Description

Technical Field

[0001] The present application relates to the technical field of automated production equipment, and in particular to a film tearing mechanism, a pick-and-place assembly, and a film tearing device. Background Art

[0002] In the production process of consumer electronic products, there is a process that requires a large number of workpieces (such as glass cover plates, gemstone cover plates, etc.) to be evenly adhered to the same large film (that is, a large-size film that is compatible with the coated plate), and then lamination, transportation and other operations are performed.

[0003] In the subsequent production process, the aforementioned large number of workpieces need to be separated from the large film. The existing separation method is basically to absorb the workpiece through the suction cup assembly, and then directly use the lifting assembly to lift the suction cup assembly to drive the workpiece to move upward and tear it off from the large film. In the actual operation process, this separation method will cause the large film to be pulled to a higher position, the separation efficiency is low and it is easy to cause the position of other workpieces on the large film to change, which is not conducive to the subsequent separation of the remaining workpieces. At the same time, in such a tearing and separation process, the upper and lower surfaces of the workpiece need to bear the pulling force from the suction cup assembly and the large film respectively, wherein the pulling force applied by the suction cup assembly is mainly concentrated in the middle of the workpiece, and the direction is vertically upward, while the pulling force applied by the large film is located at the peeling openings on both sides of the workpiece, and the direction is vertically downward or inclined downward, which is easy to cause fracture and damage in the middle or both sides of the workpiece, which is not conducive to ensuring the product yield.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0051] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0052] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0053] In order to solve the technical problems in the prior art that the workpiece tearing method has low separation efficiency and is prone to breakage and damage of the workpiece, the present application provides a film tearing mechanism, a pick-up and placement assembly and a film tearing device, which can form a connection with the workpiece 730 through the workpiece pick-up and placement module 210 during film tearing, and drive the large film 700 to move smoothly in a direction away from the workpiece 730 through the film moving assembly 300, so that the large film 700 can be peeled off from one side of the workpiece 730, which is beneficial to improving the stress state of the workpiece 730 during the film tearing process, while ensuring the film tearing effect without affecting the pick-up and placement positions of other workpieces 730, and is beneficial to improving the separation efficiency of the workpiece 730 carried on the large film 700.

[0054] See also Figures 1 to 17 In a first aspect, the present application provides a film tearing mechanism, including a film placement platform 100 and a pick-and-place assembly 200 and a film transfer assembly 300 movably arranged relative to the film placement platform 100. Figure 1 Specifically, the pick-and-place assembly 200 is movably disposed at one end of the film-placing platform 100. During the film-tearing process of the workpiece 730, the film-moving assembly 300 drives the large film 700 to move as a whole, so that the workpieces 730 on the large film 700 are moved row by row close to the pick-and-place assembly 200, so that the pick-and-place assembly 200 can remove the workpieces 730 carried on the large film 700 row by row.

[0055] The pick-and-place assembly 200 includes a workpiece pick-and-place module 210 and a film pressing module 220. Both the workpiece pick-and-place module 210 and the film pressing module 220 have a plurality of one-to-one corresponding working ends that can be raised and lowered. Figure 2 The workpiece picking and placing module 210 includes a plurality of first working ends 211, which can be used to synchronously pick and place a plurality of workpieces 730 in the same row, which is beneficial to improving the film tearing and separation efficiency of the workpieces 730; the film pressing module 220 includes a plurality of second working ends 221, which can be used to press down the large film body 710 at the front end of the plurality of workpieces 730 arranged in the same row, so as to prevent the large film 700 at the front end of the workpiece 730 from bulging (or arching), thereby affecting the separation operation of the workpiece 730 and the large film body 710.

[0056] The film transfer assembly 300 includes a first film clamping module 310 and a second film clamping module 320 distributed at both ends of the film placement platform 100, which are used to clamp the front and rear ends of the large film 700. During the film peeling process of the workpiece 730, the first film clamping module 310 and the second film clamping module 320 clamp the large film 700 and move it smoothly relative to the film placement platform 100, and can cooperate with the pick-and-place assembly 200 to realize the large film 700 being peeled off from one side of the workpiece 730, such as Fig.12As shown. During the movement of the large film 700, the first film clamping module 310 and the second film clamping module 320 always clamp the large film 700, so that the arrangement position of the workpieces 730 on the film placement platform 100 remains stable, which can prevent the placement position of other workpieces 730 from being offset due to the placement of the front row of workpieces 730, which is conducive to improving the film tearing and separation efficiency of the workpieces 730.

[0057] It should be noted that, in the initial state, the first film clamping module 310 and the second film clamping module 320 are distributed at the front and rear ends of the film placement platform 100, and the first film clamping module 310 is close to the pick-and-place assembly 200. The first film clamping module 310 clamps the front end of the large film body 710, and the second film clamping module 320 clamps the rear end of the large film body 710, and the large film body 710 carries a plurality of workpieces 730. During the film tearing process of the workpiece 730, the first film clamping module 310 moves in the direction away from the workpiece picking and placing module 210, and also away from the front end of the film placing platform 100, and the direction of moving away can be vertically downward or inclined downward; and the second film clamping module 320 moves from the rear end of the film placing platform 100 to the front end of the film placing platform 100 as the large film 700 moves. At this time, the positions of the first film clamping module 310 and the second film clamping module 320 relative to the film placing platform 100 will change, but the large film 700 is always kept taut under the clamping of the first film clamping module 310 and the second film clamping module 320.

[0058] It should be noted that the first working end 211 can be connected to the workpiece 730 by adsorption or clamping. In order to avoid interference between the workpiece 730 on the first working end 211 and the workpiece 730 on the large film 700 behind it during the movement of the large film 700, during the film tearing process of the workpiece 730, the pick-and-place assembly 200 moves synchronously with the large film 700, and there is always a film tearing opening between the workpiece 730 and the large film body 710, such as Fig.12 Preferably, in order to improve the stress state of the workpiece 730 during the film tearing process, the pick-and-place assembly 200 moves along the workpiece 730 during the film tearing process. Fig.12 The horizontal movement from right to left can make the large film body 710 be peeled off from the left side of the workpiece 730. The side peeling method improves the stress on the workpiece 730, avoids the breakage of the workpiece 730, improves the film tearing and separation efficiency of the workpiece 730, and is beneficial to improving the yield of the workpiece 730.

[0059] In some embodiments of this application, please refer to Figure 2 and Figure 3In order to achieve the lifting and lowering adjustment of the first working end 211 and the second working end 221, the workpiece pick-up and place module 210 further includes a first driving member 212 connected to the first working end 211, and the film pressing module 220 further includes a second driving member 222 connected to the second working end 221. Specifically, the first driving member 212 and the second driving member 222 can be driving members such as a lifting cylinder or a lifting oil cylinder.

[0060] In the existing large film 700, if the large film body 710 is not sticky, the large film 700 includes, in addition to the large film body 710 and the plurality of workpieces 730, a small film 720 disposed between the large film body 710 and the workpieces 730. The upper and lower surfaces of the small film 720 are sticky, and the main body size is the same as the workpiece 730. The workpiece 730 can be adhered to the large film body 710 through the small film 720. In order to facilitate the separation of the small film 720 and the workpiece 730, a small film ear protruding from the front end of the workpiece 730 is provided at the front end of the small film 720, such as Figure 5 When the workpiece 730 is torn off, the small film 720 and the large film body 710 need to be separated from the workpiece 730. Fig.12 As shown, at this time, the film tearing opening needs to be formed between the workpiece 730 and the small film 720.

[0061] In order to solve the above problem, in some embodiments of the present application, the second working end 221 matches the small membrane ear at the front end of the small membrane 720, and the small membrane ear can be pressed down by the second working end 221, so that the small membrane 720 forms a tearing opening with the workpiece 730 from the small membrane ear, such as Fig.12 After the workpiece 730 is torn off, the small film 720 is still adhered to the large film body 710 and moves synchronously with the large film body 710 in a direction away from the workpiece 730 .

[0062] Preferably, the second working end 221 is a pressing plate, and the bottom end of the pressing plate presses down on the small film ear when the workpiece 730 is tearing the film, so that a tearing film opening is formed between the small film 720 and the workpiece 730. In order to enable the pressing plate to accurately press down on the small film ear, the film pressing module 220 also includes a third driving member 223 connected to the second driving member 222 and the second working end 221 respectively. The third driving member 223 is a rotating driving member that can drive the pressing plate to rotate, so that the pressing plate is aligned with the small film ear, and the contact area between the pressing plate and the small film ear is increased, so as to facilitate the effective downward pressure on the small film ear.

[0063] In some embodiments of this application, please refer to Figure 6 , Figure 8 and Fig.12A film guiding structure 110 that can be movably adjusted is disposed at one end of the film placing platform 100 close to the pick-and-place assembly 200. The film guiding direction of the film guiding structure 110 is toward the first film clamping module 310, which can reduce the friction force generated when the first film clamping module 310 drives the large film 700 to move relative to the front end of the film placing platform 100.

[0064] The film guide structure 110 is movably disposed in the film mounting frame 130 at the front end of the film mounting platform 100, and can be extended or retracted into the film mounting frame 130. Figure 6 In the extended state, Figure 8 When the film guide structure 110 is retracted into the film mounting frame 130, it can avoid affecting the first film clamping module 310 clamping the front end of the large film body 710. After the first film clamping module 310 completes the film clamping and moves away from the film mounting platform 100 for a certain distance, the film guide structure 110 extends out from the film mounting frame 130 to form a support guide for the back of the large film body 710, so that the large film body 710 is bent at the film guide structure 110, avoiding the large film body 710 from directly contacting the end surface of the film mounting frame 130. Fig.12 As shown, the friction during the movement of the large film 700 can be reduced.

[0065] In some preferred embodiments of the present application, the film guide structure 110 can be slidably arranged on the film mounting frame 130 in the horizontal direction, so that the film guide structure 110 can extend or retract the front end of the film mounting platform 100. The film guide structure 110 includes a rotatably arranged film guide roller, which can further reduce the friction between the film guide structure 110 and the large film body 710, which is conducive to achieving smooth movement of the large film 700.

[0066] In some embodiments of the present application, the top plate of the film rack 130 can be heated. When the large film 700 carrying the workpiece 730 moves onto the film rack 130, the heated top plate can weaken the adhesion between the workpiece 730 and the small film 720, thereby facilitating the separation of the workpiece 730 from the small film 720.

[0067] In some embodiments of this application, please refer to Figure 7 , Figure 8 and Fig. 9, the first film clamping module 310 includes a clamping member 311, a lifting plate 312, a sliding seat 313 and a lifting drive member 314. Among them, a plurality of clamping members 311 are sequentially arranged on the lifting plate 312, and the film clamping opening of the clamping member 311 is arranged toward the film placing platform 100, so that the front end of the large film 700 can be extended into the film clamping opening. The number of clamping members 311 and the distance between adjacent clamping members 311 are set according to the width size of the large film 700, so as to form a stable clamping for the front end of the large film 700. The lifting plate 312 is slidably arranged on the sliding seat 313 in the vertical direction, and is connected to the lifting drive member 314, so that the lifting plate 312 can move in the vertical direction relative to the sliding seat 313. After the clamping member 311 completes the clamping of the front end of the large film 700, the lifting drive member 314 and the clamping member 311 can drive the large film body 710 and the small film 720 away from the workpiece 730, so as to realize the film tearing of the workpiece 730.

[0068] It should be noted that, in order to make the large film body 710 and the small film 720 away from the workpiece 730 fixed by the first working end 211, the clamping member 311 on the first film clamping module 310 can continue to move vertically downward, or it can first move downward and then move horizontally, so that the large film body 710 moves downward at an angle, so that the film tearing opening always exists. When the large film 700 is long (such as more than 1 meter), it is preferred to lower the lifting plate 312 and the plurality of clamping members 311 as a whole to the bottom of the film guide structure 110 through the lifting drive member 314, and then drive the lifting plate 312 and the clamping members 311 as a whole to slide horizontally toward the rear end of the film placement platform 100 (i.e. Fig.12 In this case, the workpiece placement module 210 and the first film clamping module 310 move in opposite directions, which is more conducive to tearing off the large film body 710 and the small film 720 away from the workpiece 730, such as Fig.12 and Fig.16 In order to realize the horizontal sliding of the first film clamping module 310, the film transfer assembly 300 further includes a first sliding module 330 connected to the first film clamping module 310, as shown. Figure 7 , Figure 8 and Fig. 9 shown.

[0069] In some embodiments of this application, please refer to Figure 6 and Fig.10 The film placing platform 100 has a movable conveying surface 121, and a large film 700 carrying a plurality of workpieces 730 can be placed on the conveying surface 121, and the large film 700 is stably supported by the conveying surface 121. The moving speed of the second film clamping module 320 is adapted to the moving speed of the conveying surface 121, so as to avoid wrinkles or pulling of the large film 700 due to the different moving speeds of the conveying surface 121 and the second film clamping module 320.

[0070] It should be noted that the conveying surface 121 can be a plane where the tops of multiple conveying rollers are located, or it can be a top plane of a conveyor belt, both of which can achieve stable support for the large film 700. Preferably, since the large film 700 is a flexible structure, in order to avoid the large film 700 from collapsing when the spacing between adjacent conveying rollers is large, it is preferred to use a conveying module 120 with a conveyor belt to convey the large film 700. Specifically, the conveying module 120 also includes a driving component 122, which is connected to the conveyor belt with the conveying surface 121, so that the conveying surface 121 can move synchronously with the large film 700 and the second film clamping module 320.

[0071] In some embodiments of this application, please refer to Figure 7 and Fig.10 The second film clamping module 320 includes a plurality of film clamping ends 321 distributed on both sides of the film placement platform 100, which can clamp both sides of the rear end of the large film 700 to avoid interference with the conveying surface 121 and other components in the middle of the film placement platform 100. The plurality of film clamping ends 321 can move synchronously, which can ensure the stability of the movement of the large film 700 and avoid wrinkles or pulling of the large film 700 due to the asynchronous movement of the film clamping ends 321 on both sides.

[0072] In some embodiments of this application, please refer to Fig.10 The film transfer assembly 300 also includes a second sliding module 340 connected to the second film clamping module 320, and the second sliding module 340 includes a seventh driving member 341, a linking member 342, a transmission assembly 343 and a first slide rail 344. Among them, the seventh driving member 341 is connected to the transmission assemblies 343 on both sides of the film placement platform 100 through the linking member 342, and the synchronous driving of the transmission assemblies 343 on both sides can be realized. The transmission assemblies 343 on both sides of the film placement platform 100 are respectively connected to the film clamping ends 321 on both sides of the film placement platform 100, and are used to drive the film clamping ends 321 to slide back and forth along the first slide rail 344. The film clamping ends 321 on both sides of the film placement platform 100 are synchronously driven to move by the seventh driving member 341, so as to reduce the number of driving members, which is conducive to reducing the equipment cost. Specifically, the transmission assembly 343 can adopt components such as a belt transmission assembly or a chain transmission assembly.

[0073] In some embodiments of this application, please refer to Fig.11The second film clamping module 320 also includes a fifth driving member 322, a sixth driving member 323 and a connecting seat 324 which are arranged corresponding to the film clamping end 321. The fifth driving member 322 is a driving member such as a lifting cylinder or a lifting oil cylinder, and the sixth driving member 323 is a driving member such as a horizontal cylinder or a horizontal oil cylinder, which can move the film clamping end 321 in the vertical direction and the horizontal direction, so as to adjust the film clamping position of the film clamping end 321. The connecting seat 324 is used to connect with the transmission assembly 343 and the first slide rail 344, and can drive the fifth driving member 322, the sixth driving member 323 and the film clamping end 321 to move along the length direction of the film placing platform 100 as a whole.

[0074] In some embodiments of this application, please refer to Figure 2 , Figure 7 and Figure 8 The pick-and-place assembly 200 includes a curved film structure 231 that can be raised and lowered, and the end of the curved film structure 231 can be fitted into the film opening of the first film clamping module 310. When the front end of the large film 700 extends out of the end of the film mounting frame 130 (at this time, the film guide structure 110 is in a retracted state), the front end of the large film 700 can be pressed into the film opening of the first film clamping module 310 through the curved film structure 231, so that the first film clamping module 310 can clamp the front end of the large film 700. Automatic clamping can be achieved, and there is no need to manually put the front end of the large film 700 into the film opening of the first film clamping module 310, which can improve the degree of automation of the film tearing mechanism, which is conducive to improving the film tearing efficiency of the workpiece 730.

[0075] In some embodiments of this application, please refer to Figure 2 The bent film module 230 in the pick-and-place assembly 200 includes a bent film structure 231 and a fourth driving member 232. The fourth driving member 232 is a driving member such as a lifting cylinder or a lifting oil cylinder, which can be used to drive the bent film structure 231 to move in the vertical direction. After the film is clamped, the bent film structure 231 is lifted to avoid interference with the subsequent film tearing process.

[0076] In some embodiments of this application, please refer to Figure 2 and Figure 3 The pick-and-place component 200 also includes a visual positioning module 240, which is signal-connected to the workpiece pick-and-place module 210 and the film pressing module 220, so as to facilitate the positioning of the workpiece 730 and the small film ears through the visual positioning module 240, and facilitate the working ends of the workpiece pick-and-place module 210 and the film pressing module 220 to achieve precise movements.

[0077] In some embodiments of the present application, the visual positioning module 240 includes multiple CCD cameras, which are arranged corresponding to the first working end 211 and the second working end 221, and can be used to position multiple workpieces 730 or small membrane ears in the same row, and the driving parts in the workpiece picking and placing module 210 and the film pressing module 220 can independently adjust the action according to the positioning information, so as to facilitate the precise positioning of the position of each small membrane ear or workpiece 730, so that the first working end 211 can accurately adsorb or clamp the workpiece 730, and the second working end 221 can accurately press down the small membrane ear at the front end of the workpiece 730, so that a film tearing opening is generated between the small membrane 720 and the workpiece 730.

[0078] In the above embodiments, in order to prevent the workpiece 730 at the bottom of the first working end 211 from interfering with the moving large film 700, in some embodiments of the present application, see Figure 4 , connect the pick-and-place assembly 200 to the moving assembly 800 , and move the pick-and-place assembly 200 relative to the film placement platform 100 through the moving assembly 800 .

[0079] It should be noted that the moving component 800 can be any component that can cause the pick-and-place component 200 to move horizontally. Figure 2 and Figure 4 , the moving assembly 800 includes a third sliding module 810, a mounting beam 820, a fourth sliding module 830, a second slide rail 840 and a support frame 850. The mounting frame 250 of the pick-and-place assembly 200 is arranged on the third sliding module 810, so that the pick-and-place assembly 200 can be moved along the width direction of the large film 700, so that multiple working ends and the workpiece 730 are aligned in the width direction of the large film 700. The third sliding module 810 is arranged on the mounting beam 820, and the mounting beam 820 is respectively connected to the fourth sliding module 830 and the second slide rail 840, which can drive the pick-and-place assembly 200 to move horizontally in the length direction of the large film 700, so that the pick-and-place assembly 200 is close to or away from the film placement platform 100. The fourth sliding module 830 and the second sliding rail 840 are arranged on the support frame 850 to raise the overall height of the pick-and-place assembly 200 so that the pick-and-place assembly 200 is located above the film placement platform 100, which is convenient for tearing off the large film 700 on the film placement platform 100.

[0080] In some embodiments of this application, please refer to Fig. 9 , Fig.13 and Fig.14The film tearing mechanism also includes a waste film recovery component 400, which is disposed below the film placement platform 100. When all the workpieces 730 on the large film 700 are removed, the first film clamping module 310 moves the large film body 710 and the small film 720 (i.e., waste film) as a whole to below the film placement platform 100. After the first film clamping module 310 and the second film clamping module 320 are released, the waste film falls onto the waste film recovery component 400 below the film placement platform 100, thereby realizing waste film recovery. It is understandable that the moving paths of the first film clamping module 310 and the second film clamping module 320 are adapted to the recovery path of the waste film, so that the waste film can be recovered along the predetermined path.

[0081] It should be noted that the waste film recovery component 400 can be a recovery box arranged under the film placement platform 100, but multiple layers of waste films fall randomly into the recovery box, which will cause a lot of space waste inside the recovery box, and the amount of waste films that can be recovered is limited.

[0082] In order to avoid the above problems, in some embodiments of the present application, please refer to Fig.13 and Fig.14 The waste film recovery component 400 includes a recovery platform 410 movably disposed below the film placement platform 100 and clamping modules 420 distributed around the recovery platform 410. When recovering the waste film, the recovery platform 410 approaches the film placement platform 100 under the action of the lifting component, so that the waste film clamped by the first film clamping module 310 and the second film clamping module 320 is placed on the recovery platform 410, and the clamping modules 420 disposed around the recovery platform 410 clamp the edge of the waste film, and then the first film clamping module 310 and the second film clamping module 320 are released, and the recovery platform 410 moves downward with the waste film to avoid interference with the reset of the first film clamping module 310. This waste film recovery method can enable a large amount of waste film to be regularly stacked and fixed, which is conducive to improving the recovery capacity of the waste film recovery component 400.

[0083] The second aspect of the embodiment of the present application provides a pick-and-place component 200, which is suitable for a film tearing mechanism. The film tearing mechanism has a conveying surface 121 for conveying a large film 700. The pick-and-place component 200 includes a workpiece pick-and-place module 210 and a film pressing module 220. The workpiece pick-and-place module 210 and the film pressing module 220 both have multiple working ends that correspond one to one and can be raised and lowered. The multiple working ends cooperate with the large film 700 to remove the workpiece 730 on the large film 700.

[0084] In some embodiments of this application, please refer to Figure 2 and Figure 3The pick-and-place assembly 200 also includes a bending film module 230, a visual positioning module 240 and a mounting frame 250. The workpiece pick-and-place module 210, the film pressing module 220 and the bending film module 230 are all connected to the visual positioning module 240 by signal. The workpiece pick-and-place module 210, the film pressing module 220, the bending film module 230 and the visual positioning module 240 are arranged on the mounting frame 250, so that each module is connected into a whole, which is convenient for driving the pick-and-place assembly 200 to move as a whole through the moving assembly 800.

[0085] The third aspect of the embodiments of the present application provides a film tearing device, including a loading and unloading device 500 and the film tearing mechanism described in the above embodiments. The loading and unloading device 500 acts on the loading end and / or unloading end of the film tearing mechanism to realize the loading and unloading of large films 700 and / or workpieces 730.

[0086] In some embodiments of this application, please refer to Fig.15 and Fig.17 The loading and unloading equipment 500 includes a large film loading mechanism 510, which is used to move the large film 700 carrying multiple workpieces 730 from the large film separation mechanism 900 to the film placement platform 100 of the film tearing mechanism to realize the loading of the large film 700.

[0087] Specifically, the large film loading mechanism 510 includes a film lifting assembly 511, a Z-axis sliding module 512, an X-axis sliding module 513, a Y-axis sliding module 514 and a gantry 515. The film lifting assembly 511 is used to clamp the two ends of the large film 700. The Z-axis sliding module 512, the X-axis sliding module 513, and the Y-axis sliding module 514 arranged on the gantry 515 enable the film lifting assembly 511 to clamp the large film 700 and move it in the Z, X and Y directions, thereby realizing the loading of the large film 700.

[0088] In some embodiments of this application, please refer to Fig.15 and Fig.16 The loading and unloading equipment 500 includes a workpiece unloading mechanism 520, and the support frame 850 of the moving component 800 is arranged above the workpiece unloading mechanism 520. The pick-and-place component 200 can place the workpiece 730 adsorbed or grasped by the first working end 211 on the workpiece unloading mechanism 520, and transport the workpiece 730 to the next process through the workpiece unloading mechanism 520.

[0089] In some embodiments of the present application, the film tearing device further includes a workbench 600, one or more film tearing mechanisms are disposed on the workbench 600, and the waste film recovery component 400 is disposed inside the workbench 600. In order to allow the waste film to fall into the waste film recovery component 400 inside the workbench 600, a through-feeding port 610 is provided on the workbench body 620, such as Fig.13 , Fig.15 and Fig.16 shown.

[0090] In some preferred embodiments of the present application, multiple film tearing mechanisms are arranged on the workbench 600. By having multiple film tearing mechanisms working simultaneously, the production efficiency can be greatly improved. The large film loading mechanism 510 can act on the loading ends of multiple film tearing mechanisms to transfer a large film 700 carrying a workpiece 730 to each film tearing mechanism.

[0091] See also Figures 1 to 17 In some embodiments of the present application, the film tearing method of the film tearing device is as follows:

[0092] Step 1: The large membrane loading mechanism 510 moves the large membrane 700 separated on the large membrane separation mechanism 900 to the membrane placement platform 100 , so that the front end of the large membrane 700 extends out of the front end of the membrane placement platform 100 .

[0093] Step 2: The second film clamping module 320 clamps the rear end of the large film 700, and the pick-and-place assembly 200 moves so that the curved film structure 231 is located above the front end of the large film 700. The curved film structure 231 descends to press the front end of the large film 700 into the film clamping opening of the first film clamping module 310, so that the first film clamping module 310 clamps the front end of the large film 700. The curved film structure 231 rises and resets, and the first film clamping module 310 descends, so that the large film 700 is tightened, and the first row of small film ears on the large film 700 extend out of the front end of the film holder 130.

[0094] Step 3: The visual positioning module 240 takes a photo to position the workpiece 730 and the small membrane ear, and the pick-and-place component 200 adjusts its position according to the positioning information so that the first working end 211 is located above the workpiece 730 and the second working end 221 is located above the small membrane ear.

[0095] Step 4: the film pressing module 220 is activated, and the second working end 221 is pressed downward to form a film tearing opening between the small film 720 and the workpiece 730 ; the first working end 211 adsorbs the workpiece 730 .

[0096] Step 5: The first film clamping module 310, the second film clamping module 320 and the conveying surface 121 move synchronously at an adapted moving speed; the pick-and-place assembly 200 moves horizontally as a whole in a direction away from the film placing platform 100 and the second film clamping module 320, and the large film body 710 and the small film 720 are torn off from one side of the workpiece 730 under the joint action of the pick-and-place assembly 200 and the film transfer assembly 300, as shown in FIG. Fig.12 shown.

[0097] Step 6: The pick-and-place assembly 200 moves to the top of the workpiece unloading mechanism 520, the first working end 211 descends, and the workpiece 730 is placed on the workpiece unloading mechanism 520, so that the workpiece 730 flows to the next process. The pick-and-place assembly 200 moves toward the film placement platform 100 again to pick up the next row of workpieces 730.

[0098] Step 7: After all workpieces 730 on the large film 700 are placed, the large film body 710 and the small film 720 (i.e., waste film) are located below the film placement platform 100. The recovery platform 410 rises to receive the waste film, and the clamping module 420 on the side of the recovery platform 410 clamps the side of the waste film, then the first clamping module 310 and the second clamping module 320 are released, and the recovery platform 410 descends to complete the waste film recovery.
