[0001] The present disclosure relates to the field of diaphragm lamination technology, and in particular to a high-precision force-controlled flexible lamination device. Background Art

[0002] Currently, many products require protective film during automated production. As products become more diverse, the areas where the film needs to be applied are becoming more irregular and uneven. Conventional film laminating devices can only apply film to flat surfaces, but are unable to apply film to irregular, uneven surfaces.

[0003] Summary of the Invention

[0004] In order to solve at least one of the technical problems mentioned above, the present disclosure proposes a high-precision force-controlled flexible bonding device.

[0005] According to some embodiments of the present disclosure, a high-precision force-controlled flexible bonding device is provided, comprising a fixed seat and a transmission structure arranged above the fixed seat, the transmission structure comprising a first visual positioning component and a bonding claw, the first visual positioning component is used for positioning and guiding the bonding claw when bonding the film; the bonding claw is installed at the bottom of the transmission structure, the bonding claw comprises a film suction component and a film pressing component, the film pressing component comprises at least two pressing blocks, the bottom structure of the at least two pressing blocks matches the structure of the film surface of the part to be bonded; the fixed seat comprises a second visual positioning component, a film temporary storage position and a film bonding platform, the second visual positioning component is used for positioning and guiding the film suction component when sucking the film; the film temporary storage position and the film bonding platform are installed on the top of the fixed seat, the film temporary storage position stores the film, and the film bonding platform places the part to be bonded.

[0006] Based on the above solution, the uneven surface is divided into multiple film-sticking areas, and a corresponding number of pressing blocks are set. By splitting the pressing blocks, precise film sticking on the uneven surface can be achieved, effectively preventing deformation of the film and loose fitting when sticking on the uneven surface.

[0007] In some possible embodiments, the at least two pressing blocks include a first pressing block, a second pressing block or a third pressing block, the bottom structure of the first pressing block is a planar structure, which matches the planar structure of the film-pasting surface of the component to be film-pasted; the bottom structure of the second pressing block is a stepped structure, which matches the stepped structure of the film-pasting surface of the component to be film-pasted; the bottom structure of the third pressing block is a convex structure, which matches the groove structure of the film-pasting surface of the component to be film-pasted.

[0008] Based on the above solution, the film lamination operation can be performed on products with stepped surfaces or grooved surfaces.

[0009] In some possible implementations, each of the pressing blocks is connected to a transmission member, and the transmission member is used to control the vertical movement of the pressing block, so that each of the pressing blocks can independently complete the film pressing action.

[0010] Based on the above solution, each pressing block has an independent transmission part, which can apply film to different structural parts of the film-applying component in sequence, avoiding interference in the film-applying movement between the pressing blocks and making the film fit more tightly.

[0011] In some possible implementations, the transmission structure includes a pressure controller, which is used to adjust the pressure when the laminating claws laminate the diaphragm, and the pressure controller is transmission-connected to the laminating claws.

[0012] Based on the above solution, the pressure of the laminating diaphragm is precisely adjusted by a pressure controller, and the force of the laminating diaphragm is controlled to prevent damage to the diaphragm.

[0013] In some possible embodiments, the transmission structure includes a first air pump, the pressure controller is a precision pressure regulating valve, the first air pump is pneumatically connected to the bonding claw through the precision pressure regulating valve, and the precision pressure regulating valve is used to adjust the air pressure of the output gas of the first air pump to the bonding claw.

[0014] Based on the above solution, the accuracy of pressure control of the laminating diaphragm is further improved, the diaphragm is protected, the diaphragm is prevented from being damaged, and the yield rate of diaphragm lamination is improved.

[0015] In some possible implementations, a pressure sensor is provided on the laminating claw, the pressure sensor is communicatively connected to the controller of the transmission structure, and the pressure sensor is used to detect the pressure when the laminating claw laminates the diaphragm.

[0016] Based on the above solution, the film lamination pressure is fed back in real time through the pressure sensor, and the film lamination pressure is adjusted in real time through the pressure controller to achieve the effect of flexible control of diaphragm lamination, thereby protecting the diaphragm, preventing diaphragm damage, and improving the yield rate of diaphragm lamination.

[0017] In some possible implementations, the film suction assembly includes a suction cup and a second air pump, the second air pump is connected to the suction cup via an air pipe, and the suction cup is arranged at the bottom of the pressing block.

[0018] Based on the above solution, the film suction function and the film pressing function are structurally integrated to reduce the waste of workstations, achieve the effect of integration of suction and pressing tooling, and effectively save the space of the device.

[0019] In some possible implementations, the suction cup is integrally provided with the pressing block, the pressing block is provided with a vacuum air hole, the top end of the vacuum air hole is connected to the air pipe, and the bottom end of the vacuum air hole adsorbs the membrane.

[0020] Based on the above solution, the pressing block has a suction cup function, and the diaphragm can be taken and placed without additional suction cup components on the pressing block. By integrating the pressing block and the suction cup, the structure of the fitting claw is simplified and the overall number of parts of the device is reduced.

[0021] In some possible implementations, a protective layer is provided on the surface of the suction cup, and the protective layer is made of a soft material. The protective layer is used to protect the film when the laminating claws suck and laminar the film.

[0022] Based on the above solution, the suction cup made of a softer material will not scratch the film when sucking it, nor will it crush the film when applying the film, thereby avoiding poor film application effect caused by damage to the film.

[0023] In some possible implementations, the first visual positioning component and the second visual positioning component are CCD visual devices, and both the first visual positioning component and the second visual positioning component are communicatively connected to a controller of the transmission structure.

[0024] Based on the above solution, the CCD vision device can convert the optical image into a digital signal. The controller of the transmission structure directly receives the digital signal of the CCD vision device, thereby controlling the movement of the bonding claws to achieve high-precision positioning, thereby achieving the effect of high-precision film bonding.

[0025] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

Those skilled in the art will appreciate that the present disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main points of the present disclosure.

[0046] To facilitate understanding of the present disclosure, some technical terms appearing in the present disclosure are explained below:

[0047] CCD (Charge Coupled Device), also known as a CCD image sensor, is a semiconductor device that converts optical images into digital signals. Tiny photosensitive materials embedded in a CCD are called pixels. The more pixels a CCD has, the higher the image resolution it provides. A CCD functions like film, converting image pixels into digital signals.

[0048] CCD visual equipment: a visual device that includes CCD devices, such as color CCD cameras, black and white CCD cameras, CCD microscopes, etc.

[0049] Currently, in the automated production of electronic equipment, microelectronic products and spare parts, products require surface film protection. In related technologies, surface film laminating equipment is usually equipped with a film suction station and a film laminating station. The suction film is first placed on the surface of the product to be laminarized, and then the film is pressed down by a laminating workpiece to make it adhere to the product.

[0050] With the increase in product types and changes in the product's own structure, the shapes of more and more products that need to be filmed have begun to become irregular, and the surface to be filmed is no longer a flat surface. The relevant technology still uses the method of first sucking the film and placing the film sheet and then pressing the film to apply the film, resulting in the film sheet being unable to fit the surface of the product. In some cases, the film sheet will be damaged during the film application process due to the uneven surface structure of the product.

[0051] In order to solve the above-mentioned technical problems, the embodiments of the present disclosure provide a high-precision force-controlled flexible bonding device, which divides the uneven surface of the product to be bonded into structures such as planes, steps, grooves, and curved surfaces through the split setting of the pressing blocks, and sets independent pressing blocks that cooperate with the above-mentioned structures. After the pressing blocks are assembled, they can just cooperate with the structure of the uneven surface of the product, so that the diaphragm can be tightly attached to the uneven surface of the product.

[0052] In the embodiment of the present disclosure, please refer to Figure 1. The above-mentioned device includes a fixed seat 1 and a transmission structure 2 arranged above the fixed seat 1. The transmission structure 2 includes a first visual positioning component 3 and a fitting claw 4. The first visual positioning component 3 is used for positioning and guiding the fitting claw 4 when fitting the film; the fitting claw 4 is installed at the bottom of the transmission structure 2. The fitting claw 4 includes a film suction component and a film pressing component. The film pressing component includes at least two pressing blocks. The bottom structure of at least two pressing blocks matches the structure of the film surface of the part to be filmed; the fixed seat 1 includes a second visual positioning component 5, a film temporary storage position 6 and a film pasting platform 7. The second visual positioning component 5 is used for positioning and guiding the film suction component when sucking the film; the film temporary storage position 6 and the film pasting platform 7 are installed on the top of the fixed seat 1. The film temporary storage position 6 stores the film, and the film pasting platform 7 places the part to be filmed.

[0053] Based on the above embodiment, the transmission structure 2 carries the fitting claw 4 to move above the film temporary storage position 6, and the second visual positioning component 5 performs real-time positioning and guidance, so that the film suction component is aligned with the film temporary storage position 6, and then the film suction component absorbs the film, and the transmission structure 2 carries the fitting claw 4 to move above the film laminating platform 7, and the first visual positioning component 3 performs real-time positioning and guidance, so that the film suction component is aligned with the part to be laminating on the film laminating platform 7, and the film suction component places the film on the part to be laminating, and then the first visual positioning component 3 continues to position and guide, so that the film pressing component is aligned with the film and the part to be laminating, and finally the film pressing component presses down the film so that the film is attached to the part to be laminating.

[0054] In the above embodiment, the first visual positioning component 3 and the second visual positioning component 5 are both devices or equipment that realize the positioning and guiding function based on visual devices. Please refer to Figure 1. Since the fixing seat 1 and the transmission structure 2 are separated in mechanical structure and there is no connection relationship between them, in order to ensure that the bonding claws 4 on the transmission structure 2 accurately absorb and press the film, the above-mentioned first visual positioning component 3 and the second visual positioning component 5 are set. Among them, the first visual positioning component 3 serves as a positioning and guiding structure when bonding the film. It detects the position of the part to be bonded and sends the position information to the transmission structure 2. The transmission structure 2 moves so that the bonding claws 4 are aligned with the part to be bonded; and the second visual positioning component 5 serves as a positioning and guiding structure when sucking the film. It detects the storage position of the film, that is, the position of the temporary storage position 6 of the film, and sends the position information to the transmission structure 2. The transmission structure 2 moves so that the bonding claws 4 are aligned with the film.

[0055] It should be understood that in the above-mentioned devices or equipment that realize the positioning and guidance function based on visual devices, the visual devices can be optical imaging devices such as cameras or cameras, or they can be infrared transmitters and receivers, laser radars and other devices.

[0056] In the embodiment of the present disclosure, the first visual positioning component 3 and the second visual positioning component 5 are divided according to their corresponding functions rather than specifying the structure and quantity. That is to say, in an actual implementation, the first visual positioning component 3 and the second visual positioning component 5 may be installed in the same visual device; or the first visual positioning component 3 or the second visual positioning component 5 may be composed of multiple visual devices respectively.

[0057] In some embodiments of the present disclosure, the first visual positioning component 3 and the second visual positioning component 5 are CCD vision devices, and both the first visual positioning component 3 and the second visual positioning component 5 are in communication with the controller of the transmission structure 2. Based on the above embodiment, since the CCD vision device contains a CCD device, the CCD device can convert image data into a digital signal and send it directly to the controller of the transmission structure 2, thereby reducing the hardware and software requirements for image processing, that is, it can reduce unnecessary encoders, decoders, etc.

[0058] In some possible implementations, the first visual positioning component 3 and the second visual positioning component 5 provide feedback to each other. When the second visual positioning component 5 is guiding the positioning of the film, the first visual positioning component 3 can take a photo to confirm whether the pressing block of the laminating claw 4 is aligned with the film when the laminating claw 4 absorbs the film, and whether the film is offset relative to the pressing block during the movement of the laminating claw 4 after absorbing the film. Similarly, when the first visual positioning component 3 is guiding the positioning of the laminating film, the second visual positioning component 5 can take a photo to confirm whether the film is aligned with the part to be laminated. Based on the above implementation, the laminating accuracy can be further improved, the laminating error can be reduced, and the yield rate can be improved.

[0059] In some possible implementations, after completing the positioning guidance operation, the first visual positioning component 3 and / or the second visual positioning component 5 can also monitor the film application process, for example, by detecting whether there is any abnormality in the operation of the laminating claw 4 through photo comparison, checking whether the product after laminating is qualified through photo comparison, and checking whether there is any structural damage in the film suction component and the film pressing component of the laminating claw 4 through photo comparison. It should be understood that the present disclosure does not limit the functions of the first visual positioning component 3 and the second visual positioning component 5. In addition to the above-mentioned embodiments and implementation methods, the first visual positioning component 3 and the second visual positioning component 5 also have some functions based on the visual device itself in addition to guiding positioning. It can be understood that the first visual positioning component 3 and / or the second visual positioning component 5 of the present disclosure can include a connected data processing device, such as a single-chip microcomputer, an industrial computer, a programmable device, a router, and a server connected to the router for communication.

[0060] In some embodiments of the present disclosure, the pressing blocks are arranged in accordance with the structure of the uneven surface of the component to be film-applied. Figure 2 shows the structure of the component to be film-applied according to an embodiment of the present disclosure. The uneven surface at the top of the component can be divided into a flat surface on the left, a stepped surface on the right, and a groove portion formed on the stepped surface. Corresponding to the above-described structure, the pressing blocks can be provided with a first pressing block 41, a second pressing block 42, and a third pressing block 43. The bottom structure of the first pressing block 41 is a flat structure that matches the flat surface structure of the film-applied surface of the component to be film-applied. The bottom structure of the second pressing block 42 is a stepped structure that matches the stepped structure of the film-applied surface of the component to be film-applied. The bottom structure of the third pressing block 43 is a protrusion structure that matches the groove structure of the film-applied surface of the component to be film-applied. In this embodiment, the requirement for film-applied with a groove-type structure is that the contact area between the diaphragm and the groove must be at least half the area of ​​the groove; otherwise, the fit will not be tight and the diaphragm will easily fall off. To achieve this requirement, the protrusion structure and the groove-type structure should have a clearance fit, and the clearance size is related to the thickness of the diaphragm.

[0061] In the above embodiment, there is no limit on the number of the first pressing blocks 41, the second pressing blocks 42, and the third pressing blocks 43. The number of the first pressing blocks 41, the second pressing blocks 42, and the third pressing blocks 43 is determined based on the structure of the component to be film-coated. For example, when the component to be film-coated has multiple grooves, and all of the grooves need to be protected by film, the number of third pressing blocks 43 is the corresponding number. When the component to be film-coated has a multi-step structure, the number of second pressing blocks 42 corresponds to the number of steps.

[0062] In the above embodiment, the laminating claw 4 is not limited to being equipped with the first pressure block 41, the second pressure block 42 and the third pressure block 43 at the same time. That is to say, in addition to being equipped with all of them, the laminating claw 4 can be equipped with only one of the first pressure block 41, the second pressure block 42 and the third pressure block 43, or it can be equipped with any two of them. For example, when the part to be filmed is a stepped surface, the laminating claw 4 is equipped with the first pressure block 41 and the second pressure block 42; when the part to be filmed is a flat device with a groove, the laminating claw 4 is equipped with the first pressure block 41 and the third pressure block 43; when the part to be filmed is a stepped structure with a groove, the laminating claw 4 can be equipped with the second pressure block 42 and the third pressure block 43, or it can be equipped with the first pressure block 41, the second pressure block 42 and the third pressure block 43 at the same time.

[0063] In the above embodiment, the specific structural design of the pressing block is not limited. The first pressing block 41, the second pressing block 42, and the third pressing block 43 are designed based on the structural division of the uneven surface of the component to be filmed. It is understood that the structural division of the uneven surface of the component to be filmed is not limited to one method. For example, the uneven surface of the component to be filmed can be divided into two flat surfaces, a middle inclined surface, and a groove on the right flat surface; or the uneven surface can be divided into a left flat surface, a middle inclined surface, and a right grooved structure.

[0064] In addition, the specific structure of the pressing block depends on the structure of the part to be filmed. The above embodiment only illustrates a part to be filmed. It should be understood that in the actual production process, the part to be filmed can be of various shapes and structures, and the structure of the pressing block is also designed accordingly. For example, in some possible embodiments, the uneven surface of the part to be filmed includes a curved surface structure, and the bottom structure of the corresponding pressing block can be designed as a curved surface structure; in some possible embodiments, the uneven surface of the part to be filmed includes a convex structure, and the bottom structure of the corresponding pressing block can be designed as a groove structure that matches the convex structure; in some possible embodiments, the uneven surface of the part to be filmed includes a continuous curved surface structure, and the bottom structure of the corresponding pressing block can be designed as a continuous curved surface structure that matches it.

[0065] In the above embodiment, the assembly method between the pressing blocks is not limited, that is, different pressing blocks can be assembled together by fitting together, or they can be installed separately by means of transmission parts. For example, in some possible implementations, please refer to Figure 3, different pressing blocks can be assembled together in a horizontal parallel arrangement; in some possible implementations, different pressing blocks can be assembled in a nested manner, please refer to Figure 4, the second pressing block 42 is mounted on the third pressing block 43; in some possible implementations, multiple pressing blocks with different structures are installed on a pressing block switching device, and the fitting claw 4 switches to select a pressing block each time, and after the film pressing operation is completed, another pressing block is switched.

[0066] In some embodiments of the present disclosure, each pressing block is connected to a transmission element that controls its vertical movement, allowing each pressing block to independently perform film lamination. Based on this approach, each pressing block has an independent transmission element, allowing film to be applied sequentially to different structural components of the component to be filmed, avoiding interference between the pressing blocks during film application and ensuring a tighter film lamination.

[0067] In a specific embodiment, referring to the parts to be film-coated as shown in FIG2 and FIG5 , in order to perform the film-coating operation on the parts shown in the figure, the laminating claw 4 is provided with a first pressing block 41, a second pressing block 42, and a third pressing block 43. The bottom structure of the first pressing block 41 is a flat structure, which matches the flat structure of the film-coating surface of the part to be film-coated. The bottom structure of the second pressing block 42 is a stepped structure, which matches the stepped structure of the film-coating surface of the part to be film-coated. The bottom structure of the third pressing block 43 is a convex structure, which matches the groove structure of the film-coating surface of the part to be film-coated. The first pressing block 41 and the second pressing block 42 are arranged and assembled in parallel, and the second pressing block 42 and the third pressing block 43 are nested and assembled, with the second pressing block 42 being arranged outside the third pressing block 43. The tops of the first pressing block 41, the second pressing block 42, and the third pressing block 43 are respectively connected to cylinder assemblies. The three cylinder assemblies operate independently of each other to control the downward and upward movement of the first pressing block 41, the second pressing block 42, and the third pressing block 43, respectively.

[0068] Based on the above embodiments, the film laminating process of a high-precision force-controlled flexible laminating device disclosed herein includes:

[0069] 1. After the laminating claw 4 absorbs the film, the transmission structure 2 carries the laminating claw 4 to move the film. The laminating claw 4 is aligned with the second visual positioning component 5. The second visual positioning component 5 takes a photo to confirm the position of the film on the laminating claw 4;

[0070] 2. The first visual positioning component 3 moves to the top of the component to be film-coated, takes a picture to obtain the position of the component to be film-coated, and feeds back to the transmission structure 2;

[0071] 3. The transmission structure 2 carries the laminating claw 4 to move above the component to be laminating. The first pressing block 41, the second pressing block 42 and the third pressing block 43 are all in the initial position. The laminating claw 4 drives the first pressing block 41, the second pressing block 42 and the third pressing block 43 to press down as a whole until the film is completely in contact with the boss on the left side of the component to be laminating. That is, the first pressing block 41 laminates the film on the flat surface structure on the left side of the component to be laminating. At this time, the second pressing block 42 and the third pressing block 43 do not contact the component to be laminating.

[0072] 4. The third pressing block 43 extends downward to fit the film sheet with the groove on the right side of the component to be film-coated. That is, the third pressing block 43 performs film-coating on the groove structure on the right side of the component to be film-coated. After the lamination is successful, the third pressing block 43 is retracted upward.

[0073] 5. The second pressing block 42 extends downward to completely adhere the film to the middle inclined surface and right plane of the component to be laminated. That is, the second pressing block 42 laminates the film to the stepped structure of the component to be laminated. After the lamination is successful, the second pressing block 42 is retracted upward. At this time, the first pressing block 41, the second pressing block 42 and the third pressing block 43 return to their initial positions again.

[0074] 6. The laminating claws 4 are retracted upward as a whole under the drive of the transmission structure 2, and the laminating work on the component is completed.

[0075] In some embodiments of the present disclosure, the transmission structure 2 includes a pressure controller, which is used to adjust the pressure when the bonding claw 4 bonds to the diaphragm, and the pressure controller is in transmission connection with the bonding claw 4. Based on the above scheme, the pressure of the bonding diaphragm is accurately adjusted by the pressure controller to ensure that the pressure is higher than the minimum value, that is, the minimum pressure at which the diaphragm can be tightly bonded to the surface of the component to be bonded, and also ensure that the pressure is less than the maximum value, that is, the maximum pressure at which the diaphragm can maintain its shape without deformation or damage. The pressure controller is used to precisely control the pressure of the diaphragm bonding process, thereby enhancing the tightness of the diaphragm bonding and preventing the diaphragm from being damaged during the bonding process.

[0076] In the above embodiment, the specific implementation form of the pressure controller is not limited. It should be understood that the pressure controller is selected based on the adaptability of the transmission structure 2 to the transmission assembly of the bonding gripper 4. In other words, when the transmission structure 2 controls the movement of the bonding gripper 4 via the motor transmission assembly, the pressure controller is configured as an encoder or other electronic control device capable of running a pressure control program; when the transmission structure 2 controls the movement of the bonding gripper 4 via the cylinder transmission assembly, the pressure controller is configured as a valve control component; when the transmission structure 2 controls the movement of the bonding gripper 4 via the hydraulic transmission assembly, the pressure controller is configured as a valve body, an electronic controller, or a combination of the two.

[0077] In one specific embodiment, referring to FIG6 , the transmission structure 2 includes a first air pump, and the pressure controller is a precision pressure regulating valve 21. The first air pump is pneumatically connected to the laminating jaw 4 via the precision pressure regulating valve 21. The precision pressure regulating valve 21 is used to regulate the pressure of the gas output by the first air pump to the laminating jaw 4. Based on the above embodiment, the use of a pneumatic drive method is easy to adjust and control, has a fast response, and can improve the precision of motion control. For film laminating processes such as electronic devices, the corresponding driving force requires low power density and low motion speed, making the pneumatic drive method more suitable as the driving method for the transmission structure 2. In the case of pneumatic drive control, the laminating pressure is equal to the product of the air pressure value and the pressure area. To further improve the control accuracy of the laminating pressure of the laminating jaw 4 and the pressure block, it is necessary to precisely control the output air pressure of the first air pump. Therefore, the precision pressure regulating valve 21 is provided to achieve precise control of the laminating pressure of the laminating jaw 4 and the pressure block, thereby enhancing the tightness of the film lamination and preventing damage to the film during the lamination process.

[0078] In some embodiments of the present disclosure, referring to FIG7 , the laminating claw 4 is further provided with a pressure sensor 44 , which is in communication with the controller of the transmission structure 2 and is used to detect the pressure applied by the laminating claw 4 to the diaphragm. Based on the above embodiment, the device provides real-time feedback on the laminating pressure via the pressure sensor 44 , and the transmission structure 2 subsequently adjusts the laminating pressure in real time via the pressure controller. This control process of the laminating pressure utilizes negative feedback, achieving the effect of flexible control of diaphragm lamination, thereby protecting the diaphragm, preventing damage to the diaphragm, and improving the yield rate of diaphragm lamination.

[0079] In the above embodiment, the specific type and structure of the pressure sensor 44 are not limited. That is to say, the pressure sensor 44 can be a piezoelectric device, a pressure-sensitive device, or a detection circuit / device / apparatus implemented based on the pressure sensor 44. The pressure sensor 44 can also be a device or apparatus that measures other parameters and converts the measured data into film-sticking pressure parameters, such as a visual component that calculates the film-sticking pressure by detecting the change in the thickness of the diaphragm.

[0080] In the above embodiment, the specific method of the pressure sensor 44 for measuring the film laminating pressure is not limited. That is, the pressure sensor 44 can be directly installed on the laminating claw 4 or the pressure block, or the pressure sensor 44 can be installed on the connecting part between the transmission structure 2 and the laminating claw 4, or a visual component can be installed on the transmission structure 2 to detect the change in the thickness of the diaphragm and calculate the film laminating pressure.

[0081] In some embodiments of the present disclosure, the film suction assembly includes a suction cup 45 and a second air pump, the second air pump being connected to the suction cup 45 via an air tube, and the suction cup 45 being disposed at the bottom of the pressing block. Based on the above embodiments, the following problems can be solved: the two workstations for film suction and film application in the laminating device occupy a large amount of space, and the connection between the film suction and film application processes is not smooth. During the entire laminating process, after the film suction assembly has sucked and placed the film, additional movement operations are required to avoid interference with the film application assembly. This process involves too many redundant steps, which increases the time required for the laminating operation, reduces the efficiency of the laminating operation, and also makes the overall structure of the laminating device more complex.

[0082] In the above embodiment, by placing the suction cup 45 at the bottom of the pressure block, the laminating claw 4 achieves integrated suction and pressure in terms of structural design and functional operation. This integrated suction and pressure design eliminates the need for the suction cup 45 to remove the film after it has been applied to and placed on the film. The pressure block can simply press downward to complete the laminating operation, thus avoiding the reduced laminating efficiency caused by the aforementioned removal of the suction cup 45. This reduces the space occupied by the device and improves laminating efficiency.

[0083] In the above embodiment, the suction cup 45 provided at the bottom of the pressing block does not affect the step of pressing the pressing block to form a film, that is, the existence of the suction cup 45 does not affect the operation step of laminating the pressing block to the film, and the structural design of the suction cup 45 does not interfere with the process of laminating the pressing block to the film. That is to say, in some possible embodiments, the suction cup 45 can be a sheet suction cup 45 or a block suction cup 45 with a relatively low thickness, which is directly attached to the bottom of the pressing block. The suction cup 45 is consistent with the special structure of the bottom of the pressing block and is installed in a stacked form; in some possible embodiments, the suction cup 45 can be individually designed according to the uneven surface structure of the component to be filmed. In this case, the suction cup 45 serves as a component of the pressing block to assist in achieving special structure filming; in some possible embodiments, the suction cup 45 can also be installed only on a pressing block with a flat pressing surface. During the process of sucking and placing the film, only part of the position of the film is adsorbed, rather than the entire area; in some possible embodiments, the suction cup 45 is arranged at the bottom of both sides of the pressing block. When sucking the film, the suction cup 45 adsorbs the edge of the film, and after aligning it with the component to be filmed, the pressing block presses down on the main part of the film. This embodiment can avoid the problem of loose fitting caused by the expansion and deformation of the film when processing groove-type surface filming.

[0084] In some possible embodiments, the pressing blocks adopt a uniform shape and structure, such as a rectangular column, and the suction cups 45 are designed to correspond to the structure of the component to be film-coated. The suction cups 45 are detachably mounted on the bottom of the pressing blocks. Based on this solution, when the laminating device is laminating different products, there is no need to disassemble and replace the individual pressing blocks of the laminating assembly. Simply remove the suction cups 45 from the pressing block and replace them with the suction cups 45 for the corresponding product. This allows for quick adjustment of the device, shortening the time it takes to switch between production line operations and improving work efficiency.

[0085] In a specific implementation of the above embodiment, the structure of the part to be film-attached is shown in Figures 2 and 5. At this time, the suction cup 45 of the bonding claw 4 is shown in Figure 8. The bonding claw 4 includes two suction cups 45. The suction cup 45 on the left corresponds to the plane structure on the left side of the part to be film-attached, and the suction cup 45 on the right corresponds to the stepped structure on the right side of the part to be film-attached. The suction cup 45 on the right includes a slope block and a plane block. Suction holes are provided on the plane block, and no suction holes are provided on the slope block. When the suction cup 45 under this design absorbs the membrane, the area ratio of the suction hole to the membrane is large, which can ensure firm absorption. While absorbing the membrane, the suction cup 45 can also shape the membrane in advance, which helps to make the membrane fit tightly with the part to be film-attached during subsequent film pressing.

[0086] In a specific embodiment, the suction cup 45 is integrated with the pressing block, and the pressing block is provided with a vacuum air hole 451. The top of the vacuum air hole 451 is connected to the above-mentioned second air pump through an air pipe, and the bottom of the vacuum air hole 451 is used to adsorb the diaphragm. Based on the above embodiment, the pressing block has the function of the suction cup 45, that is, the pressing block serves as the suction cup 45 of the film-absorbing component. There is no need to additionally install the suction cup 45 on the pressing block to achieve the absorption and placement of the diaphragm. In actual use, after the pressing block absorbs the diaphragm, there is no need to place the diaphragm first and then press it down to fit it. Instead, it is directly moved down and pressed until the diaphragm is tightly fitted, and then the pressing block is retracted. Through the above-mentioned scheme of the integrated arrangement of the pressing block and the suction cup 45, the structure of the bonding claw 4 can be simplified, the film-absorbing component and the film-pressing component can be integrated, and the components can be multifunctional, thereby reducing the components of the bonding claw 4 and further reducing the number of overall parts of the entire bonding device.

[0087] In the embodiments of the present disclosure, the specific definition of the suction cup 45 and the pressure block after being set as one body is not limited, that is, a component that has both the functions of the suction cup 45 and the pressure block can be defined as a pressure block with the function of the suction cup 45, or as a suction cup 45 with a film pressing function, or as an integrated suction and pressure device / equipment / component / part / structure. It should be understood that the present disclosure only provides several possible design schemes for the specific structure of the integrated suction and pressure. In the actual production process, the configuration options of the suction cup 45 and the pressure block can be flexibly adjusted and replaced. For example, in some possible embodiments, the suction cup 45 can be a magnetic component, and the corresponding pressure block can be a die component.

[0088] In some embodiments of the present disclosure, the suction cup 45 of the film suction assembly is used to suck the film by pumping air. When sucking the film, in order to ensure that the suction cup 45 can firmly suck the film, the suction force of the vacuum pores 451 or the suction holes on the suction cup 45 needs to be greater than the minimum suction force value, which often results in traces of suction holes being left on the film. In addition, in some embodiments, the suction cup 45 is fixedly installed at the bottom of the pressing block. During the downward pressing process of the pressing block, in order to ensure that the film is tightly attached to the part to be filmed and does not fall off, the film-attaching pressure must also be greater than the minimum pressure value. The pressure that satisfies the tight fit often also causes the vacuum pores 451 or the suction holes of the suction cup 45 to leave marks on the surface of the film, and even cause damage or scratches to the film. In order to solve the above problems, the present disclosure provides a protective layer on the surface of the suction cup 45. The protective layer is made of soft material and is used to protect the film when the bonding claw 4 absorbs the film and attaches the film. Based on the above solution, the softer suction cup 45 will not scratch the film when sucking it, nor will it crush the film when applying the film, thus avoiding poor film application due to film damage or scratches. The solution of providing a protective layer on the suction cup 45 can be combined with the force control solution in other embodiments of the present disclosure to achieve the effect of flexible film application.

[0089] In the above embodiment, the protective layer can be additionally provided on the basis of the components, for example, the suction cup 45 and / or the pressing block are coated with rubber, so that the surface of the suction cup 45 and the pressing block is wrapped with a layer of soft rubber. In some embodiments, the protective layer can also be a structural property of the suction cup 45 itself, that is, the suction cup 45 itself is made of materials of different hardness, wherein the material of the part in contact with the diaphragm is softer, and the material of the remaining parts is harder. In one possible embodiment, the suction cup 45 is made of plastic material, wherein the part of the suction cup 45 in contact with the diaphragm, i.e., the bottom of the suction cup 45, is made of soft plastic; and the other parts of the suction cup 45 are made of hard plastic with higher strength.

Numerous modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or technological improvements in the marketplace, or to enable others skilled in the art to understand the embodiments disclosed herein.
