Description

Technical Field

[0001] The embodiments of the present application relate to the field of industrial electronic equipment, and in particular to a film removal device. Background Art

[0002] When a product is produced and packaged, a film is usually applied to the surface of the product to protect its appearance or provide insulation protection. When a product is defective or reaches its expiration date, the protective film on the surface of the product needs to be peeled off to achieve product recycling.

[0003] Existing product film removal methods mainly include manual film removal, laser film removal and film removal after crushing.

[0004] However, the manual film removal method has low film removal efficiency and poses certain safety risks; the laser film removal method will cause the protective film and the product to stick together when the melting points of the protective film and the product are close, making it impossible to separate the protective film and the product, and the products that can be removed are of a single shape, and it is impossible to remove the films from products of various shapes and heights at the same time; the post-crushing film removal method cannot guarantee the integrity of the product, and the separated products are easily mixed with impurities from the protective film, resulting in a low recycling rate. Summary of the invention

[0005] The embodiment of the present application provides a film removal device that can ensure the integrity of the product and can simultaneously remove the film from coated products of different shapes and heights without being limited by the melting points of the product and the protective film.

[0006] A film removal device, the device comprising a product receiving and clamping mechanism for receiving a product to be film removed and a film cutting mechanism for cutting a protective film of the product to be film removed, the film cutting mechanism comprising a cutting blade, a first horizontal guide rail assembly for driving the cutting blade to move horizontally, and a vertical guide rail assembly for driving the cutting blade to move vertically;

[0007] The cutting blade is used to cut the protective film of the product to be removed fixed on the product receiving and clamping mechanism, and moves up and down along the vertical guide rail assembly at different heights of the product to be removed to cut off the protective film at different heights on the product to be removed.

[0008] To summarize, through the technical solution of the present application, when removing the film from the coated product, a film cutting mechanism for cutting the protective film of the product to be removed is arranged in the film removal device, and the film cutting mechanism includes a cutting blade, a first horizontal guide rail assembly for driving the cutting blade to move horizontally, and a vertical guide rail assembly for driving the cutting blade to move vertically; when the cutting blade is used to cut the protective film of the product to be removed fixed on the product receiving and clamping mechanism, it moves up and down along the vertical guide rail assembly at different heights of the product to be removed to cut off the protective film at different heights on the product to be removed. In this way, during the film removal process, the horizontal guide rail assembly cooperates with the vertical guide rail assembly, so that the cutting blade can move horizontally along the product to be removed, and can move up and down along the vertical guide rail assembly as the height of the product to be removed changes, thereby meeting the film removal needs of products to be removed with different shapes, different heights, and large changes in curvature. In addition, the present application is not affected by the melting point of the product and its protective film. Even if the melting point of the product and its protective film is similar, the cutting blade can be driven by the horizontal guide rail assembly and the vertical guide rail assembly to effectively cut off the protective film on the product to be removed, so as to separate the product from the protective film.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or server that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0021] The film removal device provided in the embodiment of the present application can be applied to any field where film removal of film-coated products is required.

[0022] Before introducing the technical solution of the present application, the existing product film removal technology will be described below.

[0023] Most products on the market are coated on the surface of the product. On the one hand, it is to protect the appearance of the product and prevent the product from being scratched. For example, a protective film is covered on the antenna pole of a router to prevent the antenna pole of the router from being scratched by external forces. On the other hand, it is to insulate the product. For example, a protective film is applied to a lithium battery to insulate the lithium battery.

[0024] In order to avoid waste of resources, when there is a problem with the product's function or the product exceeds its service life, the product must be recycled. During the product recycling process, the product and the corresponding protective film must be peeled off first.

[0025] At present, the main methods for stripping the outer film of products in the industry are:

[0026] Method 1: Manual cutting and peeling: The operator uses a knife or other tool to cut the protective film on the coated product, and then rubs the protective film off the product by hand.

[0027] However, the manual cutting and peeling method is highly dependent on the operator's proficiency and is greatly restricted by personnel. When operators use knives to remove the film, they are prone to cut their hands, which poses a certain degree of safety risk. In addition, in the case of stickiness and static electricity between the protective film and the product, the protective film will stick to the product, and the operator needs to spend more time to tear the protective film off the product, resulting in low production efficiency.

[0028] Method 2, peeling after laser cutting: The laser generator emits a laser beam, which acts on the product protective film. The high-temperature laser beam can melt the protective film, and then the protective film is peeled off through a mechanical structure. This laser cutting and peeling method is often used in the peeling equipment of protective films such as lithium batteries.

[0029] However, the cost of using laser to melt the protective film is high; if the product height changes greatly or the curvature of the curved product is large, the laser generator cannot automatically focus on the product surface, resulting in the protective film in the unfocused area cannot be melted; for coated products such as plastics with a melting point close to the protective film, high-temperature laser acting on the product will melt the product and the protective film at the same time, causing the product and the protective film to stick together and cannot be peeled off. After the product protective film is manually peeled off, the material of the product will also be mixed with the material of the protective film. Secondary use can easily lead to undesirable phenomena such as discolored spots on the product during the production process; for example, the router antenna pole and the protective film on the antenna pole have similar melting points. When the high-temperature laser generated by the laser generator is used to melt the protective film on the antenna pole, the router antenna pole and the protective film on the antenna pole will melt at the same time, making it impossible to effectively separate the product and the protective film.

[0030] In addition, the principle of laser cutting is that high-energy, high-density lasers act on materials, causing the materials to reach high temperatures instantly and then melt. When the high-temperature laser beam acts on plastic materials such as protective films, pungent and toxic volatile gases will be generated, which are harmful to the environment and nearby workers. In addition, if there is stickiness and static electricity between the protective film and the product, the protective film will adhere to the product, and laser cutting cannot automatically separate the protective film. It is necessary to manually separate the protective film from the product and collect the product and the protective film into the corresponding collection box.

[0031] Method 3, separation after crushing: First, crush the products sealed with protective film into particles, and then use a high-powered fan to blow out high-speed airflow when the particles mixed with protective film are discharged from the discharge port. When the particles mixed with protective film pass through the airflow, due to the different densities of the protective film and the product, under the action of high-speed airflow, the low-density material will float farther with the high-speed airflow, and the high-density material will float a shorter distance, thereby separating the protective film from the product. This method is suitable for products with a small amount of protective film.

[0032] However, when the product is adhered to the protective film, the separation method after crushing cannot separate the adhered product from the protective film; and the separation method after crushing cannot guarantee the integrity of the product, and is not suitable for scenarios where the overall integrity of the product needs to be guaranteed. For example, when lithium batteries are removed from the film for recycling, the integrity of the lithium batteries cannot be destroyed. Therefore, the separation method after crushing cannot be used in lithium battery recycling. In addition, the product separated after crushing will inevitably be mixed with impurities from the protective film, making the purity of the recycled and reused product material poor. When the product is reused for the second time, it is easy to cause discolored spots on the product and abnormal material stress performance of the product, resulting in a high risk factor and a high scrap rate for the product produced again after product recycling.

[0033] Method 4, using a cutting device to remove the film, this method is usually used in the automatic film removal and recycling of lithium batteries. The film stripping device used in this solution is a hollow cylindrical structure, with cutting blades evenly installed at 90 degrees inside, and a scraper, brush, heating box and blower connected to the rear in sequence. The working principle is as follows: by pushing the lithium battery into the hollow cylinder, the blade will cut the battery protective film, and the ventilation duct in the cutting device will blow hot air to the battery protective film, causing the cut protective film to curl up on all sides, and then the protective film is removed by the scraper and brush, and finally falls into the collection box.

[0034] However, this method is only applicable to regular cylindrical products, such as 18650 lithium batteries, and cannot be applied to irregular products, such as router antenna rod covers; the equipment can only produce a single type of product at a time, and cannot produce products of different sizes and lengths at the same time; when the product protective film has a certain degree of viscosity or static electricity, the protective film will adhere to the product, and the use of a scraper brush to remove the film is not effective; this equipment needs to quickly heat the product in a short time, which means that the hot air heating power of the equipment is high, the power consumption is large, and the cost of use is high. In addition, under high temperature conditions, for products with low melting points such as plastics, such as router antenna rod covers, the product may melt at high temperature or the protective film may fuse with the product and cannot be separated.

[0035] As mentioned above, the existing film removal methods all have their own limitations. Under the premise of ensuring product integrity, on the one hand, when the melting points of the product and the protective film are close, the existing film removal methods will cause the protective film and the product to melt at the same time, causing the product and the protective film to stick together and cannot be effectively separated; on the other hand, the existing film removal methods can only be applied to products of a single shape and a single height, and cannot be used to remove the film of products that are compatible with multiple shapes and heights, or products with irregular shapes.

[0036] In order to solve the above-mentioned technical problems, an embodiment of the present application proposes a film removal device, which includes a product receiving and clamping mechanism for receiving the film product to be removed and a film cutting mechanism for cutting the protective film of the film product to be removed, the film cutting mechanism including a cutting blade, a first horizontal guide rail assembly for driving the cutting blade to move horizontally, and a vertical guide rail assembly for driving the cutting blade to move vertically; when the cutting blade is used to cut the protective film of the film product to be removed fixed on the product receiving and clamping mechanism, it moves up and down along the vertical guide rail assembly at different heights of the film product to be removed to cut off the protective film at different heights on the film product to be removed. In this way, during the film removal process, the horizontal guide rail assembly cooperates with the vertical guide rail assembly, so that the cutting blade can move horizontally along the product to be removed, and can move up and down along the vertical guide rail assembly as the height of the product to be removed changes, thereby meeting the film removal needs of products to be removed with various shapes, heights, and irregular shapes; in addition, the present application is not limited by the melting point of the product and its protective film. Even if the melting point of the product and its protective film is similar, the cutting blade can be driven by the horizontal guide rail assembly and the vertical guide rail assembly to completely cut off the protective film on the product to be removed, so as to achieve separation of the product and the protective film.

[0037] The technical solutions of the embodiments of the present application are described in detail below through some embodiments. The following embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0038] Figure 1 A film removal device is provided in an embodiment of the present application.

[0039] like Figure 1 As shown, the device includes a product receiving and clamping mechanism 101 for receiving the film-removing product and a film cutting mechanism 102 for cutting the protective film of the film-removing product, and the film cutting mechanism includes a cutting blade, a first horizontal guide rail assembly for driving the cutting blade to move horizontally, and a vertical guide rail assembly for driving the cutting blade to move vertically;

[0040] The cutting blade is used to cut the protective film of the product to be removed fixed on the product receiving and clamping mechanism, and moves up and down along the vertical guide rail assembly at different heights of the product to be removed to cut off the protective film at different heights on the product to be removed.

[0041] When removing the film from the coated product, first fix the product to be removed on the product receiving and clamping mechanism.

[0042] In the initial state, the cutting blade is at the bottom of the vertical rail assembly under the action of gravity, and the distance from the product receiving and clamping mechanism is the smallest. When the product to be removed is moved to the corresponding position on the product receiving and clamping mechanism, the cutting blade will move upward along the vertical rail assembly under the push of the product to be removed until the product to be removed is fixed on the product receiving and clamping mechanism. At this time, the cutting blade is attached to the surface of the product to be removed.

[0043] Then, the film cutting mechanism starts to cut the protective film of the product to be removed. During the cutting process, the first horizontal guide rail assembly drives the cutting blade to move horizontally along the product to be removed. When the product to be removed is an irregular shape such as a curved surface, the cutting blade moves up and down along the vertical guide rail assembly at different heights of the product to be removed. In this way, under the cooperation of the vertical guide rail assembly and the horizontal guide rail assembly, the cutting blade completely cuts off the protective film on the product to be removed.

[0044] The film cutting mechanism involved in the technical solution of the present application is described in detail below through some embodiments.

[0045] The embodiments of the present application do not limit the specific type of the cutting blade.

[0046] In one example, the cutting blade is a serrated blade.

[0047] In another example, the cutting blade is a lancet-shaped blade.

[0048] The embodiment of the present application does not limit the specific structure of the vertical guide rail assembly.

[0049] In a possible implementation, the vertical guide rail assembly includes: a vertical guide rail, a first slider and an elastic assembly, the first slider can move up and down along the vertical guide rail, a first end of the elastic assembly is fixed to the first slider, and a second end of the elastic assembly is fixed to the vertical guide rail;

[0050] A cutting blade is used to drive the first slide block to move up and down along the vertical guide rail when cutting the protective film at different heights of the product to be removed;

[0051] The elastic component is used to generate a downward force on the first slider, so that the first slider presses the cutting blade to closely contact the protective film of the product to be removed.

[0052] In an embodiment of the present application, when cutting the protective film at different heights of the product to be removed, the cutting blade will drive the first slider to move up and down along the vertical guide rail as the height of the product to be removed changes. During the up and down movement of the first slider, the elastic component is always in a compressed state, and because one end of the elastic component is fixed on the first slider, the elastic component in a compressed state will always exert a downward force on the first slider, so that the first slider presses the cutting blade to closely contact the protective film of the product to be removed. In this way, when the cutting blade cuts the protective film of the product to be removed, it is not only affected by the gravity of the first slider and its own gravity, but also by the pressure generated by the elastic component, so that the cutting blade can more closely contact the surface of the product to be removed, achieve a better cutting effect, and prevent the cutting blade from jumping and other undesirable conditions.

[0053] The embodiment of the present application does not limit the specific structure of the elastic component.

[0054] In one example, the elastic component includes a compression spring connecting block, a compression spring limiting block and a compression spring, wherein the compression spring connecting block is fixed on the first sliding block, the compression spring limiting block is fixed on the vertical guide rail, and the compression spring is fixed between the compression spring connecting block and the compression spring limiting block.

[0055] When cutting the protective film at different heights of the product to be removed, the cutting blade will drive the first slider to move up and down along the vertical guide rail as the height of the product to be removed changes. During the up and down movement of the first slider, the first slider will be subjected to the pressure of the compression spring, so that the first slider presses the cutting blade to closely contact the protective film of the product to be removed.

[0056] In another example, the elastic component includes a connecting block, a limiting block and an elastic rubber ball, wherein the connecting block is fixed on the first sliding block, the limiting block is fixed on the vertical guide rail, and the elastic rubber ball is fixed between the connecting block and the limiting block.

[0057] When cutting the protective film at different heights of the product to be removed, the cutting blade will drive the first slider to move up and down along the vertical guide rail as the height of the product to be removed changes. During the up and down movement of the first slider, it will be subjected to the pressure of the elastic rubber ball, so that the first slider presses the cutting blade to closely contact the protective film of the product to be removed.

[0058] In another example, the elastic component includes an air spring, one end of which is fixed to the first slider, and the other end of which is fixed to the vertical guide rail.

[0059] In another possible implementation, the vertical guide rail assembly includes a vertical guide rail, a first slider, an elastic assembly and a transmission assembly. The first slider can move up and down along the vertical guide rail, the first end of the elastic assembly is fixed on the first slider, and the second end of the elastic assembly is fixed on the vertical guide rail; the transmission assembly is fixed on the first slider and is fixedly connected to the cutting blade.

[0060] The cutting blade is used to drive the transmission assembly to move up and down when cutting the protective film at different heights of the product to be removed, thereby driving the first slider to move up and down along the vertical guide rail;

[0061] The elastic component is used to generate a downward force on the first slider, so that the first slider presses the cutting blade to closely contact the protective film of the product to be removed.

[0062] In the embodiment of the present application, a transmission assembly is provided in the vertical guide rail assembly for driving the cutting blade to rotate at high speed. On the one hand, the cutting blade is driven to rotate at high speed by the transmission assembly, thereby improving the cutting speed and cutting effect. On the other hand, all parts of the blade of the entire blade can dynamically participate in the operation, thereby increasing the utilization rate of the entire blade, and allowing the blade to dissipate heat in time when operating while other parts are operating, thereby greatly extending the service life of the blade and reducing the time and cost of maintaining the cutting blade.

[0063] The embodiment of the present application does not limit the specific structure of the above-mentioned transmission assembly.

[0064] In one example, the transmission assembly includes a high-speed motor, a transmission wheel, and a blade transmission shaft connected to the transmission wheel through a transmission belt, and a cutting blade is arranged on the blade transmission shaft;

[0065] The high-speed motor is used to transmit power to the cutting blade through the transmission wheel, the transmission belt and the blade transmission shaft, driving the cutting blade to rotate at a high speed so that the cutting blade cuts off the protective film of the product to be removed.

[0066] In another example, the transmission assembly includes a high-speed motor and a cutting blade mounted on an end surface of an output shaft of the motor, and the high-speed motor is used to drive the cutting blade to rotate at a high speed.

[0067] In another example, the transmission assembly further includes a motor fixing plate for fixing the high-speed motor, the motor fixing plate is fixed on the first slider, the output shaft of the motor passes through the motor fixing plate and is connected to the transmission wheel, the transmission wheel is connected to the blade transmission shaft through a transmission belt, the cutting blade is fixed on the blade transmission shaft, and is self-lockingly fastened by a reverse thread nut. The high-speed motor rotates at high speed, and transmits power to the cutting blade through the transmission wheel, the transmission belt and the blade transmission shaft, driving the cutting blade to rotate at high speed, so that the cutting blade can quickly cut off the protective film of the film product to be removed.

[0068] The embodiment of the present application does not limit the specific structure of the horizontal guide rail assembly.

[0069] In some embodiments, the horizontal guide rail assembly includes: a first horizontal guide rail, a second slider disposed on the first horizontal guide rail, and a first driving assembly, wherein the second slider is fixedly connected to the vertical guide rail;

[0070] The first driving assembly is used to drive the vertical guide rail assembly to move horizontally along the first horizontal guide rail, thereby driving the cutting blade to move horizontally along the film-removing product.

[0071] In some embodiments, the horizontal guide rail assembly includes a horizontal guide rail fixing plate supported and fixed on the workbench, a first horizontal guide rail fixed on the horizontal guide rail fixing plate, a second slider disposed on the first horizontal guide rail, and a first driving assembly, wherein the second slider is fixedly connected to the vertical guide rail;

[0072] The first driving assembly is used to drive the vertical guide rail assembly to move horizontally along the first horizontal guide rail, thereby driving the cutting blade to move horizontally along the product to be removed.

[0073] The embodiment of the present application does not limit the specific structure of the first driving component.

[0074] In one example, the first driving assembly includes a left-right moving cylinder, which is fixed to a left-right moving cylinder fixing plate through a connecting block, and the extended end of the left-right moving cylinder is connected to a vertical guide rail or a vertical guide rail fixing plate through a floating joint and a connecting block;

[0075] The left-right moving cylinder is used to drive the vertical guide rail assembly to move horizontally along the horizontal guide rail, thereby driving the cutting blade to move horizontally along the surface of the product to be removed.

[0076] In another example, the first driving assembly includes a left-right moving electric cylinder, which is fixed on a fixed plate, and an extended end of the left-right moving electric cylinder is connected to a vertical guide rail or a vertical guide rail fixed plate;

[0077] The left-right moving electric cylinder is used to drive the vertical guide rail assembly to move horizontally along the horizontal guide rail, thereby driving the cutting blade to move horizontally along the surface of the product to be removed.

[0078] In a possible implementation, the film cutting mechanism further includes a high-pressure air needle, the needle opening of which is directly opposite to the contact point between the cutting blade and the product to be removed, and the high-pressure air needle is used to spray high-pressure air toward the product to be removed so as to separate the severed protective film from the product to be removed.

[0079] In the embodiment of the present application, after the cutting blade cuts the protective film, the high-pressure air ejected from the high-pressure air jet needle blows up the protective film of the product to be removed, so that the cut protective film is separated from the product to be removed. In this way, the product to be removed, which has been cut by the cutting blade and blown up by the high-pressure air jet needle, can more efficiently and completely separate the protective film from the product during the subsequent separation operation.

[0080] like Figure 1 As shown, in one practicable manner, the film cutting mechanism includes a horizontal guide rail assembly, a vertical guide rail assembly, a transmission assembly and a sawtooth blade.

[0081] The horizontal guide rail assembly comprises a horizontal guide rail fixing plate 1 , a first horizontal guide rail 2 , a second sliding block arranged on the first horizontal guide rail 2 , a left-right moving cylinder fixing block 12 and a left-right moving cylinder 13 .

[0082] Among them, the horizontal guide rail fixing plate 1 is supported and fixed on the workbench, the first horizontal guide rail 2 is fixed on the horizontal guide rail fixing plate 1, and the left and right moving cylinder 13 is fixed on the left and right moving cylinder fixing plate through the left and right moving cylinder fixing block 12.

One end of the compression spring connecting block 3 is fixed on the motor fixing plate 9, and the other end is squeezed with the compression spring 4. The compression spring 4 is fixed on the compression spring limit block 5 by the compression spring fixing screw 15. The compression spring limit block 5 is fixed on the vertical guide rail fixing plate 10. The motor fixing plate 9 moves up and down and is subject to the pressure of the compression spring 4. The high-speed motor 8 is fixed on the motor fixing plate 9, and transmits power to the serrated blade transmission shaft 16 through the combination of the transmission wheel 7 and the transmission belt 6 (chain). The serrated blade 17 is fixed on the serrated blade transmission shaft 16 and is self-lockingly fastened by the anti-thread nut. The serrated blade 17 rotates at high speed and acts on the product 14 to be defilmed. The high-pressure air needle 18 is installed on one side of the sawtooth blade 17, and the needle port is facing the contact point between the sawtooth blade 17 and the product to be defilmed 14. The extended end of the left and right moving cylinder 13 is connected to the vertical guide rail fixing plate 10 through a floating joint and a connecting block, thereby driving the sawtooth blade to move forward and backward.

[0085] Figure 2 A partial close-up view of a film cutting mechanism provided in an embodiment of the present application.

[0086] like Figure 2 As shown, the high-pressure air needle 18 is installed on one side of the sawtooth blade 17, and the needle opening is facing the contact point between the sawtooth blade 17 and the product 14 to be defilmed.

[0087] The protective film of some coated products has a certain stickiness, or due to static electricity, the protective film and the product are stuck together, making them difficult to peel off. Existing methods of laser cutting and separation after crushing cannot solve this problem. In the embodiment of the present application, after the serrated blade cuts the protective film of the product to be removed, the protective film on the product can be torn off along the blade edge, and then the high-pressure air needle sprays high-pressure air to completely peel off the protective film from the product, thereby separating the product from the protective film. In this way, during the film removal process, even if the protective film and the product are stuck together, the strong force generated by the cooperation of the serrated blade and the high-pressure air needle can cut off the protective film stuck to the product and peel off the product.

[0088] The above introduces the specific structure and working process of the film cutting mechanism involved in the film removal device. The following describes in detail the product receiving and clamping mechanism involved in the technical solution of the present application through some embodiments.

[0089] The product receiving and clamping mechanism involved in this application includes but is not limited to the following implementation methods.

[0090] Method 1, the above-mentioned product receiving and clamping mechanism includes a left support plate and a right support plate arranged opposite to each other, and a positioning station is provided on the left support plate and the right support plate, and the positioning station is used to position the product to be film-removed.

[0091] In some embodiments, the positioning station includes a film cutting station, which is used to fix the product to be film-removed when the cutting blade cuts the protective film of the product to be film-removed.

[0092] In some embodiments, the above-mentioned workstations include a loading and positioning workstation and a film cutting workstation. The loading and positioning workstation is used to fix the product to be film-cut.

[0093] In the embodiment of the present application, the film-removing product is first transported to the loading and positioning station and the film-cutting station; when the cutting blade completes the cutting of the protective film of the film-removing product at the film-cutting station, the protective film of the film-removing product is removed after the cutting, and at the same time, the film-removing product at the loading and positioning station is transferred to the film-cutting station so that the cutting blade can perform the next cutting operation, and the film-removing product in the barrel is transferred to the loading and positioning station. In this way, during the film removal process, two stations are set in the product receiving and clamping mechanism to improve the loading efficiency, thereby improving the film removal efficiency.

[0094] In some embodiments, the above-mentioned workstations include a loading and positioning workstation, a film cutting workstation and a product protective film separation workstation, and the product protective film separation workstation is used to position the product to be removed from the film.

[0095] In the embodiment of the present application, the film-removing product is first transported to the loading and positioning station and the film-cutting station; when the cutting blade has cut off the protective film of the film-removing product at the film-cutting station, the film-removing product at the film-cutting station is transferred to the product protective film separation station to remove the protective film of the film-removing product after the cutting is completed, and the film-removing product at the loading and positioning station is transferred to the film-cutting station so that the cutting blade can perform the next cutting operation, and the film-removing product in the barrel is transferred to the loading and positioning station. In this way, during the film removal process, three stations are set in the product receiving and clamping mechanism to improve the efficiency of loading and meet the needs of different operation processes.

[0096] The embodiment of the present application does not impose any specific limitation on the shape of the workstation.

[0097] In a possible implementation, the workstation is a rectangular opening.

[0098] When the product to be defilmed is transported to the work station, the rectangular opening positions the product to be defilmed in the opening.

[0099] In another possible implementation, the workstation is a U-shaped opening.

[0100] It should be noted that the products to be defilmed have various shapes, for example, diamond-shaped film products, square-shaped film products, cylindrical-shaped film products, etc. In order to enable the defilming device to defilm products of various shapes and heights, when designing the workstation, the workstation needs to be able to fix products of various shapes. When designing the workstation, the embodiment of the present application combines the shape characteristics of the product and designs the workstation as a U-shaped opening that integrates a straight structure and a curved structure, and the diameter of the bottom end of the U-shaped opening meets the size requirements of the film-coated products of various shapes. Compared with workstations of other shapes such as V-shaped openings, rectangular openings, and semicircular openings, the U-shaped opening can fix the bottoms of various shapes of film-coated products such as cylindrical film-coated products, diamond-shaped film-coated products, and square film-coated products in the U-shaped opening to achieve better positioning effects. At the same time, if the U-shaped openings currently opened on the left support plate and the right support plate are not suitable for the size of the product to be defilmed, for example, the product to be defilmed is thick and cannot be fixed in the U-shaped groove, a set of U-shaped workstations with larger diameters can be replaced to meet the needs of the product to be defilmed.

[0101] Mode 2: the above-mentioned product receiving and clamping mechanism includes a clamping assembly, which is used to clamp the product to be defilmed to prevent the product to be defilmed from moving and / or turning over on the product receiving and clamping mechanism.

[0102] The clamping assembly can clamp the product to be film-removed from the front and rear ends, can also clamp the product to be film-removed from the bottom, and can also clamp the product to be film-removed from both sides, and the present application does not impose specific restrictions on this.

[0103] The embodiment of the present application does not limit the specific structure of the clamping assembly.

[0104] In one example, the clamping assembly includes: a left vertical support plate and a right vertical support plate fixed on a workbench and arranged opposite to each other, a front clamping cylinder fixed on the left vertical support plate, a front clamping block connected to the protruding end of the front clamping cylinder, a rear clamping cylinder fixed on the right vertical support plate, and a rear clamping block connected to the rear clamping cylinder, wherein slots are provided above the front clamping block and the rear clamping block so that when the cutting blade moves to the slots at both ends, the cutting of the protective film at both ends of the film product to be removed is completed.

[0105] A front clamping cylinder is used to drive the front clamping block to move toward the product to be de-filmed when the product to be de-filmed is located in the product receiving clamping mechanism, so that the front clamping block fixes the first end of the product to be de-filmed;

[0106] The rear clamping cylinder is used to drive the rear clamping block to move toward the product to be removed when the product to be removed is located in the product receiving clamping mechanism, so that the rear clamping block fixes the second end of the product to be removed.

[0107] In the embodiment of the present application, on the one hand, the front and rear clamping cylinders can drive the front and rear clamping blocks connected to the front and rear clamping cylinders to move horizontally, thereby adjusting the distance between the front and rear clamping blocks to meet the film removal requirements of products of different lengths to be removed. On the other hand, the front and rear clamping cylinders and the front and rear clamping blocks connected to the front and rear clamping cylinders are used to fix the two ends of the product to be removed to prevent the product to be removed from moving forward and backward on the product receiving clamping mechanism, so that in the subsequent cutting operation, the cutting blade can completely cut off the protective film of the product to be removed and improve the efficiency of film removal. In addition, by providing a slot above the front clamping block and the rear clamping block, the clamping assembly can clamp the product tightly without affecting the cutting and film removal operation.

[0108] In another example, the clamping assembly includes: a left vertical support plate and a right vertical support plate fixed on the workbench and arranged opposite to each other, a front clamping cylinder fixed on the left vertical support plate, a front clamping block connected to the protruding end of the front clamping cylinder, a rear clamping cylinder fixed on the right vertical support plate, a rear clamping block connected to the rear clamping cylinder, and a flip clamping assembly, wherein slots are provided above the front clamping block and the rear clamping block so that when the cutting blade moves to the slots at both ends, the protective film at both ends of the product to be removed is cut. The flip clamping assembly is used to flip the product to be removed to a predetermined angle and keep it at the predetermined angle to prevent the product to be removed from flipping on the product receiving clamping mechanism.

[0109] Mode 3, the above-mentioned product undertakes the clamping mechanism including a positioning station and a clamping assembly.

[0110] Figure 3 A structural schematic diagram of a product receiving and clamping mechanism provided in an embodiment of the present application.

[0111] like Figure 3 As shown, the product receiving and clamping mechanism includes a left support plate 19 and a right support plate 20 that are relatively arranged. The left support plate 19 and the right support plate 20 are provided with a loading and positioning station 21, a film cutting station 22 and a product protective film separation station 23 for positioning the product to be removed from the film, as well as a clamping assembly arranged at the film cutting station.

[0112] The clamping assembly includes a left vertical support plate 24 and a right vertical support plate 25 fixed on the workbench and arranged opposite to each other, a front clamping cylinder 26 fixed on the left vertical support plate 24, a front clamping block 27 connected to the protruding end of the front clamping cylinder, a rear clamping cylinder 28 fixed on the right vertical support plate 25, a rear clamping block 29 connected to the rear clamping cylinder, and a flip clamping cylinder 30, wherein slots are provided above the front clamping block 27 and the rear clamping block 29 so that when the cutting blade moves to the slots at both ends, the protective film at both ends of the film-removing product is cut. The flip clamping cylinder 30 is used to flip the film-removing product to a predetermined angle and keep it at the predetermined angle to prevent the film-removing product from flipping on the product receiving clamping mechanism.

[0113] The above introduces the specific structure and working process of the product receiving and clamping mechanism involved in the film removal device. The following describes in detail the product protective film separation mechanism involved in the technical solution of the present application through some embodiments.

[0114] In some embodiments, the above-mentioned film removal device further comprises a product protective film separation mechanism for removing the product protective film, and the product protective film separation mechanism comprises a product suspension component and a separation component;

[0115] A product suspension component is used to suspend the product to be removed after the protective film of the product to be removed is cut off by the cutting blade;

[0116] The separation component is used to blow the protective film on the suspended product to be removed away from the product, so as to separate the product from the protective film.

[0117] In an embodiment of the present application, when separating the product from the protective film, the product to be removed with the protective film cut off is first suspended in the air to completely expose the surface of the product to be removed. In this way, when the product and the protective film are subsequently separated, the high-pressure air generated by the separation component can act on the entire product to be removed, so that the protective film on the product to be removed is acted upon by the high-pressure air and separated from the product.

[0118] The embodiments of the present application do not limit the specific structure of the suspended components of the above-mentioned products.

[0119] In a possible implementation, the product suspension assembly includes a product limit block, a product pressing block arranged opposite to the product limit block, and a second driving assembly;

[0120] The second driving assembly is used to drive the product pressing block to move toward the product to be removed when the product to be removed is located between the product limiting block and the product pressing block, so that the product to be removed is fixed between the product limiting block and the product pressing block.

[0121] In order to make the film removal device suitable for the needs of products to be removed of different lengths, in an embodiment of the present application, a product pressing block and a second driving component that drives the product pressing block to move horizontally are provided in the product suspension component, so that the product suspension component can automatically adjust the distance between the product limit block and the product pressing block according to the length of the product to be removed, so as to meet the film removal needs of products to be removed of different lengths.

[0122] In another possible implementation, the product suspension assembly includes a first pressing block and a second pressing block that are relatively arranged, a first cylinder for driving the first pressing block to move horizontally, and a second cylinder for driving the second pressing block to move horizontally.

[0123] When the product to be defilmed is transported between the first pressing block and the second pressing block, the first cylinder and the second cylinder respectively drive the first pressing block and the second pressing block to move toward the middle product to be defilmed until the product to be defilmed is fixed between the first pressing block and the second pressing block.

[0124] The embodiment of the present application does not limit the specific structure of the above-mentioned separation component.

[0125] In one example, the separation component includes a first high-pressure air connector disposed on the upper side of the suspended product to be film-removed, and the first high-pressure air connector is used to spray high-pressure air toward the product to be film-removed to separate the protective film from the product.

[0126] Existing film removal solutions generally use hot air flow to blow the protective film away from the product. In this way, when the melting point of the product is lower than that of the protective film, or when the melting points are close, the hot air flow will cause the product and the protective film to stick together, making it impossible to effectively separate the product and the protective film.

[0127] In the embodiment of the present application, the high-pressure air generated is sprayed onto the suspended product to be defilmed through the high-pressure air joint, and the high-pressure air acts on the disconnected protective film, so that the protective film is separated from the product. On the one hand, this separation scheme does not generate heat, and is therefore not limited by the melting point of the protective film and the product; on the other hand, the high-intensity pressure generated by the high-pressure air acting on the disconnected protective film can quickly separate the product from the protective film, thereby improving the efficiency of product defilming.

[0128] In another example, the separation component also includes a second high-pressure air connector arranged on the front or rear side of the suspended product to be removed; the second high-pressure air connector is used to spray high-pressure air at the detached protective film to blow the detached protective film into the protective film collection box.

[0129] In the embodiment of the present application, the high-pressure air joint located above the product to be removed cooperates with the product to be removed located at the rear side of the product to be removed, so that the protective film separated from the product can be automatically transferred to the protective film collection box. In this way, manpower is liberated during the product removal process and the product removal efficiency is improved.

[0130] In some embodiments, the product protective film separation mechanism further includes a third driving component, which is used to move the product to a product collection box after the product and the protective film are separated.

[0131] In the embodiment of the present application, by automatically pushing the product after film removal into the product collection box, manpower is freed up and the film removal efficiency of the product is improved.

[0132] Figure 4 A schematic structural diagram of a product protective film separation mechanism provided in an embodiment of the present application.

[0133] like Figure 4 As shown, the product protection film separation mechanism includes a product suspension component, a separation component and a third driving component.

[0134] Among them, the product suspension component includes: a product limit block 33, a product pressing cylinder 34, a product pressing cylinder fixing plate 35 and a product pressing block 36; the third driving component includes: a product pushing cylinder 31 and a product pushing cylinder fixing plate 32.

[0135] The product pushing cylinder fixing plate 32 and the product pressing cylinder fixing plate 36 are supported and fixed on the workbench and are arranged opposite to each other; the product pushing cylinder 31 is fixed on the product pushing cylinder fixing plate 32, and the product pressing cylinder 34 is fixed on the product pressing cylinder fixing plate 35. The protruding end of the product pressing cylinder 34 is installed with a product pressing block 36, and the product limit block 33 is fixed on the product pushing cylinder fixing plate 32.

[0136] When the product 38 to be defilmed is transported between the product limit block 33 and the product pressing block 36 , the product pressing cylinder 34 drives the product pressing block 36 to move toward the product to be defilmed until the product to be defilmed is suspended and fixed between the product limit block 33 and the product pressing block 36 .

[0137] The separation assembly includes a first high-pressure air connector 37 fixed above the suspended film-removing product, and a second high-pressure air connector fixed at the rear side of the suspended film-removing product.

[0138] When the product to be film removed is suspended and fixed between the product limit block 33 and the product pressing block 36, the first high-pressure air connector 37 sprays high-pressure air toward the product to be film removed, so that the broken protective film falls off the product, and the second high-pressure air connector sprays high-pressure air forward, so that the fallen protective film is blown into the protective film collection box.

[0139] The third driving assembly includes a product pushing cylinder 31 fixed on a product pushing cylinder fixing plate 32. When the protective film on the product is completely separated from the product, the product pressing cylinder 34 extends back, driving the product pressing block 36 to move away from the product. After the film is removed, the product loses its positioning function and falls off to the front side of the product pushing cylinder 31. The product pushing cylinder 31 extends forward to push the product after the film is removed into the product collection box.

[0140] In the embodiment of the present application, the product pressing block 36 is driven to move by the product pressing cylinder 34, and the product to be removed is suspended and fixed between the product limit block 33 and the product pressing block 36; high-pressure air is sprayed to the product to be removed through the first high-pressure air joint 37 fixed above the suspended product to be removed, so that the disconnected protective film is completely separated from the product; the detached protective film is blown into the protective film collection box through the second high-pressure air joint fixed on the rear side of the suspended product to be removed; the product after film removal is pushed into the product collection box by the product pushing cylinder 31, thereby realizing automatic film removal of the product to be removed, automatic separation of the product and the protective film, and automatic transfer of the product and the protective film to the corresponding collection box, making the product removal process more efficient.

[0141] Figure 5 A schematic diagram of separating a product protective film provided in an embodiment of the present application.

[0142] like Figure 5 As shown, after the protective film on the product is removed, the product pressing cylinder 34 extends backward, driving the product pressing block 36 to move backward, and the product after film removal falls to the product receiving clamping mechanism, and the product pushing cylinder 31 extends forward to push the product after film removal into the product collection box.

[0143] The above introduces the specific structure and working process of the product protection film separation mechanism involved in the film removal device. The following describes in detail the product conveying mechanism involved in the technical solution of the present application through some embodiments.

[0144] In some embodiments, the film removal device further comprises a product transport mechanism, which is used to transport the product to be film removed to a corresponding station on the product receiving and clamping mechanism.

[0145] The product handling mechanism comprises a product receiving plate for receiving the film-removing product, a second horizontal guide rail assembly and a receiving drive assembly;

[0146] The second horizontal guide rail assembly is used to drive the product receiving plate to move horizontally so as to move the product receiving plate to a corresponding work station;

[0147] The receiving drive assembly is used to drive the product receiving plate to move vertically, so as to transfer the product to be defilmed on the work station to the product receiving plate, or to transfer the product to be defilmed on the product receiving plate to the work station.

[0148] In some embodiments, at least one group of openings is opened on the product receiving plate, and the second horizontal guide rail assembly drives the product receiving plate to move to the corresponding work station. At this time, the opening is opposite to the corresponding work station on the product receiving and clamping mechanism, and is located directly below the product to be defilmed on the work station; then, the receiving drive assembly drives the product receiving plate to move upward, so that the product to be defilmed on the work station of the product receiving and clamping mechanism is fixed in the opening opened in the product receiving plate.

[0149] The embodiment of the present application does not limit the specific structure of the second horizontal guide rail assembly.

[0150] In one example, the second horizontal guide rail assembly includes a fourth drive assembly, a second horizontal guide rail, and a third slider disposed on the second horizontal guide rail.

[0151] Among them, the receiving drive component is fixed on the third sliding block, and the product receiving plate is fixed on the receiving drive component.

[0152] The fourth driving assembly is used to drive the third slider to move horizontally, so that the receiving driving assembly fixed on the third slider and the product receiving plate fixed on the receiving driving assembly move horizontally until the product receiving plate moves to the corresponding station of the product receiving clamping mechanism.

[0153] In another example, the second horizontal guide rail assembly includes a second horizontal guide rail, a third slider disposed on the second horizontal guide rail, a fixing plate fixed on the third slider, and a fourth driving assembly connected to the fixing plate, wherein the fourth driving assembly is fixed on the left support plate 19.

[0154] Among them, the receiving drive component is fixed on the fixed plate, and the product receiving plate is fixed on the receiving drive component.

[0155] Figure 6 A schematic structural diagram of a product handling mechanism provided in an embodiment of the present application.

[0156] like Figure 6As shown, the product handling mechanism includes a second horizontal guide rail 39, a third slider disposed on the second horizontal guide rail 39, a cylinder fixing plate 40 (or fixing plate) fixed on the third slider, a forward and backward moving cylinder 42 (or a fourth driving assembly) fixed on the left support plate 19, an upper and lower receiving cylinder 41 (or a receiving driving assembly) fixed on the cylinder fixing plate 40, a product receiving plate 43 installed on the protruding ends of the upper and lower receiving cylinders 41, and a fixing block. Among them, a fisheye joint is provided at the protruding end of the forward and backward moving cylinder 42, and the fisheye joint is connected to the cylinder fixing plate 40, so that the forward and backward moving cylinder 42 drives the cylinder fixing plate 40 to move forward and backward. Two groups of U-shaped openings are provided on the product receiving plate 43, and the distance between the two groups of U-shaped openings is consistent with the distance between the upper stations of the product receiving clamping mechanism.

[0157] When the product handling mechanism is working, for example, the product handling mechanism needs to carry the product to be removed from the loading and positioning station on the product receiving and clamping mechanism to the film cutting station, and to carry the product to be removed from the film cutting station to the product protective film separation station. First, the forward and backward moving cylinder 42 drives the product receiving plate 43 to move horizontally until the two groups of U-shaped openings on the product receiving plate 43 are aligned with the loading and positioning station and the film cutting station respectively; then, the protruding ends of the upper and lower receiving cylinders 41 extend upward, driving the product receiving plate 43 installed on the protruding ends of the upper and lower receiving cylinders 41 to move upward, so that the product to be removed from the two stations is transferred to the two groups of U-shaped openings of the product receiving plate 43, and the protruding ends of the upper and lower receiving cylinders 41 continue to extend upward until the product to be removed is moved out of the loading and positioning station. Then, the forward and backward moving cylinder 42 drives the product receiving plate 43 to move horizontally until the two groups of U-shaped openings on the product receiving plate 43 are respectively aligned with the film cutting station and the product protective film separation station. At this time, the protruding ends of the upper and lower receiving cylinders 41 extend back, driving the product receiving plate 43 installed on the protruding ends of the upper and lower receiving cylinders 41 to move downward until the products to be removed from the two groups of U-shaped openings of the product receiving plate 43 are transferred to the film cutting station and the product protective film separation station, completing one product handling work.

[0158] The above introduces the specific structure and working process of the product handling mechanism involved in the film removal device. The following describes in detail the automatic feeding mechanism involved in the technical solution of the present application through some embodiments.

[0159] In some embodiments, the above-mentioned film removal device also includes an automatic loading mechanism for transporting the product to be film removed to the product receiving and clamping mechanism.

[0160] FIG. 7 is a schematic diagram of the structure of an automatic feeding mechanism provided in an embodiment of the present application.

[0161] like Fig. 7A and 7B As shown, the embodiment of the present application adopts a push plate structure for loading.

[0162] The automatic feeding mechanism can transfer the products to be defilmed to the product receiving and clamping mechanism one by one, thereby realizing automatic feeding one by one.

[0163] Specifically, Fig. 7A and 7B As shown, the automatic feeding mechanism includes: a material barrel 44, a feeding fixed plate 45, a feeding movable plate 46, a left fixed plate 47, a right fixed plate 48, a pushing cylinder 49, a feeding cylinder 50, a feeding guide rail 51, a linear guide rail 52, a pushing plate 53 and a floating plate 54.

[0164] The material barrel 1 is located in the front and is used to load the products to be defilmed. It can load more than 1000 pieces at a time. The products do not need to be placed in order. The push plate mechanism can realize the placement of products in the specified direction after taking the materials one by one. The loading fixed plate 45 is fixed on the left fixed plate 47 and fixed on the workbench through the fixed rib plate; the loading movable plate 46 is fixed on the floating plate 54, the floating plate 54 is fixed on the linear guide rail 52, the linear guide rail is fixed to the right fixed plate 48 of 52, and the right fixed plate 48 is fixed on the workbench.

[0165] Among them, a feeding cylinder 50 is installed on the right fixed plate 48, and the extending rod of the feeding cylinder 50 is installed with a fisheye joint, which is connected to the floating plate 54; the feeding cylinder 50 drives the floating plate 54 and the feeding movable plate 45 to move linearly along the direction of the linear guide rail.

[0166] During the automatic loading process, the product to be defilmed is first moved into the barrel 1. Because the bottom of the barrel 1 is inclined to the ground, the product to be defilmed will slide to the bottom along the slope under the action of gravity. In the initial state, the loading movable plate 46 is located at the bottom of the barrel 1, and the product to be defilmed moves along the slope onto the loading movable plate 46. The loading cylinder 50 drives the floating plate 54 and the loading movable plate 46 to move upward, thereby driving a piece of the product to be defilmed to move upward to the first loading fixed plate 45. Then, the loading cylinder 50 drives the floating plate 54 and the loading movable plate 46 to move downward, so that the loading movable plate 46 returns to its original position, and the next product to be defilmed is moved onto the loading movable plate 46. The loading cylinder 50 drives the floating plate 54 and the loading movable plate 46 to move upward again, so that the product to be defilmed on the loading movable plate 46 is transferred to the first loading fixed plate. At the same time, the first loading fixed plate 45 is also transferred to the next fixed plate. Therefore, during the loading process, the loading movable plate cooperates with the loading fixed plate, so that every time the loading movable plate moves downward, a product to be defilmed in the material barrel is moved to the loading movable plate, and every time the loading movable plate moves upward, the product to be defilmed on the loading movable plate is transferred to the next loading fixed plate. In this way, automatic loading is realized, so that the product to be defilmed is transferred to the feeding guide rail 51. The push plate 53 is fixed on the slider of the push cylinder 49, and the end of the push plate 53 is located on the feeding guide rail 51. After the top loading movable plate completes the action, the product is sent to the feeding guide rail 51, and the push plate 51 is located at the end of the product to be defilmed. As the push cylinder 49 moves forward, the push plate 51 sends the product to be defilmed to the front product receiving clamping mechanism to complete the loading action, and the cycle is repeated to realize the fully automatic and continuous loading of the product to be defilmed.

[0167] The following is an example of a film removal device including an automatic feeding mechanism, a product receiving and clamping mechanism, a film cutting mechanism, and a product protective film separation mechanism. Figure 1 As shown in FIG. 7 , the technical solution of the present application is explained, wherein the structural composition of the automatic feeding mechanism, the product receiving and clamping mechanism, the film cutting mechanism and the product protective film separation mechanism can refer to the description of the above embodiments and will not be repeated here.

[0168] First, as shown in FIG7 , the feeding cylinder 50 in the automatic feeding mechanism drives the feeding movable plate 46 to move upward along the linear guide rail 52 each time, and the product to be defilmed can be transferred to the feeding fixed plate 45 at the next height. Multiple groups of feeding movable plates 46 and feeding fixed plates 45 cooperate to transfer the product to be defilmed to the feeding guide rail 51. The push cylinder 49 is used to drive the push plate 53 to transfer the product to be defilmed located on the feeding guide rail 51 to the feeding positioning station in the product receiving and clamping mechanism when the product to be defilmed is transferred to the feeding guide rail 51.

[0169] like Figure 3 As shown, the automatic feeding mechanism pushes the product to be defilmed to the feeding positioning station 21.

[0170] Among them, when the pushing plate 53 transfers the product to be defilmed to the loading positioning station 21, the position of the pushing plate 53 is fixed. Therefore, the relative position of one end of the product to be defilmed and the product receiving clamping mechanism is fixed. In the subsequent clamping operation, the clamping component at one end only needs to move a fixed distance each time to fix one end of the product to be defilmed.

[0171] A material detection device 55 , for example, a material arrival optical fiber sensor, which is in communication with the processor, is disposed at the front end of the loading and positioning station 21 .

[0172] The material detection device is used to determine the quantity of the products to be de-filmed at the loading and positioning station, and send the quantity information of the products to be de-filmed to the processor;

[0173] The processor is used to control the alarm device to send out an alarm message when it is detected that the number of products to be defilmed is greater than a first preset value, so as to prompt relevant personnel to move the products to be defilmed away from the loading and positioning station.

[0174] The processor is also used to control the automatic feeding mechanism to transport the products to be defilmed to the feeding positioning station when it is detected that the number of the products to be defilmed is less than a first preset value.

[0175] The product handling mechanism transports the film-removing product at the loading and positioning station 21 to the film-cutting station 22. On the product receiving and clamping mechanism, the film-cutting station 22 is used to clamp the film-removing product to prevent the product from moving and flipping. The front clamping block 27 and the rear clamping block 29 have V-shaped openings with rough surfaces. The front clamping cylinder 26 and the rear clamping cylinder 28 are respectively fixed on the left support plate 24 and the right support plate 25. The protruding ends of the front clamping cylinder 26 and the rear clamping cylinder 28 move forward, driving the front clamping block 27 and the rear clamping block 29 to move forward, thereby clamping the film-removing product front and back. The flip clamping cylinder 30 is used to clamp the film-removing product. At this time, the clamping limit generated by the front clamping block 27, the rear clamping block 29, the flip clamping cylinder 30, and the support plate station groove can firmly fix the film-removing product. Among them, there are slots on the front clamping block 27 and the rear clamping block 29, which can meet the requirements of tightly clamping the product without affecting the cutting operation. After the cutting and film removal is completed, each clamping mechanism is released in turn, and the product handling mechanism will transfer the film-removed product after cutting to the product protective film separation station 23.

[0176] like Figure 6As shown, the function of the product transport mechanism is to transfer the product to be defilmed from the loading and positioning station 21 in the product receiving and clamping mechanism to the film cutting station 22, and to transfer the product from the film cutting station 22 to the product protective film separation station 23. The forward and backward moving cylinder 42 in the product transport mechanism is installed on the left support plate of the product receiving and clamping mechanism through a fixed block. The extended end of the forward and backward moving cylinder 42 is provided with a fisheye joint, which is connected to the cylinder fixing plate 40. The forward and backward movement of the forward and backward moving cylinder 42 can drive the product receiving plate 43 to move forward and backward, thereby driving the product to be defilmed to move forward and backward.

[0177] The working principle of the product handling mechanism is as follows: There are two sets of U-shaped openings on the product receiving plate, and the distance between the two sets of openings is consistent with the distance between the U-shaped openings on the left and right support plates in the product receiving clamping mechanism. When the equipment is in working state, the product is moved to the loading and positioning station 21 by the automatic feeding mechanism, and the film cutting station 22 has the film-cutting product completed in the previous action. The two sets of openings on the product receiving plate are directly below the product, and the upper and lower receiving cylinders 41 move upward to lift the product to the U-shaped opening that is separated from the left support plate 19 and the right support plate 20. In the next step, the forward and backward moving cylinders act to move the product forward by the distance between the two openings, and the upper and lower receiving cylinders 41 descend, and the product originally in the loading and positioning station 21 is transferred to the film cutting station 22, and the product originally in the film cutting station 22 is transferred to the product protective film separation station 23. After the product receiving plate descends, it is separated from the product, and the forward and backward moving cylinders extend back to drive the product receiving plate back to the loading and positioning station and the film cutting station. The above steps are repeated to realize the continuous automatic product handling operation process.

[0178] like Figure 1 As shown, when the film-removing product is placed in the film-cutting station, the product receiving and clamping mechanism firmly fastens the film-removing product, and the high-speed motor 8 in the film-cutting mechanism is started to drive the serrated blade 17 to rotate at high speed, and the cylinder 13 is moved left and right to extend forward. The high-speed rotating serrated blade 17 acts on the surface of the film-removing product to cut the protective film. After the serrated blade 17 cuts the protective film, the high-pressure air sprayed by the high-pressure air needle 18 blows the protective film on the film-removing product to be separated from the product. When the serrated blade 17 cuts the protective film at different heights on the film-removing product, it moves up and down along the vertical guide rail 11, and the compression spring 4 has an adjustable pre-pressure on the serrated blade 17, so that the serrated cutter is in close contact with the surface of the film-removing product to be removed, so as to prevent the serrated cutter 17 from jumping and other undesirable conditions. This structure has good compatibility with film-removing products of different shapes and curved surfaces, and can also efficiently peel and remove the protective film when the melting point of the protective film is close to that of the product.

[0179] like Figure 4As shown, after the product is cut and the film is removed, the product to be removed is transported to the product protective film separation station by the product transport mechanism. The product protective film separation mechanism completely separates the product from the protective film and transfers the product and the protective film to the corresponding collection box.

[0180] Working process: After the product handling mechanism moves forward to the product protective film separation station 23, the product is located between the product pressing block 36 and the product limit block 33. The product pressing cylinder 34 drives the product pressing block to extend forward and presses the product to be removed onto the product limit block 33. The product receiving plate 43 in the product handling mechanism moves downward. At this time, the product is in a suspended state. The high-pressure air connector 37 sprays high-pressure air to blow the cut protective film away from the product and send it to the protective film collection box through the track. The product pressing cylinder 34 extends backward, and the product falls to the product protective film separation station 23. The product pushing cylinder 31 extends forward to push the columnar product into the columnar product collection box. At this point, the product and the protective film are completely separated.

[0181] To summarize, through the technical solution of the present application, the automatic loading mechanism can take out the products to be removed from the barrel one by one, and transport them to the loading station of the product receiving and clamping mechanism; the product transporting mechanism transports the products to be removed at the loading station to the film cutting station, and the film cutting mechanism cuts off the protective film of the products to be removed at the film cutting station, and peels off the broken protective film from the products through a high-pressure air needle; then, the product transporting mechanism transports the products to be removed at the film cutting station to the product protective film separation station, and at the same time transports the products to be removed at the loading station to the film cutting station. After the product to be defilmed is transported to the corresponding station, the product transport mechanism transfers the product to be defilmed at the product protective film separation station to between the product limit block and the product pressing block, and the product pressing cylinder drives the product pressing block to move forward until the product to be defilmed is suspended and fixed between the product limit block and the product pressing block, and the high-pressure air connector sprays high-pressure air to the suspended and fixed product to be defilmed, so that the protective film is separated from the product, and the high-pressure air connector located on the rear side of the suspended and fixed product to be defilmed sprays high-pressure air, so that the detached protective film is transferred to the protective film collection box, and at the same time, the product pressing cylinder drives the product pressing block to move backward, so that the defilmed product is separated from the fixed force and falls on the product protective film separation station, and the product pushing cylinder extends forward to push the defilmed product on the product protective film separation station into the product collection box. Such a defilming device can efficiently and automatically peel off the protective film for coated products, so as to realize the recycling and reuse of the products.

[0182] During the film removal process, no manual intervention is required. The product and the protective film fall from two different channels and are separated and collected in containers. Compared with the existing manual cutting and peeling method, it can greatly reduce safety hazards and labor costs and improve recycling efficiency. This application can be compatible with processing products of different shapes at the same time, and has high compatibility, especially for irregular products such as curved products. Laser cutting cannot achieve autofocus, resulting in poor cutting effect. The laser cutting method cannot cut products with similar melting points. This application is not affected by the melting points of the product and the protective film. It is still applicable to situations where the melting points of the product and the protective film are close, such as the coated antenna pole cover on the router, which can efficiently peel off the protective film. The protective film of some coated products has a certain viscosity, or because of static electricity, the protective film and the product are adhered together, which is difficult to peel off. The existing laser cutting and separation methods after crushing cannot solve this problem. The present application uses a serrated blade to cut the product to be removed, and can tear the protective film on the product along the blade. Then the high-pressure air needle blows out high-pressure air to completely peel off the protective film from the product, thereby separating the product from the protective film. Compared with the laser cutting mode, the present application can reduce pollution to the environment, and the equipment cost and processing cost are lower than laser cutting, the later maintenance is simple, and the economic feasibility is higher.
