Description

Technical Field

[0001] This application relates to the field of film-tearing equipment technology, specifically to a film-tearing device. Background Technology

[0002] In the assembly process of electronic products, it is often necessary to attach or assemble several small parts onto larger parts. To prevent damage to the small parts during handling or transfer, a protective film is usually attached to their surface to provide temporary protection. Before attaching or assembling the small parts onto the larger parts, the protective film must be removed. Currently, there are two common methods: robotic grippers and manual removal.

[0003] However, for small parts with weak structural strength (such as thin metal parts), using a robotic gripper for film tearing can easily lead to deformation due to excessive pulling force. Furthermore, the fixed tearing direction of the robotic gripper during the tearing process makes tearing difficult, and for some structurally weak film parts, traditional robotic grippers can easily damage the film during tearing, leaving film residue on the workpiece. While manual film tearing can reduce the probability of damage to small parts to some extent, it suffers from high labor intensity, low efficiency, and poor operational consistency. In addition, manual operation is susceptible to fatigue and experience level, making it difficult to meet the needs of large-scale automated production. Therefore, a more efficient, stable film tearing solution that causes less damage to small parts is urgently needed. Utility Model Content

[0004] In view of the above, it is necessary to propose a film-tearing device that can automatically adjust the film-tearing direction during the film-tearing process, so as to solve the problems of workpiece or film damage, low work efficiency and inconsistent film-tearing effect caused by the film-tearing process.

[0005] This application provides a film-tearing device for tearing film from a workpiece, comprising: a support frame with a material carrier plate for supporting and positioning the workpiece, the material carrier plate having a clearance groove corresponding to the film, the clearance groove being used to avoid obstructing the film; a translation component connected to the support frame; and a film-folding component including a sliding seat, a transverse sliding plate, a longitudinal sliding plate, a first elastic element, and a second elastic element. The sliding seat is connected to the translation component, the transverse sliding plate is slidably connected horizontally to the side of the sliding seat opposite to the translation component, the longitudinal sliding plate is slidably connected vertically to the side of the transverse sliding plate opposite to the sliding seat, and the two ends of the first elastic element are respectively connected to the sliding seat and the transverse sliding plate. The system includes a sliding plate, a first elastic member for pulling the transverse sliding plate along the horizontal direction towards the carrier plate after being stretched, a second elastic member with its two ends connected to the transverse sliding plate and the longitudinal sliding plate respectively, and the second elastic member for pulling the longitudinal sliding plate along the vertical direction towards the carrier plate after being stretched; a lifting assembly including a lifting drive and a lifting member connected to the lifting drive, the lifting drive being connected to the sliding seat, and the lifting member also being inclinedly and slidably connected to the longitudinal sliding plate in the direction toward the carrier plate; and a clamping assembly connected to the side of the longitudinal sliding plate away from the lifting member and disposed close to the carrier plate, the clamping assembly being used to clamp the membrane.

[0006] The aforementioned film-tearing device supports and positions the workpiece via a carrier plate on a support frame. The carrier plate has recessed slots for avoiding misalignment of the film. When the workpiece is placed on the carrier plate, the film corresponds to the recessed slots, facilitating separation of the film from the workpiece. During film tearing, the translation component moves the film-folding component, lifting component, and clamping component horizontally towards the carrier plate. The lifting drive of the lifting component drives the lifting member to move vertically, thereby pushing against the longitudinal sliding plate of the film-folding component and the clamping component connected to the longitudinal sliding plate, moving vertically towards the carrier plate. Since the longitudinal sliding plate and the lifting member are slidably connected towards the carrier plate, while the lifting drive drives the lifting member to rise vertically, the longitudinal sliding plate slides relative to the lifting member and moves closer to it, and then moves horizontally away from the carrier plate relative to the lifting member. The longitudinal sliding plate also drives the transverse sliding plate to move horizontally away from the carrier plate relative to the lifting member. At this time, the transverse sliding plate stretches the first elastic element, and the longitudinal sliding plate stretches the second elastic element. When the clamping assembly moves to the position corresponding to the film under the driving action of the translation and lifting assemblies, the clamping assembly clamps the film. Then, the lifting drive drives the lifting member to retract, and the first elastic element pulls the transverse sliding plate to move horizontally toward the carrier plate, thereby driving the longitudinal sliding plate and the clamping assembly to move horizontally toward the carrier plate. The second elastic element pulls the longitudinal sliding plate to move vertically away from the lifting member, thereby driving the clamping assembly to continue moving toward the workpiece to bend the film head of the film, making the film head of the film tilted relative to the workpiece. Next, the translation assembly drives the film bending assembly, lifting assembly, and clamping assembly to move horizontally away from the carrier plate, and the lifting drive drives the longitudinal sliding plate and clamping assembly to move vertically away from the carrier plate through the lifting member. After bending the film head of the film, the clamping assembly tears the film off the workpiece in an inclined tearing manner. The aforementioned film-tearing device can automatically adjust the film-tearing direction during film tearing, first tilting the film head relative to the workpiece, and then tearing off the film. This can effectively avoid damage to the workpiece or film caused by film tearing, resulting in high work efficiency and high consistency in film tearing effect.

[0007] In some embodiments, the folding assembly further includes a sliding post disposed on the side of the longitudinal sliding plate opposite to the transverse sliding plate. The sliding post extends in a direction perpendicular to the plane of the longitudinal sliding plate. The lifting member includes a pushing portion and a connecting portion connected together. The pushing portion extends in the horizontal direction and corresponds to the longitudinal sliding plate in the vertical direction. The connecting portion extends in the vertical direction and corresponds to the side of the longitudinal sliding plate opposite to the transverse sliding plate. The connecting portion has a sliding hole adapted to the sliding post. The sliding post is slidably disposed in the sliding hole so that the longitudinal sliding plate and the connecting portion are slidably connected.

[0008] In some embodiments, the angle between the extension direction of the sliding hole and the vertical direction is an acute angle, and the end of the sliding hole away from the pushing part is disposed towards the material carrier plate.

[0009] In some embodiments, the film-tearing device further includes a material transfer assembly, which includes a material transfer drive and a material transfer gripper. The material transfer drive is disposed near the support frame, and the material transfer gripper is connected to the material transfer drive. The material transfer gripper is used to grasp the workpiece, and the material transfer drive is used to drive the material transfer gripper to move so that the material transfer gripper presses the workpiece onto the carrier plate and makes the film part opposite to the clearance groove.

[0010] In some embodiments, the translation assembly includes a translation drive and a translation member connected to the translation drive. The translation drive is connected to the support frame, and the translation member is also connected to the sliding seat. The translation drive is used to drive the translation member to move closer to or away from the carrier plate in the horizontal direction.

[0011] In some embodiments, the clamping assembly includes a clamping drive and two clamping fingers connected to the clamping drive. The clamping drive is connected to the longitudinal sliding plate, and the two clamping fingers are disposed close to the material carrier plate. The clamping drive is used to drive the two clamping fingers to move closer or further apart from each other to clamp or release the membrane.

[0012] In some embodiments, the carrier plate is provided with positioning protrusions, which are used to abut against the workpiece to position the workpiece.

[0013] In some embodiments, the film-tearing device further includes an air-blowing assembly, which includes an air supply component and an air pipe. The air supply component is connected to the support frame, and the air pipe is connected to the air supply component and disposed near the material carrier plate. The air pipe has a plurality of air outlets facing the clamping assembly. The air supply component is used to supply air to the air pipe to blow air onto the clamping assembly through the plurality of air outlets, thereby blowing off the film after the clamping assembly releases the film.

[0014] In some embodiments, the film-tearing device further includes a collection component, which includes a waste bin disposed below the material carrier plate and is used to collect the film.

[0015] In some embodiments, the collection assembly further includes a suction pipe, one end of which is connected to the bottom of the waste bin, and the other end of which is connected to an external air extraction device. The suction pipe is used to extract the membrane from the waste bin. Attached Figure Description

[0024] The embodiments of this application will be further described below with reference to the accompanying drawings. To facilitate understanding and explanation of the embodiments of this application, a three-dimensional coordinate system is established in some of the drawings, with the X-axis direction being the horizontal direction, the Z-axis direction being the vertical direction, and the X-axis, Y-axis, and Z-axis directions being perpendicular to each other.

[0025] Please see Figure 1 , Figure 2 and Figure 3 This application provides a film-tearing device 100 for tearing film 300 off a workpiece 200. The workpiece 200 can be an accessory for electronic products, such as a ribbon cable or glass panel. The electronic products can be mobile phones, tablets, or electronic watches. The film 300 can be plastic film, release paper, etc. In this embodiment, the film 300 has a film head protruding from the workpiece 200 to facilitate film tearing. Multiple film 300s, such as two or three, can be attached to the workpiece 200, and the film 300s are not attached to the ends of the workpiece 200. The film-tearing device 100 includes a support frame 10, a translation component 20, a film-folding component 30, a lifting component 40, and a clamping component 50.

[0026] Specifically, the support frame 10 is provided with a carrier plate 11 for supporting and positioning the workpiece 200. The carrier plate 11 is provided with a relief groove 111 corresponding to the film 300, which is used to avoid obstructing the film 300. It can be understood that the carrier plate 11 provides a positioning function for the workpiece 200. A fixing mechanism (not shown) can be provided on the carrier plate 11 to fix the workpiece 200, or the workpiece 200 can be pressed onto the carrier plate 11 by the transfer gripper 62 described below to improve the stability of the workpiece 200 when tearing the film. The relief groove 111 corresponds to the film 300 to avoid obstructing the film 300. In this embodiment, when multiple film 300s are attached to the workpiece 200, multiple relief grooves 111 can be provided in a one-to-one correspondence, or a single relief groove 111 can be provided to avoid obstructing multiple film 300s.

[0027] The translation component 20 is connected to the support frame 10. The translation component 20 can be a cylinder assembly, a linear module, etc.

[0028] The film folding assembly 30 includes a sliding base 31, a transverse sliding plate 32, a longitudinal sliding plate 33, a first elastic element 34, and a second elastic element 35. The sliding base 31 is connected to the translation assembly 20. The transverse sliding plate 32 is slidably connected to the side of the sliding base 31 away from the translation assembly 20 in the horizontal direction. The longitudinal sliding plate 33 is slidably connected to the side of the transverse sliding plate 32 away from the sliding base 31 in the vertical direction. The two ends of the first elastic element 34 are respectively connected to the sliding base 31 and the transverse sliding plate 32. The first elastic element 34 is used to pull the transverse sliding plate 32 to move horizontally closer to the carrier plate 11 after being stretched. The two ends of the second elastic element 35 are respectively connected to the transverse sliding plate 32 and the longitudinal sliding plate 33. The second elastic element 35 is used to pull the longitudinal sliding plate 33 to move vertically closer to the carrier plate 11 after being stretched. The sliding seat 31 is fixedly connected to the translation component 20. When the translation component 20 drives the sliding seat 31 to move horizontally, the sliding seat 31 drives the transverse sliding plate 32 and the longitudinal sliding plate 33 to move synchronously horizontally. The first elastic element 34 and the second elastic element 35 can both be springs, etc. In this embodiment, the end of the first elastic element 34 connected to the sliding seat 31 is close to the support frame 10, and the end of the first elastic element 34 connected to the transverse sliding plate 32 is away from the support frame 10. The end of the second elastic element 35 connected to the transverse sliding plate 32 is close to the material carrier plate 11, and the end of the second elastic element 35 connected to the longitudinal sliding plate 33 is away from the material carrier plate 11.

[0029] The lifting assembly 40 includes a lifting drive 41 and a lifting member 42 connected to the lifting drive 41. The lifting drive 41 is connected to the sliding seat 31, and the lifting member 42 is also inclined and slidably connected to the longitudinal sliding plate 33 in the direction toward the material carrier plate 11. The lifting drive 41 can be a cylinder or the like. It is understood that the lifting drive 41 moves synchronously with the sliding seat 31 in the horizontal direction.

[0030] The clamping assembly 50 is connected to the side of the longitudinal sliding plate 33 away from the lifting member 42 and is located close to the material carrier plate 11. The clamping assembly 50 is used to clamp the film 300.

[0031] When multiple film elements 300 are provided on the workpiece 200, this embodiment can provide multiple translation components 20, film folding components 30, lifting components 40, and clamping components 50, such as two, three, or four, so that the multiple clamping components 50 can be arranged around the carrier plate 11 to clamp the multiple film elements 300. When multiple translation components 20 are provided, the translation components 20 drive their corresponding connected film folding components 30, lifting components 40, and clamping components 50 to move closer to or away from the carrier plate 11 in the horizontal direction. At this time, the horizontal direction can be the X-axis direction, the Y-axis direction, or a direction that forms an angle with the X-axis and Y-axis, as long as it is within the XY plane, and is not limited here. In this embodiment, the translation component 20 that moves in the X-axis direction is used as an example for explanation, and the other translation components 20 and their corresponding film folding components 30, lifting components 40, and clamping components 50 will not be described in detail.

[0032] The film-tearing device 100 provided in this application embodiment can support and position the workpiece 200 via the material carrier plate 11 on the support frame 10. The material carrier plate 11 has a relief groove 111 for avoiding the film 300. When the workpiece 200 is placed on the material carrier plate 11, the film 300 corresponds to the relief groove 111, which facilitates the separation of the film 300 from the workpiece 200. During film tearing, the translation component 20 drives the film-folding component 30, the lifting component 40, and the clamping component 50 to move horizontally toward the material carrier plate 11. The lifting drive component 41 of the lifting component 40 drives the lifting component 42 to move vertically, thereby pushing the longitudinal sliding plate 33 of the film-folding component 30 and the clamping component 50 connected to the longitudinal sliding plate 33 to move vertically toward the material carrier plate 11. Since the longitudinal sliding plate 33 and the lifting member 42 are inclined and slidably connected in the direction toward the material carrier plate 11, while the lifting drive member 41 drives the lifting member 42 to rise in the vertical direction, the longitudinal sliding plate 33 slides relative to the lifting member 42 and moves closer to the lifting member 42, and moves away from the material carrier plate 11 relative to the lifting member 42 in the horizontal direction. The longitudinal sliding plate 33 also drives the transverse sliding plate 32 to move away from the material carrier plate 11 relative to the lifting member 42 in the horizontal direction. At this time, the transverse sliding plate 32 stretches the first elastic member 34, and the longitudinal sliding plate 33 stretches the second elastic member 35. When the clamping assembly 50 moves to the position corresponding to the film 300 under the driving action of the translation assembly 20 and the lifting assembly 40, the clamping assembly 50 clamps the film 300. Then, the lifting drive 41 drives the lifting member 42 to retract. The first elastic member 34 pulls the transverse sliding plate 32 to move horizontally toward the material carrier plate 11, thereby driving the longitudinal sliding plate 33 and the clamping assembly 50 to move horizontally toward the material carrier plate 11. The second elastic member 35 pulls the longitudinal sliding plate 33 to move vertically away from the lifting member 42, thereby driving the clamping assembly 50 to continue moving toward the workpiece 200 to bend the film head of the film 300, so that the film head of the film 300 is tilted relative to the workpiece 200. Next, the translation component 20 drives the film-folding component 30, the lifting component 40, and the clamping component 50 to move horizontally away from the carrier plate 11. The lifting drive component 41, through the lifting component 42, drives the longitudinal sliding plate 33 and the clamping component 50 to move vertically away from the carrier plate 11. After bending the film head of the film 300, the clamping component 50 tears the film 300 off the workpiece 200 in an inclined tearing manner. The aforementioned film-tearing device 100 can automatically adjust the tearing direction during film tearing, first tilting the film head of the film 300 relative to the workpiece 200, and then tearing off the film 300. This can effectively avoid damage to the workpiece 200 or the film 300 caused by film tearing, resulting in high work efficiency and high consistency in film tearing effect.

[0033] In some embodiments, see Figure 2 , Figure 3 and Figure 4The folding assembly 30 also includes a sliding post 36, which is disposed on the side of the longitudinal sliding plate 33 away from the transverse sliding plate 32. The sliding post 36 extends in a direction perpendicular to the plane of the longitudinal sliding plate 33. The lifting member 42 includes a pushing part 421 and a connecting part 422 connected together. The pushing part 421 extends in a horizontal direction and corresponds to the longitudinal sliding plate 33 in a vertical direction. The connecting part 422 extends in a vertical direction and corresponds to the side of the longitudinal sliding plate 33 away from the transverse sliding plate 32. The connecting part 422 has a sliding hole 4221 adapted to the sliding post 36. The sliding post 36 is slidably disposed in the sliding hole 4221 so that the longitudinal sliding plate 33 and the connecting part 422 are slidably connected.

[0034] The sliding hole 4221 is a strip-shaped hole. To improve the smoothness of the movement of the sliding column 36 within the sliding hole 4221, a roller, bearing, or similar device can be installed at one end of the sliding column 36 inserted into the sliding hole 4221. The sliding column 36 of the longitudinal sliding plate 33 and the sliding hole 4221 of the lifting member 42 form a precision sliding pair, allowing the longitudinal sliding plate 33 to move along a preset oblique trajectory during the lifting process. Thus, when the lifting drive member 41 drives the lifting member 42 to rise, the sliding column 36 slides along the sliding hole 4221 until the sliding column 36 abuts against the lower end of the sliding hole 4221 or the longitudinal sliding plate 33 abuts against the pushing part 421, guiding the longitudinal sliding plate 33 horizontally away from the load plate 11 relative to the lifting member 42, thereby stretching the second elastic member 35. The longitudinal sliding plate 33 drives the transverse sliding plate 32 horizontally away from the load plate 11 relative to the lifting member 42, thereby stretching the first elastic member 34. When the lifting drive 41 stops driving the lifting member 42 to rise, the first elastic member 34 can pull the transverse sliding plate 32 to move horizontally closer to the carrier plate 11. This, in turn, drives the longitudinal sliding plate 33 to move horizontally closer to the carrier plate 11, while the second elastic member 35 pulls the longitudinal sliding plate 33 to move vertically closer to the carrier plate 11. Thus, when the lifting drive 41 drives the lifting member 42 to descend, the combined action of the transverse sliding plate 32, the longitudinal sliding plate 33, the first elastic member 34, and the second elastic member 35 bends the film member 300, facilitating subsequent film removal.

[0035] In some embodiments, see Figure 2 , Figure 3 and Figure 4The sliding hole 4221 has an acute angle between its extension direction and the vertical direction, and the end of the sliding hole 4221 away from the pushing part 421 is positioned towards the carrier plate 11. Thus, during the ascent of the lifting member 42, the sliding column 36 slides obliquely downwards in the sliding hole 4221, thereby guiding the longitudinal sliding plate 33 to move horizontally relative to the lifting member 42 away from the carrier plate 11, simultaneously driving the transverse sliding plate 32 to move horizontally relative to the lifting member 42 away from the carrier plate 11. Alternatively, when the lifting member 42 stops rising or falling, the first elastic element 34 and the second elastic element 35 pull the sliding column 36 obliquely upwards in the sliding hole 4221, thereby guiding the longitudinal sliding plate 33 to move horizontally and vertically towards the carrier plate 11, thus allowing the clamping assembly 50 to bend the film 300.

[0036] In some embodiments, see Figure 1 and Figure 2 The film-tearing device 100 also includes a material transfer assembly 60, which includes a material transfer drive 61 and a material transfer gripper 62. The material transfer drive 61 is located near the support frame 10, and the material transfer gripper 62 is connected to the material transfer drive 61. The material transfer gripper 62 is used to grasp the workpiece 200, and the material transfer drive 61 is used to drive the material transfer gripper 62 to move, so that the material transfer gripper 62 presses the workpiece 200 onto the carrier plate 11 and makes the film 300 opposite to the clearance groove 111. The material transfer drive 61 can be a robotic arm, etc., and the material transfer gripper 62 can be a suction cup gripper. By setting the material transfer assembly 60, loading and unloading can be performed automatically, improving the degree of automation. After the material transfer drive 61 drives the material transfer gripper 62 to place the workpiece 200 onto the carrier plate 11, the material transfer gripper 62 can press the workpiece 200, improving the stability of the workpiece 200 during film tearing, thereby improving the film tearing stability.

[0037] In some embodiments, see Figure 2 , Figure 3 and Figure 4 The translation assembly 20 includes a translation drive 21 and a translation member 22 connected to the translation drive 21. The translation drive 21 is connected to the support frame 10, and the translation member 22 is also connected to the sliding seat 31. The translation drive 21 is used to drive the translation member 22 to move horizontally closer to or away from the material carrier plate 11. The translation drive 21 can be a cylinder or the like, and the translation member 22 can be an L-shaped plate structure. The translation drive 21 can drive the translation member 22 to move horizontally, thereby driving the film folding assembly 30, the lifting assembly 40, and the clamping assembly 50 to move horizontally.

[0038] In some embodiments, see Figure 2 , Figure 3 and Figure 4The clamping assembly 50 includes a clamping drive 51 and two clamping fingers 52 connected to the clamping drive 51. The clamping drive 51 is connected to the longitudinal sliding plate 33, and the two clamping fingers 52 are positioned close to the material carrier plate 11. The clamping drive 51 drives the two clamping fingers 52 to move closer or further apart to clamp or release the film 300. The clamping drive 51 can be a double-headed cylinder, and the clamping fingers 52 can be a quadrangular prism structure. By driving the two clamping fingers 52 to move, the film 300 can be clamped or released. To improve the stability of film tearing, an anti-slip surface can be provided on the side of the clamping fingers 52 that contacts the film 300.

[0039] In some embodiments, see Figure 2 , Figure 3 and Figure 4 The carrier plate 11 is provided with a positioning protrusion 112, which is used to abut against the workpiece 200 to position the workpiece 200. By providing the positioning protrusion 112, the position of the workpiece 200 placed on the carrier plate 11 can be accurately positioned, improving the accuracy of the position of the workpiece 200 and the film 300, and thus improving the accuracy of the clamping assembly 50 when clamping the film 300.

[0040] In some embodiments, see Figure 1 and Figure 2 The film-tearing device 100 also includes an air-blowing assembly 70, which includes an air supply component 71 and an air pipe 72. The air supply component 71 is connected to the support frame 10, and the air pipe 72 is connected to the air supply component 71 and is located near the material carrier plate 11. The air pipe 72 has multiple air outlets 721 facing the clamping assembly 50. The air supply component 71 supplies air to the air pipe 72 to blow air onto the clamping assembly 50 through the multiple air outlets 721, thereby blowing off the film 300 after the clamping assembly 50 releases the film 300. The air supply component 71 can be an air pump, etc., and the air outlets 721 in the air pipe 72 can be six, eight, ten, etc. By setting up the air-blowing assembly 70, air can be blown onto the film 300 after the clamping assembly 50 tears off and releases the film 300, thereby blowing off the film 300 between the clamping fingers 52 and preventing the film 300 from remaining between the clamping fingers 52 and affecting the next film-tearing.

[0041] In some embodiments, see Figure 1 and Figure 2 The film-tearing device 100 also includes a collection component 80, which includes a waste bin 81 located below the material carrier plate 11. The waste bin 81 is used to collect the film components 300. By setting up the waste bin 81, waste film components 300 can be collected, improving the cleanliness of the production environment and facilitating the handling of waste film components 300 by operators.

[0042] In some embodiments, see Figure 1 and Figure 2The collection component 80 also includes a suction pipe 82. One end of the suction pipe 82 is connected to the bottom of the waste bin 81, and the other end is connected to an external air extraction device (not shown). The suction pipe 82 is used to extract the membrane components 300 from the waste bin 81. By setting up the suction pipe 82, the waste membrane components 300 in the waste bin 81 can be extracted in a timely manner, reducing the accumulation of membrane components 300 in the waste bin 81. It can also automatically collect the waste membrane components 300, improve the degree of automation, and effectively reduce the labor intensity of operators.

[0043] The working process of the film-peeling device 100 provided in this embodiment is roughly as follows: First, the transfer drive 61 of the transfer assembly 60 drives the transfer gripper 62 to place the workpiece 200 on the carrier plate 11 of the support frame 10, and positions the workpiece 200 by the positioning protrusion 112. When placing the workpiece 200, the side of the workpiece 200 that is in contact with the film 300 is set towards the clearance groove 111, and the transfer gripper 62 presses the workpiece 200.

[0044] Then, the translation drive 21 of the translation assembly 20 drives the translation member 22 to move horizontally toward the support frame 10, thereby causing the folding assembly 30, the lifting assembly 40, and the clamping assembly 50 to move horizontally toward the carrier plate 11. The lifting drive 41 of the lifting assembly 40 drives the lifting member 42 to move vertically. The sliding hole 4221 guides the sliding column 36 to slide in the sliding hole 4221 until the sliding column 36 abuts against the lower end of the sliding hole 4221 or the longitudinal sliding plate 33 abuts against the pushing part 421, so as to guide the longitudinal sliding plate 33 to move horizontally away from the carrier plate 11 relative to the lifting member 42, thereby stretching the second elastic member 35. The longitudinal sliding plate 33 drives the transverse sliding plate 32 to move horizontally away from the carrier plate 11 relative to the lifting member 42, thereby stretching the first elastic member 34. At this time, the lifting drive 41 continues to drive the longitudinal sliding plate 33 and the clamping assembly 50 to move upward through the lifting component 42 until the clamping assembly 50 and the membrane 300 are aligned in the vertical direction.

[0045] Next, the clamping drive 51 drives the two clamping fingers 52 to clamp the film 300, the lifting drive 41 drives the lifting member 42 to move downward, the first elastic member 34 pulls the transverse sliding plate 32 to move horizontally toward the material carrier plate 11, thereby driving the longitudinal sliding plate 33 and the clamping assembly 50 to move horizontally toward the material carrier plate 11, and the second elastic member 35 pulls the longitudinal sliding plate 33 to move vertically away from the lifting member 42 until the sliding column 36 abuts against the upper wall of the sliding hole 4221, thereby driving the clamping assembly 50 to continue moving toward the workpiece 200 to bend the film head of the film 300 so that the film head of the film 300 is tilted relative to the workpiece 200.

[0046] Finally, the lifting drive 41 drives the lifting component 42 to move downward, thereby driving the sliding column 36 and the longitudinal sliding plate 33 to move away from the material carrier plate 11 in the vertical direction through the upper wall of the sliding hole 4221. The translation component 20 drives the film folding component 30, the lifting component 40 and the clamping component 50 to move away from the material carrier plate 11 in the horizontal direction. Then, after the clamping component 50 bends the film head of the film 300, the film 300 is torn off the workpiece 200 by tilting the film.
