Detailed Description of the Embodiments

[0028] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0029] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0030] The following describes a battery cell string soldering tooling 100 according to an embodiment of the present utility model with reference to the accompanying drawings.

[0031] As Figures 1-9 shown, the battery cell string soldering tooling 100 according to an embodiment of the present utility model includes: a frame body 1, a mesh pressing assembly 2, and a middle support rod 3. The mesh pressing assembly 2 is disposed on the frame body 1 and includes a mesh pressing rod 21 and pressing needles 22. The mesh pressing rod 21 extends along a first direction e1 and is provided with a plurality of them arranged in parallel at intervals along a second direction e2. The second direction e2 is perpendicular to the first direction e1. At least part of the plurality of mesh pressing rods 21 is slidably disposed on the frame body 1 along the second direction e2. A plurality of pressing needles 22 are arranged at intervals along the second direction e2 on each mesh pressing rod 21.

[0032] It can be understood that during the string soldering process of the battery cells, the pressing needles 22 can press the solder tape tightly at the welding positions of two adjacent battery cells, thereby avoiding poor welding caused by the offset of the solder tape when two adjacent battery cells are string soldered, so as to improve the firmness of the battery cell welding. However, in different battery cell models, the distance between two adjacent solder joints on the battery cell may be different. Therefore, in the present application, the position of at least part of the mesh pressing rods 21 in the second direction e2 can be adjusted to adjust the distance between the plurality of mesh pressing rods 21 in the second direction e2, so that the distance between the pressing needles 22 on adjacent mesh pressing rods 21 can be adjusted, and thus the requirements for different distances between the solder joints on the battery cell can be met, which is beneficial to expanding the applicable range of the battery cell string soldering tooling 100.

[0033] It should be noted that some of the mesh pressing rods 21 can be slidable relative to the frame body 1 in the second direction e2, or all the mesh pressing rods 21 can be slidable relative to the frame body 1 in the second direction e2. There is no specific limitation here.

[0034] Specifically, when switching battery cells of different sizes, the position of the mesh pressing rods 21 in the second direction e2 can be adjusted so that the pressing needles 22 on two adjacent mesh pressing rods 21 can be aligned with two adjacent solder joints on the battery cell, thereby avoiding poor soldering caused by the mismatch between the pressing needles 22 and the solder joints of the battery cell and improving the firmness of the battery cell soldering.

[0035] In addition, the middle support rod 3 is arranged in the middle of the mesh pressing rods 21 in the first direction e1 and is connected to multiple mesh pressing rods 21. That is to say, the middle positions of multiple mesh pressing rods 21 in the first direction e1 can be fixedly connected to the middle support rod 3. When the middle positions of multiple mesh pressing rods 21 in the first direction e1 are fixedly connected to the middle support rod 3, the distance between any two adjacent mesh pressing rods 21 can be well maintained through the middle support rod 3. Thus, it can be avoided that the distance between two adjacent mesh pressing rods 21 changes due to the deformation of the middle part of the mesh pressing rods 21 in the first direction e1. That is, through the middle support rod 3, the distance between the middle parts of two adjacent mesh pressing rods 21 in the first direction e1 can be maintained at a set distance, where the set distance refers to the distance between two adjacent battery solder joints in the second direction e2, that is, the distance between two adjacent pressing needles 22 in the second direction e2, so as to ensure that the pressing needles 22 on two adjacent mesh pressing rods 21 can accurately align with the corresponding solder joints and improve the reliability of the battery cell series soldering tooling 100.

[0036] In some embodiments, the pressing needles 22 are fixed on the mesh pressing rods 21, thereby avoiding the deviation of the pressing needles 22 from the solder joints of the battery cell due to the relative movement of the pressing needles 22 with respect to the mesh pressing rods 21 and improving the reliability of the pressing needles 22.

[0037] According to the battery cell series soldering tooling 100 of the embodiment of the present invention, the middle support rod 3 is arranged in the middle of the mesh pressing rods 21 in the first direction e1 and is connected to multiple mesh pressing rods 21, which can avoid the change in the distance between two adjacent mesh pressing rods 21 caused by the deformation of the middle part of the mesh pressing rods 21 in the first direction e1. That is, through the middle support rod 3, the distance between the middle parts of two adjacent mesh pressing rods 21 in the first direction e1 can be maintained at a set distance, so as to ensure that the pressing needles 22 on two adjacent mesh pressing rods 21 can accurately align with the corresponding solder joints and improve the reliability of the battery cell series soldering tooling 100.

[0038] According to some embodiments of the utility model, each mesh pressing rod 21 is provided with a first fastener 23, and the first fastener 23 can be switched between a first state and a second state. In the first state, the mesh pressing rod 21 is fixedly connected to the middle support rod 3, and in the second state, the mesh pressing rod 21 is movable relative to the middle support rod 3. That is to say, when it is necessary to adjust the interval between two adjacent mesh pressing rods 21 in the second direction e2, the first fastener 23 on at least one of the mesh pressing rods 21 can be switched to the second state, and the mesh pressing rod 21 can slide freely relative to the middle support rod 3 along the second direction e2, so as to adjust the interval between the two adjacent mesh pressing rods 21. When the interval between the two adjacent mesh pressing rods 21 is adjusted, the first fastener 23 on the mesh pressing rod 21 is switched to the first state, so as to fix the position of the mesh pressing rod 21 on the middle support rod 3, so as to prevent the mesh pressing rod 21 from moving relative to the middle support rod 3, resulting in a change in the interval between the two adjacent mesh pressing rods 21.

[0039] According to some embodiments of the utility model, a first limiting slide groove 31 extending along the second direction e2 is formed on the middle support rod 3, and the first fastener 23 is inserted into the first limiting slide groove 31 and in the second state, the first fastener 23 can slide along the second direction e2 relative to the first limiting slide groove 31. That is, when the first fastener 23 is switched to the second state, the first fastener 23 slides along the second direction e2 relative to the first limiting slide groove 31, and the pressing rod 21 connected to the first fastener 23 is driven to move along the second direction e2 relative to the middle support rod 3, so as to adjust the distance between two adjacent pressing rods 21. Among them, the first limiting slide groove 31 can limit the movement of the first fastener 23 relative to the first limiting slide groove 31 in a direction perpendicular to the second direction e2, thereby avoiding the relative position of the mesh pressing rod 21 and the middle support rod 3 in the direction perpendicular to the second direction e2 from being offset when the position of the mesh pressing rod 21 in the second direction e2 is adjusted, that is, the subsequent connection of the first fastener 23 and the mesh pressing rod 21 for positioning is eliminated, thereby reducing the difficulty of positioning the mesh pressing rod 21 with the middle support rod 3 during the position adjustment process, thereby improving the efficiency of the position adjustment of the mesh pressing rod 21.

[0040] According to some embodiments of the utility model, the middle support rod 3 is located on the side of the pressing rod 21 in the third direction e3 away from the battery cell, wherein the third direction e3 is perpendicular to the first direction e1 and the second direction e2. In other words, the middle support rod 3 and the battery cell are located on opposite sides of the pressing rod 21 in the third direction e3, thereby preventing the middle support rod 3 from contacting the battery cell and affecting the pressing effect of the pressing needle 22 on the battery cell. At the same time, the pressing rod 21 can separate the battery cell from the middle support rod 3, thereby preventing the middle support rod 3 from contacting the battery cell and scratching the battery cell, so as to improve the safety of the battery cell string welding tool 100 and the pressing effect on the battery cell.

[0041] According to some embodiments of the utility model, the first limiting slide groove 31 passes through the middle support rod 3 along the third direction e3. Therefore, the first fastener 23 can be inserted into the first limiting slide groove 31 from the side of the middle support rod 3 away from the mesh pressing rod 21 and connected to the mesh pressing rod 21, thereby simplifying the cooperation between the first fastener 23 and the middle support rod 3 and the mesh pressing rod 21, so as to facilitate the connection between the middle support rod 3 and the mesh pressing rod 21.

[0042] In a specific example, the first fastener 23 is a bolt, and a threaded hole is formed on the side of the mesh pressing rod 21 facing the mesh pressing rod 21 in the third direction e3, and the first fastener 23 is inserted into the first limiting slide groove 31 from the side of the middle support plate away from the mesh pressing rod 21 and is threadedly connected with the mesh pressing rod 21 facing the threaded hole on the mesh pressing rod 21. Therefore, the first fastener 23 can be switched between the first state and the second state by tightening or loosening the first fastener 23, which can well simplify the structure of the first fastener 23, and at the same time, can simplify the difficulty of matching between the first fastener 23 and the middle support rod 3 and the mesh pressing rod 21. Specifically, when it is necessary to adjust the position of the mesh pressing rod 21 relative to the middle support rod 3 in the second direction e2, the first fastener 23 is loosened so that the first fastener 23 can slide in the first limiting slide groove 31 along the second direction e2 for adjustment; after the adjustment is completed, the middle support rod 3 is pressed against the mesh pressing rod 21 by tightening the first fastener 23 to maintain the relative position between the mesh pressing rod 21 and the middle support rod 3.

[0043] According to some embodiments of the utility model, both ends of the pressing rod 21 are provided with a second fastener 24, and the second fastener 24 can be switched between a third state and a fourth state. In the third state, the pressing rod 21 is fixedly connected to the frame 1, and in the fourth state, the pressing rod 21 is movable relative to the frame 1. That is, when it is necessary to adjust the interval between two adjacent pressing rods 21 in the second direction e2, the second fastener 24 on at least one of the pressing rods 21 can be switched to the fourth state, and the pressing rod 21 can slide freely along the second direction e2 relative to the frame 1 to facilitate the adjustment of the interval between the two adjacent pressing rods 21, so that the interval between the pressing pins 22 on the adjacent pressing rods 21 can be adjusted, so that the pressing pins 22 can match the welding points of the battery cell. When the interval between the two adjacent pressing rods 21 is adjusted, the second fastener 24 on the pressing rod 21 is switched to the third state, so as to fix the position of the pressing rod 21 on the frame 1, so as to prevent the pressing rod 21 from moving relative to the frame 1 and causing the interval between the two adjacent pressing rods 21 to change. Therefore, by setting a second fastener 24 on the pressing rod 21 and switching between the third state and the fourth state, it is possible to meet the requirement that the position of the pressing rod 21 relative to the frame 1 can be adjusted while preventing the pressing rod 21 from moving relative to the frame 1 during use to affect the pressing effect on the battery cells.

[0044] According to some embodiments of the present utility model, two second limiting chutes 111 are formed on the frame body 1, which extend along the second direction e2 and are arranged at parallel intervals along the first direction e1. The two ends of the wire pressing rod 21 are respectively arranged in the two second limiting chutes 111 and are slidable relative to the second limiting chutes 111 along the second direction e2. That is to say, when the fastener is switched to the fourth state, the positions of the two ends of the wire pressing rod 21 relative to the corresponding second limiting chutes 111 slide along the second direction e2 to adjust the position of the wire pressing rod 21 relative to the frame body 1 in the second direction e2. Among them, the second limiting chutes 111 can limit the movement of the wire pressing rod 21 relative to the frame body 1 in the direction perpendicular to the second direction e2, so as to avoid the relative position of the wire pressing rod 21 and the frame body 1 in the direction perpendicular to the second direction e2 from shifting when adjusting the position of the wire pressing rod 21 in the second direction e2, that is, the positioning of connecting the frame body 1 and the wire pressing rod 21 is omitted subsequently, and thus the positioning difficulty between the wire pressing rod 21 and the frame body 1 during the position adjustment process of the wire pressing rod 21 can be reduced, and the efficiency of adjusting the position of the wire pressing rod 21 can be improved.

[0045] According to some embodiments of the present utility model, the frame body 1 includes two support seats 11 that are independently formed respectively. The two support seats 11 are arranged at intervals along the first direction e1 on the opposite sides of the wire pressing rod 21. The two second limiting chutes 111 are respectively formed on the two support seats 11, and the second limiting chutes 111 penetrate through the support seats 11 along the first direction e1. The two ends of the wire pressing rod 21 respectively penetrate through the corresponding second limiting chutes 111 along the first direction e1. That is to say, one end of the wire pressing rod 21 is inserted into the second limiting chute 111 of one side of the support seat 11, and the other end of the wire pressing rod 21 is inserted into the limiting chute of the support seat 11 on the other side. By independently forming the two support seats 11 respectively, the difficulty of inserting the wire pressing rod 21 into the second limiting chutes 111 of the two support seats 11 can be reduced. In addition, the second fastener 24 is arranged on the opposite sides of the support seats 11. Thus, sufficient operating space can be provided for the operation of the second fastener 24 to reduce the difficulty of switching the second fastener 24 between the third state and the fourth state.

[0046] In a specific example, the second fastener 24 is a bolt. Threaded holes are formed on both end faces of the wire pressing rod 21 in the first direction e1. After inserting both ends of the wire pressing rod 21 into the second limiting chutes 111 of two supporting seats 11 respectively, two second fasteners 24 can be screwed into the corresponding threaded holes from the opposite sides of the wire pressing rod 21 in the first direction e1. Therefore, by tightening or loosening the second fasteners 24, the switching between the third state and the fourth state of the second fasteners 24 can be achieved, which can preferably simplify the structure of the second fasteners 24 and simplify the matching difficulty between the second fasteners 24, the supporting seats 11 and the wire pressing rod 21. Specifically, when it is necessary to adjust the position of the wire pressing rod 21 relative to the frame body 1 in the second direction e2, the wire pressing rod 21 can be slid along the second direction e2 in the second limiting chute 111 by loosening the second fasteners 24 for adjustment; after the adjustment is completed, the supporting seat 11 is pressed tightly on the wire pressing rod 21 by tightening the second fasteners 24 to maintain the relative position between the wire pressing rod 21 and the supporting seat 11.

[0047] In addition, in the third direction e3, the opposite side surfaces of the part of the wire pressing rod 21 located in the second limiting chute 111 are parallel and in contact with the opposite inner side surfaces of the second limiting chute 111 respectively, so that the wire pressing rod 21 can be prevented from rotating relative to the supporting seat 11 in the first direction e1.

[0048] According to some embodiments of the present utility model, the wire pressing rod 21 includes a main body part 211 and a plug-in part 212. The wire pressing needle 22 is arranged on the main body part 211. Plug-in parts 212 are arranged at both ends of the main body part 211 in the first direction e1. The plug-in parts 212 penetrate through the second limiting chutes 111. A limiting surface 213 is formed between the main body part 211 and the plug-in part 212. The limiting surface 213 abuts against the side surface of the supporting seat 11 facing the main body part 211. That is to say, the movement of the two supporting seats 11 towards the direction of approaching each other can be preferably limited by the limiting surfaces 213 on both sides. Therefore, during the assembly process of the wire pressing rod 21 and the supporting seat 11, the depth of insertion of the wire pressing rod 21 into the second limiting chute 111 can be limited to reduce the assembly difficulty of the solar cell string soldering tooling 100. In addition, the supporting seat 11 can be clamped in cooperation with the second fastener 24 through the limiting surface 213 to fix the position between the supporting seat 11 and the wire pressing rod 21.

[0049] According to some embodiments of the present utility model, the pressing needle 22 includes a connected connecting portion 221 and a pressing portion 222. The connecting portion 221 is connected to the pressing mesh rod 21, and the pressing portion 222 is adapted to contact the battery cell. The side surface of the pressing portion 222 in contact with the battery cell is a pressing surface 2221, and a recessed avoiding groove 2222 is formed on the pressing surface 2221. Therefore, by providing the avoiding groove 2222, the welding points of the battery cell can be avoided, so that the welding points can be prevented from contacting and adhering to the pressing portion 222, and the welding effect can be prevented from being affected when the pressing portion 222 is separated from the battery cell and tearing the welding points.

[0050] In some embodiments, the avoiding groove 2222 has a downwardly open bowl-shaped structure. Thus, the avoiding groove 2222 can preferably avoid the welding points of the battery cell.

[0051] In a specific example, the projection of the pressing portion 222 on the reference plane is larger than the projection of the connecting portion 221 on the reference plane. Thus, the area of the pressing surface 2221 can be preferably increased, and thus the contact area between the pressing portion 222 and the battery cell can be increased to improve the pressing effect of the pressing needle 22 on the battery cell.

[0052] According to some embodiments of the present utility model, the pressing needle 22 is slidably disposed on the pressing mesh rod 21 along the first direction e1. That is to say, the position of the pressing needle 22 relative to the pressing mesh rod 21 in the first direction e1 is adjustable. Therefore, the distance between two adjacent pressing needles 22 in the first direction e1 can be adjusted by adjusting the position of the pressing needle 22 in the first direction e1 to meet the requirements of different distances between two adjacent welding points in the first direction e1.

[0053] According to some embodiments of the present utility model, an installation groove 112 is provided on the lower surface of the frame body 1, and a detachable anti-slip cushion block 12 is provided in the installation groove 112. Among them, the anti-slip cushion block 12 can increase the friction between the battery cell string soldering tooling 100 and the soldering station, and avoid the pressing needle 22 from shifting due to the sliding of the frame body 1 when transporting the battery cell. At the same time, the anti-slip cushion block 12 is detachable and can be replaced when the anti-slip cushion block 12 is worn out excessively to ensure the anti-slip effect of the anti-slip cushion block 12.

For example, it can be a fixed connection, a detachable connection, or an integral body; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components.
