Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic cell assembly production, and specifically to a welding strip anti-flipping mechanism and a welding strip processing device. Background Art

[0002] The stringer is a device used to lay, stack, and weld battery cells and welding ribbons to form a battery string. The welding ribbon feeding mechanism is an important component of the stringer, which is used to realize the online loading of welding ribbons. The existing welding ribbon feeding mechanism usually includes a welding ribbon unwinding mechanism, a welding ribbon clamping mechanism, a welding ribbon cutting mechanism, and a traction mechanism, which are arranged in sequence. However, the distance between the welding ribbon unwinding mechanism and the welding ribbon clamping mechanism is far. For the flat welding ribbon, when the traction mechanism pulls the welding ribbon to move, in the distance from the welding ribbon unwinding mechanism to the welding ribbon clamping mechanism, due to the lack of corresponding welding ribbon control, the welding ribbon is prone to flipping and twisting during the movement, affecting the subsequent use. Utility Model Content

[0003] In view of the above-mentioned problems existing in the process of soldering ribbon moving, the present application provides a soldering ribbon anti-flipping mechanism, and its specific solution is as follows:

[0004] A welding strip anti-flipping mechanism comprises a lower pressing roller and an upper pressing roller, wherein a gap is formed between the upper pressing roller and the lower pressing roller for n welding strips to pass through;

[0005] The upper pressing roller is configured to elastically press the n solder strips passing through the gap against the lower pressing roller, and the contact surfaces of the upper pressing roller and the lower pressing roller with the solder strips are both smooth surfaces.

[0006] The solder strip anti-flipping mechanism of the present application can be arranged at a position between the solder strip unwinding mechanism and the solder strip pressing mechanism, by passing the solder strip through the gap between the upper pressing roller and the lower pressing roller, and making the upper pressing roller elastically press the lower pressing roller, so that the upper pressing roller and the lower pressing roller rotate with the movement of the solder strip, thereby preventing the solder strip from flipping and twisting during the transportation process from the solder strip unwinding mechanism to the solder strip pressing mechanism; the contact surfaces of the upper pressing roller and the lower pressing roller with the solder strip are both smooth surfaces, which can avoid scratching the solder strip during the transmission of the solder strip.

[0007] In some embodiments, the welding strip anti-flip mechanism also includes: two first lower pressure roller mounting seats arranged at intervals, and the lower pressure roller is rotatably mounted between the two first lower pressure roller mounting seats; two first upper pressure roller mounting seats arranged at intervals and corresponding one-to-one with the first lower pressure roller mounting seats, wherein the upper pressure roller is rotatably mounted between the two first upper pressure roller mounting seats.

[0008] By rotatably mounting the lower pressing roller on the first lower pressing roller mounting seat, and rotatably mounting the upper pressing roller on the first upper pressing roller mounting seat, the upper pressing roller and the lower pressing roller can be driven to rotate when the welding strip moves.

[0009] In some embodiments, the first upper pressing roller mounting seat is mounted on a first elastic pressing mechanism, and the first elastic pressing mechanism is used to press the first upper pressing roller mounting seat downward so that the upper pressing roller elastically presses the n welding ribbons onto the lower pressing roller.

[0010] A downward pressure is applied to the first upper pressing roller mounting seat through the first elastic pressing mechanism, thereby driving the upper pressing roller downward to elastically press the welding strip against the lower pressing roller.

[0011] In some embodiments, the first elastic clamping mechanism includes a first guide column and a first spring, wherein: the lower end of the first guide column is fixedly connected to the first lower pressure roller mounting seat, and the upper end of the first guide column is provided with a first limiting ring; the first upper pressure roller mounting seat is slidably connected to the first guide column, the first spring is sleeved on the first guide column, the upper end of the first spring abuts against the first limiting ring, and the lower end of the first spring abuts against the first upper pressure roller mounting seat.

[0012] Since the first upper pressure roller mounting seat is slidably connected to the first guide column, the upper end of the first spring abuts against the limiting ring at the upper end of the first guide column, and the lower end abuts against the first upper pressure roller mounting seat, so that the first spring always applies a downward pressure to the first upper pressure roller mounting seat, so that the upper pressure roller elastically presses the welding strip onto the lower pressure roller.

[0013] In some embodiments, the welding strip anti-flipping mechanism also includes: two second lower pressure roller mounting seats arranged at intervals, and the lower pressure roller is rotatably mounted between the two second lower pressure roller mounting seats; n second upper pressure roller mounting seats, and an upper pressure roller is rotatably mounted on each second upper pressure roller mounting seat, and each upper pressure roller is configured to elastically press a welding strip onto the lower pressure roller.

[0014] The lower pressing roller is rotatably mounted on the second lower pressing roller mounting seat, and n upper pressing rollers are rotatably mounted one-to-one on the second upper pressing roller mounting seat, and only one welding strip is allowed to pass between each upper pressing roller and the lower pressing roller. When there is a difference in thickness between different welding strips, the corresponding upper pressing roller can float according to the thickness of the welding strip, thereby ensuring that each welding strip can be elastically compressed.

[0015] In some embodiments, the welding strip anti-flipping mechanism also includes a second elastic clamping mechanism; the second elastic clamping mechanism includes n movable parts; each second upper pressure roller mounting seat is independently connected to a movable part of the second elastic clamping mechanism, and the second elastic clamping mechanism is used to squeeze each second upper pressure roller mounting seat downward so that each upper pressure roller elastically presses the corresponding welding strip onto the lower pressure roller.

[0016] By connecting the movable part of the second elastic clamping mechanism to each second upper pressing roller mounting seat individually, the second elastic clamping mechanism can apply downward force to each second upper pressing roller mounting seat respectively, so that the upper pressing roller elastically presses the corresponding welding strip onto the lower pressing roller.

[0017] In some embodiments, the second elastic clamping mechanism includes a top plate and n elastic clamping components, wherein: both ends of the top plate are respectively fixedly mounted on a second lower pressure roller mounting seat, and the n elastic clamping components are arranged side by side on the top plate; a second upper pressure roller mounting seat is correspondingly mounted on each elastic clamping component, and the elastic clamping component is used to squeeze the corresponding second upper pressure roller mounting seat downward so that the corresponding upper pressure roller presses the corresponding welding strip onto the lower pressure roller.

[0018] An elastic clamping mechanism is provided. By installing an elastic clamping component one-to-one at the corresponding position of the second upper pressing roller mounting seat, each welding strip can be individually pressed on the lower pressing roller by the upper pressing roller, thereby realizing one-to-one floating clamping of the welding strips, adapting to the thickness of different welding strips, and ensuring that each welding strip can be individually clamped.

[0019] In some embodiments, the elastic clamping assembly includes a second guide column and a second spring, wherein: the upper end of the second guide column can slide up and down through the top plate, a second limiting ring is provided on the second guide column located above the top plate, and the lower end of the second guide column is fixedly connected to the second upper pressure roller mounting seat; the second spring is sleeved on the second guide column, the upper end of the second spring abuts against the top plate, and the lower end of the second spring abuts against the second upper pressure roller mounting seat.

[0020] Since the second guide column is slidably connected to the top plate, the upper end of the second spring abuts against the top plate, and the lower end abuts against the second upper pressure roller mounting seat, so that the second spring always gives the second upper pressure roller mounting seat a downward force, so that the upper pressure roller presses the corresponding welding strip onto the lower pressure roller.

[0021] In some embodiments, the welding strip anti-flipping mechanism also includes a roller shaft, and the lower pressure roller includes n roller sleeves, wherein: both ends of the roller shaft are respectively fixedly mounted on a second lower pressure roller mounting seat; the n roller sleeves are spaced along the length direction of the roller shaft and rotatably sleeved on the roller shaft, each roller sleeve corresponds to an upper pressure roller, and the upper pressure roller elastically presses the welding strip onto the corresponding roller sleeve.

[0022] By setting the roller sleeve on the lower pressure roller in one-to-one correspondence with the upper pressure roller, each welding strip has a separate upper pressure roller and roller sleeve, so as to achieve one-to-one compression of the welding strip, and the roller sleeve and upper pressure roller at each welding strip can rotate to adapt to the corresponding welding strip speed, so as to better control the welding strip.

[0023] In some embodiments, a limiting groove is provided on one or both sides of the upper pressure roller at the bottom of the second upper pressure roller mounting seat, and the limiting groove extends along the advancing direction of the welding strip, and the width of the limiting groove is adapted to the width of the upper pressure roller.

[0024] The limiting groove arranged at the bottom of the second upper pressing roller mounting seat can prevent the welding strip from slipping out of the range of the upper pressing roller.

[0050] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] A welding strip anti-flipping mechanism 2 provided in the present application includes a lower pressing roller 22 and an upper pressing roller 21, wherein a gap is formed between the upper pressing roller 21 and the lower pressing roller 22 for n welding strips 6 to pass through; the upper pressing roller 21 is configured to elastically press the n welding strips 6 passing through the gap against the lower pressing roller 22, and the contact surfaces of the upper pressing roller 21 and the lower pressing roller 22 with the welding strips 6 are both smooth surfaces.

[0052] The solder strip anti-flipping mechanism 2 of the present application can be arranged at a position between the solder strip unwinding mechanism 1 and the solder strip clamping mechanism 3, by passing the solder strip 6 through the gap between the upper pressing roller 21 and the lower pressing roller 22, and making the upper pressing roller 21 elastically press the lower pressing roller 22, so that the upper pressing roller 21 and the lower pressing roller 22 rotate with the movement of the solder strip 6, thereby preventing the solder strip 6 from flipping and twisting during the transportation from the solder strip unwinding mechanism 1 to the solder strip clamping mechanism 3; the contact surfaces of the upper pressing roller 21 and the lower pressing roller 22 with the solder strip 6 are both smooth surfaces, which can avoid scratching the solder strip during the transmission of the solder strip.

[0053] It should be noted that the welding strip anti-flipping mechanism 2 of the present application has a relatively small pressing force on the welding strip by the upper pressing roller 21 and the lower pressing roller 22. As long as it can be ensured that the welding strip does not flip or slip when passing between the two, there is no need to set the pressing force between the upper pressing roller 21 and the lower pressing roller 22 too large to avoid deforming the welding strip.

[0054] like Figure 1 As shown, the welding strip anti-flipping mechanism 2 in the first embodiment includes two first lower pressure roller mounting seats 24 arranged at intervals, and a lower pressure roller 22 rotatably mounted between the two first lower pressure roller mounting seats 24; two first upper pressure roller mounting seats 23 arranged at intervals and corresponding one by one to the first lower pressure roller mounting seats 24, and an upper pressure roller 21 rotatably mounted between the two first upper pressure roller mounting seats 23.

[0055] In this way, the lower pressing roller 22 and the upper pressing roller 21 are rotatably mounted on the first lower pressing roller mounting seat 24 and the first upper pressing roller mounting seat 23 respectively, ensuring that the upper pressing roller 21 and the lower pressing roller 22 can be driven to rotate when the welding strip 6 moves.

[0056] Optionally, the rotational mounting method between the lower pressing roller 22 and the first lower pressing roller mounting seat 24 may be any of the following:

[0057] Method 1: The lower pressure roller 22 is rotatably mounted on the roller shaft through a bearing, and both ends of the roller shaft are fixed on the first lower pressure roller mounting seat 24.

[0058] Mode 2: Both ends of the lower pressing roller 22 are rotatably mounted on the first lower pressing roller mounting seat 24 via bearings.

[0059] Optionally, the rotational mounting method between the upper pressing roller 21 and the first upper pressing roller mounting seat 23 is similar.

[0060] The first upper pressing roller mounting seat 23 is mounted on the first elastic pressing mechanism 25 , and the first elastic pressing mechanism 25 is used to press the first upper pressing roller mounting seat 23 downward, so that the upper pressing roller 21 elastically presses the n welding strips 6 onto the lower pressing roller 22 .

[0061] Optionally, the first elastic pressing mechanism 25 may be mounted on the first lower pressing roller mounting seat 24 , or may be provided independently of the first lower pressing roller mounting seat 24 .

[0062] Optionally, in the first embodiment, as Figure 1 As shown, the first elastic clamping mechanism 25 includes a first guide column 251 and a first spring 252. The lower end of the first guide column 251 is fixedly connected to the first lower pressure roller mounting seat 24, and the upper end of the first guide column 251 is provided with a first limiting ring 253; the first upper pressure roller mounting seat 23 is slidably connected to the first guide column 251, and the first spring 252 is sleeved on the first guide column 251. The upper end of the first spring 252 abuts against the first limiting ring 253, and the lower end of the first spring 252 abuts against the first upper pressure roller mounting seat 23.

[0063] The working principle of the first elastic clamping mechanism 25 that enables the upper pressure roller 21 to elastically press n welding strips onto the lower pressure roller 22 is as follows: since the first upper pressure roller mounting seat 23 is slidably connected to the first guide column 251, the upper end of the first spring 252 abuts against the limiting ring at the upper end of the first guide column 251, and the lower end abuts against the first upper pressure roller mounting seat 23, so that the first spring 252 always applies a downward pressure to the first upper pressure roller mounting seat 23, so that the upper pressure roller 21 can elastically press the welding strip 6 onto the lower pressure roller 22.

[0064] Optionally, in a second embodiment, the first elastic clamping mechanism 25 includes a first guide post, a lower fixing seat and a first spring, and the lower fixing seat is independently provided from the first lower pressure roller mounting seat 24. The lower end of the first guide post is fixedly connected to the lower fixing seat, and the upper end of the first guide post is provided with a first limiting ring; the first upper pressure roller mounting seat 23 is slidably connected to the first guide post, the first spring is sleeved on the first guide post, the upper end of the first spring abuts against the first limiting ring, and the lower end of the first spring abuts against the first upper pressure roller mounting seat 23.

[0065] Optionally, in the third embodiment, the first elastic clamping mechanism 25 includes a first guide post, an upper fixed seat and a first spring, and the upper fixed seat is hoisted above the first lower pressure roller mounting seat. The lower end of the first guide post is fixedly connected to the first upper pressure roller mounting seat 23, and the upper end of the first guide post is provided with a first limiting ring after sliding through the upper fixed seat; the first spring is sleeved on the first guide post, the upper end of the first spring abuts on the upper fixed seat, and the lower end of the first spring abuts on the first upper pressure roller mounting seat 23.

[0066] The installation method of the first elastic clamping mechanism 25 of the present application includes but is not limited to the above three implementation methods. As long as the first elastic clamping mechanism 25 can press the first upper pressure roller mounting seat 23 downward so that the upper pressure roller 21 elastically presses n welding strips onto the lower pressure roller 22, it belongs to the protection scope of the present application.

[0067] In embodiment 1, the upper pressing roller 21 presses the pulled one or more welding strips 6 onto the lower pressing roller 22 through the first elastic pressing mechanism 25, and the upper pressing roller 21 does not need to apply too much force to press the welding strip 6 to prevent the welding strip 6 from being deformed; this embodiment has a simple structure, is easy to install, and has low cost.

[0068] like Figure 2 As shown, the welding strip anti-flipping mechanism 2 in the second embodiment includes two second lower pressure roller mounting seats 27 arranged at intervals, a lower pressure roller 22 rotatably mounted between the two second lower pressure roller mounting seats 27; n second upper pressure roller mounting seats 26, each of which has an upper pressure roller 21 rotatably mounted thereon, and each upper pressure roller 21 is configured to elastically press a welding strip 6 onto the lower pressure roller 22.

[0069] In this way, the lower pressure roller 22 is rotatably installed on the second lower pressure roller mounting seat 27, and the n upper pressure rollers 21 are rotatably installed one-to-one on the second upper pressure roller mounting seat 26, and only one welding strip is allowed to pass between each upper pressure roller 21 and the lower pressure roller 22, so that when there is a difference in thickness between different welding strips, the corresponding upper pressure roller 21 can float according to the thickness of the welding strip, ultimately ensuring that each welding strip can be elastically compressed.

[0070] Continue to refer Figure 3 and Figure 4 The welding strip anti-flipping mechanism 2 in the second embodiment also includes a second elastic clamping mechanism; the second elastic clamping mechanism includes n movable parts; each second upper pressure roller mounting seat 26 is independently connected to a movable part of the second elastic clamping mechanism, and the second elastic clamping mechanism is used to press each second upper pressure roller mounting seat 26 downward so that each upper pressure roller 21 elastically presses the corresponding welding strip 6 onto the lower pressure roller 22.

[0071] Optionally, the second elastic clamping mechanism includes a top plate 28 and n elastic clamping components 29, wherein both ends of the top plate 28 are respectively fixedly mounted on a second lower pressure roller mounting seat 27, and the n elastic clamping components 29 are arranged side by side on the top plate 28; each elastic clamping component 29 is correspondingly mounted with a second upper pressure roller mounting seat 26, and the elastic clamping component 29 is used to squeeze the corresponding second upper pressure roller mounting seat 26 downward so that the corresponding upper pressure roller 21 presses the corresponding welding strip 6 onto the lower pressure roller 22.

[0072] Optionally, in addition to being fixedly mounted on the second lower pressure roller mounting seat 27, both ends of the top plate 28 can also be independently set from the second lower pressure roller mounting seat 27, as long as it can be ensured that the n elastic clamping components 29 can squeeze the corresponding second upper pressure roller mounting seat 26 downward.

[0073] An elastic clamping mechanism is provided, by installing the fixed component in the second elastic mechanism, i.e., the top plate 28, on the second lower pressure roller mounting seat 27, and arranging the elastic clamping assembly 29 on the top plate 28 and installing the second upper pressure roller mounting seats 26 one by one, so that the welding strip 6 at each second upper pressure roller mounting seat 26 can be individually pressed onto the lower pressure roller 22 by the upper pressure roller 21, thereby realizing one-to-one elastic clamping of the welding strip 6.

[0074] Optional, such as Figure 5 As shown, the elastic clamping assembly 29 includes a second guide column 291 and a second spring 292. The upper end of the second guide column 291 can slide up and down through the top plate 28. A second limiting ring is provided on the second guide column 291 located above the top plate 28. The lower end of the second guide column 291 is fixedly connected to the second upper pressure roller mounting seat 26; the second spring 292 is sleeved on the second guide column 291, the upper end of the second spring 292 abuts against the top plate 28, and the lower end of the second spring 292 abuts against the second upper pressure roller mounting seat 26.

[0075] The working principle of the elastic pressing component 29 that enables the upper pressing roller 21 at this location to elastically press the welding strip 6 onto the lower pressing roller 22 is as follows: since the second guide column 291 is slidably connected to the top plate 28, the upper end of the second spring 292 abuts against the top plate 28, and the lower end abuts against the second upper pressing roller mounting seat 26, so that the second spring 292 always gives the second upper pressing roller mounting seat 26 a downward force, thereby causing the upper pressing roller 21 to press the corresponding welding strip 6 onto the lower pressing roller 22.

[0076] Continue to refer Figure 2 The welding strip anti-flipping mechanism 2 also includes a roller shaft 210, and the lower pressure roller includes n roller sleeves 200. The two ends of the roller shaft 210 are respectively fixedly mounted on a second lower pressure roller mounting seat 27; the n roller sleeves 200 are spaced along the length direction of the roller shaft 210 and rotatably sleeved on the roller shaft 210, and each roller sleeve 200 corresponds to an upper pressure roller 21, and the upper pressure roller 21 elastically presses the welding strip 6 onto the corresponding roller sleeve 200.

[0077] By setting the roller sleeve 200 on the lower pressure roller 22 and the upper pressure roller 21 in a one-to-one correspondence, each welding strip can be elastically pressed on the roller sleeve 200 by a separate upper pressure roller 21, so as to achieve one-to-one pressing of the welding strip 6, and the roller sleeve 200 and the upper pressure roller 21 at each welding strip 6 can rotate to adapt to the corresponding welding strip 6 speed, so as to better control the welding strip 6.

[0078] Continue to refer Figure 5 The bottom of the second upper pressure roller mounting seat 26 is located on one side or both sides of the upper pressure roller 21 and is provided with a limiting groove 261, which extends along the advancing direction of the welding strip. The width of the limiting groove 261 is adapted to the width of the upper pressure roller 21, which can prevent the welding strip 6 from slipping out of the range of the upper pressure roller 21.

[0079] In the second embodiment, each upper pressing roller 21 is provided with an elastic clamping assembly 29 to press a single welding strip 6 onto the roller sleeve 200 of the lower pressing roller, thereby realizing one-to-one clamping of the welding strip 6, which can adapt to welding strips 6 of different thicknesses, and ensure that each welding strip 6 can be clamped individually to avoid the welding strip 6 from moving during the conveying process; at the same time, during the one-to-one clamping, each set of pressing rollers can adapt to the speed of the corresponding welding strip 6 to rotate, so as to better control the welding strip.

[0080] like Figure 6 As shown, the utility model also provides a solder strip processing device, comprising a solder strip unwinding mechanism 1, at least one solder strip anti-flipping mechanism 2 (which may be at least one of the first and second embodiments), a solder strip clamping mechanism 3, a solder strip cutting mechanism 4 and a traction mechanism 5 which are arranged in sequence, wherein the solder strip unwinding mechanism 1 is used to release n solder strips; the traction mechanism 5 is used to clamp and pull the n solder strips released by the solder strip unwinding mechanism 1, so that the n solder strips pass through the solder strip anti-flipping mechanism 2, the solder strip clamping mechanism 3 and the solder strip cutting mechanism 4 in sequence; the solder strip anti-flipping mechanism 2 is used to prevent the solder strip from flipping during the transportation process from the solder strip unwinding mechanism 1 to the solder strip clamping mechanism 3; the solder strip clamping mechanism 3 is used to clamp the solder strip; the solder strip cutting mechanism 4 is used to cut the solder strip after the solder strip clamping mechanism 3 clamps the solder strip.

[0081] It can be seen that the present application realizes the control of the solder ribbon 6 in the section between the solder ribbon unwinding mechanism 1 and the solder ribbon clamping mechanism 3 by setting at least one solder ribbon anti-flipping mechanism 2 between the solder ribbon unwinding mechanism 1 and the solder ribbon clamping mechanism 3, so that the solder ribbon 6 will not flip or twist during the movement.

[0082] like Figure 7 As shown, the solder strip processing device also includes a solder strip pressure rod assembly arranged between the solder strip unwinding mechanism 1 and the solder strip anti-flipping mechanism 2, the solder strip pressure rod assembly includes two pressure rod seats 71 arranged at intervals, and pressure rods 72 respectively installed on a pressure rod seat at both ends. The solder strip released by the solder strip unwinding mechanism 1 passes through the gap between the lower pressure roller 22 and the upper pressure roller 21 of the solder strip anti-flipping mechanism 2 under the pressure rod 72, and the pressure rod 72 is used to press the solder strip first to prevent the solder strip from jumping.

[0083] Continue to refer Figure 7 The solder strip processing device further includes a guide comb 8 disposed between the solder strip anti-flipping mechanism 2 and the solder strip pressing mechanism 3, and the guide comb 8 is provided with guide grooves 81 corresponding to the n solder strips 6. The setting of the guide comb 8 enables the solder strips in the solder strip anti-flipping mechanism to be pulled out in an orderly manner, so that they can enter the subsequent solder strip pressing mechanism 3 in an orderly manner.

[0084] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be interpreted as limiting the present invention itself.
