Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component processing, in particular to a welding strip preparation device. Background Art

[0002] In the production process of photovoltaic modules, adjacent cells need to be connected by welding ribbons to form a cell string of a certain size. In the process of forming IBC cell strings, the welding ribbon is only located on the surface of one side of the cell, and the welding ribbon on the cell in the middle position needs to extend to the ends of the cell on both sides. In the traditional forming process, a longer welding ribbon group is usually pulled out at one time, and then cut and divided to form the required welding ribbon group, but the overall process of this method is relatively cumbersome and is not conducive to high-speed preparation of cell strings.

[0003] Currently, a method of preparing battery strings following the flow of battery cells is provided, which can meet the needs of high-speed preparation of battery strings. However, in this method, since the directions of the welding ribbon groups extending to both sides of the same battery cell are different, the welding ribbons are arranged in a staggered manner on the battery string assembly from an overall perspective. If two sets of welding ribbon making mechanisms are used, the handling and making operations are cumbersome and will lead to an increase in the cost of preparation. If one set of mechanisms is used for preparation, how to make staggered welding ribbon groups of different quantities becomes a problem that needs to be solved urgently. Utility Model Content

[0039] The following example is a device for preparing a welding strip of the utility model. This example is only a part of the embodiments of the utility model, but the protection scope of the utility model is not limited to this. All other embodiments obtained by ordinary technicians in this field without creative work should be included in the protection scope of the utility model.

[0040] Please refer to Figures 1 to 8 According to an embodiment of the present invention, a welding strip preparation device is provided, specifically referring to Figure 1 and Figure 2 As shown, the welding ribbon preparation device includes a stand 102, on which a welding ribbon 100 is pulled out (in the direction of Figure 1The orientation shown is for reference, that is, from the upper right to the lower left in the figure), there are a welding ribbon holding mechanism, a welding ribbon cutting mechanism 3, and a ribbon pulling hand 4 arranged in sequence. It can be understood that the aforementioned welding ribbon holding mechanism includes a first welding ribbon holding mechanism 1 and a second welding ribbon holding mechanism 2, and the second welding ribbon holding mechanism 2 is located between the first welding ribbon holding mechanism 1 and the welding ribbon cutting mechanism 3. The first welding ribbon holding mechanism 1 and the second welding ribbon holding mechanism 2 can effectively hold each welding ribbon 100 passing therethrough, and the ribbon pulling hand 4 can clamp the free ends of each welding ribbon 100 supported on the welding ribbon roller 101 and pull out a preset length, thereby forming a welding ribbon segment under the cutting of the aforementioned welding ribbon cutting mechanism 3. Specifically, the second welding ribbon holding mechanism 2 is adjacent to the welding ribbon cutting mechanism 3. The first welding tape pressing mechanism 1 is configured to be controlled to move a certain distance toward one side of the first welding tape holding mechanism 1 when the ribbon pulling hand 4 moves close to it to clamp the free end of each welding tape 100, and the first welding tape holding mechanism 1 maintains the pressing of each welding tape 100 during the process, that is, to ensure that the position of the free end of each welding tape 100 is fixed, and also includes a welding tape connecting platform 5 for receiving the welding tape segment formed by cutting by the welding tape cutting mechanism 3, and the welding tape connecting platform 5 can be specifically formed with welding tape grooves (not marked in the figure) corresponding to each welding tape segment, and each welding tape groove is preferably provided with a corresponding vacuum adsorption hole to ensure that the welding tape segment of the cut arc can be stably and reliably located on the welding tape connecting platform 5, and the first welding tape holding mechanism 1 and / or the second welding tape holding mechanism 2 have a first pressing state and The second pressing state, in the first pressing state, each pressing column 21 of the second solder strip pressing mechanism 2 can press each solder strip 100 thereunder, in the second pressing state, a part of each pressing column 21 of the second solder strip pressing mechanism 2 can press each solder strip 100 thereunder, and the remaining part releases the pressure on each solder strip 100 thereunder, the strap hand 4 has a first clamping state and a second clamping state, in the first clamping state, each chuck 41 of the strap hand 4 clamps each solder strip 100 thereunder, in the second clamping state, a part of each chuck 41 of the strap hand 4 can clamp each solder strip 100 thereunder, and the remaining part releases the pressure on each solder strip 100 thereunder 100 clamping, the number of pressure columns 21 of the second welding strip pressing mechanism 2 is equal to the number of chucks 41 of the strap hand 4, the number of each pressure column 21 that is not in the pressing state in the second pressing state is equal to the number of each chuck 41 in the clamping state in the second clamping state, and the positions correspond one to one, that is, the first pressing state of the second welding strip pressing mechanism 2 corresponds to the first clamping state of the strap hand 4, and the second pressing state of the second welding strip pressing mechanism 2 corresponds to the second clamping state of the strap hand 4. It can be understood that by controlling the state switching of the aforementioned second welding strip pressing mechanism 2 and the strap hand 4, the preparation of different numbers of welding strips can be achieved, and the first welding strip pressing mechanism 1 and the second welding strip pressing mechanism 2 are both in a non-pressing state.That is, the state in which the entire welding ribbon 100 is allowed to pass therethrough, and the strap puller 4 is in a non-clamping state, that is, the clamp 41 thereof does not clamp the free end of the welding ribbon 100.

[0041] In this technical solution, the second welding strip pressing mechanism 2 has a first pressing state and a second pressing state that can be controlled to switch, and the number of pressed welding strips 100 is different in the two states, and the strap hand 4 has a first clamping state and a second clamping state that can be controlled to switch, and the number of clamped welding strips 100 is different in the two states. At the same time, the states of the second welding strip pressing mechanism 2 and the strap hand 4 correspond to each other, thereby realizing the preparation of welding strip groups with different numbers (quantities), thereby meeting the requirements of the IBC battery string forming process for welding strips, simplifying the process steps and reducing the cost of welding strip preparation.

[0042] Specifically, taking the example of 10 and 9 welding ribbons 100 in the IBC battery string arranged in an alternating manner, the second welding ribbon pressing mechanism 2 has 10 pressing columns 21 and the strap hand 4 has 10 clamps 41. When the second welding ribbon pressing mechanism 2 is in a first pressing state, all 10 pressing columns 21 are driven downward to press the 10 welding ribbons 100. When it is in the second pressing state, only one pressing column 21 is driven downward to press one welding ribbon 100, and the other 9 welding ribbons 100 can pass freely therethrough. For the strap hand 4, when it is in the first clamping state, all 10 clamps 41 are driven to clamp the free ends of the 10 welding ribbons 100. When it is in the second clamping state, 9 clamps 41 are driven to clamp the free end of one welding ribbon 100. When preparing a weld ribbon group consisting of 10 weld ribbons 100, the ribbon pulling hand 4 is controlled to be in the first clamping state, and the second weld ribbon holding mechanism 2 and the first weld ribbon holding mechanism 1 are all in the non-holding state. When preparing a weld ribbon group consisting of 9 weld ribbons 100, the ribbon pulling hand 4 is controlled to be in the second clamping state, and the second weld ribbon holding mechanism 2 is in the second holding state, and the first weld ribbon holding mechanism 1 is in the non-holding state. It can be understood that when the ribbon pulling hand 4 is clamping the free end of the weld ribbon 100, the first weld ribbon holding mechanism 1 should be in the holding state, and the second weld ribbon holding mechanism 2 needs to be controlled accordingly according to the state of the ribbon pulling hand 4. For example, when the ribbon pulling hand 4 is in the second clamping state, the second weld ribbon holding mechanism 2 is in the second holding state. When the weld ribbon cutting mechanism 3 is cutting, the second weld ribbon holding mechanism 2 is controlled to be in the first holding state.

[0043] See also Figure 5 and Figure 6As shown, in some embodiments, the second solder strip pressing mechanism 2 includes: a pressure column mounting substrate 22, on which a first pressing air cavity 221 and a second pressing air cavity 222 are formed, wherein the first pressing air cavity 221 has a first pressing deformation diaphragm on the side facing the solder strip 100, and the second pressing air cavity 222 has a second pressing deformation diaphragm on the side facing the solder strip 100, and the first number of the pressure columns 21 are arranged corresponding to the first pressing deformation diaphragm, so that when the pressure fluid is introduced into the first pressing air cavity 221, the pressure fluid is passed through the pressure column 221. The first pressure-holding deformable diaphragm synchronously drives the corresponding pressure columns 21 to press the welding strip 100. The second number of pressure columns 21 are correspondingly arranged to the second pressure-holding deformable diaphragm, so that when the pressure fluid is introduced into the second pressure-holding air cavity 222, the corresponding pressure columns 21 are synchronously driven by the second pressure-holding deformable diaphragm to press the welding strip 100. The aforementioned first number is, for example, 9, and the second number is, for example, 1, to adapt to the working conditions of 10 and 9 welding strips 100 mentioned above. The aforementioned first pressure-holding deformable diaphragm and the second pressure-holding deformable diaphragm can specifically adopt silicone diaphragms.

[0044] In this technical solution, by setting the first pressure-holding air cavity 221 and the second pressure-holding air cavity 222 on the pressure column mounting substrate 22, the state switching of different pressure columns 21 can be selectively controlled. Through the corresponding setting of the air cavity and the pressure-holding deformation diaphragm, there is no need to independently set driving components for each pressure column 21, thereby simplifying the structural design and reducing manufacturing costs.

[0045] In order to be able to perform necessary maintenance operations at the pressing position corresponding to the welding strip 100, in a preferred embodiment, a plurality of manual valves 23 are also provided on the pressure column mounting substrate 22, and each of the manual valves 23 is respectively provided corresponding to each of the pressure columns 21. By controlling the on and off of the manual valves 23, the application and release of the downward pressure on different pressure columns 21 can be achieved.

[0046] In a preferred embodiment, the first welding strip pressing mechanism 1 and the second welding strip pressing mechanism 2 have the same structure, so as to further reduce the overall manufacturing cost of the device. It should be noted that the aforementioned first welding strip pressing mechanism 1 and the second welding strip pressing mechanism 2 are structurally identical, which means that the first welding strip pressing mechanism 1 also has the aforementioned first pressing state and second pressing state, but this does not mean that it must have the switching action between the first pressing state and the second pressing state during use. In fact, the first welding strip holding mechanism 1 can achieve the purpose of preparing different numbers of welding strips in this application by only using its first pressing state and non-pressing state.

[0047] See also Figure 7 and Figure 8As shown, in some embodiments, the strap puller 4 includes: a clamping jaw mounting substrate 42, on which a first clamping air cavity 421 and a second clamping air cavity 422 are formed, wherein the first clamping air cavity 421 has a first clamping deformable diaphragm 423 on the side facing the welding strip 100, and the second clamping air cavity 422 has a second clamping deformable diaphragm 424 on the side facing the welding strip 100, a first number of the clamps 41 are correspondingly arranged with the first clamping deformable diaphragm 423, so that when a pressure fluid is introduced into the first clamping air cavity 421, the first clamping deformable diaphragm synchronously drives each correspondingly arranged clamp 41 to clamp the welding strip 100, and a second number of the clamps 41 are correspondingly arranged with the second clamping deformable diaphragm 424, so that when a pressure fluid is introduced into the first clamping air cavity 421, the first clamping deformable diaphragm is synchronously driven to clamp the welding strip 100, and a second number of the clamps 41 are correspondingly arranged with the second clamping deformable diaphragm 424. When the pressure fluid is introduced into the second clamping air cavity 422, the second clamping deformable diaphragm 424 synchronously drives the corresponding clamps 41 to clamp the welding strip 100. It should be noted that the switching of the aforementioned pressure columns 21 from the clamping state to the non-clamping state can rely on the corresponding springs. Similarly, the switching of the clamps 41 from the clamping state to the non-clamping state can also rely on the corresponding springs, such as the spring 44 shown in the figure. Specifically, each clamp 41 is detachably connected to the first end of the arm 45, and the first end of the arm 44 and the clamping jaw mounting base plate 42 clamp the aforementioned spring 44, and the second end of the arm 45 contacts the aforementioned first clamping deformable diaphragm 423 or the second clamping deformable diaphragm 424, and the middle position of the arm 45 is hinged to the clamping jaw mounting base plate 42. The clamping of the welding strip 100 is achieved by the joint action of the clamp 41 and the clamping plate 43 under the clamping jaw mounting base plate 42. The first clamping deformable diaphragm 423 and the second clamping deformable diaphragm 424 may be specifically made of silicone diaphragms.

[0048] In this technical solution, by setting the first clamping air cavity 421 and the second clamping air cavity 422 on the clamping jaw mounting substrate 42, the state switching of different clamps 41 can be selectively controlled. Through the corresponding setting of the air cavity and the clamping deformation diaphragm, there is no need to independently set a driving component for each clamp 41, thereby simplifying the structural design and reducing the manufacturing cost.

[0049] It can be understood that the first pressing and holding air cavity 221 , the second pressing and holding air cavity 222 , the first clamping air cavity 421 and the second clamping air cavity 422 are all controllably connected to corresponding pressure fluid sources, and the pressure fluids are, for example, pressurized air.

[0050] In some embodiments, the first pressure-holding deformable diaphragm and the second pressure-holding deformable diaphragm are integrally formed; and / or the first clamping deformable diaphragm 423 and the second clamping deformable diaphragm 424 are integrally formed, which can simplify the number of assembled parts and thus simplify the assembly of the device.

[0051] In a preferred embodiment, the second solder ribbon pressing mechanism 2 and the solder ribbon cutting mechanism 3 are both assembled on a mounting base 61, and the mounting base 61 can be driven to move closer to or away from the first solder ribbon pressing mechanism 1, so that when the ribbon pulling hand 4 needs to clamp the free end of each solder ribbon 100, the second solder ribbon pressing mechanism 2 and the solder ribbon cutting mechanism 3 can be controlled to retreat synchronously and keep the relative position of the second solder ribbon pressing mechanism 2 and the solder ribbon cutting mechanism 3 stable.

[0052] See also Figures 2 to 4 As shown, in some embodiments, the welding ribbon cutting mechanism 3 includes: an upper cutting knife 31, which can be driven to rise and fall (for example, a corresponding lifting cylinder or other driving components), and realizes the cutting function of the welding ribbon 100 during the process of being lowered; see Figure 4 As shown, the solder strip lead-in plate 32 is located below the upper cutting knife 31, and the solder strip lead-out side (with Figure 4 The orientation reference shown, that is, the left side of the solder strip threading plate 32, has a lower cutting knife 321, and the outer side of the lower cutting knife 321 has a bevel, which makes the thickness of the lower cutting knife 321 gradually increase along the descending direction of the upper cutting knife 31, and the cutting edge of the upper cutting knife 31 can abut against the bevel during the cutting process of the solder strip 100.

[0053] In this technical solution, by setting a slope on the outer side of the lower cutting knife 321, the descending cutting process of the upper cutting knife 31 can be guided. When the upper cutting knife 31 and the lower cutting knife 321 are performing the shearing action, they will form contact in front of the cutting position, and according to further actions, the upper cutting knife 31 and the lower cutting knife 321 will form a certain resistance. Through the elastic action, it is ensured that there is no gap between the upper cutting knife 31 and the lower cutting knife 321, which has better shearing force and achieves smoother cutting.

[0054] In some embodiments, the solder strip cutting mechanism 3 further includes a lifting plate body 33, the side of the lifting plate body 33 corresponding to the solder strip lead-out side of the solder strip lead-in plate 32 is a first side surface, the upper cutting knife 31 is connected to the first side surface, and the first side surface is also connected to an anti-deviation plate 34, the anti-deviation plate 34 is located on the side of the upper cutting knife 31 away from the lower cutting knife 321, and the bottom side of the anti-deviation plate 34 has a plurality of limit slots 341 that can be one-to-one covered outside each of the solder strips 100, see Figure 3 As shown, in a specific embodiment, the limiting groove 341 is V-shaped, and when the upper cutting knife 31 is lowered to the lowest position, there is a gap between the limiting groove 341 and the welding strip 100 covered therein, thereby preventing the welding strips 100 from shifting in position after cutting.

[0055] See again Figure 1 As shown, the tape connecting platform 5 has two groups, and the two groups of tape connecting platforms 5 are cyclically and alternately located below the solder tape 100 between the tape pulling hand 4 and the solder tape cutting mechanism 3. Each tape connecting platform 5 can be raised and lowered to connect the solder tape group to be cut, and complete the adsorption of the solder tape group after cutting. When one group is transported to the rear end, the empty tape connecting platform 5 at the rear end moves to the front end to adsorb the solder tape group again.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
