Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to an aluminum strip connecting mechanism. Background Art

[0002] In the aluminum-plastic composite pipe production line, since the aluminum strip is packaged in a roll, the production line needs to produce continuously and uninterruptedly, which requires that one end of the two rolls of aluminum strip be connected when the aluminum strip is changed for continuous production. In the prior art, spot welding is usually used for welding, but it usually has the following defects: 1. Using overlapping welding method can easily cause the connection part of the aluminum strip to thicken, causing the aluminum strip to damage the forming mold when passing through the subsequent aluminum tube process mold.

[0003] 2. The ends of the aluminum strip are prone to bending and deformation during the welding process, which makes it impossible to accurately align the ends of the new and old aluminum strips, resulting in poor welding quality of the aluminum strip.

[0004] 3. During the welding process of the aluminum strip, some sputtering will be generated at the welding position. The sputtering is easy to sputter onto the surface of the aluminum strip. At this time, the sputtering is in a high temperature state, which will cause damage to the surface of the aluminum strip and affect the subsequent production quality. Summary of the invention

[0005] The object of the present invention is to provide an aluminum strip splicing mechanism to solve the technical problems raised in the above background technology.

[0006] The present invention is achieved through the following technical solutions.

[0007] An aluminum strip splicing mechanism comprises two clamping devices arranged at intervals, the two clamping devices are respectively used to clamp the position near the end of the previous roll of aluminum strip and the position near the head of the next roll of aluminum strip, a lower pressing seat is arranged between the two clamping devices so as to be movable, the lower pressing seat is used to press down the end of the previous roll of aluminum strip and the head of the next roll of aluminum strip; a welding device is movably arranged above the lower pressing seat, the welding device is used to weld the end of the previous roll of aluminum strip and the head of the next roll of aluminum strip; Among them, the lower press seat is provided with a welding channel along the second direction, and a revealing window connected to the welding channel is opened on the lower side of the lower press seat, and the revealing window extends along the second direction so that the end of the previous roll of aluminum strip and the beginning of the next roll of aluminum strip are exposed under the welding device.

[0008] As a further improvement of the present invention, the clamping device includes a base and a mounting seat arranged on one side of the base, the mounting seat has a limiting surface close to the side of the base, and the limiting surfaces of the mounting seats of the two clamping devices are located in the same plane; An upper plate, one end of which is connected to the upper end of the mounting seat and the other end of which is horizontally extended toward one side of the base, so that there is a preset distance between the upper plate and the base; A pressing plate is arranged between the upper plate and the base in a liftable manner to press the aluminum strip.

[0009] As a further improvement of the present invention, it also includes a cutter, which can be raised and lowered and arranged on the lower side of the lower pressure seat. The cutter can be inserted into the revealing window, and the side wall of the cutter is in contact with the side wall of the revealing window when the cutter is inserted into the revealing window.

[0010] As a further improvement of the present invention, the upper end surface of the cutter and the upper end surface of the base are located in the same horizontal plane.

[0011] As a further improvement of the present invention, the base can slide back and forth along the third direction to drive the end of the previous roll of aluminum strip and the beginning of the next roll of aluminum strip to approach each other.

[0012] As a further improvement of the present invention, the welding channel and the sliding direction of the base have a preset angle.

[0022] The present invention is further described in detail below based on the accompanying drawings and implementation examples.

[0023] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0024] refer to Figures 1 to 5 , the embodiments of the present invention disclose: The cam 200 is a kind of aluminum strip splicing mechanism, comprising a workbench 1, on which two clamping devices are arranged at intervals, and the two clamping devices are respectively used to clamp the aluminum strip 101 near the end portion of the previous roll and the aluminum strip 101 near the head portion of the next roll, specifically, the clamping device comprises a base 2, a mounting seat 3 arranged on one side of the base 2, an upper top plate 4 is arranged on the upper end of the mounting seat 3, one end of the upper top plate 4 is connected to the upper end of the mounting seat 3, and the other end is horizontally extended to one side of the base 2, so that there is a preset distance between the upper top plate 4 and the base 2, and a pressing plate is arranged between the upper top plate 4 and the base 2 to press the aluminum strip 101, and at the same time, a first telescopic cylinder 5 is arranged on the upper top plate 4, and the output end of the first telescopic cylinder 5 penetrates between the upper top plate 4 and the base 2, and is connected to the upper end of the pressing plate, so as to control the pressing plate to be lifted and lowered, and then press the aluminum strip 101; in addition, in the present embodiment In the embodiment, the two bases 2 can slide back and forth along the third direction (left and right direction as shown in the figure) to drive the end of the previous roll of aluminum strip 101 and the beginning of the next roll of aluminum strip 101 to approach each other. Specifically, a second telescopic cylinder (not shown in the figure) is arranged in the workbench 1 along the third direction (left and right direction), and the output end of the second telescopic cylinder is connected to the bottom of the base 2, so that when the output end of the second telescopic cylinder is telescoped, the base 2 can be driven to move along the third direction (left and right direction); when working, the aluminum strip 101 is controlled to be located between the base 2 and the pressure plate, and then the pressure plate is controlled to descend, that is, the aluminum strip 101 is pressed, and finally, the base 2 is controlled to slide by the second telescopic cylinder. At this time, the aluminum strip 101 clamped on the base 2 is forced to move toward the middle position of the two clamping devices, that is, the end of the previous roll of aluminum strip 101 and the beginning of the next roll of aluminum strip 101 are close to each other, so as to carry out the subsequent process (welding).

[0025] In the process of installing the aluminum strip 101, if the two ends of the aluminum strip 101 are not aligned, the end of the previous roll of aluminum strip 101 and the beginning of the next roll of aluminum strip 101 will be misaligned when they are close to each other, thereby affecting the subsequent welding effect. Based on this, in this embodiment, the mounting seat 3 has a limiting surface 6 on the side close to the base 2, and the limiting surfaces 6 of the mounting seats 3 of the two clamping devices are located in the same plane. Before the control pressure plate moves downward to press the aluminum strip 101, the aluminum strip 101 is controlled to move in the direction of the limiting surface 6 so that the aluminum strip 101 is The side wall of the strip 101 is against the limiting surface 6, and then the pressure plate is controlled to move downward. At this time, since the limiting surfaces 6 of the mounting seats 3 on both sides are located in the same plane, the side wall of the end portion of the previous roll of aluminum strip 101 is aligned with the side wall of the beginning portion of the next roll of aluminum strip 101. At the same time, since the aluminum strips 101 have the same size and width, the two aluminum strips 101 away from the limiting surface 6 are also aligned with each other (the ends of the aluminum strips 101 are aligned), so that the aluminum strips 101 can be accurately aligned during the installation process to avoid affecting the subsequent (welding) process.

[0026] A welding device is movably arranged above the lower pressure seat 11, and the welding device is used to weld the end portion of the previous roll of aluminum strip 101 with the beginning portion of the next roll of aluminum strip 101. As shown in the figure, the welding device in the present application includes a welding gun 7. Specifically, a column 8 is arranged on one side of the clamping device on the workbench 1, and a horizontal sliding seat 9 is transversely arranged on the column 8. A first slide rail is arranged on the horizontal sliding seat 9, and a vertical sliding seat 10 is arranged on the first slide rail. At the same time, a first driving motor is arranged on one side of the horizontal sliding seat 9, and the first driving motor is transmission-connected to the vertical sliding seat 10 for driving the vertical sliding seat 10 slides on the first slide rail; at the same time, a second slide rail is arranged on the vertical sliding seat 10, and a welding gun 7 is slidably arranged on the second slide rail, and a second driving motor is arranged on the upper end of the vertical sliding seat 10 to drive the welding gun 7 to slide in the vertical direction, so as to realize the lifting function; the aluminum strip 101 can pass through the lower side of the horizontal sliding seat 9, and the output end of the welding gun 7 is facing downward, specifically toward the end of the previous roll of aluminum strip 101 and the beginning of the next roll of aluminum strip 101 are close to and fit together; the end of the previous roll of aluminum strip 101 and the beginning of the next roll of aluminum strip 101 are welded by the welding gun 7.

[0027] Since the aluminum strip 101 is packaged in a coil, after a section of the aluminum strip 101 is pulled out, the aluminum strip 101 has a certain elasticity due to its own properties, that is, the section of the aluminum strip 101 will be elastically reset to a certain extent when not subjected to external force, and the section of the aluminum strip 101 will be in a bent state when not subjected to external force. Correspondingly, in this embodiment, the end of the previous roll of the aluminum strip 101 and the beginning of the next roll of the aluminum strip 101 will also be in a bent state. In the process of the end of the previous roll of the aluminum strip 101 and the beginning of the next roll of the aluminum strip 101 approaching and fitting each other, even if the two aluminum strips 101 The side walls between the two aluminum strips 101 are aligned with each other (aligned in the width direction), but the ends of the two aluminum strips 101 may not be aligned in the vertical direction (for example, one section of the aluminum strip 101 faces upward and the other section of the aluminum strip 101 faces downward), or there may be a certain gap between the ends of the two aluminum strips 101 (when both sections of the aluminum strips 101 are bent but the ends are of equal height, when the ends of the two sections of the aluminum strips 101 are close to each other and fit together, the upper parts of the ends may abut against each other while the lower parts of the ends still have a certain gap), or the aluminum strips 101 may overlap each other (due to the bending of the aluminum strips 101 state, it is not easy to control the clamping length of the aluminum strip 101), based on this, in the present application, a lower pressure seat 11 is arranged between the two clamping devices, and specifically, a lifting platform 12 is arranged on one side of the clamping device on the workbench 1, and a lifting slide rail is vertically arranged on the lifting platform 12, and a sliding seat can be lifted and lowered on the lifting slide rail, and one end of the lower pressure seat 11 is connected to the sliding seat, and a driving motor is also arranged on the workbench 1, and the driving motor is connected to the sliding seat for driving the sliding seat to lift and lower, and the workbench 1 is provided with a lifting and lowering mechanism. 11 is used to press downward the end of the previous roll of aluminum strip 101 and the beginning of the next roll of aluminum strip 101; specifically, during operation, the lower pressing seat 11 moves downward and presses down to the end of the previous roll of aluminum strip 101 and the beginning of the next roll of aluminum strip 101. Since the lower side of the lower pressing seat 11 has a preset width, the compressed portion of the aluminum strip 101 can be straight, so that the end of the previous roll of aluminum strip 101 and the beginning of the next roll of aluminum strip 101 can be straight, and the two are aligned with each other, that is, through the above-mentioned arrangement, the aluminum strip 101 has a smooth seam without overlap during welding.

[0028] In this embodiment, the lower pressing seat 11 is provided with a welding channel 13, and the lower end of the welding device (welding gun 7) can slide in the welding channel 13, wherein the lower pressing seat 11 is provided with a welding channel 13 for the lower end of the welding device to penetrate along a first direction (as shown in the figure, along the up and down direction) and slide along a second direction (along the width direction of the aluminum strip), and the lower side of the lower pressing seat 11 is provided with a revealing window 14 connected to the welding channel 13, and the revealing window 14 extends along the second direction so that the end of the previous roll of aluminum strip 101 and the beginning of the next roll of aluminum strip 101 are exposed under the welding device, and the revealing window 14 allows the welding end of the welding device (welding gun 7) to be exposed. The end portion (the portion to be welded) of the previous roll of the aluminum strip 101 and the beginning portion (the portion to be welded) of the next roll of the aluminum strip 101 can be welded, that is, the welding function can be realized; in addition, during the welding process, a certain amount of welding spatter will be generated. At this time, the side wall of the exposure window 14 and the welding channel 13 can also be used to prevent the welding spatter from splashing onto the surface of the aluminum strip 101 during welding, that is, when the welding spatter is splashed, it will touch the side wall of the exposure window 14 and the inner wall of the welding channel 13, thereby limiting the welding spatter from splashing out of the lower pressure seat 11 and splashing onto the surface of the aluminum strip 101, thereby avoiding damage to the surface of the aluminum strip 101, so as to improve the production quality of the product.

[0029] In addition, the lower pressing seat 11 is usually made of iron alloy during the specific implementation process, while the aluminum strip 101 is of low hardness. If the lower end of the lower pressing seat 11 is quickly pressed downward to directly press the aluminum strip 101, it will be in hard contact with the aluminum strip 101, which may easily cause damage to the aluminum strip 101, thereby affecting the subsequent production quality. Based on this, a pressing plate 15 is provided at the lower side of the lower pressing seat 11, and a lifting rod is provided on the pressing plate 15 and penetrates upward into the welding channel 13. The end of the lifting rod that penetrates the welding channel 13 is provided with an anti- The end head is removed, and a buffer spring is arranged on the lifting rod between the clamping plate 15 and the lower pressure seat 11, and the clamping plate 15 is avoided in the revealing window 14. During the descending process of the lower pressure seat 11, the clamping plate 15 will first contact the aluminum strip 101 and press the aluminum strip 101. At this time, the buffer spring can play a buffering role to prevent the lower pressure seat 11 from descending too fast and causing damage to the aluminum strip 101. When the aluminum strip 101 is in a straight state, it stops descending, and the function of pressing the aluminum strip 101 is completed.

[0030] During the production process, the end surface of the tail end of the previous roll of aluminum strip 101 and the end surface of the head end of the next roll of aluminum strip 101 may be irregular. If the two are directly controlled to be close to each other, it is easy to cause poor contact of the aluminum strip 101, thereby affecting the welding process. Based on this, a shearing device is further provided on the workbench 1 in the present application and between the two clamping devices, so that the end of the aluminum strip 101 is first sheared, and then the aluminum strip 101 is welded, so as to improve the welding quality of the aluminum strip 101; specifically, the shearing device includes a cutter 16, the number of the cutters 16 is two and they are arranged side by side and close to each other, the cutter 16 can be raised and lowered and arranged at the lower side of the lower pressing seat 11, the cutter 16 can be inserted into the revealing window 14, and the side wall of the cutter 16 fits with the side wall of the revealing window 14 when penetrating into the revealing window 14; specifically A shearing notch is provided on the workbench 1, and the shearing notch is connected to the inside of the workbench 1. Two telescopic cylinders (not shown in the figure) are provided inside the workbench 1, and their output ends are respectively connected to the bottoms of the two cutters 16, thereby driving each cutter 16 to rise and fall. When the cutter 16 is not rising, the upper end surface and the upper end surface of the base 2 are located in the same horizontal plane; in addition, shearing seats are also provided on both sides of the shearing notch, and the shearing seats are aligned with the pressing plate 15. When the aluminum strip 101 is located between the lower pressing seat 11 and the cutter 16, the cutter 16 rises, and the cutter 16 fits with the side wall of the exposure window 14 during the rising process, and a shearing force is generated between the two, thereby achieving a shearing effect on the aluminum strip 101; after being sheared, the aluminum strip 101 moves closer to each other, so that the ends of the aluminum strip 101 can directly contact without a gap, thereby improving the welding quality.

[0031] The welding channel 13 has a preset angle with the sliding direction of the base 2 (in this embodiment, the middle angle is 20-30 degrees). Correspondingly, the exposure window 14 has a preset angle with the sliding direction of the base 2. More specifically, in this application, the lower pressure seat 11 has a preset angle with the sliding direction of the base 2. At the same time, in order to adapt to the exposure window 14, the welding channel (13) has a preset angle with the sliding direction of the base (2) along the extension direction (i.e., the second direction), so that the cutter 16 has a certain angle in the width direction of the aluminum strip 101, so that there is a certain angle between the cutting edge of the aluminum strip 101 and the side wall of the aluminum strip 101, thereby lengthening the length of the cutting edge. If the aluminum strip 101 is welded at this time, the total welding length of the aluminum strip 101 is increased, thereby making the welding of the two aluminum strips 101 more reliable.

[0032] A positioning seat 17 is provided on one side of the cutter 16, and a positioning hole is opened on the positioning seat 17. A positioning column is provided on the lower side of the lower pressing seat 11. The outer diameter of the positioning column is adapted to the inner diameter of the positioning hole. The positioning column is aligned with the positioning hole so that the positioning column can be inserted into the positioning hole when the lower pressing seat 11 descends to a predetermined position.

[0033] Working principle: The working sequence in this embodiment is: 1. Install the aluminum strip 101, control the side wall of the aluminum strip 101 to press against the limit surface 6 of the mounting seat 3, and then control the pressure plate of the clamping device so that the pressure plate and the base 2 cooperate to press the aluminum strip 101; in this step, the previous roll of aluminum strip 101 is clamped by the clamping devices on both sides respectively with the next roll of aluminum strip 101.

[0034] 2. Control the base 2 to move toward the cutter 16 so that the end portion of the previous roll of aluminum strip 101 is located above the cutter 16, and the beginning portion of the next roll of aluminum strip 101 is located above the cutter 16, then control the lower press seat 11 to descend, and then control the cutter 16 to ascend, that is, cut the aluminum strip 101; after cutting is completed, control the lower press seat 11 to ascend and the cutter 16 to descend to achieve reset.

[0035] 3. Control the base 2 to move toward the cutter 16 again, so that the ends of the two aluminum strips 101 are close to each other and fit together, and then control the lower pressing seat 11 to descend again to press the aluminum strip 101 tightly.

[0036] 4. Control the welding gun 7 to move to the right position and weld the joints of the two ends of the aluminum strips 101. After welding, control the welding gun 7 to reset and the lower pressing seat 11 to reset. At the same time, control the pressing plate to rise and reset, and no longer press the aluminum strip 101. At this time, the aluminum strip 101 is connected.

[0037] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned implementation cases, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned implementation cases, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
