Description

Technical Field

[0001] This invention relates to the field of film peeling technology, and in particular to an automatic film peeling device and a film peeling and recycling method. Background Technology

[0002] During the production of FPC (Flexible Printed Circuit) boards, the surface of the FPC board is covered with a PSA (Platelet-Side Attachment) film, which needs to be separated from the FPC board later. Traditional film-removing equipment first brings the film-removing mechanism close to the product to be peeled, then uses a suction nozzle to pick up a corner of the PSA film from the FPC board, causing the PSA film to move in the opposite direction to complete the peeling process. However, this method is susceptible to external factors during the suction and peeling process, which can easily cause the PSA film to fall off the suction nozzle, making it difficult to guarantee the peeling effect and work efficiency. In addition, existing film-tearing equipment typically uses positive pressure air blowing to make the waste film fall into the waste box during the waste film recycling process. However, the air pressure of the positive pressure air blowing recycling method is difficult to control, which has the following problems: 1) When the positive pressure air blowing is too high, the waste film is easily blown out of the waste box and falls into the product or equipment, causing product quality problems and safety hazards; 2) When the positive pressure air blowing is too low, the waste film cannot detach from the suction nozzle, and may fall onto the product during the film-tearing mechanism, which also causes quality problems.

[0003] Therefore, there is an urgent need for an automatic film-tearing device and a film-tearing and recycling method to solve the above-mentioned technical problems. Summary of the Invention

[0004] Based on the above, the purpose of this invention is to provide an automatic film-tearing device and a film-tearing and recycling method, which can ensure reliable film gripping and prevent the film from falling off during the transfer process; at the same time, it can achieve accurate and complete film recycling when recycling waste film, preventing the film from falling into the product or equipment and causing product quality problems and safety hazards.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Automatic film-peeling equipment, including:

[0007] A conveying mechanism transports a carrier to the film-peeling station, the carrier carrying products to be peeled.

[0008] A lifting mechanism is located below the conveying mechanism, and the lifting mechanism is positioned opposite the carrier located at the film-tearing station;

[0009] The transfer mechanism includes a first direction motion module, a second direction motion module, and a third direction motion module that are perpendicular to each other;

[0010] A film-tearing mechanism is disposed at the output end of the third-direction motion module. The film-tearing mechanism includes an adsorption component and a clamping component. The adsorption component includes a first driving member and an adsorption member. The first driving member drives the adsorption member to move along the third direction to absorb the film. The clamping component includes a second driving member and a clamping member. The second driving member drives the clamping member to move along a second direction to move closer to or further away from the adsorption member. The clamping member cooperates with the adsorption member to clamp the film.

[0011] Waste film recycling mechanism includes a recycling bag and a negative pressure generating device. The negative pressure generating device is located at the inlet end of the recycling bag and draws in the film through negative pressure.

[0012] In some possible implementations, the negative pressure generating device includes a first valve body and a second valve body. The first valve body has an adsorption chamber, and the second valve body has a diffusion chamber. The adsorption chamber and the diffusion chamber communicate with each other to form an adsorption channel. The second valve body also has an air inlet chamber. The side wall of the second valve body has a positive pressure air inlet that communicates with the air inlet chamber and is connected to external compressed air. An acceleration injection port is provided between the first valve body and the second valve body, and the acceleration injection port communicates with the air inlet chamber and the diffusion chamber. The second valve body is connected to the inlet end of the recycling bag, and the outlet of the diffusion chamber communicates with the recycling bag.

[0013] In some possible implementations, the conveying mechanism includes a first conveying component and a second conveying component extending along a second direction, the first conveying component and the second conveying component being spaced apart along a first direction, and the carrier being placed on the first conveying component and the second conveying component; the spacing between the first conveying component and the second conveying component along the first direction is adjustable.

[0014] In some possible implementations, the conveying mechanism further includes a first position sensor corresponding to the loading station, a second position sensor corresponding to the film-tearing station, and a third position sensor corresponding to the unloading station.

[0015] In some possible implementations, the automatic film-tearing device further includes a blocking mechanism disposed below the conveying mechanism and downstream of the film-tearing station. The blocking mechanism includes a blocking cylinder and a baffle, wherein the blocking cylinder drives the baffle to move in a third direction to block the carrier.

[0016] In some possible implementations, the lifting mechanism includes a mounting frame, a lifting cylinder, a lifting plate, and a guide assembly. The lifting cylinder is fixed to the mounting frame and drives the lifting plate to move in a third direction. The guide assembly includes a guide sleeve fixed to the mounting frame and a guide post slidably disposed within the guide sleeve. The top of the guide post is connected to the lifting plate.

[0017] In some possible implementations, a positioning post is provided at the top of the lifting plate, and a positioning hole is provided at the bottom of the carrier, with the positioning post engaging with the positioning hole; and / or,

[0018] The top of the lifting plate is provided with a positioning hole, and the bottom of the carrier is provided with a positioning post, which is inserted into the positioning hole.

[0019] In some possible implementations, the film-tearing mechanism further includes a film-tearing connecting seat and a first sliding assembly. The film-tearing connecting seat is throttlely connected to the output end of the third-direction motion module. The first driving member and the second driving member are both fixed on the film-tearing connecting seat. The first sliding assembly includes a first slide rail and a first slider. The first slide rail extends along a second direction and is fixed on the film-tearing connecting seat. The first slider is slidably connected to the first slide rail. The clamping member is fixed on the first slider.

[0020] In some possible implementations, the film-tearing connector is provided with at least two sets of one-to-one corresponding adsorption components and clamping components. The film-tearing mechanism also includes a linkage component, which is connected to the output end of the second driving component. The linkage component is respectively connected to each of the first sliders to drive each clamping component to move synchronously along the second direction.

[0021] A film removal and recycling method, used in any of the above-described automatic film-removing devices, the method comprising:

[0022] The carrier holding the product to be peeled off is transported to the peeling station;

[0023] The carrier in the film-peeling station is lifted and positioned.

[0024] Move the film-tearing mechanism above the product to be peeled, control the adsorption component to pick up the film, and control the clamping component to cooperate with the adsorption component to clamp the film;

[0025] The film-peeling mechanism moves along a set path to completely peel the film off the product.

[0026] The film-tearing mechanism is moved above the waste film recycling mechanism, and the clamping assembly and the adsorption assembly are controlled to release the film. At the same time, the waste film recycling mechanism is controlled to suck the film into the recycling bag through negative pressure.

[0027] The beneficial effects of this invention are:

[0028] This invention first uses a conveying mechanism to transport a carrier containing the product to be peeled to the peeling station. Then, a lifting mechanism lifts the carrier to detach it from the conveying mechanism. Next, a transfer mechanism moves the peeling mechanism above the product. An adsorption component picks up the corners of the film, thus peeling the film off the product. After picking up the film, a first driving component drives the adsorption component to rise with the film, and a second driving component drives the clamping component to approach the adsorption component. The clamping component and the adsorption component work together to clamp the film. Then, the transfer mechanism moves the peeling mechanism along a set path to completely peel the film off the product. After that, the transfer mechanism moves the peeling mechanism above the waste film recycling mechanism, aligning the film with the recycling port of the waste film recycling mechanism. At this time, the clamping component and the adsorption component move to release the clamping and adsorption of the film. At the same time, a negative pressure generating device generates a large flow of negative pressure to accurately suck the film into the recycling bag. This invention uses the combination of clamping and adsorption components to clamp the film, effectively ensuring the reliability of film clamping and preventing the film from falling off during the transfer process. Moreover, during the recycling of waste film, a negative pressure generating device generates negative pressure to suck the film into the recycling bag, ensuring accurate and complete recycling of the film and preventing the film from falling into the product or equipment and causing product quality problems and safety hazards.

[0057] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0058] like Figures 1 to 16As shown, this embodiment of the invention provides an automatic film-removing device for products that require the removal and recycling of waste film after PSA film application. The automatic film-removing device includes a conveying mechanism 1, a lifting mechanism 2, a transfer mechanism 3, a film-removing mechanism 4, and a waste film recycling mechanism 5. The conveying mechanism 1 is used to transport a carrier 100 carrying products to be peeled. Specifically, the conveying mechanism 1 can drive the carrier 100 between a loading station, a film-removing station, and a unloading station to achieve the transfer of the carrier 100 between different stations. When the carrier 100 reaches the film-removing station, the film to be peeled from the product on the carrier 100 can be peeled. The lifting mechanism 2 is located below the conveying surface of the conveying mechanism 1, and the lifting mechanism 2 is positioned opposite the carrier 100 at the film-removing station. The lifting mechanism 2 is used to lift the carrier 100 upwards to separate the carrier 100 from the conveying mechanism 1. The transfer mechanism 3 includes a first-direction motion module 31, a second-direction motion module 32, and a third-direction motion module 33, which are perpendicular to each other. The film-tearing mechanism 4 is located at the output end of the third-direction motion module 33, thus enabling the film-tearing mechanism 4 to achieve three-axis motion along the first, second, and third directions. It should be noted that the first, second, and third directions in this embodiment are perpendicular to each other. Specifically, the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction. The film-tearing mechanism 4 includes an adsorption component 41 and a clamping component 42. The adsorption component 41 includes a first driving member 411 and an adsorption member 412. The adsorption member 412 is used to pick up the corner parts of the film, and the first driving member 411 is used to drive the adsorption member 412 to rise or fall along the Z direction. The clamping component 42 includes a second driving member 421 and a clamping member 422. The second driving member 421 is used to drive the clamping member 422 to move along the Y direction to approach or move away from the adsorption member 412, and the clamping member 422 can cooperate with the adsorption member 412 to clamp the film. Optionally, the first driving component 411 and the second driving component 421 are both cylinders, resulting in a simple structure and convenient control. The waste film recycling mechanism 5 includes a recycling bag 51 and a negative pressure generating device 52. The negative pressure generating device 52 is located at the inlet end of the recycling bag 51. When the film tearing mechanism 4 moves above the waste film recycling mechanism 5, the negative pressure generating device 52 generates a large flow of negative pressure to suck the waste film into the recycling bag 51. Furthermore, the film tearing device in this embodiment also includes a base 7, on which the conveying mechanism 1, lifting mechanism 2, transfer mechanism 3, and waste film recycling mechanism 5 are all mounted. By setting the base 7, this embodiment facilitates the unified layout and centralized installation of various modules such as the conveying mechanism 1, lifting mechanism 2, transfer mechanism 3, and waste film recycling mechanism 5, improving the integration and compactness of the equipment.

[0059] The working process of the automatic film-peeling device provided in this embodiment is as follows: First, the carrier 100 carrying the product to be peeled is transported to the film-peeling station by the conveying mechanism 1; then, the carrier 100 is lifted by the lifting mechanism 2; then, the film-peeling mechanism 4 is moved above the product to be peeled by the transfer mechanism 3, and the adsorption member 412 is driven to move downward by the first driving member 411. The adsorption member 412 picks up the corner of the film. After the film is picked up, the first driving member 411 drives the adsorption member 412 to carry the film upward, thereby peeling the film off the product, and at the same time providing clearance for the movement of the clamping member 422; then, the second driving member 421 drives the clamping member 422 to move closer to the adsorption member 412. 12, so that the clamping surface of the clamping member 422 is directly below the adsorption surface of the adsorption member 412. Then, the first driving member 411 moves again to drive the adsorption member 412 to move down, so that the adsorption member 412 and the clamping member 422 clamp the film together. Then, the transfer mechanism 3 drives the film tearing mechanism 4 to move along the set path to completely peel the film from the product. Next, the transfer mechanism 3 drives the film tearing mechanism 4 to move above the waste film recycling mechanism 5, so that the film is aligned with the recycling port of the waste film recycling mechanism 5. At this time, the clamping member 422 and the adsorption member 412 move to release the clamping and adsorption of the film. At the same time, the negative pressure generating device 52 generates a large flow negative pressure to accurately suck the film into the recycling bag 51.

[0060] In this embodiment, the clamping member 422 and the adsorption member 412 work together to clamp the film, which effectively ensures the reliability of film clamping and prevents the film from falling off during the transfer process. Moreover, during the recycling of waste film, the negative pressure generating device 52 generates a large flow of negative pressure to suck the film into the recycling bag 51, which ensures the accurate and complete recycling of the film and prevents the film from falling into the product or equipment and causing product quality problems and safety hazards.

[0061] Optionally, the negative pressure generating device 52 includes a first valve body 521 and a second valve body 522. The first valve body 521 is located at the end away from the recycling bag 51. One end of the second valve body 522 is fixedly connected to the first valve body 521, and the other end of the second valve body 522 is connected to the inlet end of the recycling bag 51. The first valve body 521 has an adsorption port 5211, which is the recycling port of the waste membrane recycling mechanism 5. An adsorption chamber 5212 communicating with the adsorption port 5211 is provided inside the first valve body 521. A diffusion chamber 5221 is provided inside the second valve body 522. The outlet of the diffusion chamber 5221 is connected to the recycling bag 51. The adsorption chamber 5212 and the diffusion chamber 5221 are connected to form an adsorption channel, through which the waste membrane can enter the recycling bag 51. Optionally, the adsorption chamber 5212 is funnel-shaped, gradually expanding from the inside to the outside, which is more conducive to the entry of the membrane. The second valve body 522 also includes an air inlet chamber 5222. A positive pressure air inlet 5223, communicating with the air inlet chamber 5222, is located on the side wall of the second valve body 5222. The positive pressure air inlet 5223 is connected to an external compressed air supply device to allow compressed air to be introduced into it. Optionally, the air inlet chamber 5222 is arranged annularly within the second valve body 522, and surrounds the outer periphery of the diffuser chamber 5221. This increases the capacity of the air inlet chamber 5222, facilitating the intake of more compressed air. Specifically, the second valve body 522 includes an outer ring portion 5224 and an inner ring portion 5225. An intake chamber 5222 is disposed between the outer ring portion 5224 and the inner ring portion 5225. The top end of the intake chamber 5222 (i.e., the end near the first valve body 521) is open. The bottom end of the first valve body 521 (i.e., the end near the second valve body 522) is provided with an abutment surface 5213. The bottom end of the first valve body 521 abuts against the top end of the second valve body 522 and is fixed by fasteners. The abutment surface 5213 seals the open portion of the intake chamber 5222. In this embodiment, an acceleration injection port 523 is also provided between the first valve body 521 and the second valve body 522. The acceleration injection port 523 connects the intake chamber 5222 and the diffuser chamber 5221 to allow compressed air from the intake chamber 5222 to enter the diffuser chamber 5221.

[0062] Optionally, the accelerating injection port 523 is a narrow gap between the first valve body 521 and the second valve body 522. Specifically, the top end of the inner ring portion 5225 is an arc-shaped surface, and the aforementioned narrow gap exists between the arc-shaped surface and the contact surface 5213, allowing compressed gas in the intake chamber 5222 to enter the diffuser chamber 5221 through this narrow gap. Further, the diameter of this narrow gap gradually increases from one end near the intake chamber 5222 to the other end near the diffuser chamber 5221 to facilitate airflow; and the arc-shaped surface is inclined towards the interior of the diffuser chamber 5221 to facilitate the introduction of airflow into the diffuser chamber 5221. Optionally, a groove 5214 is also provided at the bottom end of the first valve body 521, and a sealing ring 524 is installed in the groove 5214 to achieve a seal between the contact surfaces of the first valve body 521 and the second valve body 522, preventing gas leakage from the intake chamber 5222. Optionally, the waste membrane recycling mechanism further includes a fixing frame 53, which is fixed to the base 7, and the negative pressure generating device 52 is fixed to the fixing frame 53. Optionally, the recycling bag 51 in this embodiment is a flexible bag, and the recycling bag 51 is made of breathable material or has air vents to allow airflow to be discharged outward. This embodiment utilizes the high-speed airflow generated when positive pressure compressed air passes through the accelerating jet port 523 to form a low-pressure area near the outlet of the accelerating jet port 523, thereby creating a vacuum effect to draw the waste membrane into the adsorption channel; the vacuum output of the negative pressure generating device 52 can reach 3 to 4 times the positive pressure supply airflow, and its large-flow vacuum can completely and effectively recycle the waste membrane into the recycling bag 51, improving the waste membrane recycling effect and efficiency.

[0063] The working principle of the waste film recycling unit 5 is explained below:

[0064] When compressed air is injected into the intake chamber 5222 through the positive pressure intake port 5223, the compressed air in the intake chamber 5222 narrows the airflow channel as it passes through the narrow acceleration injection port 523, and the airflow speed increases sharply, thus generating an acceleration effect. The high-speed jet ejected from the acceleration injection port 523 to the diffuser chamber 5221 has a suction effect, which can drive the surrounding still fluid to flow forward with it. Therefore, the air near the outlet of the acceleration injection port 523 will be continuously sucked away. As the air near the outlet of the acceleration injection port 523 is continuously sucked away, the amount of air in the adsorption chamber 5212 decreases, and the outside air cannot be replenished in time, causing the pressure in the adsorption chamber 5212 to gradually drop below atmospheric pressure, forming a certain degree of vacuum. As the compressed air is continuously injected and the jet suction effect continues, the air in the adsorption chamber 5212 is continuously discharged, and the vacuum degree is maintained. At the same time, the compressed air mixed with the surrounding air will be further decelerated and pressurized through the diffuser chamber 5221 and discharged from the outlet of the diffuser chamber 5221. When waste film needs to be recycled, the transfer mechanism 3 drives the film tearing mechanism 4 to move above the waste film recycling mechanism 5 and align the waste film with the adsorption port 5211. Then, the clamping member 422 and the adsorption member 412 cooperate to release the waste film, and the adsorption member 412 stops adsorbing the waste film. At the same time, the negative pressure generating device 52 of the waste film recycling mechanism 5 starts the positive pressure air source to generate a large flow of negative pressure and accurately suck the waste film into the recycling bag 51.

[0065] It should be noted that in some embodiments, during the process of recycling waste membrane, the adsorption element 412 can be controlled to blow air downwards to make the membrane fall. This not only ensures the complete separation of the membrane from the adsorption element 412, but also accelerates the entry of the membrane into the waste membrane recycling mechanism 5, further improving the recycling efficiency.

[0066] Optionally, the film-tearing mechanism 4 in this embodiment further includes a film-tearing connecting seat 43 and a first sliding assembly. The film-tearing connecting seat 43 is the supporting mechanism of the entire film-tearing mechanism 4, and the first driving member 411, the second driving member 421, and the first sliding assembly are all fixed on the film-tearing connecting seat 43. The film-tearing connecting seat 43 is drively connected to the output end of the third-direction motion module 33, thus realizing the movement of the film-tearing connecting seat 43 with the transfer mechanism 3. The first sliding assembly includes a first slide rail 441 and a first slider 442. The first slide rail 441 extends along the Y direction and is fixed on the first driving member 411, the first slider 442 is slidably connected to the first slide rail 441, and the clamping member 422 is fixed on the first slider 442. The above arrangement allows the clamping member 422 to slide smoothly along the Y direction, improving the movement accuracy of the clamping member 422.

[0067] Specifically, the adsorption member 412 includes a connecting arm 4121 and a suction nozzle 4122. The connecting arm 4121 is fixed to the output end of the first driving member 411, and the suction nozzle 4122 is fixed to the connecting arm 4121 with the suction port of the suction nozzle 4122 facing downward. The bottom surface of the connecting arm 4121 is flush with the adsorption surface of the suction nozzle 4122, and the bottom surface of the connecting arm 4121 is the upper clamping surface. The clamping member 422 is L-shaped and includes a longitudinal extension arm 4221 and a transverse extension arm 4222. The longitudinal extension arm 4221 is fixedly connected to the first slider 442, and the transverse extension arm 4222 is located at the lower end of the longitudinal extension arm 4221 and extends toward the adsorption member 412. The top surface of the transverse extension arm 4222 is the lower clamping surface. In this way, the film can be reliably clamped by the tight fit between the upper clamping surface and the lower clamping surface. Optionally, anti-slip textures 48 are provided on both the upper and lower clamping surfaces to increase friction when gripping the film and prevent the film from falling off during tearing and transfer. Specifically, the anti-slip textures 48 can be striped, serrated, or mesh-like, etc.

[0068] Optionally, the film-tearing connector 43 is provided with at least two sets of one-to-one corresponding adsorption components 41 and clamping components 42 for simultaneously tearing the film off at least two products. Exemplarily, this embodiment provides three adsorption components 41 and three clamping components 42; correspondingly, the waste film recycling device 5 includes three negative pressure generating devices 52 and three corresponding recycling bags 51; and three products to be peeled are loaded on the same carrier 100, thus enabling simultaneous film peeling and recycling of three products at once, greatly improving processing efficiency. Further, to simplify the structure of the film-tearing mechanism 4, this embodiment can simultaneously drive multiple clamping components 422 through a second driving member 421 to reduce the number of second driving members 421. Specifically, the film-tearing connecting seat 43 is provided with a second driving member 421, multiple clamping members 422, and multiple sets of first slide rails 441 and first sliders 442; the film-tearing mechanism 4 also includes a linkage member 45, which is tractively connected to the output end of the second driving member 421, and the linkage member 45 is provided with multiple positioning grooves 451; each first slider 442 is fixed with a linkage rod 46, and each linkage rod 46 is correspondingly engaged in each positioning groove 451. In this configuration, when the second driving member 421 drives the linkage member 45, it can simultaneously drive multiple clamping members 422 to move synchronously along the Y direction. Optionally, the film-tearing connecting seat 43 is also provided with a limit rod 47 to limit the movement position of the linkage member 45.

The second direction motion module 32 includes a second fixed base 321 fixed to the first connecting base 313, a second drive component 322 fixed to the second fixed base 321, and a second connecting base 323 connected to the output end of the second drive component 322.

The third direction motion module 33 includes a third fixed base 331 fixed to the second connecting base 323, a third drive component 332 fixed to the third fixed base 331, and a third connecting base 333 connected to the output end of the third drive component 332. The third drive component 332 can drive the third connecting base 333 to move along the Z direction. The film-tearing connector 43 is fixed to the third connector 333, thus enabling the transfer mechanism 3 to drive the film-tearing mechanism 4 to achieve three-axis motion along the X, Y, and Z directions. Furthermore, the transfer mechanism 3 is also equipped with drag chains along the X, Y, and Z directions respectively, for the protection of electrical circuits. Optionally, the first drive assembly 312, the second drive assembly 322, and the third drive assembly 332 are all lead screw and nut mechanisms to ensure motion accuracy and operational stability.

[0070] Optionally, the conveying mechanism 1 includes a first conveying component 11 and a second conveying component 12 that are parallel to each other and extend along the Y direction respectively. The first conveying component 11 and the second conveying component 12 are spaced apart in the X direction, and the carrier 100 is placed on the first conveying component 11 and the second conveying component 12. This arrangement saves space and facilitates the placement of the lifting mechanism 2 and the blocking mechanism 6 between the first conveying component 11 and the second conveying component 12.

[0071] In some embodiments, the first conveying assembly 11 includes a first support frame 111, a first conveyor belt 112, and a first motor 113. The first support frame 111 is fixed to the base 7, and a first transmission wheel assembly is mounted on the first support frame 111. The first conveyor belt 112 is wound around the first transmission wheel assembly, and the first motor 113 is fixed to the first support frame 111. The first motor 113 is drively connected to the first transmission wheel assembly, thereby driving the first conveyor belt 112 to rotate. The second conveying assembly 12 includes a second support frame 121, a second conveyor belt 122, and a second motor 123. The second support frame 121 is fixed to the base 7, and a second transmission wheel assembly is mounted on the second support frame 121. The second conveyor belt 122 is wound around the second transmission wheel assembly, and the second motor 123 is fixed to the second support frame 121. The second motor 123 is drively connected to the second transmission wheel assembly, thereby driving the second conveyor belt 122 to rotate.

[0072] Furthermore, the distance between the first conveying assembly 11 and the second conveying assembly 12 along the X direction is adjustable, thus adapting to various carriers 100 of different sizes and improving the versatility of the conveying mechanism 1. Specifically, the conveying mechanism 1 also includes a second sliding assembly and a fourth driving assembly 14. The second sliding assembly includes a second slide rail 131 extending along the X direction and a second slider 132 slidably connected to the second slide rail 131, with a second support frame 121 fixed to the second slider 132. The output end of the fourth driving assembly 14 is connected to the second support frame 121 to drive the second support frame 121 to move along the X direction. This achieves adjustment of the distance between the first conveying assembly 11 and the second conveying assembly 12 in the X direction, resulting in a simple structure and reliable operation. Optionally, the fourth driving assembly 14 is a lead screw and nut mechanism to ensure motion accuracy and smooth operation.

[0073] Optionally, the conveying mechanism 1 further includes a first position sensor corresponding to the loading station, a second position sensor corresponding to the film-tearing station, and a third position sensor corresponding to the unloading station. By setting these sensors, the position of the carrier 100 on the conveying mechanism 1 can be detected, facilitating precise control of the actions of each mechanism. For example, when the carrier 100 moves to the film-tearing station, the second position sensor sends a signal to the controller, which then controls the lifting mechanism 2 to lift the carrier 100. It should be noted that the sensors can be contact sensors or photoelectric sensors, etc., and this embodiment does not impose any limitations on this.

[0074] Optionally, the lifting mechanism 2 in this embodiment includes a mounting frame 21, a lifting cylinder 22, a lifting plate 23, and a guide assembly. The mounting frame 21 is fixed to the base 7, and the lifting cylinder 22 is fixed to the mounting frame 21. The lifting cylinder 22 can drive the lifting plate 23 to move along the Z direction, thereby lifting the carrier 100. The guide assembly includes a guide sleeve 241 fixed to the mounting frame 21 and a guide post 242 slidably disposed within the guide sleeve 241. The guide post 242 extends along the Z direction, and its top is connected to the lifting plate 23, thus achieving the supporting and guiding function of the lifting plate 23. Furthermore, a positioning post 231 is provided at the top of the lifting plate 23, and a positioning hole 101 is provided at the bottom of the carrier 100. The positioning post 231 is inserted into the positioning hole 101 to ensure the positioning reliability between the lifting plate 23 and the carrier 100 and to ensure the film tearing accuracy. Of course, in other embodiments, a positioning hole can be provided on the top of the lifting plate 23 and a positioning post can be provided on the bottom of the carrier 100, which can also achieve the positioning of the carrier 100.

[0075] Furthermore, the automatic film-tearing device in this embodiment also includes a blocking mechanism 6. The blocking mechanism 6 is disposed below the conveying surface of the conveying mechanism 1 and downstream of the film-tearing station. When the carrier 100 is conveyed to the film-tearing station, the controller can control the blocking mechanism 6 to move, thereby blocking and limiting the carrier 100. Specifically, the blocking mechanism 6 includes a blocking cylinder 61, a baffle 62, and a bracket 63. The bracket 63 is fixed on the base 7, the blocking cylinder 61 is fixed on the bracket 63, and the baffle 62 is disposed at the output end of the blocking cylinder 61. The blocking cylinder 61 can drive the baffle 62 to rise and fall in the Z direction. When the carrier 100 is conveyed to the film-tearing station, the blocking cylinder 61 drives the baffle 62 to rise, blocking the carrier 100 from continuing to be conveyed downstream, thus ensuring the accuracy of the carrier 100's position.

[0076] This invention also provides a film tearing and recycling method for an automatic film tearing device, which specifically includes the following steps:

[0077] S1. The carrier 100 carrying the product to be peeled is transported to the peeling station by the conveying mechanism 1.

[0078] In this step, when the carrier 100 moves to the film-tearing station, the second position sensor is triggered and sends a signal to the controller so that the controller can control the actions of the lifting mechanism 2 and the blocking mechanism 6.

[0079] S2. The baffle 62 is driven to rise by the blocking cylinder 61 to block the carrier 100; the lifting plate 23 is driven to rise by the lifting mechanism 2 to lift the carrier 100 in the film-tearing position.

[0080] In this step, when the lifting plate 23 lifts the carrier 100, the positioning pin 231 on the lifting plate 23 can cooperate with the positioning hole 101 at the bottom of the carrier 100 to position the carrier 100 and prevent the film tearing failure due to the position deviation of the carrier 100.

[0081] S3. The transfer mechanism 3 drives the film-tearing mechanism 4 to move above the product to be peeled, controls the adsorption component 41 to pick up the film, and controls the clamping component 42 to cooperate with the adsorption component 41 to clamp the film.

[0082] It should be noted that since the film overlaps with the product, it cannot be directly clamped. Therefore, the film needs to be sucked up by the adsorption member 412, and then the adsorption member 412 is raised to lift the film, thus providing conditions for the clamping member 422 to clamp it. Specifically, the operation process of the film tearing mechanism 4 is as follows: First, the first driving member 411 drives the adsorption member 412 to move down, and the adsorption member 412 sucks up the corner of the film. After the film is sucked up, the first driving member 411 drives the adsorption member 412 to carry the film up, thereby peeling the film off the product; then the second driving member 421 drives the clamping member 422 to approach the adsorption member 412, so that the clamping surface of the clamping member 422 is directly below the adsorption surface of the adsorption member 412. Then, the first driving member 411 moves again to drive the adsorption member 412 to move down, so that the adsorption member 412 and the clamping member 422 together clamp the film.

[0083] S4. The transfer mechanism 3 drives the film-peeling mechanism 4 to move along a set path to completely peel the film off from the product.

[0084] S5. The transfer mechanism 3 drives the film tearing mechanism 4 to move above the waste film recycling mechanism 5, so that the film is aligned with the recycling port of the waste film recycling mechanism 5. The clamping component 42 and the adsorption component 41 are controlled to release the clamping and adsorption of the film. At the same time, the negative pressure generating device 52 is controlled to start the air source to generate a large flow negative pressure to accurately suck the film into the recycling bag 51.

[0085] In this step, when recycling waste membrane, the adsorption element 412 can also be controlled to open the blowing mode simultaneously, thereby blowing the membrane off to further improve the waste membrane recycling efficiency.

[0086] The film tearing and recycling method provided in this embodiment ensures the reliability of film clamping and prevents the film from falling off during the transfer process; at the same time, it can achieve accurate and complete recycling of the film when recycling waste film, avoiding the film falling into the product or equipment and causing product quality problems and safety hazards.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
