Description

Technical Field

[0001] The invention relates to the technical field of film material composite processing, in particular to a film material positioning device and film material composite equipment. Background Art

[0002] In the manufacturing process of fuel cells, the lamination of two or more layers of membrane materials is a common production process. For example, in the production of membrane electrode (MEA), multiple layers of membrane materials with hot melt adhesive are pressed together by pressurization and heating. In order to increase production capacity, continuous roll-to-roll lamination process has become a trend. However, since the membrane materials generally need to be cut before lamination, especially when the hollow area in the middle of the membrane material is large, the roll-to-roll lamination can easily cause the product to warp and wrinkle, resulting in misalignment between the membrane materials, and the appearance and precision of the finished product cannot meet the design requirements. Summary of the invention

[0003] Based on this, it is necessary to provide a membrane positioning device and membrane composite equipment to improve the above defects, in order to address the problem that in the prior art, the membrane materials generally need to be cut before being composited. In particular, when the hollow area in the middle of the membrane material is large, the rolling of the rollers can easily cause the product to warp and wrinkle, thereby causing misalignment between the membrane materials, and the appearance and precision of the finished product cannot meet the design requirements.

[0004] A film material positioning device, comprising:

[0005] Base;

[0006] A positioning assembly, comprising a first molding mechanism and a second molding mechanism relatively arranged on the base, the first molding mechanism and the second molding mechanism can approach or move away from each other, the first molding mechanism has an avoidance portion, the second molding mechanism has a positioning portion corresponding to the avoidance portion, and in the process of the second molding mechanism approaching the first molding mechanism, the positioning portion sequentially penetrates the positioning holes on at least two layers of film materials and is inserted into the corresponding avoidance portion; and

[0007] A traction roller assembly is arranged at the downstream side of the positioning assembly, and the traction roller assembly comprises a base, a connecting piece, a driven roller and an active roller, wherein the connecting piece is movably connected to the base, the driven roller is mounted on the connecting piece, and the active roller is mounted on the base;

[0008] The connecting member is in transmission connection with the first molding mechanism, and when the first molding mechanism approaches the second molding mechanism, the connecting member can drive the connecting member to separate the driven clamping roller from the active clamping roller; when the first molding mechanism moves away from the second molding mechanism, the connecting member can drive the driven clamping roller to abut against the active clamping roller.

[0009] In one embodiment, the connecting member is rotatably connected to the base, and the first molding mechanism can push the connecting member when approaching the second molding mechanism, so that the connecting member rotates and drives the driven clamping roller to separate from the active clamping roller.

[0010] In one of the embodiments, the traction clamp roller assembly further includes an elastic member, which is connected to the base and the connecting member to provide a pre-tightening force that causes the connecting member to rotate and drive the driven clamp roller to abut against the active clamp roller.

[0011] In one embodiment, the first molding mechanism includes a support frame, a first template, a first driving member and a lever;

[0012] The support frame can be connected to the base towards or away from the second molding mechanism, the first template is fixedly connected to the support frame, and the avoidance portion is provided on a side facing the second molding mechanism, and the first driving member is connected to the base and the support frame;

[0013] The shifting rod is connected to the supporting frame, and the connecting member is located on a moving path of the shifting rod along with the supporting frame approaching the second molding mechanism.

[0014] In one embodiment, the second molding mechanism includes a fixing seat, a second mold plate and a second driving member;

[0015] The fixing seat is fixedly connected to the base, the second template can be connected to the fixing seat close to or away from the first molding mechanism, and the side facing the second molding mechanism has the positioning part; the second driving member is arranged on the fixing seat and is transmission-connected to the second template.

[0016] In one embodiment, the film material positioning device also includes a dotting component, which includes a mounting seat and a dotting block. The mounting seat is arranged on the base, and the dotting block can be connected to the mounting seat close to or away from the second molding mechanism. When the dotting block approaches the second molding mechanism, it can heat and dot at least two layers of the film material.

[0017] In one embodiment, the dotting assembly further includes an adsorption support plate, which can be connected to the mounting base to move closer to or farther away from the second molding mechanism. The adsorption support plate can adsorb and fix at least two layers of the film material in the process of moving closer to the second molding mechanism.

[0018] In one embodiment, the film material positioning device also includes a die-cutting assembly disposed on the base, wherein the die-cutting assembly is located on the downstream side of the positioning assembly and is used to cut at least one layer of the at least two layers of the film material away from the base into film sheets.

[0019] In one embodiment, the film positioning device further comprises a first adsorption component and a waste collection component disposed on the base, wherein the first adsorption component is reciprocally movably connected to the base along the film conveying direction, and the waste collection component is located at the downstream side of the die-cutting component;

[0023] In the actual operation of the above-mentioned film material positioning device and film material composite equipment, first, the driven clamping roller abuts against the active clamping roller, so that at least two layers of film materials pass between the first molding mechanism and the second molding mechanism under the traction of the active clamping roller. Then, the first molding mechanism moves toward the second molding mechanism, thereby driving the connecting member to drive the driven clamping roller to separate from the active clamping roller, so that the first active clamping roller cannot pull the layers of film materials, that is, at this time, at least two layers of film materials between the first molding mechanism and the second molding mechanism stop moving downstream. Then, the second molding mechanism moves toward the first molding mechanism, so that the positioning part on the second molding mechanism passes through the pre-processed positioning holes on each layer of film material in turn, and is inserted into the corresponding avoidance part, that is, the positioning part is used to position each layer of film material. Finally, the second molding mechanism moves away from the first molding mechanism and resets (at this time, the positioning part withdraws from the avoidance part and the positioning holes on each layer of the membrane material in turn), and the first molding mechanism moves away from the second molding mechanism and resets, so that the connecting part drives the driven clamping roller to rest against the active clamping roller. At this time, the active clamping roller pulls each layer of the membrane material to continue to be transported downstream, so as to facilitate subsequent roller pressing and compounding.

[0024] In this way, the connecting parts are used to realize the linkage cooperation between the first molding mechanism and the driven clamping roller, so as to realize the positioning and traction of each layer of the membrane material and realize the positioning of each layer of the membrane material during the conveying process, thereby improving the positioning accuracy between each layer of the membrane material, which is beneficial to improve the warping, wrinkling, dislocation and other phenomena of the membrane material during roller pressing and compounding.

[0039] See also Figure 1 An embodiment of the present invention provides a film positioning device for positioning at least two layers of film a before rolling and laminating the at least two layers of film a. The film positioning device includes a base 10, a positioning assembly (not shown) and a traction roller assembly 30.

[0040] The positioning assembly includes a first molding mechanism 20a and a second molding mechanism 20b which are arranged on the base 10, and the first molding mechanism 20a and the second molding mechanism 20b are arranged relatively. The first molding mechanism 20a and the second molding mechanism 20b can approach or move away from each other, and the first molding mechanism 20a has an avoidance portion (not shown), and the second molding mechanism 20b has a positioning portion 220 corresponding to the avoidance portion. In the process of the second molding mechanism 20b approaching the first molding mechanism 20a, the positioning portion 220 sequentially penetrates the positioning holes on at least two layers of film material a and is inserted into the corresponding avoidance portion. The traction clamping roller assembly 30 is arranged on the downstream side of the positioning assembly. The traction clamping roller assembly 30 includes a base 31, a connecting member 32, a driven clamping roller 33 and an active clamping roller 34. The connecting member 32 is movably connected to the base 31, the driven clamping roller 33 is rotatably connected to the connecting member 32 around its own axis, and the active clamping roller 34 is rotatably connected to the base 31 around its own axis.

[0041] The connecting member 32 is in transmission connection with the first molding mechanism 20a. When the first molding mechanism 20a approaches the second molding mechanism 20b, the connecting member 32 can be driven to drive the driven clamping roller 33 to separate from the active clamping roller 34, so that the active clamping roller 34 cannot pull the layers of film material a between the active clamping roller 34 and the driven clamping roller 33 to move downstream. When the first molding mechanism 20a moves away from the second molding mechanism 20b, the connecting member 32 can drive the driven clamping roller 33 to abut against the active clamping roller 34, so that the active clamping roller 34 pulls the layers of film material a between the active clamping roller 34 and the driven clamping roller 33 to move downstream. Optionally, the positioning portion 220 can be a positioning pin. The avoidance portion can be an avoidance groove or an avoidance hole.

[0042] When the above-mentioned film material positioning device is actually in operation, first, the driven clamping roller 33 abuts against the active clamping roller 34, so that at least two layers of film materials pass between the first molding mechanism 20a and the second molding mechanism 20b under the traction of the active clamping roller 34. Then, the first molding mechanism 20a moves toward the second molding mechanism 20b, thereby driving the connecting member 32 to drive the driven clamping roller 33 to separate from the active clamping roller 34, so that the first active clamping roller 34 cannot pull each layer of film material a, that is, at this time, at least two layers of film material a between the first molding mechanism 20a and the second molding mechanism 20b stop moving downstream. Then, the second molding mechanism 20b moves toward the first molding mechanism 20a, so that the positioning part 220 on the second molding mechanism 20b sequentially penetrates the pre-processed positioning holes on each layer of film material a, and is inserted into the corresponding avoidance part, that is, the positioning part 220 is used to position each layer of film material a. Finally, the second molding mechanism 20b moves away from the first molding mechanism 20a and resets (at this time, the positioning portion 220 sequentially withdraws from the avoidance portion and the positioning holes on each layer of membrane material a), and the first molding mechanism 20a moves away from the second molding mechanism 20b and resets, so that the connecting member 32 drives the driven clamping roller 33 to abut against the active clamping roller 34. At this time, the active clamping roller 34 pulls each layer of membrane material to continue to be transported downstream to facilitate subsequent roller pressing and compounding.

[0043] In this way, the connecting piece 32 is used to realize the linkage cooperation between the first molding mechanism 20a and the driven clamping roller 33, so as to realize the positioning and traction of each layer of the membrane material a, and realize the positioning of each layer of the membrane material a during the conveying process, thereby improving the positioning accuracy between each layer of the membrane material a, which is beneficial to improve the warping, wrinkling, misalignment and other phenomena of the membrane material during roller pressing and compounding.

[0044] It should be noted that the five-in-one molding is the most important intermediate link in the preparation of membrane electrode and the core process of hydrogen fuel cells. The five-in-one material strip consists of a three-in-one, an upper frame and a lower frame. Generally, the upper frame can be one or two layers, and the lower frame can also be one or two layers. Therefore, the five-in-one molding process is a composite of two or four layers of frames (including one or two layers of upper frames and one or two layers of lower frames) and three-in-one. The rolling device of the present invention can be applied to the composite of three-in-one and two or four layers of frames.

[0045] See also Figure 1 and Figure 2 In the embodiment of the present invention, the connecting member 32 is rotatably connected to the base 31, and the first molding mechanism 20a can push the connecting member 32 when it moves toward the second molding mechanism 20b, so that the connecting member 32 rotates and drives the driven clamping roller 33 to separate from the active clamping roller 34. In this way, the rotation of the connecting member 32 is used to drive the driven clamping roller 33 and the active clamping roller 34 to abut or separate, so that the switching between the mutually abutting and separating states of the driven clamping roller 33 and the active clamping roller 34 is stable and reliable.

[0046] Furthermore, the traction clamp roller assembly 30 further includes an elastic member 35. The elastic member 35 is connected to the base 31 and the connecting member 32 to provide a preload force that causes the connecting member 32 to rotate and drive the driven clamp roller 33 to abut against the active clamp roller 34. In this way, when the first molding mechanism 20a moves away from the second molding mechanism 20b, the connecting member 32 rotates under the action of the preload force provided by the elastic member 35, so that the driven clamp roller 33 abuts against the active clamp roller 34. Optionally, the elastic member 35 can be a spring.

[0047] Specifically in the embodiment, the connecting member 32 includes a connecting portion 321 and a reinforcing portion 322. The connecting portion 321 includes two connecting portions 321, the two connecting portions 321 are rotatably connected to the base 31 around the same rotation axis, the reinforcing portion 322 is connected between the two connecting portions 321, and the opposite ends of the driven clamping roller 33 are rotatably connected to the two connecting portions 321 around their own axes. When the first molding mechanism 20a approaches the second molding mechanism 20b, it can push the two connecting portions 321, so that the two connecting portions 321 rotate around the rotation axis and drive the driven clamping roller 33 to separate from the active clamping roller 34.

[0048] Specifically in the embodiment, the traction roller assembly 30 further includes a traction drive 36, which is disposed on the base 31 and is transmission-connected to the active roller 34 to drive the active roller 34 to rotate around its own axis. Optionally, the traction drive 36 can be a motor.

[0049] See also Figure 1 , Figure 3 and Figure 4 In an embodiment of the present invention, the first molding mechanism 20a includes a support frame 21a, a first template 22a, a first driving member 23a and a lever 24a. The support frame 21a can be connected to the base 10 to move closer to or farther from the second molding mechanism 20b. The first template 22a is fixedly connected to the support frame 21a, and the above-mentioned avoidance portion is provided on the side facing the second molding mechanism 20b. The first driving member 23a is connected to the base 10 and the support frame 21a to drive the support frame 21a to move closer to or farther from the second molding mechanism 20b relative to the base 10. The lever 24a is connected to the support frame 21a, and the connecting member 32 is located on the moving path of the lever 24a as the support frame 21a moves closer to or farther from the second molding mechanism 20b. Thus, when the first driving member 23a drives the support frame 21a to approach the second molding mechanism 20b, the lever 24a on the support frame 21a pushes the connecting member 32, so that the connecting member 32 rotates and drives the driven clamping roller 33 to separate from the active clamping roller 34. Optionally, the first driving member 23a can be a cylinder.

[0050] In an embodiment of the present invention, the second molding mechanism 20b includes a fixed seat 21b, a second template 22b and a second driving member 23b. The fixed seat 21b is fixedly connected to the base 10, and the second template 22b can be connected to the fixed seat 21b to move closer to or farther from the first molding mechanism 20a, and the side facing the second molding mechanism 20b has the above-mentioned positioning portion 220. The second driving member 23b is arranged on the fixed seat 21b, and is transmission-connected with the second template 22b to drive the second template 22b to move closer to or farther from the first molding mechanism 20a. In this way, when it is necessary to position each layer of film material a, the second driving member 23b drives the second template 22b toward the first molding mechanism 20a, so that the positioning portion 220 on the second template 22b sequentially passes through the positioning holes on each layer of film material a, and is inserted into the avoidance portion of the second molding mechanism 20b. When one positioning is completed, the second driving member 23b drives the second template 22b away from the first molding mechanism 20a, so that the positioning portion 220 on the second template 22b sequentially exits the avoidance portion and the positioning holes of each layer of film material a. Optionally, the avoidance portion on the first template 22a and the positioning portion 220 on the second template 22b can include multiple avoidance portions and multiple positioning portions 220 correspond one to one.

[0051] See also Figure 1 and Figure 5 As shown, in an embodiment of the present invention, the film material positioning device further includes a dotting assembly 40, and the dotting assembly 40 includes a mounting seat 41 and a dotting block 42. The mounting seat 41 is arranged on the base 10, and the dotting block 42 can be connected to the mounting seat 41 close to or away from the second molding mechanism 20b. The dotting block 42 can heat and dot at least two layers of film material a in the process of moving close to the second molding mechanism 20b. In this way, after the positioning portion 220 passes through the positioning holes of each layer of film material a and is inserted into the avoidance portion (that is, after positioning each layer of film material a), the dotting block 42 can be controlled to move toward the second molding mechanism 20b, so that the dotting block 42 contacts the film material a and the layers of film material a in the contact area are hot-melt connected, thereby preventing the positioned layers of film material a from being misaligned during roller pressing and compounding. It is understandable that the dotting block 42 needs to be heated and kept warm by a heating device so that when the dotting block 42 contacts the film material a, the hot melt adhesive between the layers of the film material a can be melted to achieve connection between the layers of the film material a.

[0052] Furthermore, the dotting assembly 40 further includes a third driving member 43, which is disposed on the mounting seat 41 and is transmission-connected to the dotting block 42 to drive the dotting block 42 to move closer to or away from the second molding mechanism 20b. Optionally, the third driving member 43 may be a cylinder.

[0053] Specifically in the embodiment, the dotting assembly 40 further includes an adsorption support plate 44, which can be connected to the mounting seat 41 to move closer to or further away from the second molding mechanism 20b. When the adsorption support plate 44 moves closer to the second molding mechanism 20b, it can adsorb and fix at least two layers of film material a, so that the dotting block 42 can heat and dot each layer of film material a. Optionally, the adsorption support plate 44 can be a vacuum adsorption support plate 44.

[0054] Furthermore, the dotting assembly 40 further includes a fourth driving member (not shown), which is disposed on the mounting seat 41 and is transmission-connected to the adsorption support plate 44 to drive the adsorption support plate 44 to move closer to or away from the second molding mechanism 20b. Optionally, the fourth driving member may be a cylinder.

[0055] Specifically in the embodiment, the base 10 is provided with an adjustment rail b extending longitudinally along the conveying direction of at least two layers of film material a, and the mounting seat 41 is slidably connected to the adjustment rail b. In this way, the mounting seat 41 can be controlled to slide along the adjustment rail b to adjust the position of the dotting block 42.

[0056] In an embodiment of the present invention, the film positioning device also includes a die-cutting assembly 50 disposed on the base 10, and the die-cutting assembly 50 is located on the downstream side of the positioning assembly, and is used to cut at least one layer of the at least two layers of film material a away from the base 10 into film sheets. Since each layer of the film material a is heated and dotted, the film sheet formed by cutting is fixedly connected to the film material a that has not been cut. Preferably, the die-cutting assembly 50 is used to cut the other layers of the film material a except the layer of the film material a closest to the base 10 between the first molding mechanism 20a and the second molding mechanism 20b into film sheets. In other words, only the layer of the film material a closest to the base 10 is not cut, and the remaining layers of the film material a are cut into film sheets arranged in sequence along the length direction of the film material. In this way, part of the film material a is cut into film sheets to avoid defects such as wrinkles caused by inconsistent deformation of the layers of the film in the length direction during the roller pressing and compounding process.

[0057] Furthermore, the die-cutting assembly 50 has a cutter for cutting the film material a, and the cutter has two blades that are parallel to each other and arranged at intervals, so that a stress release groove is formed between two adjacent film sheets after the film material is cut, further ensuring that the two adjacent film sheets will not be squeezed against each other and wrinkled when they are deformed by rolling and compounding.

[0058] Furthermore, the film material positioning device also includes a waste discharge member 85 arranged on the downstream side of the die-cutting assembly 50, and the waste discharge member 85 is used to discharge the waste material (i.e., the material between two adjacent film sheets) formed by the die-cutting assembly 50 cutting the film material a. More specifically, the waste discharge member 85 has a waste discharge channel, which is connected to the external exhaust device through a pipeline, so that a negative pressure is formed in the waste discharge channel under the action of the external exhaust device, thereby absorbing the waste material on the passing film material. Of course, in another embodiment, the waste discharge channel may be connected to the external exhaust device without a pipeline, but a blowing device may be provided to blow the waste material on the film material a to the waste discharge channel. Optionally, both the waste discharge member 85 and the blowing device may be installed on the base 10.

[0059] Furthermore, the film positioning device further comprises a roller 88 arranged at the downstream side of the die-cutting assembly 50, and the roller 88 is used to support the at least two layers of film a that are wound. The waste discharge member 85 is arranged corresponding to the roller 88 to discharge waste on the film a that is wound around the roller 88.

[0060] See also Figure 1 and Figure 6 As shown, in the embodiment of the present invention, the film positioning device further includes a first adsorption component 60 and a waste collection component (not shown) disposed on the base 10. The first adsorption component 60 is connected to the base 10 so as to be reciprocatingly movable along the conveying direction of the film a. The waste collection component is located at the downstream side of the die cutting component 50. The first adsorption component 60 is used to adsorb and convey a layer of the at least two layers of film a away from the first molding mechanism 20a to the waste collection component, and the waste collection component is used to collect defective film materials.

[0061] Thus, when one of the at least two layers of film material a transported to the positioning assembly and away from the first molding mechanism 20a (i.e., Figure 1 In the embodiment shown, when the top layer of film material is a defective film material segment, the die-cutting assembly 50 cuts off the leading end of the defective film material segment, and then uses the first adsorption assembly 60 to adsorb and transport the defective film material segment to the waste material collection assembly for collection. Then the die-cutting assembly 50 cuts off the tail end of the defective film material segment, and the waste material collection assembly continues to collect the cut defective film material segment.

[0062] Specifically in the embodiment, the film positioning device also includes a second adsorption component 70, which is reciprocally connected to the base 10 along the film a conveying direction. The second adsorption component 70 is used to adsorb and convey a layer of the at least two layers of film a away from the first molding mechanism 20a to the waste collection component. In this way, the first adsorption component 60 and the second adsorption component 70 can cooperate with each other to realize the collection of defective film segments. Specifically, when the layer of the at least two layers of film a conveyed to the positioning component away from the first molding mechanism 20a is a defective film segment, the die-cutting component 50 cuts off the starting end of the defective film segment, and then the first adsorption component 60 is used to adsorb the good film segment behind the defective film segment, and the second adsorption component 70 adsorbs the defective film segment and conveys it to the waste collection component together. Then the second adsorption component 70 releases the defective film segment, and the first adsorption component 60 continues to convey it to the waste collection component, so that the waste collection film collects the defective film segment. Then the die-cutting assembly 50 cuts off the tail end of the defective film material segment, and the waste collection assembly continues to collect the cut defective film material segment.

[0063] It is understandable that both the first adsorption assembly 60 and the second adsorption assembly 70 can adopt the relatively mature vacuum adsorption technology in the prior art, which will not be elaborated here.

[0064] In one embodiment, the waste collection assembly includes a winding roller rotatably arranged around its own axis and a collection plate installed on the base 10. The winding roller is an adsorption roller that can adsorb the film material a and is movably arranged relative to the base 10. When the bad film material segment is transported to the winding roller, the adsorption roller adsorbs the starting end of the bad film material segment, and then reels the bad film material segment onto the winding roller. Then, the winding roller is controlled to move to the collection plate, and the winding roller rotates in the opposite direction to unwind the bad film material segment onto the collection plate (at this time, the adsorption roller is controlled not to adsorb the bad film material segment, so that the bad film material segment can completely fall into the collection plate). Optionally, the winding roller can be a vacuum adsorption roller.

[0065] See also Figure 1 and Figure 7As shown, of course, the waste collection device is not limited to the structure of using a winding roller to reel in the bad film material segment. For example, in another embodiment, the waste collection device includes a fixed pressure roller 81, a dynamic pressure roller 82, a pressure roller driving member 83 and a collection plate 84. The fixed pressure roller 81 is rotatably connected to the base 10 around its own axis. The pressure roller driving member 83 is arranged on the base 10 and is transmission-connected to the fixed pressure roller 81 to drive the fixed pressure roller 81 to rotate around its own axis. The dynamic pressure roller 82 can be connected to the base 10 close to or away from the fixed pressure roller 81 and can rotate around its own axis. The collection plate 84 is installed on the base 10 and is located on the downstream side of the fixed pressure roller 81 and the dynamic pressure roller 82. In this way, when it is necessary to collect the bad film material segment, the dynamic pressure roller 82 moves close to the fixed pressure roller 81 until the starting end of the bad film material segment is pressed against the fixed pressure roller 81. The pressure roller driving member 83 drives the fixed pressure roller 81 to rotate around its own axis, thereby pulling the defective film material segment to the downstream collecting plate 84, thereby completing the collection of the defective film material segment. More specifically, the dynamic pressure roller 82 is arranged on the base 10 through a bracket and is located above the fixed pressure roller 81. The dynamic pressure roller 82 can be driven up and down by a cylinder, thereby abutting against or separating from the fixed pressure roller 81.

[0066] See also Figure 1 and Figure 8 As shown, in an embodiment of the present invention, the film positioning device also includes a guide assembly 90 disposed at the upstream end of the base 10, for guiding at least two layers of film a onto the base 10, and then entering between the first molding mechanism 20a and the second molding mechanism 20b.

[0067] Specifically in the embodiment, the guide assembly 90 includes a guide frame 91 and at least two layers of guide roller mechanisms (not shown). The guide frame 91 is rotatably connected to the upstream end of the base 10. Each layer of the guide roller mechanism includes a guide roller 92, and each guide roller 92 is rotatably connected to the guide frame 91 around its own axis. Each layer of film material a passes through the guide roller 92 of a corresponding layer of the guide roller mechanism and is thus transported downstream. In this way, the guide rollers 92 of each layer of the guide roller mechanism respectively perform preliminary positioning on the corresponding layer of film material a. In addition, the angle of each layer of the guide roller mechanism can be adjusted by controlling the rotation angle of the guide frame 91 relative to the base 10, so that the film material a can be transported more smoothly, which is beneficial to improving the guiding effect.

[0068] It should be noted that the rotation angle of the guide frame 91 can be adjusted by a manual screw adjustment mechanism or an electric adjustment mechanism in the prior art, which is not limited here.

[0069] Furthermore, each layer of the guide roller mechanism also includes an adsorption plate 93, each adsorption plate 93 is connected to the guide frame 91, and the adsorption plate 93 is used to adsorb the corresponding film material and provide tension for the film material to move, so that when the film material passes through the positioning component, the dotting component 40 and the die-cutting component 50, the film material remains flat, not too tight and has a certain degree of freedom, which is conducive to improving the positioning, heating dotting and cutting effects, and improving the stability of the film material positioning device. Preferably, each layer of the guide roller mechanism includes two guide rollers 92, and the adsorption plate 93 is located between the two guide rollers 92. Optionally, the adsorption plate 93 can be a vacuum adsorption plate.

[0070] Based on the above-mentioned film material positioning device, the present invention also provides a film material composite device, including the film material positioning device as described in any of the above embodiments. Specifically, the film material composite device also includes a feeding device and a rolling device. The feeding device is used to unwind at least two layers of film material. The film material positioning device is arranged on the downstream side of the film material feeding device. The rolling device is arranged on the downstream side of the film material positioning device, and is used to roll and composite at least two layers of film material after passing through the film material positioning device.

[0071] When the above-mentioned film material composite equipment is actually in operation, the feeding device unwinds at least two layers of film material to the film material positioning device. The film material positioning device positions and hot-bonds the at least two layers of film material, so that the at least two layers of film material are heat-melted at the hot-bond points and connected to each other, that is, each layer of film material is pre-fixed to prevent misalignment between each film material. Then, the film material positioning device cuts part of the at least two layers of film material after pre-fixation into film sheets, thereby improving the warping, wrinkling and poor lamination caused by the deformation of each layer of film material in the length direction during rolling. Finally, the at least two layers of film material after cutting enter the rolling device for rolling compounding.

[0072] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
