Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 to 5, the present application discloses a welding device, which includes: a welding mechanism 10 for welding the substrates together; a forward pressing mechanism 20 provided upstream of the welding mechanism 10; a back pressure mechanism 40 arranged at the downstream of the welding mechanism 10; the base material comprises a first material 1 and a second material 2, wherein the first material 1 and the second material 2 are overlapped and sequentially enter a front pressing mechanism 20, a welding mechanism 10 and a rear pressing mechanism 40; the front pressing mechanism 20 and the rear pressing mechanism 40 can be tensioned into both ends of the base material of the welding mechanism 10, thereby preventing the position of the first material 1 and the second material 2 from deviating during welding.
The base material may be composed of only the first material 1 and the second material 2 stacked together, or may be composed of a larger number of material layers stacked together.
In addition, when the first material 1 and the second material 2 are overlapped, the two materials can be completely overlapped; for example, when the first material 1 and the second material 2 are equal in width, they cover the surfaces to be bonded to each other; for another example, when the first material 1 and the second material 2 have different widths, the material layer with the narrower width is completely on the other material layer. Alternatively, the first material 1 and the second material 2 may be partially overlapped when they are overlapped; at this time, a part of the material layer is exposed without contacting with another material layer.
In one embodiment, to improve the efficiency of the welding, the material forming the substrate may form a roll of material, which is driven by an unwind reel to effect a sustained release of the substrate. For example, the first material 1 forms a material roll, the material roll is arranged on an unreeling device (not shown), the unreeling device rotates to release the material strip, and then the first material 1 is continuously output, so that the continuous first material 1 can enter the welding device; release of the second material 2 is the same; at this time, the welding device can continuously weld the base material.
In this embodiment, the front pressing mechanism 20 and the rear pressing mechanism 40 always tension the passing substrate, so that the substrate in the welding mechanism 10 is in a stable state. Through setting up preceding pressure mechanism 20 and rear pressure mechanism 40, on the one hand, can guarantee that the substrate is accurate to be walked, on the other hand, can avoid the substrate to produce the displacement.
Of course, in other embodiments, the substrate may be formed by laminating material layers of a specific length. At this time, the base material is equivalent to a material section and has a certain length; the base material is fed to the welding apparatus by a transfer device (not shown, and a mechanism such as a carrying robot, a crown block, or a belt may be used); after the welding is completed, the welded base material is taken out, and the conveying device can convey the base material to be welded at the next section into the welding device.
In this embodiment, since the base material is a material segment, after entering the welding device, the active tape-feeding cannot be realized like the coil material of the previous embodiment; that is, the material section-shaped base material is not moved after entering the welding device, and the welding is directly completed in situ; at this time, the front pressing mechanism 20 and the rear pressing mechanism 40 correspond to a fixing device of the base material, and can "pull" both ends of the base material, which are not required to be welded, so that the portion of the base material, which is required to be welded, stably stays in the welding mechanism 10.
Further, in this embodiment, the front pressing mechanism 20 and the rear pressing mechanism 40 may employ a clamping jaw capable of directly clamping the substrate, thereby defining the position of the substrate. Alternatively, the front pressing mechanism 20 and the rear pressing mechanism 40 may employ suction cups to directly suck the substrate and thereby to define the position of the substrate. Alternatively, the front pressing mechanism 20 and the rear pressing mechanism 40 may be any members that can press against each other, such as a pressing block, a pressing plate, a pressing rod, etc.; after the substrate enters the welding device, the two members constituting the front pressing mechanism 20 or the rear pressing mechanism 40 approach each other to press the substrate therebetween, and can press the substrate, thereby defining the position of the substrate.
If the substrate is to be transported, in one embodiment, the front and/or rear pressing mechanisms 20, 40 comprise: the first pressing roller 21 and the second pressing roller 22 are oppositely arranged, and the base material passes through between the first pressing roller 21 and the second pressing roller 22; and a press roller driving assembly 23 capable of driving the first press roller 21 and the second press roller 22 to move relatively.
Due to the structural characteristics of the compression roller, when the base material walks on the compression roller, the roller of the compression roller can rotate around the roller shaft of the compression roller, and therefore the static bearing surface is prevented from scratching the base material or blocking the base material from walking.
Further, the front pressing mechanism 20 and/or the rear pressing mechanism 40 may further include a roller driving assembly (not shown, a motor may be used), which is connected to at least one of the first pressing roller 21 and the second pressing roller 22 and is capable of driving the connected pressing roller to rotate actively; at this moment, the compression roller can actively rotate, so that the base material passing through the compression roller is driven to move forwards, namely, the compression roller also has a guiding and conveying function. It is easy to understand that, because the first press roller 21 and the second press roller 22 will abut against each other and press the substrate in the actual use process, only one of the press rollers needs to rotate actively to drive the other press roller to follow the rotation.
By providing the pressing roller driving assembly 23, the first pressing roller 21 and the second pressing roller 22 can be moved away from each other during threading, so that the substrate can enter the welding device. And during welding, the press roller driving assembly 23 can drive the first press roller 21 and the second press roller 22 to approach each other and press the base material, so as to control the state of the base material.
The press roller driving assembly 23 may adopt a driving member such as an air cylinder, an electric cylinder, or the like. In one embodiment, one of the first press roller 21 and the second press roller 22 is fixedly arranged, and the other is arranged at the output end of the press roller driving assembly 23; after the threading is finished, the press roller driving component 23 drives one press roller connected with the press roller to move towards the other fixedly arranged press roller so as to clamp the base material. In another embodiment, the pressing roller driving assembly 23 can drive the two pressing rollers to respectively move close to or away from each other; for example, the platen roller driving assembly 23 may include two driving members, one connected to each platen roller.
It should be added that when the front pressing mechanism 20 and the rear pressing mechanism 40 both include the first pressing roller 21 and the second pressing roller 22, in an embodiment, the front pressing mechanism 20 and the rear pressing mechanism 40 may also include a set of pressing roller driving assemblies 23; at this time, the two sets of platen driving assemblies 23 can drive the corresponding set of platen to operate. In still another embodiment, the first pressing roller 21 and the second pressing roller 22 of the front pressing mechanism 20, and the first pressing roller 21 and the second pressing roller 22 of the rear pressing mechanism 40 may be provided on the same set of pressing roller driving assemblies 23; with particular reference to fig. 1; because the threading is that the base materials are pulled through the welding device in sequence manually or mechanically, the front pressing mechanism 20 and the rear pressing mechanism 40 can be opened and the base materials can pass through conveniently before threading only by arranging one group of pressing roller driving assemblies 23; it is also possible to "close" the forward and rearward pressing mechanisms 20, 40 prior to welding, to facilitate tensioning of the substrate.
It should be noted that the front pressing mechanism 20 and the rear pressing mechanism 40 may have the same structure or different structures, as long as the substrates on both sides of the welding mechanism can be tensioned, and the present application is not limited specifically.
With continued reference to FIG. 1, the first direction is the substrate's direction of travel, i.e., the left and right direction as shown; the second direction is the width direction of the base material, i.e., the front-back direction perpendicular to the paper surface in the figure; the third direction is the thickness direction of the base material, i.e., the vertical direction in the figure. In the figure, when the first press roller 21 and the second press roller 22 press the substrate, the first press roller 21 is under and supports the substrate; at this time, the first press roller 21 of the front press mechanism 20 and the surface thereof supporting the substrate are at the same level as the first press roller 21 of the rear press mechanism 40 and the surface thereof supporting the substrate, that is, the substrate "gripped" by the front press mechanism 20 and the rear press mechanism 40 is in a horizontal state. When the part to be welded of the base material is in a horizontal state, the states of all material layers forming the base material are stable and are not easy to deviate in the horizontal direction; further, the substrate is "pinched" in the vertical direction by the first press roller 21 and the second press roller 22, and is "pinched" in the vertical direction (the left-right direction) by the front press mechanism 20 and the rear press mechanism 40, so that the substrate can be stably stacked and the relative displacement is less likely to occur.
With further reference to fig. 1, the welder mechanism 10 is used to weld the working end of the substrate, also at the same height as the first press roller 21 supporting the surface of the substrate; at this point, the substrate is being fed from left to right, the front and rear pressing mechanisms 20 and 40 always "clamp" the substrate, and the welder mechanism 10 can continue to weld the substrate efficiently.
The base material is formed by laminating a plurality of material layers; it can be seen that the thickness of each material layer is not guaranteed to be completely consistent during manufacturing, and there are always concave or convex portions. The uneven thickness may interfere with the control of the first press roller 21 and the second press roller 22 on the base material; for example, when the surface of the substrate is raised to a certain extent, the substrate may be jammed between the first pressing roller 21 and the second pressing roller 22 which are oppositely arranged, so that the substrate cannot be continuously fed; for another example, when the surface of the substrate is excessively concave, the first press roller 21 and the second press roller 22 may not press the substrate, so that the substrate state cannot be ensured.
For this purpose, the welding device further comprises a mounting frame 30, and the first pressing roller 21 and/or the second pressing roller 22 are movably arranged on the mounting frame 30; an elastic part 4 is arranged between the first pressing roller 21 and the mounting frame 30; and/or an elastic member 4 is arranged between the second pressing roller 22 and the mounting frame 30; when the thickness of the substrate passing through the first press roller 21 and the second press roller 22 is changed, the elastic member 4 can be deformed to ensure that the first press roller 21 and the second press roller 22 always press the substrate.
Specifically, the thickness direction of the base material is the third direction. At this time, a matched set of the first pressing roller 21 and the second pressing roller 22 is oppositely arranged along the third direction; at least one of the first pressing roller 21 and the second pressing roller 22 is movable in a third direction on the mounting frame 30; the elastic member 4 can be compressed or extended in the third direction to compensate for the action of the first pressing roller 21.
In one embodiment, referring to fig. 1, 4 and 5, the third direction is a vertical direction; the first pressing roller 21 is relatively fixedly arranged on the mounting frame 30; the second press roller 22 is movable in a third direction. At this time, the mounting frame 30 includes a bottom plate 35, a guide 36 extending in the vertical direction is provided on the bottom plate 35, and the first pressing roller 21 is slidably provided on the guide 36 and can move in the vertical direction along the guide 36; meanwhile, an elastic piece 4 arranged along the vertical direction is arranged between the first pressing roller 21 and the bottom plate 35; when the first press roller 21 and the second press roller 22 are pressed against each other, the elastic member 4 is always in a compressed state. When the first pressing roller 21 moves upward along the guide 36, the elastic member 4 is gradually restored; the elastic member 4 is gradually compressed as the first pressing roller 21 moves down along the guide 36. For example, when the surface of the base material is convex, the first press roller 21 can move downwards to avoid the convex; at this time, the elastic member 4 is compressed and tends to return to its original shape, and the elastic restoring force generated by the elastic member acts on the first pressing roller 21 so that the first pressing roller 21 can also press the base material. Similarly, when the surface of the base material is concave, the first press roller 21 can move upwards to compensate the concave; at this time, the elastic member 4 is slightly released by the depression to facilitate the upward movement of the first pressing roller 21; meanwhile, since the elastic member 4 is still in a compressed state, it has a tendency to recover to its original state, and the elastic restoring force generated by it acts on the first pressing roller 21, so that the first pressing roller 21 can press the substrate.
The guide 36 may be a guide rod, a guide rail, a guide groove, or other guide members. The elastic member 4 may be a spring.
In other embodiments, the third direction may vary according to the specific orientation of the substrate. In addition, the second pressing roller 22 may be relatively fixedly disposed on the mounting frame 30, and the first pressing roller 21 may move in the third direction; it is also possible that both the first press roller 21 and the second press roller 22 are movable in the third direction.
In order to improve the applicability of the device, the first press roller 21 and the second press roller 22 are arranged on the mounting frame 30, and the positions of the first press roller and the second press roller can be adjusted along the second direction; the second direction is the width direction of the substrate.
For example, referring to fig. 1, the base material is transported in the left-right direction, and the width direction thereof is the front-back direction perpendicular to the drawing sheet. By adjusting the positions of the first pressing roller 21 and the second pressing roller 22 in the second direction, the position of the pressing roller when pressed against the surface of the substrate can be adjusted.
It should be explained that the welding mechanism 10 is mainly used to weld together the overlapped portions of the material layers; therefore, when the front pressing mechanism 20 and the rear pressing mechanism 40 tension the substrate, it is necessary to ensure that the portions where the material layers are laminated are controlled. For example, referring to fig. 6 and 7, the width of the first material 1 is smaller than the width of the second material 2, and when the base material is formed by laminating the first material 1 on the left side of the upper surface of the second material 2. At this time, the welding mechanism 10 is mainly applied to the surface of the first material 1 to ensure that the first material 1 is completely bonded to the upper surface of the second material 2. At this time, the first pressing roller 21 and the second pressing roller 22 are adjusted to correspond to the first material 1 and to be positioned at the left side of the second material 2, so that the first pressing roller 21 and the second pressing roller 22 can press the first material 1 against the second material 2.
In one embodiment, two sets of first adjusting mechanisms are further disposed on the mounting frame 30 corresponding to the front pressing mechanism 20 or the rear pressing mechanism 40, and are respectively connected to the first pressing roller 21 and the second pressing roller 22; the first adjustment mechanism includes: a first guide extending in the second direction, on which the first press roller 21 or the second press roller 22 is slidably disposed; and the first adjusting piece is connected with the corresponding first pressing roller 21 or second pressing roller 22 and can drive the corresponding pressing roller to move along the first guide piece. The first guide part can adopt guide members such as a guide rod, a guide rail, a guide groove and the like; the first adjusting piece can adopt adjusting components such as an air cylinder, a manual adjusting rod, a drive plate, a micrometer and the like. According to the position of the overlapped part of the base material, the first adjusting piece can adjust the corresponding press roller to be opposite to the overlapped part, so that the overlapped part of the base material is pressed when the first press roller 21 and the second press roller 22 are abutted. Of course, when the front pressing mechanism 20 and the rear pressing mechanism 40 both have the first pressing roller 21 and the second pressing roller 22, four sets of first adjusting mechanisms are provided on the mounting frame 30 so as to meet the adjustment requirement.
In another embodiment, the first pressing roller 21 and the mounting frame 30 are provided with a first kidney-shaped hole 31 and a first threaded hole 32 which can be matched with each other; the second press roller 22 and the mounting rack 30 are also provided with a first kidney-shaped hole 31 and a first threaded hole 32 which can be matched with each other; the first kidney holes 31 extend in the second direction.
Referring to fig. 2 and 4 in particular, the mounting bracket 30 includes a bottom plate 35 and a top plate 37, one of the first pressing roller 21 and the bottom plate 35 is provided with a first kidney-shaped hole 31, and the other one is provided with a plurality of first threaded holes 32 arranged at intervals along the second direction; the position of the first pressing roller 21 in the second direction can be manually adjusted by loosening the first kidney-shaped hole 31 and the first threaded hole 32; the first threaded hole 32 is always exposed in the first kidney-shaped hole 31, and the position of the first press roller 21 can be fixed by locking the first kidney-shaped hole 31 and the first threaded hole 32 with screws after the first kidney-shaped hole 31 is adjusted to a proper position. Similarly, one of the second pressing roller 22 and the top plate 37 is provided with a first kidney-shaped hole 31, and the other one is provided with a plurality of first threaded holes 32 arranged at intervals along the second direction; details are not repeated.
In addition, in order to improve the applicability of the device, the first press roller 21 and the second press roller 22 are arranged on the mounting frame 30, and the positions of the first press roller and the second press roller can be adjusted along the third direction; the third direction is perpendicular to the surface of the substrate.
For example, referring to fig. 1, the base material is walked in the left-right direction, and the third direction is a vertical direction. Through adjusting the position of first compression roller 21 and second compression roller 22 in the third direction, can correspond according to the height of substrate tape transport, adjust first compression roller 21 and second compression roller 22, guarantee that first compression roller 21 and second compression roller 22 accurately compress the substrate all the time.
In one embodiment, two sets of second adjusting mechanisms are further disposed on the mounting frame 30 corresponding to the front pressing mechanism 20 or the rear pressing mechanism 40, and are respectively connected to the first pressing roller 21 and the second pressing roller 22; it includes: a second guide extending in the third direction, on which the first pressing roller 21 or the second pressing roller 22 is slidably disposed; and the second adjusting part is connected with the first pressing roller 21 or the second pressing roller 22 and can drive the first pressing roller 21 or the second pressing roller 22 to move along the second guide part. The second guide part can adopt guide members such as a guide rod, a guide rail, a guide groove and the like; the second adjusting piece can adopt adjusting components such as an air cylinder, a manual adjusting rod, a drive plate, a micrometer and the like. According to the height that the substrate was walked, the second adjusting part can adjust the compression roller that corresponds to its high position that can accurately support to press or accept the substrate to when first compression roller 21 and second compression roller 22 offset, the accurate substrate that compresses tightly can not drive the substrate skew and predetermine the height. Of course, when the front pressing mechanism 20 and the rear pressing mechanism 40 both have the first pressing roller 21 and the second pressing roller 22, four sets of second adjusting mechanisms are provided on the mounting frame 30 so as to meet the adjustment requirement.
In another embodiment, the first pressing roller 21 and the mounting frame 30 are provided with a second kidney-shaped hole 33 and a second threaded hole 34 which can be matched with each other; the second press roller 22 and the mounting rack 30 are also provided with a second kidney-shaped hole 33 and a second threaded hole 34 which can be matched with each other; the second kidney-shaped hole 33 extends in the third direction.
With particular reference to fig. 3 and 5, the mounting bracket 30 includes a bottom plate 35 having a first side plate 38 thereon and a top plate 37 having a second side plate 39 thereon; one of the first pressing roller 21 and the first side plate 38 is provided with a second kidney-shaped hole 33, and the other one is provided with a plurality of second threaded holes 34 which are arranged at intervals along the third direction; the position of the first pressing roller 21 in the third direction can be manually adjusted by loosening the second kidney-shaped hole 33 and the second threaded hole 34; the second threaded hole 34 is always exposed in the second kidney-shaped hole 33, and the position of the first pressing roller 21 can be fixed by locking the second kidney-shaped hole 33 and the second threaded hole 34 with screws after the second kidney-shaped hole 33 is adjusted to a proper position. Similarly, one of the second pressing roller 22 and the second side plate 39 is provided with a second kidney-shaped hole 33, and the other one is provided with a plurality of second threaded holes 34 arranged at intervals along the third direction; details are not repeated.
It should be explained that, when the positions of the front pressing mechanism 20 and the rear pressing mechanism 40 are adjusted in the third direction, the positions of the first pressing roller 21 and the second pressing roller 22 need to be adjusted synchronously; for example, when the third direction is a vertical direction, one of the pressing rollers moves upward, and the other pressing roller also needs to move upward to ensure that the two pressing rollers can accurately offset each other. Of course, when the pressing roller driving assembly 23 is matched, the position of one of the pressing rollers in the vertical direction may be adjusted, and the other pressing roller is driven to be in place by the pressing roller driving assembly 23, so that the pressing roller driving assembly and the pressing roller driving assembly are finally abutted.
Further, as mentioned above, the "welding mechanism 10 is mainly used for welding the overlapped portions of the material layers together; therefore, when the front pressing mechanism 20 and the rear pressing mechanism 40 tension the substrate, it is necessary to ensure that the overlapped portions of the material layers are controlled ", that is, when the first pressing roller 21 and the second pressing roller 22 are used in the front pressing mechanism 20 and/or the rear pressing mechanism 40, the axial length of the roller of the first pressing roller 21 and the second pressing roller 22 is not shorter than the width of the overlapped portion of the substrate.
For example, when the base material shown in fig. 4 is welded, since the width of the first material 1 is smaller than that of the second material 2, the first material 1 is completely located on the upper surface of the second material 2 when the base material is overlapped. At this time, the roller axial length of the first pressing roller 21 and the second pressing roller 22 is not shorter than the width of the first material 1; when the first pressing roller 21 and the second pressing roller 22 abut against each other and clamp the base material, the first pressing roller 21 and the second pressing roller 22 can at least press the first material 1 onto the second material 2.
Also for example, the substrate further comprises a third material 3, the third material 3 being at least partially laminated with the first material 1 and the second material 2. Referring to fig. 8 and 9, the width of the first material 1 is smaller than the width of the second material 2, and when overlapped, the first material 1 is completely positioned at the left side of the upper surface of the second material 2; the right side of the third material 3 is overlapped on the lower surface of the second material 2, the overlapped part covers the overlapped part of the first material 1 and the second material 2, and in addition, the left side part of the third material 3 is exposed and is not overlapped with other material layers. At this time, the axial length of the first press roller 21 and the second press roller 22 is not shorter than the width of the first material 1, and when the first press roller 21 and the second press roller 22 press the base material, the overlapped part of the material layers of the base material can be pressed, so that the overlapped part can not be displaced in the welding process.
Of course, the substrate may also consist of further material layers, which may be completely superimposed on each other or partially superimposed, as long as it is ensured that the first pressure roller 21 and the second pressure roller 22 are able to press the parts of them superimposed together.
Additionally, in one embodiment, the welding mechanism 10 includes a sonotrode; the width of the wheel surface of the ultrasonic welding wheel is consistent with the width of the overlapped part of the base materials, so that the ultrasonic welding wheel can weld the overlapped part of the base materials together.
Specifically, the welding mechanism 10 adopts ultrasonic welding, and during welding, an ultrasonic welding wheel is pressed against the base material; because of the ultrasonic characteristic, the ultrasonic welding wheel can continuously shake axially, and the overlapped parts of the base materials which are pressed against each other rub each other through high-frequency vibration waves, generate high temperature and finally perform hot melt bonding. As will be readily appreciated, the sonotrode will vibrate due to the sound waves, and therefore the material layers pressed against by the sonotrode will also vibrate in the direction of their width, which is liable to cause relative displacements between the material layers. At this time, the substrate can be well controlled by the front pressing mechanism 20 and the rear pressing mechanism 40, and the material layers can be prevented from being relatively displaced.
Further, the closer the front pressing mechanism 20 and the rear pressing mechanism 40 are to the welding mechanism 10, the better the tensioning effect on the base material in the welding mechanism 10 is.
As can be easily understood, the welding mechanism 10 is mainly used to weld the overlapped portions of the material layers together, so that the width of the wheel surface of the sonotrode against the substrate is the same as the width of the overlapped portion of the substrate, and the sonotrode can be ensured to weld only the overlapped portion of the substrate, thereby preventing the sonotrode from affecting the substrates of other portions.
For example, when the base material shown in fig. 8 is welded, the width of the wheel face of the sonotrode wheel may be the same as the width of the first material 1, and when welding, the sonotrode wheel directly abuts against the first material 1, and finally, the welding of the first material 1, the second material 2 and the third material 3 is realized.
It should be explained that, unlike the sonotrode, when the front and/or rear pressing mechanisms 20, 40 employ the first and second rollers 21, 22, the axial length of the rollers 21, 22 may be longer than the width of the overlapped portion of the substrate, for example, the axial length of the rollers 21, 22 may cover the width of the substrate; when welding the base material shown in fig. 8, the pressing roller may press the first material 1, the second material 2, and the third material 3 completely, and is not limited to pressing only the overlapped portions.
Further, the welding mechanism 10 may include two sonotrodes, similar to a set of first pressing roller 21 and second pressing roller 22, which are used together, and the two sonotrodes are also arranged oppositely along the thickness direction of the substrate, and can "clamp" the substrate, so as to weld the two sides of the substrate, thereby accelerating the welding efficiency. Wherein the sonotrode wheel may be arranged on the pressure roller drive assembly 23; driven by the roller drive assembly 23, the two sonotrodes can be moved closer together to "pinch" the substrate, as with the first roller 21 or the second roller 22, or away from each other to facilitate threading of the substrate.
Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. Such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
