Description

[0002] In the process of processing the material tape, in order to save the time of the next material tape passing through the equipment after the processing of the previous material tape is completed, the next material tape is usually spliced at the tail end of the previous material tape, so as to realize continuous processing. In order to ensure the quality of the splicing, a part of the tail end of the previous material tape and the head end of the next material tape are cut off, and then welding is performed at the cut part. In the related art, a cutter is usually used for physical cutting. With the increase of the use time, the cutter will be worn out, resulting in burrs at the cut part, which affects the quality of the splicing. SUMMARY

In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0068] As Figure 1As shown, when it is necessary to connect two strips of material 500 together, it is necessary to first separate the end portion 510 of the material 500 from the main body portion 520 of the material along the illustrated cutting seam 530, so as to form a flat cutting surface, and then butt joint the cutting surfaces of the two strips of material 500 together and weld them, so as to form a continuous strip of material 500. In the related art, the end portion 510 is usually physically cut off by a cutter, and as the use time increases, the cutter will be worn, thereby causing burrs to remain on the cutting surface, which affects the subsequent welding quality. Based on the above problems, the present application proposes a laser strip joining device which cuts the material layer by layer by laser to ensure the cutting quality, and simultaneously bends the end portion 510 by the bending device 300 to avoid fusion on both sides of the cutting seam. The following will be specifically described in combination with the drawings.

[0069] With reference to Figure 2 , Figure 3 The laser strip joining device comprises a rack 100, two positioning devices 200, a bending device 300 and a laser device 400. The rack 100 serves as the main bearing structure, and the positioning device 200, the bending device 300 and the laser device 400 are all connected with the rack 100. In some embodiments, the laser strip joining device can further comprise a power supply which is not shown. The power supply can provide energy for the positioning device 200, the bending device 300 and the laser device 400, so that the laser strip joining device is not limited by an external power supply, thereby being able to be flexibly moved between different processing devices to perform strip joining operations on the material strips on different devices. Compared with the scheme in which a fixed strip joining module is arranged on each processing device, the present embodiment can meet the strip joining requirements of multiple processing devices by one laser strip joining device, which is helpful to reduce the cost. In order to adapt to the movement of the laser strip joining device, the bottom of the rack 100 is further provided with a pulley. In the illustrated embodiment, the positioning device 200, the bending device 300 and the laser device 400 are all connected to the upper part of the rack 100, which is convenient for the operator to perform the strip joining operation. The lower part of the rack 100 has a mounting cavity in which the aforementioned power supply is mounted.

[0070] With reference to Figure 4 , and with reference to Figure 2 and Figure 3 The positioning device 200 is used to position the material strip 500, so that the offsets of the two main body portions 520 in the thickness direction, the width direction and the length direction all meet the requirements, thereby enabling the cutting surfaces of the two main body portions 520 to be accurately butt jointed together. The laser strip joining device comprises two positioning devices 200 which are used to position the two strips of material 500 respectively, and the two positioning devices 200 are sequentially arranged along the length direction of the material strip 500.

[0071] The two positioning devices 200 can also drive the two material belts 500 to move closer or further apart along their length. In the illustrated embodiment, both positioning devices 200 can move along their length, and they can move synchronously and independently. In the initial state, the positioning devices 200 are respectively located at... Figure 4 At the left and right ends, when a single positioning device 200 is in Figure 4 When the working position is reached, the material strip 500 can be cut by the laser device 400. When both positioning devices 200 are in the working position... Figure 4 When the working position is shown, two strips 500 can be welded.

[0072] In this embodiment, the laser device 400 can cut the strip 500 sequentially along its thickness direction. That is, the depth of each cut in this embodiment is less than the thickness of the strip 500. It should be noted that this embodiment uses laser cutting of the strip 500, which, compared to cutting the strip 500 with a cutting tool, eliminates the problem of wear and tear, thus preventing burrs caused by wear. Simultaneously, because the amount cut in a single pass is smaller, the cutting quality is improved, ensuring a smooth cut surface. In short, the laser splicing device of this embodiment can form a smooth cut surface, facilitating high-quality splicing. Furthermore, sequential cutting also reduces the power requirements of the laser device 400, lowering equipment costs. It should be noted that the number of cuts by the laser device 400 is adjusted according to the thickness of the strip 500; generally, thicker strips 500 require more cuts.

[0073] During the laser cutting process, the areas on both sides of the kerf 530 may melt. Because the kerf 530 is very narrow and the depth of a single cut is relatively small, the areas on both sides of the kerf 530 may re-fuse after the laser passes, creating an adhesive area that affects subsequent cutting and joining. Based on this, referring to... Figure 5 , Figure 6 This embodiment also includes a bending device 300. When cutting a strip of material 500, the bending device 300 can drive the end 510 of the strip 500 to bend, thereby keeping the two sides of the cut 530 separate and preventing them from merging again. Specifically, after each cut by the laser device 400, the bending device 300 drives the end 510 of the strip 500 to bend at a set angle along the cutting direction, referring to... Figure 5 When the depth of the slit 530 is shallow, the bending angle of the end 510 is relatively small. When the depth of the slit 530 increases, the bending angle of the end 510 also increases relatively.

[0074] It should be noted that the bending angle of the end 510 can be the same or different each time the bending device 300 is driven.

[0075] The bending assembly 310 can move relative to the rack 100 between a first position and a second position, when the bending assembly 310 is in the first position, the end portion 510 of the material belt 500 can be bent, when the bending assembly 310 is in the second position, the positioning device 200 can be avoided, and the butt joint of the main body portion 520 after cutting is facilitated. In the illustrated embodiment, the bending device 300 and the positioning device 200 can move in the horizontal direction, specifically, the two positioning devices 200 move along the length direction of the material belt 500, and the bending device 300 is arranged on one side of the positioning device 200 and can move along the width direction of the material belt 500.

[0076] Based on the above structure, the main working process of the laser belt connecting device is as follows:

[0077] 1. In the initial state, the two positioning devices 200 are located at the feeding position far away from each other, and the bending device 300 is located at the second position, then the material belt 500 is fixed on the positioning device 200, the end portion 510 of the material belt 500 extends from the positioning device 200 and towards the positioning device 200 on the opposite side;

[0078] 2. The first positioning device 200 drives the first material belt 500 to move to the working position (for example, the position in Figure 4 , Figure 6 ), and the bending device 300 moves from the second position to the first position (for example, the position shown in Figure 6 ), at this time, the end portion 510 extending from the positioning device 200 is arranged in the bending device 300, and the part of the material belt 500 exposed between the bending device 300 and the positioning device 200 is the cutting position, the laser device 400 cuts the end portion 510 from the position, then the positioning device 200 and the bending device 300 are reset, the second positioning device 200 drives the second material belt 500 to move to the working position (for example, the position in Figure 4 , Figure 6 ), and the bending device 300 moves from the second position to the first position again, and the above process is repeated until the second material belt 500 is cut, and the positioning device 200 and the bending device 300 are reset.

[0079] 3. The two positioning devices 200 move to the working position again, so that the two material belts 500 are butt jointed, and then the two material belts 500 are welded to complete the belt connection.

[0080] It should be noted that the above process has other embodiments, for example, when a single strip 500 needs to be cut, the bending device 300 can first move from the second position to the first position, and then the positioning device 200 drives the strip 500 to move to the working position, so that the end portion 510 extending from the positioning device 200 is arranged in the bending device 300. For another example, when the second strip 500 is cut, the second positioning device 200 can remain at the current position, and the first positioning device 200 moves to the working position again, which can also realize the butt joint of the two strips 500.

[0081] When the main body portions 520 of the two strips 500 are butt jointed, the two strips need to be fixed by welding. In other embodiments, the laser device 400 can be used for cutting and welding the strip, that is, the laser device 400 of the embodiment has cutting and welding functions, so that a separate welding device is not needed, the cost can be reduced, and the switching time of the laser device 400 and the welding device can be saved, thereby improving the efficiency of the strip butt joint. The parameters of the laser device 400 can be adjusted to meet different parameter requirements in cutting and welding. It should be noted that in other alternative embodiments, the laser strip butt joint device can also be provided with a separate welding device.

[0082] Specifically, the laser device 400 includes a laser light source and a laser galvanometer which are not shown. The laser light source is used to form a laser beam, and the laser galvanometer is connected with the laser light source and is used to move the laser beam along the width direction of the strip 500, so that the laser beam can move along the cutting surface of the main body portion 520 to realize the welding of the strip. In the embodiment, the laser device 400 does not need to move, which is helpful to simplify the structure. In other alternative embodiments, the laser device 400 includes a laser light source and a third driving assembly which are not shown. The laser light source is used to form a laser beam, and the third driving assembly is connected with the laser light source and can drive the laser light source to move along the width direction of the strip 500, so that the laser beam can move along the cutting surface of the main body portion 520 to realize the welding of the strip. The third driving device can be a driving system composed of a servo motor and a lead screw, or an electric cylinder and the like to ensure the accuracy of movement.

[0083] In other embodiments, when the laser device 400 cuts to a certain depth, the bending device 300 can drive the end portion 510 to reciprocate along the cutting direction and the reverse direction of the cutting direction, so that the end portion 510 is separated from the main body portion 520. Figure 5As shown, when the laser cuts the material strip 500 from above, the cutting direction is downward, and the reverse direction of the cutting direction is upward. The bending device 300 drives the end portion 510 to reciprocate up and down, and finally breaks the end portion 510. It should be noted that the material strip 500 used in the embodiment has a certain rigidity. When the laser cuts to a certain depth, the end face formed by breaking in the above manner not only has good flatness, but also can avoid the residual adhesion between the end portion 510 and the main body portion 520 (as described above, laser cutting can cause the material strip to melt. If the material strip 500 is completely cut by laser, there is a possibility that the melted part is bonded. After the adhesion part is broken again, burrs will be formed, which will affect the butt joint quality). In addition, the time of laser cutting can be reduced, the service life of the laser device 400 can be prolonged, and the energy consumption can be reduced. Generally, after the cutting depth exceeds half of the thickness of the material strip 500, the end portion 510 and the main body portion 520 can be separated by breaking.

[0084] In other embodiments, after the end portion 510 and the main body portion 520 are separated, the laser device 400 further cuts along the cutting surface once or more to further remove the burrs of the cutting surface and ensure the flatness of the cutting surface. Specifically, the laser device 400 includes a laser light source for forming a laser beam and a laser galvanometer connected with the laser light source, for moving the laser beam along the width direction of the material strip 500, so that the laser beam can move along the cutting surface of the main body portion to remove the burrs of the separation part. In the embodiment, the laser device 400 does not need to move, which helps to simplify the structure. In other alternative embodiments, the laser device 400 includes a laser light source for forming a laser beam and a third driving assembly connected with the laser light source, which can drive the laser light source to move along the width direction of the material strip 500, so that the laser beam can move along the cutting surface to remove the burrs of the separation part. The third driving device can be a driving system composed of a servo motor and a lead screw, or an electric cylinder to ensure the accuracy of movement.

[0085] In some embodiments, referring to Figure 6 and with reference to Figures 7 to 9 The bending device 300 includes a bending assembly 310, a first driving assembly 320, and a second driving assembly not shown. The bending assembly 310 directly contacts the end portion 510 of the material strip 500 and can drive the end portion 510 to bend. The first driving assembly 320 and the second driving assembly respectively drive the bending assembly 310 to move correspondingly.

[0086] Referring to Figures 7 to 9In the illustrated embodiment, the bending assembly 310 includes two clamping portions 311, with a gap 312 between them. When the end portion 510 passes through the gap 312, the two clamping portions 311 can cause the end portion 510 to bend. As shown in the figure, the gap 312 is open on both sides in the left-right direction (i.e., the length direction of the strip) and open on one side in the front-back direction (i.e., the width direction of the strip). When the bending assembly 310 moves from the second position to the first position (e.g., from front to back), the end portion 510 of the strip 500 can enter the gap 312 from the far ends of the two clamping portions 311 (e.g., the rear end in the figure). When the bending assembly 310 moves from the first position to the second position (e.g., from back to front), the end portion 510 of the strip 500 can exit the gap 312 from the far ends of the two clamping portions 311 (e.g., the rear end in the figure). It should be noted that the end 510 of the material strip can also enter or exit the gap 312 along the length direction of the material strip 500 (e.g., the left and right direction in the figure).

[0087] The bending assembly 310 may also include a rotating shaft 313, with the clamping part 311 connected to the rotating shaft 313 and capable of rotating synchronously with the rotating shaft 313. The axis of the rotating shaft 313 is arranged parallel to the horizontal plane.

[0088] Reference Figure 6 In the illustrated embodiment, the first driving component 320 is connected to the bending component 310, specifically to the rotating shaft 313, and is used to drive the bending component 310 to rotate around the horizontal axis. It should be noted that when the bending component 310 bends the end 510, the first driving component 320 drives the bending component 310 to rotate gradually at a small angle. Furthermore, when the bending component 310 separates from the material belt 500, the first driving component 320 can still drive the bending component 310 to rotate continuously by 180°. Figure 7 , Figure 9 As shown, the bending assembly 310 includes a clamping part 311 and a rotating shaft 313. The clamping part 311 is offset from the rotating shaft 313. The bending assembly 310 can rotate about a horizontal axis to cooperate with the positioning devices 200 on both sides respectively. Specifically, when the bending assembly 310 is in the position of Figure 9 In the state shown, the clamping part 311 is located on the right side, so that it can cooperate with the positioning device 200 on the left side to cut the left strip 500. After the left strip 500 is cut, the bending component 310 rotates 180° to the left side, so that it can cooperate with the positioning device 200 on the right side to cut the right strip 500. In this way, the laser device 400 does not need to move along the length of the strip 500 to cut the strips 500 on both sides at the same position, which facilitates the subsequent docking of the two strips 500.

[0089] The second driving assembly is connected with the first driving assembly 320, which can drive the first driving assembly 320 to move between the first position and the second position synchronously with the bending assembly 310. The first driving assembly can be a rotary motor, and the second driving assembly can be a driving system composed of a motor and a screw rod.

[0090] With reference to Figures 7 to 9 The bending assembly of the embodiment is suitable for bending the light material belt, that is, there is no other component on the material belt 500, and the thickness of the material belt 500 is very thin, so the gap 312 of the bending assembly 310 is relatively small, and the rotation radius during rotation is small, so the rotary mode can be used to bend the end portion 510.

[0091] In order to facilitate the material belt 500 to enter the gap 312, with reference to FIG. 7, Figure 8 The end surface of the at least one clamping portion 311 includes a guide surface 3111 in the direction from the second position to the first position, that is, even if the end portion 510 is offset in the up-down direction, the guide surface 3111 can guide the end portion 510 into the gap 312 in the direction from the first position to the second position, and the accuracy requirement of the alignment is reduced. The guide surface 3111 can be a continuous arc surface to avoid damaging the material belt 500 when in contact.

[0092] In another embodiment of the bending assembly 310, with reference to Figure 10 The same as the above-mentioned embodiment, the difference between the embodiment and the above-mentioned embodiment is that: the material belt 500 applied in the embodiment also includes functional devices such as protection feet, which results in that the overall thickness of the material belt 500 is relatively thick, and correspondingly, the width of the gap 312 is relatively wide. If the bending assembly 310 still drives the end portion 510 to bend through the rotary mode, there will be a problem of excessively large rotation radius, which results in that a relatively large relative movement occurs between the clamping portion 311 and the end portion 510, and the positioning effect is affected. Based on this, the bending assembly 310 in the embodiment drives the end portion 510 to bend through the up-down movement mode, and with reference to Figure 11 The bending device 300 includes the bending assembly 310, the first driving assembly 320, and the second driving assembly 330, wherein the second driving assembly 330 is the same as the above-mentioned embodiment, which can drive the bending assembly 310 to move between the first position and the second position. Different from the first embodiment, the first driving assembly 320 of the embodiment can drive the bending assembly 310 to move in the vertical direction, so as to drive the end portion 510 to bend, wherein the single movement distance of the bending assembly 310 is small, so as to drive the end portion 510 to bend by a small angle, so as to adapt to the multiple cutting of the laser device 400.

[0093] In the embodiment, the first driving assembly 320 comprises a servo motor and a screw rod arranged in the vertical direction, so as to accurately control the distance of the bending assembly 310 moving in the up-down direction. The second driving assembly 330 comprises a servo motor and a screw rod arranged in the horizontal direction, so as to accurately control the distance of the bending assembly 310 moving in the horizontal direction.

[0094] In some further embodiments, the bending assembly 310 can also rotate around the horizontal axis, and the clamping part 311 is offset from the rotation axis, so that the bending assembly 310 can be rotated by 180° to cooperate with the positioning devices 200 on both sides, as shown in FIG. 6. Figure 11 The first driving assembly 320 can not only drive the bending assembly 310 to rotate in the vertical direction, but also drive the bending assembly 310 to rotate around the horizontal axis, so the first driving assembly 320 further comprises a rotary motor, the bending assembly is connected to the driving end of the rotary motor, and the rotary motor is connected to the screw rod through the screw rod seat. It should be noted that the rotary motor can not only drive the bending assembly 310 to rotate by 180° to match the positioning devices 200 on both sides, but also drive the bending assembly 310 to rotate to the inclined state after the end part 510 is separated from the main body part 520, so that the cut end part 510 is separated from the bending assembly 310.

[0095] Referring to FIG. 6, Figure 4 and Figure 6 The positioning device 200 comprises a positioning assembly 210 and a fourth driving assembly 220. The positioning assembly 210 is used for positioning the material belt 500, and the fourth driving assembly 220 is connected to the positioning assembly 210 and is used for driving the positioning assembly 210 to move along the length direction of the material belt 500. In the embodiment, the fourth driving assembly 220 can be a linear motor, which can well guarantee the accuracy in the length direction, so that the cut surfaces of the two main body parts 520 can be accurately butted.

[0096] Under the driving of the corresponding fourth driving assembly 220, the two positioning devices 200 can move independently or synchronously, specifically including: a single positioning assembly 210 moving away from the opposite positioning assembly 210, so as to drive the cut material belt 500 to reset to the initial position; a single positioning assembly 210 moving towards the opposite positioning assembly 210, and combining the movement of the bending assembly 310, so that the end part 510 positioned by the positioning assembly 210 is arranged in the gap 312 of the bending assembly 310; and the two positioning assemblies 210 can also move synchronously towards each other, so as to butt the two main body parts 520 after cutting. It should be noted that in the embodiment, the positioning assembly 210 of the embodiment is reset to the initial position after the material belt 500 is cut, and then moves synchronously towards each other based on the initial position, so as to guarantee the butt accuracy.

[0097] In some embodiments, referring to FIG. 6, Figure 12 ,Figure 13 In order to realize the positioning of the material belt in the vertical direction, the positioning assembly 210 comprises a base 211, a cover plate 216, a pressing plate 217, a threaded fastener 218 and an elastic member not shown. The top of the base 211 is provided with a positioning surface 2111 arranged horizontally for carrying the material belt 500. The cover plate 216 is connected to the base 211 and can move relative to the base 211 so as to switch between the loading state and the positioning state. In the loading state, the operator can load the material belt 500 onto the base 211 or remove the material belt 500 from the base 211. In the illustrated embodiment, the cover plate 216 is rotatably connected to the base 211 so as to be conveniently opened and closed. Of course, the cover plate 216 can also be connected to the top of the base 211 through a guide column or the like and switched between the loading state and the positioning state through up and down movement.

[0098] The pressing plate 217 is connected to the side of the cover plate 216 facing the base 211. The pressing plate 217 can move synchronously with the cover plate 216 and can also move independently relative to the cover plate 216. The cover plate 216 is connected to the pressing plate 217 through an elastic member not shown. When the pressing plate 217 moves away from the cover plate 216, the elastic member can provide a restoring force for the pressing plate 217. The threaded fastener 218 is threadedly connected to the cover plate 216. One end of the threaded fastener 218 extends from the top end of the cover plate 216 for easy operation by the operator. The other end not shown can abut against the pressing plate 217. When the cover plate 216 is in the positioning state as shown, the threaded fastener 218 can drive the pressing plate 217 to move towards the base 211 as the threaded fastener 218 is continuously screwed in, so as to clamp the material belt 500 on the base 211 and realize the positioning of the material belt 500 in the thickness direction. Figure 12 It should be noted that the pressing distance of the pressing plate 217 can be adjusted in the present embodiment so as to adapt to material belts 500 of different thicknesses. In addition, the elastic member in the present embodiment is used for the restoring of the pressing plate 217. The pressing force of the pressing plate 217 on the material belt 500 is adjusted by the screwing depth of the threaded fastener 218. Therefore, the pressure is controllable. If the pressing force of the pressing plate 217 on the material belt 500 is provided by the elastic member, the compression amount of the elastic member will change with the change of the thickness of the material belt 500, resulting in the synchronous change of the pressure and making it difficult to stably press the material belt 500.

[0099] Reference is made to Figure 12Further, the cover plate 216 is provided with a plurality of threaded holes 2161 distributed along the width direction of the material belt 500, and the threaded fasteners 218 are provided as at least two, and at least one threaded fastener 218 can be connected with different threaded holes, so as to use the material belt 500 with different widths. For example, as shown in the figure, the cover plate 216 is provided with four threaded holes 2161, and the threaded fasteners 218 are provided as two, one threaded fastener 218 is located in the rightmost threaded hole, and the other threaded fastener 218 is connected with the second, third and fourth threaded holes respectively according to the different widths of the material belt 500.

[0100] In some embodiments, with reference to Figure 12 、 Figure 13 In order to realize the horizontal positioning of the material belt, in addition to the base 211, the positioning assembly 210 further includes a first positioning piece 212, a second positioning piece 213, a driving piece 214 and a limiting piece 215. The first positioning piece 212 is fixedly connected to the base 211, the second positioning piece 213 is slidingly connected to the base 211 and is arranged around the width direction of the material belt 500, and the second positioning piece 213 can move towards the first positioning piece 212 under the driving of the driving piece 214 to abut the material belt 500 against the first positioning piece 212.

[0101] The base is provided with a mounting hole 2112 extending along the width direction of the material belt 500, and the driving piece 214 includes a driving rod 2141 penetrating into the mounting hole 2112, the driving rod 2141 is connected with the second positioning piece 213, specifically, the driving rod 2141 can rotate relative to the second positioning piece 213. The driving rod 2141 has an axially extending plane 2142 on the side, the plane 2142 can be formed on the driving rod 2141 by removing materials, and the distance from the plane 2142 to the center of the driving rod 2141 is less than the diameter of the driving rod 2141.

[0102] The limiting piece 215 is connected to the base 211 and is arranged along the radial direction of the mounting hole 2112, and one end of the limiting piece 215 can extend into the mounting hole 2112 by a certain distance. The limiting piece 215 can be an elastic pin, and the end extending into the mounting hole 2112 has a ball, the ball can elastically move along the axis of the limiting piece 215 by an elastic piece not shown, or the limiting piece 215 is connected with the base 211 by an elastic piece, so that the limiting piece 215 as a whole can elastically move along the axial direction.

[0103] Based on the above structure, when the driving rod 2141 rotates to the position where the plane 2142 faces the limiting piece 215, the plane 2142 is spaced apart from the limiting piece 215 by a certain distance, so that the driving rod 2141 can move axially in the mounting hole 2112, thereby achieving positioning of the material belt 500; after the positioning of the material belt 500 is completed, the driving rod 2141 can rotate to the position where the circular arc surface faces the limiting piece 215, and since the circular arc surface protrudes relative to the plane 2142, the circular arc surface can abut against the limiting piece 215, thereby limiting the axial movement of the driving rod 2141 through the limiting piece 215 to lock the driving rod 2141 at the current position. The embodiment can achieve quick positioning of the material belt 500, has a simple structure, and is convenient to operate.

[0104] The embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
