Description

Technical Field

[0001] This invention relates to the field of automated membrane material conveying equipment, and more specifically to a membrane supply device. Background Technology

[0002] During continuous film supply, the previous roll and the next roll need to be thermally bonded to ensure a continuous and uninterrupted supply of film material. When the previous roll of film is detected to have reached its end, the film material needs to be cut so that the splicing head can thermally bond the end of the previous roll of film to the beginning of the next roll of film.

[0003] While existing technologies include automated equipment capable of thermally bonding membranes, these typically have only two film roll installation stations, allowing for the continuous transport of only two rolls at a time. After two rolls are used, frequent reloading is required, thus failing to effectively improve membrane transport efficiency. Furthermore, the splicing heads in existing splicing equipment are generally fixed in position for thermal bonding, limiting the working range of the splicing head. The machine must stop after the previous roll is delivered, and the next roll must be manually or automatically loaded to the splicing head's position, thus failing to increase the quantity of film loaded per batch or improve membrane transport efficiency.

[0004] In conclusion, there is an urgent need for a membrane supply device to solve the problems existing in the current technology. Summary of the Invention

[0005] The purpose of this invention is to provide a film feeding device that addresses the problem of frequent feeding and the inability to effectively increase the number of film rolls fed in a single operation in existing film feeding devices. The specific technical solution is as follows: A film supply device, comprising: The material trolley includes n unwinding assemblies and n working station assemblies. The unwinding assemblies are used to place the roll film, and the working station assemblies are used to place the first section of film material released from the roll film, where n is a natural number greater than or equal to 1. A film bonding device includes a frame assembly and a working module mounted on the frame assembly via a Y-axis sliding module; the working module (304) includes a mounting frame, a film bonding assembly, and a Z-axis drive component, the film bonding assembly being slidably mounted on the mounting frame along the Z-axis and driven by the Z-axis drive component; the film bonding assembly includes a film bonding frame, a cutter, a heat bonding module, and a pressing head, all mounted on the film bonding frame, the cutter being mounted on the film bonding frame via a cutter drive component and located between the heat bonding module and the pressing head, the heat bonding module including a heating element and multiple air holes; The positioning track is used to transport the material trolley to the bottom of the film splicing equipment.

[0006] In a preferred embodiment of the above technical solution, the workstation assembly includes a workstation panel and a film pressing rod. The workstation panel is provided with a lower cutting groove and a film pressing groove in parallel. The film pressing rod is movably disposed in the film pressing groove. After the film roll releases the film material, the first section of the film material is placed on the workstation panel, and the end of the first section of the film material is placed in the film pressing groove. The film pressing rod applies pressure to the film material below it. When the external force on the film material is greater than the pressure applied by the film pressing rod, the film material will be pulled out from below the film pressing rod.

[0007] In a preferred embodiment of the above technical solution, the workstation assembly further includes k conveying rollers, and the film material released from the roll passes around the k conveying rollers in sequence and is placed on the upper surface of the workstation panel; where k is a natural number greater than or equal to 1, and the highest point on the roller surface circle of the last conveying roller is flush with the upper surface of the workstation panel.

[0008] In a preferred embodiment of the above technical solutions, the film bonding assembly further includes at least two conveying rollers located on the side of the heat bonding module away from the film pressing head, and the film material is output from the film bonding assembly after passing through each conveying roller in sequence; wherein the last conveying roller is provided with a pressure block driven by a pressing drive, and when the pressure block presses against the roller surface of the last conveying roller, the film material on the roller surface is in a pressed state.

[0009] In the preferred embodiment of the above technical solution, the air hole is used for vacuuming or conveying cooling gas; when the air hole is used for vacuuming, it enables the film material to be adsorbed onto the bottom surface of the heat bonding module; when the air hole is used for conveying cooling gas, it enables the bonding position of the film material to be cooled and dissipated.

[0010] In a preferred embodiment of the above technical solutions, the membrane bonding assembly further includes a correction sensor for detecting the position of the membrane material on the membrane bonding assembly, an edge detection sensor for detecting the edge of the membrane material, and a tail section detection sensor for detecting the tail section of the membrane material.

[0011] In a preferred embodiment of the above technical solutions, the positioning track includes: The ground rail base has two parallel X-axis guide rails that are used to guide the movement of the material trolley. The positioning and correction assembly includes a positioning slide plate, a shift fork, a swing fork, a telescopic power component II, and a sliding block. The positioning slide plate is slidably mounted on the ground rail base along the X-axis and is located between two X-axis guide rails. The sliding block is slidably mounted on the positioning slide plate along the X-axis and is driven by the telescopic power component II. The sliding block has shift forks at both ends in the Y-axis direction. The positioning slide plate has a swing fork corresponding to the shift forks and elastically rotating around the Y-axis. The middle part of the shift fork is rotatably mounted on the positioning slide plate around the Z-axis. One end of the shift fork is movably connected to the sliding block, and its other end cooperates with its corresponding swing fork to clamp the material trolley. X-axis drive assembly, which is used to drive the positioning slide plate to slide on the ground rail base.

[0012] In the preferred embodiment of the above technical solution, the upper surface of the X-guide rail is provided with a wear-resistant strip, and the bottom of the material trolley is provided with a wear-resistant component. The wear-resistant strip is used to support and lift the wear-resistant component. The inner side of the lower end of each of the two legs of the frame assembly is equipped with a clamping component. The clamping component applies a clamping force to clamp the material trolley in the supported and lifted state onto the wear-resistant strip.

[0013] The preferred embodiment of the above technical solution further includes a buffer device disposed downstream of the film splicing equipment. The buffer device includes a buffer frame and a tension roller group one and a tension roller group two, both disposed on the buffer frame. The tension roller group one is located above the tension roller group two, and the tension roller group two is slidably disposed on the buffer frame. Both tension roller group one and tension roller group two include multiple tension rollers arranged in a row, and the film material is alternately wound between the tension rollers on tension roller group one and tension roller group two; The tension roller group two is based on The relationship with G slides along the cache frame; where The speed at which the membrane material enters the buffer device The speed at which membrane material is output from the buffer device The force generated by the speed difference between them, G is the weight of the tension roller group two.

[0014] In a preferred embodiment of the above technical solutions, the film splicing equipment further includes a correction system and a conveying assembly arranged sequentially downstream of the working module. The correction system is used to correct the film material output from the working module. The conveying assembly includes a film tension detection assembly and an output roller assembly. The film material output by the correction system passes sequentially through the film tension detection assembly and the output assembly before being output from the film splicing equipment.

[0015] The application of the technical solution of the present invention has the following beneficial effects: (1) Since the cutter is located between the pressing head and the heat bonding module, after the film bonding assembly presses down on the film material and the cutter cuts the film material, one side of the film material will be below the pressing head, and the other side of the film material will be below the heat bonding module. At this time, by drawing a vacuum through the air hole, the film material below the heat bonding module can be adsorbed onto the lower surface of the heat bonding module. The adsorbed film material can then follow the movement of the heat bonding module and be heat-bonded with the first section of the next roll of film. Through this film bonding equipment, each roll of film can be bonded together one by one, achieving the effect of continuously conveying several rolls of film material in one feeding. In this process, no manual intervention is required, which greatly reduces the labor intensity of workers and effectively improves the supply efficiency of film material. Since the working module can slide along the Y direction and the material trolley can slide along the X direction, the number of rolls of film fed at one time can be greatly increased, and the rolls of film on the material trolley can be smoothly bonded one by one for uninterrupted supply, reducing the frequency of feeding by workers.

[0016] (2) The air holes on the heat bonding module have the function of vacuum adsorption of film material or blowing cooling gas to the bonding position. After cutting the film, the film material can be adsorbed on the bottom surface of the heat bonding module to facilitate subsequent heat bonding of film material. It can also dissipate heat and cool the bonding position of the film material after heat bonding to achieve rapid recovery of film material supply.

[0017] (3) The work station panel of the working component is equipped with a lower cutting groove and a film pressing groove. The film pressing rod and the film pressing groove can press down the end of the film material to ensure that the film material is laid flat on the work station panel. With the cooperation of the heat sealing module and the film pressing head, the film material on both sides of the lower cutting groove can be pressed to ensure that the lower cutting rod can cut the film material smoothly. Since the pressure applied to the film material by the film pressing rod is not large, after the joining is completed, the end of the film material of the new roll of film can be automatically pulled out from under the film pressing rod, and the film supply can continue without manual intervention.

[0018] (4) The material trolley can be clamped by the cooperation of the shift fork and the swing fork. Then, the material trolley can move together with the positioning correction component by the action of the X-direction drive component, so that the material trolley can smoothly enter the positioning rail. After the material trolley enters the positioning rail, the material trolley can be driven by the X-direction drive component to switch different work stations on the material trolley to the working area and to fine-tune the position of the material on the work station, adapt to complex and ever-changing working conditions, and improve the success rate of the operation.

[0019] (5) The amount of film material buffered between tension roller group two and tension roller group one is dynamically changed by the up and down sliding of tension roller group two. When there is no film material continuously fed into the buffer device due to processes such as film loading and film splicing, the buffered film material can be used to continuously supply the film-using equipment, ensuring that the film-using equipment operates without stopping; when the buffer device resumes the input of film material, the speed at which the film material enters the buffer device is controlled. Greater than the speed at which the membrane material is output from the buffer device The tension roller assembly 2 utilizes its own weight to automatically drop the film material, thus re-buffering it. This process can be repeated to ensure a continuous supply of film material.

[0020] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

Detailed Implementation

[0022] To facilitate understanding of the present invention, a more complete description is provided below, along with preferred embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0024] Example: See Figure 1 This embodiment provides a film supply device that can feed, cut, and join films, automatically joining n rolls of film at a time without manual intervention. The film supply device includes a positioning rail 100, a material trolley 200, a film joining device 300, and a buffer device 400. The positioning rail 100 transports the material trolley to the underside of the film joining device 300, and simultaneously allows the material trolley to slide in the X-direction, enabling each section of film A01 on the material trolley to move to the working position of the film joining device for heat joining. The film joining device 300 has functions such as cutting, feeding, and joining films, and is the main equipment for continuous film supply. The buffer device is located between the outlet end of the film joining device and the inlet end of the film using device, acting as a buffer between film feeding and film use.

[0025] The following will provide a detailed description of the structural composition of the positioning track 100, material trolley 200, film bonding equipment 300, and buffer device 400 in this embodiment.

[0026] Figures 2-6 This is a schematic diagram of a positioning rail, which is used for clamping and transporting material trolleys, switching workstations, and correcting the position of materials at workstations to ensure that materials on the trolleys are accurately delivered to the designated work positions. The positioning rail includes: The ground rail base 111 has two parallel X-guide rails 102 for guiding the movement of the material trolley. The positioning and correction assembly 110 includes a positioning slide plate 1101, a shift fork 1102, a swing fork 1103, a telescopic power component 1106, and a sliding block 1108. The positioning slide plate 1101 is slidably mounted on the ground rail base 111 along the X-direction and is located between two X-direction guide rails 102. The sliding block 1108 is slidably mounted on the positioning slide plate 1101 along the X-direction and is driven by the telescopic power component 1106. The sliding block 1108 has shift forks 1102 at both ends in the Y-direction. The positioning slide plate 1101 has a swing fork 1103 corresponding to the shift forks 1102 and elastically rotating around the Y-direction. The middle part of the shift fork 1102 is rotatably mounted on the positioning slide plate 1101 around the Z-direction. One end of the shift fork 1102 is movably connected (i.e., slidably connected) to the sliding block 1108, and the other end cooperates with its corresponding swing fork 1103 to clamp the material trolley. The X-axis drive assembly is used to drive the positioning slide plate 1101 to slide on the ground rail base 111.

[0027] Please see Figure 4 and Figure 5 The shift fork 1102 includes two connected swing segments, the connection point of which is the middle part of the shift fork 1102. The two swing segments form a V-shape at an acute angle. The middle part of the shift fork 1102 is mounted on the positioning slide plate 1101 via a rotating support 1105. The rotating support 1105 includes a stepped shaft and a rotating bearing. The stepped shaft is perpendicular to the positioning slide plate (i.e., vertically along the Z direction). The middle part of the shift fork is sleeved on the stepped shaft via the rotating bearing, thereby enabling the middle part of the shift fork to rotate around the Z direction.

[0028] The fork and the sliding block are movably connected as follows: the end of the sliding block is provided with a groove, and the end of the fork is set in the groove by a pin, that is, the pin passes through the groove. Furthermore, in order to prevent unnecessary friction between the pin and the inner wall of the groove, a wear-resistant bushing or a bearing can be fitted on the pin. This structure satisfies the degree of freedom required for the rotation of the fork by allowing the pin to slide in the groove and rotate relative to the groove. The groove can be a U-shaped groove or a long strip groove. When a U-shaped groove is used, the sliding stroke of the sliding block (i.e., the telescopic power component two) needs to be controlled to prevent the pin from disengaging from the U-shaped groove.

[0029] by Figure 4Taking the upper fork as an example, in this embodiment, the principle of the fork and the swing fork clamping the material trolley is as follows: when the telescopic power component 1106 extends and drives the sliding block to move, it will drive the middle part of the fork 1102 to rotate counterclockwise around the Z direction, and the end of the fork 1102 away from the sliding block will swing away from the swing fork 1103 to achieve the release of the fork and the swing fork; when the telescopic power component 1106 retracts and drives the sliding block to move, it will drive the middle part of the fork 1102 to rotate clockwise around the Z direction, and the end of the fork 1102 away from the sliding block will swing towards the swing fork to achieve the clamping of the fork and the swing fork.

[0030] For preferred options, please refer to [link / reference]. Figures 4-6 The positioning slide plate 1101 is provided with a swing fork seat 1109, and the swing fork 1103 is rotatably mounted on the swing fork seat 1109. The swing fork 1103 achieves elastic rotation through a torsion spring 1112. The swing fork 1103 contacts the swing fork seat 1109 or the positioning slide plate 1101 at one end near the swing fork seat 1109 to limit the angle between the swing fork 1103 and the X-direction. β The maximum value.

[0031] Furthermore, in this embodiment, a swing fork seat 1109 is provided on each side of the swing fork (in some embodiments, the swing fork seat may be an integral structure, that is, a groove is opened in the middle of the swing fork seat for mounting the swing fork). The swing fork is rotatably mounted on the two swing fork seats 1109 via a mounting shaft 2 1113. At the same time, a torsion spring 1112 is sleeved on the mounting shaft 2. The torsion spring abuts against the inner cavity of the swing fork and the positioning slide plate 1101 (in some embodiments, it may abut against the bottom surface of the groove of the swing fork seat) to realize the torsion spring to reset the rotation of the swing fork, that is, the rotation of the swing fork makes the included angle β When the angle decreases, the torsion spring provides an elastic force that drives the oscillating fork to rotate, thus reducing the angle. β Restore to the maximum value.

[0032] When clamping of the material trolley is required, the positioning and correction component 110 moves to the bottom of the material trolley; during the movement, the swing fork may come into contact with obstacles at the bottom of the material trolley (such as clamping parts, structural components at the bottom of the material trolley, etc.), causing the swing fork to rotate passively (i.e., the included angle). β (Reduce); When it passes the clamping part at the bottom of the material trolley, the swing fork will return to its original position under the action of the torsion spring (the swing fork will also return to its original position when it passes the structural parts at the bottom of the material trolley). The swing fork, together with the shift fork, can clamp the clamping parts (such as beams, clamping blocks, etc.) at the bottom of the material trolley, thereby achieving the effect of clamping the material trolley on the positioning and correction component. The clamped material trolley will then move together with the positioning and correction component.

[0033] See Figure 6To intelligently indicate whether the material trolley is clamped, in this embodiment, the swing fork 1103 is provided with a detection device 1111 at one end face near the material trolley. The detection device 1111 is used to send an electrical signal when the fork 1102 and the swing fork 1103 clamp the material trolley. That is, when the fork and the swing fork clamp the material trolley, the detection device will send an electrical signal to the upper control unit to indicate that the clamping action has been completed. Preferably, the detection device can be a proximity switch or a photoelectric sensor, etc.

[0034] Please see Figure 2 , Figure 4 and Figure 5 In this embodiment, the positioning slide plate 1101 is slidably mounted on the ground rail base 111 via a slide rail 104, and the sliding block 1108 is slidably mounted on the positioning slide plate 1101 via a slide rail 2 1104. Preferably, the end of the slide rail 104 is provided with a limiting block 106 to prevent the positioning slide plate 1101 from detaching from the slide rail 104 during the sliding process.

[0035] Please see Figure 2 and Figure 4 The positioning slide plate 1101 is provided with a junction box 1107 for configuring the wiring of the electronic components on the positioning correction component 110; the ground rail base 111 is provided with a drag chain 105 to realize the wiring arrangement.

[0036] Please see Figures 2-5 The X-direction drive assembly includes a telescopic power component 107, a fixed rack 108, an idler wheel assembly 109, and a movable rack 1110 fixedly mounted on the back of the positioning slide plate 1101. The fixed rack 108 is fixedly mounted on the ground rail base 111. The telescopic power component 107 is mounted on the ground rail base 111, and its movable end is provided with an idler wheel assembly 109. The gear 1093 rotatably mounted in the idler wheel assembly 109 meshes with the fixed rack 108 and the movable rack 1110 on both sides of it.

[0037] like Figure 3As shown, the idler gear assembly 109 further includes an idler gear mounting base 1092 and a mounting shaft 1096 disposed on the idler gear mounting base 1092. The movable end of the telescopic power component 107 is connected to the idler gear mounting base 1092, and the gear 1093 is rotatably mounted on the mounting shaft 1096. Specifically, the movable end of the telescopic power component 1 is rotatably connected to the idler gear mounting base 1092 via a connecting pin 1091. The mounting shaft 1096 is vertically welded to the idler gear mounting base 1092. An idler gear bearing 1095 is provided on the mounting shaft 1096, and the end of the idler gear bearing is limited on the mounting shaft 1 by a retaining washer 1094. The retaining washer is fixed to the end of the mounting shaft 1 by a countersunk screw. The gear and the outer ring of the idler gear bearing are interference-fitted to realize the rotation of the gear around the centerline (i.e., the Z-axis) of the mounting shaft 1.

[0038] The X-direction drive assembly in this embodiment can double the movement stroke of the telescopic power component 107. For example, if the movement stroke of the telescopic power component 107 is 500mm, the fixed rack, moving rack and gear in this embodiment can achieve the effect of moving the positioning slide plate 1101 1000mm, which can reduce the stroke requirement of the telescopic power component 1.

[0039] Of course, in some embodiments, the X-axis drive assembly may only include telescopic power component one, which directly drives the positioning slide plate to slide on slide rail one 104; in some embodiments, the X-axis drive assembly may also include a drive motor (or hydraulic motor), gears and racks, and the cooperation of the drive motor, gears and racks can also drive the positioning slide plate to slide on slide rail one 104.

[0040] See Figure 2 The upper surface of the X-guide rail 102 is provided with wear-resistant strips 103, and the upper surface of the wear-resistant strips 103 has ramps at both ends in the X direction. The material trolley is supported and lifted by the upper surfaces of the wear-resistant strips 103 on the two X-guide rails 102. The ramps guide the material trolley onto the wear-resistant strips, reducing the difficulty of the material trolley moving to the upper surface of the wear-resistant strips. The support of the material trolley by the two wear-resistant strips ensures that the material trolley is in a horizontal state, which indirectly ensures that the workstation on the material trolley is also in a horizontal state, facilitating subsequent processing of the materials at the workstation.

[0041] Furthermore, the ground rail base 111 is provided with guide members 101 on both sides along the X direction, and the guide members are connected to the ground rail base 111 through connectors; the guide members 101 and the ground rail base 111 form a traveling channel for the material trolley. That is, during the process of the material trolley from entering the positioning ground rail to being supported and lifted by the wear-resistant strip, and then leaving the positioning ground rail, the traveling wheels of the material trolley pass through the traveling channel.

[0042] Furthermore, the ends of both guide members 101 are bent outwards, and the ends of the two guide members 101 form a flared opening; the ends of the X-guide rail 102 and the wear-resistant strip 103, as well as the corners of the ground rail base 111, are all provided with bevels. Figure 2 As shown, the end of a single guide member and the corner of the corresponding ground rail base also form a flared opening. The purpose of this arrangement is to facilitate the smooth entry of the material trolley's wheels into the travel channel. The purpose of setting the corner of the X-guide rail 102 at an angle is to facilitate the alignment of the material trolley's guide wheels with the X-guide rail 102, thereby reducing the difficulty for the material trolley to enter the positioning ground rail 100.

[0043] In this embodiment, both the first and second telescopic power components can be either electric cylinders or electric actuators, utilizing the precise displacement characteristics of electric cylinders or electric actuators to achieve the material position correction function; in some cases, the second telescopic power component may also be a hydraulic cylinder or a pneumatic cylinder.

[0044] Figures 7-13 This is a schematic diagram of the material trolley, which is used to supply film material to the film splicing equipment, enabling the continuous output of film material from the film splicing equipment, and assisting the working module of the film splicing equipment in completing the thermal bonding between the tail end of the previous roll of film and the head end of the next roll of film.

[0045] The material trolley 200 includes a trolley body 203 and n unwinding assemblies 202 and n working station assemblies, all of which are mounted on the trolley body 203 (i.e., the material trolley can hold n rolls of film at a time). The i-th unwinding assembly 202 is used to hold the i-th roll of film, and the i-th working station assembly is used to hold the first section of film material A01 released from the i-th roll of film. n is a natural number greater than or equal to 1, and i is a natural number and 1≤i≤n. Please see Figure 11 and Figure 12 The workstation assembly includes a workstation panel 2014 and a film pressing rod 2015. The workstation panel 2014 has a parallel lower cutting groove 2013 and a film pressing groove (not shown in the figure). The film pressing rod 2015 is movably disposed in the film pressing groove. After the film roll releases film material A01, the first section of film material A01 is placed on the workstation panel 2014, and the end of the first section of film material is placed in the film pressing groove. The film pressing rod 2015 applies pressure to the film material below it. When the external force on the film material is greater than the pressure applied by the film pressing rod 2015, film material A01 will be pulled out from below the film pressing rod 2015. Specifically, the lower cutting groove 2013 is used to cut the film material; that is, when the film roll has been supplied to the end section, the cutter on the working module moves down to the lower cutting groove to cut the film material.

[0046] The workstation panel is divided into panel one and panel two (not shown in the figure) by a lower cutting groove. Panel one and panel two cooperate with the working module to press the film material on both sides of the lower cutting groove. Panel one is also used for subsequent thermal bonding of the film with the working module. Panel one, together with the working module, presses the film material on one side of the lower cutting groove, while panel two, together with the working module, presses the film material on the other side of the lower cutting groove. Then, the cutter moves down into the lower cutting groove to cut the film material smoothly. Furthermore, to facilitate thermal bonding of the film, the film pressing groove is set on panel one, specifically on the side of panel one away from the lower cutting groove. The surface of panel two can be provided with multiple grooves to increase the contact area with the film during pressing.

[0047] Please see Figure 11 and Figure 12 The workstation assembly also includes k conveying rollers. The film material A01 released from the roll passes around the k conveying rollers in sequence and is placed on the upper surface of the workstation panel 2014. Here, k is a natural number greater than or equal to 1, and the highest point of the roller surface circle of the last conveying roller is flush with the upper surface of the workstation panel. Furthermore, the last conveying roller is located close to panel two. In this embodiment, the roller surface circle refers to the circle formed by the circumferential surface of the conveying roller, which is used to contact the film material. The highest point of the roller surface circle of the last conveying roller is flush with the upper surface of the workstation panel, which allows the film material to be directly laid horizontally onto panel two and panel one after it comes out from the last conveying roller (i.e., the film material laid on the workstation panel is tangent to the last conveying roller). Then, the end of the film material is placed in the pressing groove and pressed with a pressing rod to complete the installation of the film material on the material cart 200.

[0048] In this embodiment, a workstation assembly includes a first conveyor roller 2012 and a second conveyor roller 2016, wherein the second conveyor roller is the last conveyor roller closest to the workstation panel; by arranging the conveyor rollers, the film material can be tensioned and the film orientation can be adjusted.

[0049] Preferably, in this embodiment, the pressing rod 2015 is magnetically adsorbed in the pressing groove. At least one of the pressing groove or the pressing rod is equipped with a magnet, so that the pressing rod is magnetically adsorbed after being placed in the pressing groove. One end of the pressing rod and the pressing groove can be hinged, and the pressing rod can be pressed into and out of the pressing groove by rotating the pressing rod; alternatively, the pressing rod and the pressing groove can be connected only by magnetic adsorption, in which case the pressing rod can be completely removed from the pressing groove. Magnetic adsorption can apply a certain pressure to the film material below the pressing rod, but it is still sufficient to ensure that the external force on the film material (this external force is generated by the upward movement of the working module after the thermal bonding is completed; that is, after the thermal bonding of the film is completed, the upward movement of the working module will carry the film material away from the workstation panel) is greater than the pressure, so that the film material can be extracted from below the pressing rod.

[0050] In this preferred embodiment, the top of the vehicle body 203 is provided with m sets of film-attachment station assemblies 201 arranged along the X direction. Each film-attachment station assembly 201 includes a mounting frame 2011 and multiple sets of working station assemblies arranged along the length direction (Y direction) of the mounting frame 2011, where m is a natural number greater than or equal to 1. Preferably, n working station assemblies are generally evenly distributed across the m sets of film-attachment station assemblies. However, in some special cases, the number of working station assemblies on each film-attachment station assembly may be inconsistent. In this embodiment, there are two sets of film-attachment station assemblies, with four working station assemblies arranged on each film-attachment station assembly.

[0051] Please see Figure 9 The vehicle body 203 includes a chassis 2031 and handrails and an unwinding frame 2033, both mounted on the chassis 2031. The unwinding assembly 202 and the film splicing station assembly 201 are both mounted on the unwinding frame 2033. Specifically, the top of the unwinding frame 2033 has two sets of film splicing station assemblies 201, and each side of the unwinding frame 2033 has four unwinding assemblies 202. The handrails are used to facilitate the movement of the material cart by the operator.

[0052] Please see Figure 10 The unwinding assembly 202 includes an air shaft 2021, a rotary bearing 2023, an unwinding base plate 2024, and a magnetic damper 2025 disposed on the unwinding base plate 2024. The air shaft 2021 is rotatably mounted on the unwinding base plate 2024 via the rotary bearing 2023. The air shaft 2021 passes through the rotary bearing 2023 and the unwinding base plate 2024 and is connected to the magnetic damper 2025. Furthermore, the air shaft 2021 is provided with an unwinding disc 2022, and the end face of the film, after being sleeved on the air shaft 2021, abuts against the unwinding disc 2022.

[0053] In this embodiment, the unwinding base plate 2024 is fixed to the unwinding frame 2033 with screws. The air shaft 2021 is preferably a flange-type air shaft. The unwinding disc is set on the flange of the air shaft. After the film roll is sleeved on the air shaft, the air shaft clamps the film roll, and at the same time, the inner end face of the film roll (referring to the end face near the magnetic damper) abuts against the unwinding disc. The magnetic damper provides damping force to the rotation of the film roll, preventing the film roll from rotating freely and causing excessive release of film material, which would result in the film material not being in a taut state.

[0054] See Figure 8 The bottom of the vehicle body 203 is provided with multiple pairs of traveling wheels, at least one pair of guide wheels 206 and at least one pair of clamping blocks 208. The traveling wheels are used for the movement of the material trolley, the guide wheels 206 are used to guide the movement of the material trolley, and the clamping blocks 208 are used for the fork and swing fork to clamp the material trolley.

[0055] Furthermore, the bottom of the vehicle body is provided with a riser seat 209, and the traveling wheels are mounted on the riser seat 209. By adding the riser seat 209 to the bottom of the vehicle body, the clearance at the bottom of the vehicle body can be increased, which facilitates the installation of clamping blocks at the bottom of the vehicle body, without affecting the normal movement of the material cart. Specifically, in this embodiment, the traveling wheels include a pair of directional wheels 204 and a pair of omnidirectional wheels 205. The omnidirectional wheels 205 allow operators to easily adjust the direction of travel when pushing the material cart.

[0056] The guide wheel 206 is used to guide the forward movement of the material trolley, specifically to guide the movement of the material trolley on the X-axis guide rail of the positioning rail. After the film roll on the material trolley is installed, it needs to be manually pushed (or automatically driven, such as by an AGV) to the positioning rail. To ensure that the material trolley can smoothly enter the positioning rail, the guide wheel 206 needs to be set to roll in contact with the X-axis guide rail of the positioning rail to achieve motion guidance. The clamping block 208 is used to ensure that the positioning rail can smoothly clamp the material trolley. The fork and swing fork are moved to the clamping block of the material trolley and clamped. Then the material trolley can slide on the positioning rail with the fork and swing fork to realize the sliding of the working station component to the working position of the film attaching equipment; at the same time, each film attaching station component 201 also switches to the working position by following the movement of the fork and swing fork in the X direction.

[0057] Furthermore, to ensure the material trolley remains stationary during film bonding operations, the positioning rail fully supports the material trolley via wear-resistant strip one. When the material trolley is fully supported, the traveling wheels are suspended and do not provide support; the material trolley can only move along the positioning rail's forks and swing forks on wear-resistant strip one. Correspondingly, in this embodiment, a wear-resistant component 207 for supporting and lifting the material trolley is provided at the bottom of the trolley body 203. In the supported state, the wear-resistant component rests directly on wear-resistant strip one, and the material trolley is supported by wear-resistant strip one and the wear-resistant component. Furthermore, the wear-resistant component 207 includes a second wear-resistant strip 2071, a wear-resistant strip mounting bracket 2072, and anti-collision rollers 2073. Anti-collision rollers 2073 are provided at both ends of the wear-resistant strip mounting bracket 2072, and the second wear-resistant strip 2071 is disposed on the wear-resistant strip mounting bracket 2072.

[0058] Preferably, the second wear-resistant strip has inclined surfaces at both ends, and the bottom surface of the middle part of the second wear-resistant strip is lower than the bottom surface of the anti-collision roller (i.e., the anti-collision roller will be suspended in the air when supported). The inclined surface of the second wear-resistant strip, in conjunction with the slope of the first wear-resistant strip, effectively reduces the difficulty for the material trolley to climb onto the first wear-resistant strip. During the movement of the material trolley with the fork and swing fork, the anti-collision roller 2073 will first contact the slope of the first wear-resistant strip. During the movement, the anti-collision roller will slowly climb onto the slope of the first wear-resistant strip, and finally climb onto the upper surface of the first wear-resistant strip, thus completing the process of the material trolley completely climbing onto the first wear-resistant strip and being supported by it. The end of the second wear-resistant strip is set as an inclined surface to prevent the end of the second wear-resistant strip from pressing against the slope of the first wear-resistant strip during the process of the anti-collision roller climbing up the slope of the first wear-resistant strip, thus generating excessive movement resistance.

[0059] Figures 14-23 This is a schematic diagram of a film splicing device, which is used for the continuous transport of film rolls and for thermally bonding the tail section of the previous film roll with the head section of the next film roll.

[0060] The film splicing equipment includes a frame assembly 301, a Y-axis sliding module 302, a conveying assembly 307, a web guiding system 305, and a working module 304. The working module 304 includes a mounting frame 3041, a film splicing assembly 3042, and a Z-axis drive component 3045. The film splicing assembly 3042 is slidably mounted on the mounting frame 3041 along the Z-axis and driven by the Z-axis drive component 3045. The mounting frame 3041 is mounted on the frame assembly 301 via the Y-axis sliding module 302 to enable the working module 304 to slide along the Y-axis. The conveying assembly 307 is mounted on the frame assembly 301, and the web guiding system 305 is fixedly mounted between the working module 304 and the conveying assembly 307. The film material A01 conveyed by the film splicing assembly 3042 passes through the web guiding system 305 and the conveying assembly 307 in sequence before being output from the film splicing equipment 300.

[0061] See Figures 17-19 The film bonding assembly 3042 includes a film bonding frame B01, a cutter B05, a heat bonding module B06, and a pressing head B13, all disposed on the film bonding frame B01. The cutter B05 is mounted on the film bonding frame B01 via a cutter drive component B02 and is located between the heat bonding module B06 and the pressing head B13. The heat bonding module B06 includes a heating element and multiple air holes. Further, the air holes are used for vacuuming or supplying cooling gas; when vacuuming, the air holes adsorb the film material A01 onto the bottom surface of the heat bonding module B06; when supplying cooling gas, the air holes cool the bonding area of ​​the film material.

[0062] Since the cutter is located between the pressing head B13 and the heat bonding module B06, after the bonding assembly presses down on the film material and the cutter cuts the film material, part of the film material will be below the pressing head (i.e., the film material between the pressing head and panel two), and another part will be below the heat bonding module B06 (i.e., the film material between the heat bonding module and panel one). At this time, by drawing a vacuum through the air hole, the film material below the heat bonding module can be adsorbed onto the lower surface of the heat bonding module B06. The adsorbed part of the film material can then follow the movement of the heat bonding module and be thermally bonded to the first section of the film material of the next roll of film.

[0063] Furthermore, the membrane assembly 3042 is slidably disposed inside the mounting frame 3041 via the slide rail assembly B04, and a base plate for mounting the Z-axis drive member is provided on the mounting frame 3041. The movable end of the Z-axis drive member 3045 is connected to the top of the membrane assembly 3042 via a floating joint, thereby enabling the membrane assembly 3042 to slide along the Z-axis under the drive of the Z-axis drive member. Preferably, in this embodiment, the base plate is also provided with a vacuum generator 3044 and a control valve group 3046, thereby enabling vacuuming of the vent or delivery of cooling gas.

[0064] In this embodiment, the Z-axis drive component 3045 and the cutter drive component B02 are preferably one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder; the heating element is a heating wire. Furthermore, in this embodiment, a flexible material can be detachably provided at the bottom of the pressing head and the bottom of the heat-bonding module to contact the film material, thus protecting the film material. The flexible material can be a sponge. The structural form of the heat-bonding module may be adjusted due to different actual conditions. In this embodiment, the heating element is embedded in the mounting plate, which has air holes, and the mounting plate is disposed on the film bonding frame B01.

[0065] See Figure 19 The film splicing assembly 3042 further includes at least two conveying rollers located on the side of the heat-bonding module B06 away from the pressure head B13. The film material A01 passes through each conveying roller in sequence and is output from the film splicing assembly 3042. The film material is tensioned and its direction is changed on the film splicing assembly through each conveying roller. The last conveying roller is provided with a pressure block B12 driven by a pressure drive B07. When the pressure block B12 presses against the roller surface of the last conveying roller, the film material A01 on the roller surface is in a pressed state. The pressure block B12 is used to press the film material on the last conveying roller when the film material is cut, so that the film material is in a locked state.

[0066] Specifically, in this embodiment, the film-attaching assembly is equipped with a first conveyor roller B09, a second conveyor roller B10, and a third conveyor roller B11; wherein the third conveyor roller B11 is the last conveyor roller, and pressure blocks B12 are arranged at three points on the conveyor rollers to compress the film material. Figure 19As shown, when the membrane assembly presses down on the membrane material in preparation for cutting ( Figure 19 This illustrates a situation where the film-bonding assembly presses down on the film material but does not cut it. The film material from the material cart first passes through the bottom surface of the pressing head and the heat-bonding module, then passes between conveyor rollers one and two, and finally exits between the pressing block and conveyor roller three. When the film-bonding assembly does not press down on the film material, the film material is not pressed against the bottom surface of the pressing head and the heat-bonding module, but directly enters between conveyor rollers one and two, and then exits between the pressing block and conveyor roller three.

[0067] To ensure that the film material arriving from the material cart does not shift position and to promptly detect the edges and tail sections of the film material, the film splicing assembly 3042 in this embodiment further includes a correction sensor B08 for detecting the position of the film material on the splicing assembly, an edge detection sensor for detecting the edges of the film material, and a tail section detection sensor for detecting the tail section of the film material. Specifically, the correction sensor B08 is disposed inside the splicing frame B01, and the edge detection sensor and the tail section detection sensor are both disposed on the outer surface of the splicing frame B01, and both can be color mark sensors B03.

[0068] During the membrane conveying process, when the correction sensor B08 detects a deviation between the position of the conveying membrane material and the preset position, it can be adjusted by swinging the material trolley with the roll of film in the X direction (i.e., to correct the position of the membrane material in the section from the material trolley to the film bonding assembly). The tail section detection sensor sends an electrical signal to stop the film feeding device when it detects the tail section mark of the roll of film. There are two edge detection sensors. As the material trolley moves along the X direction to the bottom of the film bonding assembly, the two edge detection sensors will detect the edge of the membrane material at the station in sequence. When the first edge detection sensor detects the edge of the membrane, it controls the material trolley to slow down. When the second edge detection sensor detects the edge of the membrane, it controls the material trolley to stop moving.

[0069] Please see Figure 16In this embodiment, the Y-axis sliding module 302 includes a mounting base plate 3021, a driving mechanism, slide rails 3026, and sliders 3027. Two slide rails 3026 are arranged parallel to each other on the mounting base plate 3021, and at least one slider 3027 is slidably mounted on each slide rail. The mounting frame 3041 is connected to the sliders on the two slide rails to achieve sliding of the mounting frame along the Y-axis. In this embodiment, the driving mechanism includes a Y-axis driving component 3022, a drive wheel 3023, a conveyor belt 3024, and a driven wheel 3025. A set of drive wheels and driven wheels are provided on both sides of the mounting base plate, and the drive wheels and driven wheels are connected by a conveyor belt. The Y-axis driving component 3022 connects to two drive wheels simultaneously, thereby achieving synchronous movement of the two conveyor belts. The mounting frame is fixedly connected to the conveyor belt via a connecting seat, thereby enabling the mounting frame to move driven by the conveyor belt.

[0070] Furthermore, the passive wheel 3025 can be movably mounted to achieve the effect of tensioning the conveyor belt. The movably mounted passive wheel structure is a conventional method in the art and will not be described in detail in this embodiment. The mounting base plate 3021 is fixed to the upper part of the frame assembly 301 by bolts. The Y-axis drive assembly 3022 is a combination of a motor and a reducer, or a hydraulic motor.

[0071] In some embodiments, the drive mechanism may be one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder, or it may be a drive form using a motor in conjunction with gears and racks. In other embodiments, the mounting base plate 3021 may not be required; instead, the slide rail 3026 and the drive mechanism may be directly mounted on the frame assembly 301. Furthermore, the mounting frame 3041 is also provided with a sensing block 3043, which, in conjunction with a proximity switch, can control the sliding stroke of the mounting frame 3041 in the Y direction.

[0072] Please see Figures 21-23 The conveying assembly 307 includes a conveying frame C01 and a membrane tension detection assembly and an output roller assembly, both of which are disposed on the conveying frame C01; the membrane material passes through the membrane tension detection assembly and the output roller assembly in sequence and is then output from the film splicing device 300.

[0073] Specifically, the membrane tension detection assembly includes a passive roller C02, a tension detection roller C03, a passive roller C04, and a tension detection element C08. Both ends of the tension detection roller C03 are mounted on the conveying frame C01 via the tension detection element C08. The passive rollers C02 and C04 are located on both sides of the tension detection roller C03. Further, the tension detection element C08 is a tension sensor, one end of which is fixedly mounted on the conveying frame C01 via a mounting base, and the other end is connected to the tension detection roller C03.

[0074] Specifically, the output roller assembly includes a passive roller three C05, an output drive roller C06, and an output drive component C07. The passive roller three C05 and the output drive roller C06 are arranged side by side on the conveying frame C01. The output drive component C07 is disposed on the conveying frame C01, and its output end is connected to one end of the output drive roller C06. The passive roller three C05 is elastically floating on the conveying frame C01, so that the passive roller three C05 presses against the output drive roller C06, thereby ensuring that the driving force of the output drive component can act on the film material. Preferably, the output drive component C07 is a combination of a motor and a reducer, or a hydraulic motor.

[0075] See Figure 22 In this embodiment, the specific structure of the passive roller three C05 elastically floating setting is as follows: the conveying frame C01 is provided with a guide hole C11, and the two ends of the passive roller three C05 are respectively slidably disposed in the guide hole C11; the conveying frame C01 is provided with a mounting block C13, the mounting block C13 is provided with a screw C09, and the end of the screw freely passes through the end of the passive roller three; an adjusting nut C10 is sleeved on the screw, and a spring is provided between the adjusting nut and the end of the passive roller three, and the spring is sleeved on the screw; by turning the adjusting nut C10, the compression degree of the spring is adjusted, thereby realizing that the passive roller three is pressed against the output drive roller C06 under the action of the spring.

[0076] See Figure 23 The flow path of the film material in the conveying assembly 307 is as follows: after the film material comes out of the working module, it first enters the space between the passive roller 1 C02 and the tension detection roller C03, then passes the tension detection roller C03, and enters the space between the tension detection roller and the passive roller 2 C04 to be output between the passive roller 3 C05 and the output drive roller C06.

[0077] See Figure 14 and Figure 15 The frame assembly has a portal-shaped structure. The inner side of the lower end of each of the two legs of the frame assembly 301 is provided with a clamping assembly 306. The clamping assembly 306 is used to apply a downward clamping force to the material trolley. The material trolley slides from the X direction to the bottom of the frame assembly via the positioning rail. After reaching the working position, the clamping assembly fixes the material trolley in the supported and lifted state on the positioning rail. When the clamping assembly 306 is released, the material trolley can be driven by the positioning rail to move in the X direction.

[0078] Specifically, the clamping assembly 306 includes a clamping drive 3061, a fixed bracket 3062, and a clamping seat 3063. The clamping drive 3061 is mounted on the frame assembly 301 via the fixed bracket 3062. The clamping seat 3063 is driven to rotate by the clamping drive 3061. The clamping surface of the clamping seat 3063 is provided with clamping rollers 3064. By rotating the clamping seat, the clamping rollers 3064 are pressed onto the material trolley, thereby applying a downward clamping force to the material trolley.

[0079] The correction system 305 is a purchased existing product. Its operation corrects the position of the film material conveyed by the working module. In this embodiment, the correction system can be mounted on the frame assembly or on the mounting base 3021 in the Y-axis sliding module. Preferably, the top surface of the frame assembly 301 is provided with a cantilever cabinet mounting base 303 for mounting the control box. The control box is rotatably mounted on the cantilever cabinet mounting base 303 via a cantilever, allowing operators to easily rotate the control box to the operating position as needed.

[0080] Figures 24-27 The diagram illustrates the structure of a buffer device, which is positioned between the film-attaching equipment and the film-using equipment to buffer the film between film feeding and film use. The film-attaching equipment supplies film material A01 to the buffer device, while the film-using equipment extracts film material from the buffer device for use under the drive of internal equipment.

[0081] See Figures 24-27 The buffer device includes a buffer frame 401 and a tension roller group 403 and a tension roller group 409, both of which are disposed on the buffer frame 401; the tension roller group 403 is located above the tension roller group 409, and the tension roller group 409 is slidably disposed on the buffer frame 401. Furthermore, both tension roller assembly one 403 and tension roller assembly two 409 include multiple tension rollers arranged in a row. The film material A01 is alternately wound between the tension rollers on tension roller assembly one 403 and tension roller assembly two 409, such as... Figure 26 As shown, the tension rollers on tension roller group 1 403 and tension roller group 2 409 can rotate under the drive of the film material A01.

[0082] Specifically, in this embodiment, the tension roller group 1 403 includes a plurality of tension rollers 4002 arranged in a row, and the tension roller group 2 409 includes a plurality of tension rollers 4004 arranged in a row. The number of tension rollers 1 in tension roller group 1 and the number of tension rollers 2 in tension roller group 2 can be the same or different. The more tension rollers 1 and tension rollers 2 there are, the more film material can be buffered between tension roller groups 1 and 2.

[0083] The tension roller assembly 409 is according to The relationship with G slides on cache frame 401; where The speed at which membrane material A01 enters the buffer device The speed at which membrane material A01 is output from the buffer device The force generated by the speed difference between them, G, is the weight of the tension roller assembly 409. Therefore, it can be known that... During the operation of the buffer device, the speed of the membrane material input and output will dynamically change. The rule of change is: when ≥ hour, ,but ;when < hour, , and The larger the difference, the better. The larger. Specifically, when When it equals G, tension roller assembly 409 remains stationary; when When the value is greater than G, tension roller group two 409 will slide upward (at this time, tension roller group one and tension roller group two will move closer to each other), and the buffered film material will be used; when When the value is less than G, tension roller group 2 409 will slide downward (at this time, tension roller group 1 and tension roller group 2 will move away from each other), and the film material will be buffered.

[0084] For further details, please see Figure 24 and Figure 25 The buffer frame 401 is provided with a Z-guide rail 407, and the tension roller assembly 409 is slidably disposed on the Z-guide rail 407. The Z-guide rail 407 is vertically disposed, which can ensure the smoothness and accuracy of the movement of the tension roller assembly 409 and reduce the sliding resistance.

[0085] Furthermore, the tension roller assembly 403 is slidably mounted on the Z-guide rail 407, and its movement and stopping on the Z-guide rail 407 are achieved by a driving device. Specifically, tension roller assembly 1 and tension roller assembly 2 can be mounted on the same pair of Z-guide rails 407, or they can be mounted on separate Z-guide rails 407 to achieve movement for both. In this embodiment, tension roller assembly 1 and tension roller assembly 2 are mounted on the same pair of Z-guide rails 407; the driving device can achieve sliding and stopping of tension roller assembly 1 on the Z-guide rail. In this embodiment, stopping refers to tension roller assembly 1 being stationary on the Z-guide rail, that is, locking the position of tension roller assembly 1 on the Z-guide rail 407 when the driving device does not provide driving force. Tension roller assembly one is also set to a sliding form, which can reduce the difficulty of film winding of the buffer device. When winding the film, tension roller assembly one can be slid to a lower position to facilitate the worker to wind the film. After the film winding is completed, tension roller assembly one can be slid to the highest position to maintain sufficient distance between tension roller assembly one and two to buffer the film material.

[0086] Please see Figure 24 , Figure 25 , Figure 27 In this embodiment, the driving device includes a chain 414 and a passive sprocket assembly 405 and a drive sprocket assembly 413, both mounted on the buffer frame 401. The chain 414 connects the passive sprocket assembly 405 and the drive sprocket assembly 413, and the tension roller assembly 403 is fixedly connected to the chain 414. That is, the drive sprocket assembly 413 drives the chain to move, thereby enabling the tension roller assembly 403 to slide on the Z-guide rail.

[0087] In this embodiment, the passive sprocket assembly 405 is located at the upper end of the buffer frame 401, and the drive sprocket assembly 413 is located at the lower end of the buffer frame 401. In some embodiments, the positions of the passive sprocket assembly and the drive sprocket assembly may be interchanged, with the same effect. The passive sprocket assembly and the drive sprocket assembly have similar structures; the drive sprocket assembly is simply different from the passive sprocket assembly by having an additional drive mechanism. Figure 27The illustration shows a drive sprocket assembly, which includes a sprocket 4131, a support assembly 4132, a rotating shaft 4136, a fixed plate 4133 serving as a drive device, a torque arm 4134, and a rotary drive component 4135. The two ends of the rotating shaft 4136 are respectively mounted on the support assembly 4132 to allow free rotation of the shaft. The sprocket 4131 is located at one end of the rotating shaft 4136, and the chain 414 meshes with the sprocket 4131. The other end of the rotating shaft is fitted with the rotary drive component 4135 (in this embodiment, the rotary drive component is a worm gear reducer and a drive motor). The rotary drive component 4135 is fixed to the fixed plate 4133 via the torque arm 4134. The fixed plate is fixed to the buffer frame. The torque arm and the fixed plate prevent the rotary drive component from rotating on its own, thus achieving a fixing effect. The support assembly includes a bearing seat and a bearing, which is conventional technology in this field and will not be described in detail here.

[0088] Of course, in some embodiments, the driving device can also be a telescopic power component, one end of which is connected to the tension roller assembly 403, and the other end is connected to the buffer frame 401. The telescopic power component can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder, etc.

[0089] Please see Figure 24 and Figure 25 A distance sensor 406 is provided on the top of the buffer frame 401 or on the tension roller group 403, and a reflector 408 corresponding to the distance sensor 406 is provided on the tension roller group 409. By detecting the position of the tension roller group 2 by the distance sensor 406, the amount of film material buffered can be determined, thereby adjusting the film feeding speed of the film splicing equipment. Since the tension roller group 1 is in its highest position when the buffer device is working, installing the distance sensor on the tension roller group 1 can also achieve the required function.

[0090] Preferably, the buffer frame 401 is provided with a feed roller group 402 for the film material to enter the buffer device and a discharge roller group 410 for the film material to exit the buffer device. The feed roller group 402 includes two feed rollers 4001 arranged in parallel, and the film material A01 enters the buffer device between the two feed rollers 4001. The discharge roller group 410 includes two discharge rollers 4003 arranged in parallel, and the film material A01 is output between the two discharge rollers 4003. In this embodiment, neither the feed rollers 4001 nor the discharge rollers 4003 are equipped with a drive device to achieve self-rotation; they both rotate following the movement of the film material. Of course, in some embodiments, a drive device may be added to the feed rollers and / or the discharge rollers to achieve traction for the input and / or output of the film material.

[0091] See Figure 25The lower end of the buffer frame 401 is provided with a limiter 412 for limiting the tension roller assembly 409. The limiter restricts the lowest position of the tension roller assembly, thus controlling the maximum amount of film that the buffer device can hold. Furthermore, the top of the buffer frame 401 is evenly provided with multiple lifting rings 404, and the bottom is evenly provided with multiple foot cups 411. The lifting rings facilitate the hoisting of the buffer device, while the foot cups allow for adjustment of the device's height.

[0092] In this embodiment, the X, Y, and Z directions are perpendicular to each other.

[0093] The working principle of the film supply device in this embodiment is as follows: After loading the material trolley and laying the first section of film material released from each roll on each workstation assembly, the material trolley is transported to the bottom of the film splicing equipment via a positioning rail for film material supply. In a single set of film splicing workstation assemblies, the film material on each workstation assembly is spliced ​​sequentially by sliding the working module along the Y direction. Between each film splicing workstation assembly, the material trolley is slid along the X direction via a positioning rail to sequentially switch to the work area of ​​the working module. At the same time, the position of the film material on the workstation can also be corrected and adjusted by sliding the material trolley along the X direction via the positioning rail.

[0094] In this embodiment, the method by which the film supply equipment joins the tail section of the previous film roll with the head section of the next film roll in a single film splicing station assembly is as follows: Step 1: The film splicing equipment conveys the film material A01 from the previous roll of film. When the working module detects that the roll of film has been supplied to the end, it stops conveying the film material (i.e., both the conveying component and the working module stop conveying the film material); the film splicing component 3042 moves downward along Z and presses the film material onto the lower station panel through the film pressing head B13 and the heat splicing module B06 (at this time, the pressure block presses the film material tightly onto the last conveyor roller). Step 2: The cutter B05 in the film bonding assembly 3042 cuts the film material, and the heat bonding module B06 vacuum adsorbs the film material below it through the air hole. Then the film bonding assembly 3042 moves upward along Z. Step 3: The working module 304 moves along the Y direction, so that the heat bonding module B06 moves with the adsorbed film material to the top of the next station panel; then the film bonding assembly 3042 moves downward along the Z direction, so that the film material adsorbed by the heat bonding module is pressed together with the first section of the film material of the next roll of film on the lower station panel. Step 4: The heating element in the heat bonding module B06 releases heat energy, which allows the two layers of film to be thermally bonded; after the heat bonding is completed, the heat bonding module B06 blows cooling gas to the thermal bonding position of the film through the air hole to dissipate heat, and the film bonding assembly 3042 stops after moving upward along Z (during the upward movement of the film bonding assembly, the end of the first section of film material below the pressure rod is pulled out). Step 6: The film splicing equipment resumes the conveying of film material A01.

[0095] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
