Description

Technical Field

[0001] This application relates to the technical fields of solar cell technology and battery string soldering technology, and particularly relates to a battery string flattening device and a soldering equipment. Background Art

[0002] In a photovoltaic module, multiple solar cells need to be soldered in series to achieve high voltage output. During the soldering process of the solar cells, multiple solar cells are first soldered into a battery string; then multiple battery strings are soldered to obtain a photovoltaic module.

[0003] During the process of soldering multiple solar cells into a battery string, due to the excessively high soldering temperature, the solder tape bends after soldering is completed, which in turn causes the battery string to warp. When the warping angle of the battery string is too large, the solar cells are squeezed during the lamination of the photovoltaic module, and fragments are likely to occur, reducing the qualification rate of the photovoltaic module.

[0032] Next, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments described herein.

[0033] An embodiment of the present application provides a battery string flattening device for flattening a battery string, and in particular, can flatten a warped position.

[0034] As Figure 1 shown, the battery string flattening device provided by the embodiment of the present application includes an adsorption unit, a pressing unit, and a support unit.

[0035] The adsorption unit can adsorb the battery string. The adsorption unit includes a base 22 and a plurality of suction cups 26; a plurality of suction cup seats 26 for fixing the suction cups 26 are provided on the base 22, so that the plurality of suction cups 26 are arranged on the base 22 according to a preset rule, and the suction cups 26 are connected to a negative pressure device.

[0036] The suction cup seat 26 can be a through hole for the suction cup 26 to pass through, so that the suction cup 26 can penetrate the base 22.

[0037] The suction cup seat 26 can also include a through hole penetrating the base 22, and the edge of the through hole is set to a structure adapted to the outer shape of the suction cup 26, so that the suction cup 26 is firmly fixed on the suction cup seat 26, ensuring the stability of adsorbing the battery string, and thus ensuring the flattening effect.

[0038] The suction cup 26 can be a plastic part or a metal part. Preferably, a material that can adsorb the battery cell more firmly can be selected to ensure the stability of adsorption.

[0039] The suction cup 26 can be connected to the negative pressure device through a pipeline 17; the pipeline 17 and the adsorption position of the suction cup 26 are respectively located on opposite sides of the base 22.

[0040] In one example, the base 22 may be a non-solid structure, such as a hollow box-shaped structure, and a through hole is provided at a preset position for arranging the suction cup 26 at the through hole. The side wall of the through hole may be a connected plate-shaped structure; the side wall of the through hole may also be a disconnected structure, and the side wall is connected to the hollow box-shaped structure.

[0041] In one example, the base 22 may also be a sheet-like structure.

[0042] In one example, the adsorption unit can also be a plurality of suction cups 26 arranged according to preset rules, and the plurality of suction cups 26 are connected and fixed by connecting rods to obtain a stable structure capable of maintaining the plurality of suction cups 26 arranged according to preset rules. The plurality of connecting rods form the base 22 of the adsorption unit.

[0043] The pressing unit includes a flexible member 25 . The flexible member 25 is fixed in the gaps between the plurality of suction cups 26 on the base 22 . The flexible member 25 protrudes from the suction cups 26 .

[0044] The flexible member 25 is fixed to the gaps between the multiple suction cups 26 on the base 22, and can be passed through the gaps between the multiple suction cups 26, or can be respectively set at the gaps between the multiple suction cups 26. The flexible member 25 is set to protrude from the suction cup 26, so that the flexible member 25 can abut against the battery string. The flexible member 25 is a member with a certain elasticity, which can provide a thrust for the battery string away from the base 22. The height of the flexible member 25 protruding from the suction cup 26 can be adapted to the elastic coefficient of the flexible member 25. The smaller the elastic coefficient of the flexible member 25, the higher the height protruding from the suction cup 26 can be.

[0045] The flexible member 25 is disposed in the gaps between the plurality of suction cups 26 , so that a plurality of locations in the battery string can abut against the flexible member 25 .

[0046] In the embodiment of the present application, the adsorption unit provides suction force toward the base 22 for the adsorbed battery string; the flexible member 25 protrudes from the suction cup 26 so that the flexible member 25 abuts against the battery string. Under the adsorption action of the suction cup 26, the battery string has a tendency to continuously move toward the base 22. When the battery string is warped (warped toward the base 22), the flexible member 25 is squeezed and thus subjected to a greater thrust from the flexible member 25, causing the warped position to bulge in a direction away from the base 22 until the adsorption force and the thrust are balanced. In this state, the battery string is flat, and the thrust / suction forces received at multiple locations of the battery string are equal or approximately equal.

[0047] Under the adsorption of the suction cups 26, the battery string has a tendency to continuously move towards the base 22. If the warped position of the battery string warps away from the base 22, the warped position will protrude towards the base 22 based on the adsorption force of the suction cups 26, so that the battery string reaches a flat state.

[0048] The support unit includes a support member 24, and the support member 24 is fixedly connected to the base 22. The support unit plays a role in supporting the base 22, and the support member 24 can drive the base 22 or the adsorption unit close to the battery string to implement the adsorption of the battery string.

[0049] In the embodiment of the present application, the suction force of the suction cups 26 adsorbing the battery string and the thrust formed by the flexible member 25 protruding from the suction cups 26 act on the battery string together to smooth the warped part of the battery string, so that the battery string reaches a flat state and improves the qualification rate of the photovoltaic module. At the same time, the battery string flattening device in the embodiment of the present application can also adsorb the battery string to facilitate moving the battery string to different positions, such as moving to the next process, and improve the production efficiency of the photovoltaic module.

[0050] In one implementation, the battery string is formed by string welding a plurality of battery cells; the preset rules include: the distance between the plurality of suction cups 26 is adapted to the size of the battery cells, and at least two suction cups 26 are provided corresponding to one battery cell.

[0051] The distance between the plurality of suction cups 26 is adapted to the size of the battery cells, so that each battery cell is correspondingly provided with a suction cup 26, and each battery cell is subjected to an adsorption force. Thus, if any part of a battery cell warps, there is a chance to be smoothed by the flexible member 25 between the suction cups 26.

[0052] At least two suction cups 26 are provided corresponding to one battery cell, so that at least two positions on one battery cell are subjected to an adsorption force, the force is more stable, and the force is stronger, which is more convenient to counteract with the flexible member 25, so that the flexible member 25 smooths the warped position.

[0053] In one implementation, the preset rules further include: the number of suction cups 26 corresponding to the plurality of battery cells is the same.

[0054] The number of suction cups 26 corresponding to the plurality of battery cells is the same, so that the adsorption forces received by the plurality of battery cells are the same. Thus, the effect of the flexible member 25 smoothing each part is the same; it avoids the situation that due to the small adsorption force received by another battery cell, the flexible member 25 does not have enough thrust acting on the warped position, resulting in uneven smoothing results.

[0055] In one example, among multiple solar cells, each solar cell corresponds to two suction cups 26, and the multiple suction cups 26 can be arranged in a row; in a row of suction cups 26, every two suction cups 26 hold one solar cell; the multiple suction cups 26 can also be arranged in two rows, and in the two rows of suction cups 26, two opposite suction cups 26 hold one solar cell; the two opposite suction cups 26 can be directly opposite or diagonally opposite, and in the case of diagonal opposition, the two suction cups 26 can respectively hold two positions on the diagonal of the solar cell.

[0056] In one example, the adsorption unit can also adsorb multiple strings of solar cell strings simultaneously; for example, each row of suction cups 26 adsorbs one string of solar cell strings; or every two rows of suction cups 26 adsorb one string of solar cell strings. By adsorbing multiple strings of solar cell strings simultaneously with the adsorption unit, it is also possible to simultaneously adsorb multiple strings of solar cell strings to be string-soldered, and after being smoothed by the flexible member 25, move the multiple strings of solar cell strings to the next process for string soldering simultaneously, further improving the processing efficiency of the photovoltaic module. Based on the arrangement of the multiple suction cups 26 of the adsorption unit according to a preset rule, it is also possible to make the multiple strings of solar cell strings adsorbed arranged neatly according to a second preset rule to meet the arrangement requirements of the solar cell strings during string soldering, further improving the processing efficiency of the photovoltaic module.

[0057] In one implementation, the number of flexible members 25 is multiple, and the multiple flexible members 25 are fixed in multiple gaps between the multiple suction cups 26 on the base 22.

[0058] In the embodiments of the present application, the number of flexible members 25 is multiple, and the flexible members 25 at different gaps are independent, and the different heights, different materials or different connection methods of the flexible members 25 can be adjusted according to the acting forces at different positions.

[0059] In one example, the gaps between the multiple suction cups 26 on the base 22 where the multiple flexible members 25 are fixed can be such that the height of the outer flexible member 25 is lower than the height of the inner flexible member 25, so that the outer side of the solar cell string receives a relatively greater adsorption force to ensure the flatness effect after the solar cell string is smoothed.

[0060] In some other examples, the flexible member 25 can also be an integral block with a through hole in the middle for sleeving on the suction cup 26 seat.

[0061] In one implementation, the multiple flexible members 25 are fixedly connected and / or detachably connected to the base 22, and the detachable connection includes bonding.

[0062] The multiple or multiple flexible members 25 can be fixedly connected to the base 22, or can be detachably connected, such as by bonding; or some can be fixedly connected and some can be detachably connected.

[0063] When the flexible member 25 is detachably connected to the base 22, the flexible member 25 can be removed according to the actual application situation.

[0064] In one embodiment, the flexible member 25 located outside the plurality of suction cups 26 is detachably connected to the base 22.

[0065] Located outside the plurality of suction cups 26 can be any one or more of the outer sides around the plurality of suction cups 26.

[0066] The flexible member 25 located outside the plurality of suction cups 26 is detachably connected to the base 22, so that the flexible member 25 outside can be removed, so that the outer side of the battery string is more affected by the adsorption force of the suction cups 26, and the battery string abuts against the suction cups 26.

[0067] In one example, when the outer side of the battery string warps away from the base 22 more, the flexible member 25 outside the plurality of suction cups 26 can be removed to pull the battery string towards the base 22 by the adsorption of the suction cups 26.

[0068] In one embodiment, the flexible member 25 is a sponge block or a sponge strip.

[0069] The sponge block or the sponge strip is elastic and can gently flatten the battery string, avoiding the situation where the battery string is flattened by the flexible member 25 that is too large or too rigid, resulting in battery chip breakage, thereby further protecting the qualification rate of the photovoltaic module.

[0070] In one embodiment, it further includes a flattening platform 23, and the flattening platform 23 is used to carry the battery string to be flattened.

[0071] The battery string to be flattened is placed on the flattening platform 23. It can be that the battery string is manually placed on the flattening platform 23; it can also be that the mechanical transmission mechanism conveys the battery string to the flattening platform 23.

[0072] The adsorption unit can be arranged above the flattening platform 23 to facilitate accurate adsorption of the battery string. Other positioning devices can also be provided on the flattening platform 23 to facilitate the adsorption unit to adsorb the battery string more quickly and accurately based on the positioning signal.

[0073] The embodiment of the present application also provides a string welding device, as Figure 2 shown, including: a welding device and the battery string flattening device according to any one of the above embodiments.

[0074] The welding device is used for performing the string welding operation of the battery string. The welding device includes a string welding platform 12, and the string welding platform 12 is used to carry the battery string to be string welded.

[0075] The battery string flattening device is used to flatten the battery string to be string-soldered. The battery string flattening device further includes a moving unit. The moving unit includes a connecting rod 21 and a power mechanism for driving the movement of the connecting rod 21. The first end of the connecting rod 21 is fixedly connected to a support member 24. When the power mechanism drives the connecting rod 21 to move, the support member 24 is driven to move, so as to place the battery string adsorbed by a plurality of suction cups 26 onto the string-soldering platform 12.

[0076] In the embodiment of the present application, by moving the support member 24 through the moving unit, the movement of the battery string can be realized, and during the movement process, the flattening operation of the battery string is realized, saving the time for additional flattening operations.

[0077] In one example, the moving speed can be set according to the moving distance and the time required to flatten the battery string; to ensure that the flattening of the battery string is completed during the movement to the string-soldering platform 12.

[0078] In one implementation manner, the string-soldering device further includes a truss; the power mechanism includes: a first lead screw 16, a first moving block sleeved on the first lead screw 16, and a first power member 20 for driving the movement of the first lead screw 16. The first moving block is fixedly connected to the second end of the connecting rod 21; the first lead screw 16 is fixed on the cross beam of the truss.

[0079] The truss is a structure including vertical rods 2 and a cross beam. Two or more vertical rods 2 support the cross beam and are fixed. The vertical rods 2 can be fixed to the ground or can be fixed to the bottom plate 1, so that the entire string-soldering device forms an integral body with the bottom plate 1, facilitating the movement and handling of the string-soldering device.

[0080] In the embodiment of the present application, the adsorption unit is located above the flattening platform 23, and it is necessary to adsorb the battery string away from the flattening platform 23. The path for the moving mechanism to drive the battery string to move is preferably set above the flattening platform 23. Therefore, by arranging the first lead screw 16 on the truss, stable and slow movement of the battery string can be realized based on the transmission of the first lead screw 16. Since it takes time to flatten the battery string, the speed of moving the battery string does not need to be too fast.

[0081] The first power member 20 drives the first lead screw 16 to rotate. The rotation of the first lead screw 16 drives the first moving block to move along the direction of the first lead screw 16. The first moving block is fixedly connected to the second end of the connecting rod 21, and the first end of the connecting rod 21 is fixedly connected to the support member 24. The support member 24 supports the adsorption unit, and the adsorption unit adsorbs the battery string. Therefore, the movement of the first moving block can drive the battery string adsorbed by the adsorption unit to move. By setting the string-soldering platform 12 at a specified position, the first moving block can move the battery string to the specified string-soldering platform 12.

[0082] In one example, such as Figure 3As shown, the first moving block may include a threaded sleeve 27 sleeved on the first lead screw 16, a fixed sleeve 29 sleeved on the second end of the connecting rod 21, and a first connecting seat 30 connecting the threaded sleeve 27 and the fixed sleeve 29. The threaded sleeve 27 is used to cooperate with the first lead screw 16 so that when the first lead screw 16 rotates, the threaded sleeve 27 can move; the fixed sleeve 29 is used to be fixedly sleeved on the connecting rod 21.

[0083] In one example, the fixed sleeve 29 can also be movably sleeved on the connecting rod 21 to adjust the distance from the first end to the second end of the connecting rod 21, that is, to adjust the distance between the threaded sleeve 27 and the adsorption unit, which is convenient for making adaptive adjustments according to the position of the string welding platform 12 to more accurately move the battery string to the string welding platform 12.

[0084] In one implementation, the welding device includes: a welding head unit, a second lead screw 7, a second moving block 6 sleeved on the second lead screw 7, and a second power member 4 driving the second lead screw 7 to move. The welding head unit is fixed to the second moving block 6; the second lead screw 7 is fixed to the cross beam of the truss; the connection line between the string welding platform 12 and the flattening platform 23 is parallel to the cross beam; the length of the first lead screw 16 is adapted to the distance from the string welding platform 12 to the flattening platform 23.

[0085] By fixing the second lead screw 7 and the first lead screw 16 to the same truss together, the structure of the string welding device is made compact, the number of vertical poles 2 is reduced, the string welding operation is convenient and intuitive, and the path for the battery string flattening device to drive the battery string to move is also convenient. Among them, the first lead screw 16 and the second lead screw 7 are independent of each other. A first outer shell covering the first lead screw 16 can be provided at the first lead screw 16. The first outer shell can include an upper frame 15 and a lower frame 28 to limit the movement of the first moving block. A second outer shell 5 covering the second lead screw 7 can be provided at the second lead screw 7 to limit the movement of the second moving block 6.

[0086] The connection line between the string welding platform 12 and the flattening platform 23 is parallel to the cross beam. In the actual application process, being parallel or approximately parallel is within the protection scope of the embodiments of the present application. The connection line between the string welding platform 12 and the flattening platform 23 being parallel to the cross beam can facilitate the connecting rod 21 to drive the adsorption unit to linearly move to the string welding platform 12.

[0087] In one implementation, a plurality of battery string flattening devices are correspondingly provided for one welding device so that the plurality of battery string flattening devices sequentially place the battery strings onto the string welding platform 12 in sequence.

[0088] As described above, it takes some time to flatten the battery string, so it is not necessary to move the battery string to the string soldering platform 12 too quickly. The string soldering between battery strings is relatively fast. Therefore, by arranging one soldering device corresponding to multiple battery string flattening devices, multiple flattening devices can move the battery strings to the string soldering platform 12 in sequence, which can improve the string soldering efficiency.

[0089] In one embodiment, a plurality of second moving blocks 6 are arranged on one second lead screw 7, and one soldering head unit is fixed to one second moving block 6.

[0090] Arranging a plurality of soldering head units on one second lead screw 7 enables soldering to be performed synchronously from different positions of the battery string, further improving the string soldering efficiency.

[0091] The soldering head unit includes a second connecting seat 8, a soldering head bracket 9, a soldering head 11, and a cylinder 10. The soldering head bracket 9 is used to fix the soldering head 11 and the cylinder 10; the second connecting seat 8 is used to fixedly connect the second moving block 6 and the soldering head bracket 9.

[0092] In the embodiment of the present application, the string soldering device further includes a control device 3 to control the first power member 20, the second power member 4, and / or the cylinder 10.

[0093] In one example, the string soldering device further includes a lighting unit for providing a light source for the soldering process of the soldering device or the adsorption process of the battery string flattening device, so as to facilitate the monitoring device to take pictures of the battery string and detect the battery string, further ensuring the qualification rate of the battery string or the photovoltaic module.

[0094] The lighting unit includes a gooseneck tube 14 and a light source emitting device 13. The light source emitting device 13 can be an LED (Lighting Emitting Diode) lamp. The gooseneck tube 14 is used to fix the light source emitting device 13 to the string soldering platform 12 and / or the flattening platform 23.

[0095] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0096] For ease of description, the orientation or positional relationship indicated by orientation terms such as "front, rear, top, bottom, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description. Without contrary explanation, these orientation terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present application; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "on top of other devices or structures" will then be positioned as "below other devices or structures" or "beneath other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the relative spatial descriptions used here.

[0097] Unless otherwise clearly specified and defined, terms such as "mounted", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or a communication connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of two elements or the interaction relationship between two elements.
