the film-lifting pressing plate mechanism 2 can accurately clamp the copper position on the product 48, avoiding accidental clamping of the area with film attached, which affects the subsequent film grabbing and tearing processes.

[0065] Please refer to Figure 5In a specific embodiment, the film tearing machine further includes a plurality of film blowing mechanisms 7, and the plurality of film blowing mechanisms 7 are equidistantly arranged on one side of the conveying mechanism 4 of the film lifting station 40. When the film grasping mechanism 3 successfully lifts the film on the product 48 and drives the film to move to a certain position, the film blowing mechanism 7 receives a work instruction and starts to start. The power device (such as a fan, etc.) inside the film blowing mechanism 7 generates an airflow, which is blown out from the air outlet. The film blowing mechanisms 7 equidistantly arranged simultaneously blow air to the lifted film, and the airflow acts on the film, causing the film to be subjected to an outward force. Under the continuous action of the airflow, the force exerted on the film is sufficient to overcome the slight adhesion between it and the film grasping mechanism 3 or other components and its own gravity, so that the film is detached from the film grasping mechanism 3 and blown off, completing the film blowing operation.

[0066] In this regard, the film blowing mechanism 7 can quickly and effectively blow off the film after the film grabbing mechanism 3 lifts up the film, which speeds up the separation process of the film from the product 48 and the film grabbing mechanism 3, improves the working efficiency of the entire film tearing machine, saves film tearing time, and is conducive to improving production efficiency. On the other hand, the film blowing off automation operation is further realized, reducing the manual participation in the film separation link, reducing labor costs and labor intensity, and also reducing problems such as product 48 damage or film residue caused by improper manual operation.

[0067] In a specific embodiment, residual film sensors 8 are respectively provided on the upper and lower sides of the film lifting station 40 near one end of the delivery station 41. The residual film sensor 8 can accurately sense the film on the upper and lower sides to detect whether the lifted film is damaged, so as to determine whether there is residual film left on the surface of the product 48. Regardless of the size and location of the damaged area, as long as it is within the sensing range of the residual film sensor 8, it can be discovered in time, which can prevent the product 48 with residual film from entering the next process, and prevent the residual film from affecting the subsequent processing and use of the product 48, such as avoiding residual film from causing appearance defects and performance of the product 48, thereby ensuring the overall quality of the product 48. When the residual film sensor 8 detects that the film is damaged, it can immediately trigger the corresponding processing mechanism, such as shutdown alarm, start the cleaning device, etc., which can quickly deal with the residual film problem, reduce delays and waste in the production process, and improve production efficiency.

[0068] Furthermore, plasma electrostatic rods 9 are respectively arranged on the upper and lower sides of the film-lifting station 40 near one end of the delivery station 41, and the plasma electrostatic rods 9 are arranged adjacent to the residual film sensor 8. The plasma electrostatic rods 9 can eliminate static electricity on the film, avoid residual film remaining on the surface of the product 48 due to electrostatic adsorption, and cooperate with the residual film sensor 8 to better detect whether there is residual film, thereby ensuring that the surface of the product 48 is clean after the film is torn off, and further ensuring the quality of the product 48 and the smooth progress of subsequent processing.

[0069] Please refer to Figure 1 and Figure 2 Furthermore, a waste film frame 68 is arranged below the push-in conveying mechanism 50, and rollers are arranged at the bottom of the waste film frame 68 to move the waste film frame 68. The waste film frame 68 is arranged below the push-in conveying mechanism 50 to facilitate the collection of waste film torn off and dropped from the product 48, to prevent waste film from being scattered around the equipment, and to keep the working environment clean. The operator only needs to process the waste film in the waste film frame 68 regularly, which improves the cleaning efficiency and reduces the difficulty and workload of the cleaning work. In addition, the waste film is prevented from entering other parts of the equipment or the operating parts of the conveying device, to avoid the normal operation of the equipment being affected by the entanglement or blockage of the waste film, to protect the equipment, to reduce the incidence of equipment failures, and to extend the service life of the equipment.

[0070] In a specific embodiment, the protective shell 4 is provided with a plurality of doors and windows 70 that can be opened and closed. When the film tearing machine needs to be maintained, serviced or troubleshooted, the operator can open the doors and windows 70 to conveniently enter the protective shell 4 to inspect, repair and replace the various components of the film tearing machine. The doors and windows 70 provide a convenient passage, and at the same time facilitate the removal and placement of the waste film frame 68, avoiding the inconvenience of operation caused by the closure of the protective shell 4, and improving the efficiency of maintenance work. During the operation of the equipment, the operator can observe the operation of the film tearing machine through the doors and windows 70, such as the transportation of the product 48, the process of film tearing, the operating status of each component, etc., and can promptly discover abnormal situations, such as the product 48 being stuck, the film tearing not being smooth, etc., so as to take timely measures to deal with them and ensure the normal operation of the equipment.

[0071] In a specific embodiment, an exhaust fan 69 is provided on the protective shell 4. During the operation of the film tearing machine, various components inside it, such as driving parts, motors, etc., will generate heat when working. Long-term accumulation may cause the internal temperature of the equipment to be too high, affecting the performance and service life of the equipment. The exhaust fan 69 can discharge the hot air in the protective shell 4, promote air circulation, reduce the internal temperature, and ensure that the equipment operates under a suitable temperature environment. During the film tearing process, some odors may be generated, such as the odor emitted by the film material, or the odor caused by friction, static electricity, etc., and some dust such as film debris may also be generated. The exhaust fan 69 can discharge these odors and dust out of the protective shell 4 in time, keep the working environment clean and hygienic, which is beneficial to the health of the operator, and can also reduce the impact of dust on the equipment, and prevent dust from entering the interior of the equipment and affecting the normal operation of the components.

[0072] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
