[0002] With the development of photovoltaic technology, in order to improve the power conversion efficiency of solar cells, multiple solar cells are stacked on top of each other and welded together by welding tapes to form a battery string.

[0003] In the prior art, in order to ensure good contact between the welding tape and the solar cell for subsequent welding, generally, after the welding tape is carefully laid on the carrier, the solar cell is placed on the welding tape, and a complex negative pressure system on the carrier applies an adsorption force to the solar cell to maintain its close fit with the welding tape. Although such methods are effective, they inevitably introduce new problems, resulting in a large number of evenly distributed negative pressure holes densely arranged on the carrier, which not only greatly increases the structural complexity of the carrier, but also makes its processing difficulty and subsequent maintenance cost soar, becoming a key factor restricting production efficiency and cost control.

[0038] The embodiment of the present application provides a processing device, which solves the technical problem of how to simplify the structure of the carrier 100 and achieves the technical effect of improving the simplification of the structure of the carrier 100.

[0039] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] The embodiment of the present application provides a processing device for processing battery wafers and solder tapes, as Figure 1 shown, which includes a carrier 100 and a holding assembly 200. The carrier 100 is used as the laying basis for battery wafers and / or solder tapes, and the holding assembly 200 is used to press the battery wafer onto the carrier 100 so that the battery wafer is stably fixed on the carrier 100.

[0041] Specifically, as Figure 1 、 2 shown, the carrier 100 has a first surface 110, and the solder tape and the battery wafer are laid on the first surface 110 in sequence; the holding assembly 200 includes a holding member 210, and the holding member 210 has a second surface 211. The second surface 211 is used to cooperate with the first surface 110. Herein, cooperation means that the second surface 211 acts on the battery wafer to press the battery wafer onto the first surface 110. In other words, under the drive of the holding member 210, the second surface 211 presses the battery wafer so that the battery wafer fits onto the first surface 110; thus, under the cooperation of the first surface 110 and the second surface 211, the battery wafer is clamped between the carrier 100 and the holding member 210, thereby realizing the fixation of the battery wafer, preventing the battery wafer from falling, and at the same time ensuring the contact between the battery wafer and the solder tape.

[0042] It should be noted that the holding component 200 in this embodiment is used to fix the battery cells. Therefore, it is applicable to the following laying sequence of the welding tape and the battery cells. The laying sequence of the welding tape and the battery cells is as follows: first, lay the welding tape on the first surface 110, and then lay the battery cells on the welding tape, that is, lay the battery cells on the first surface 110 where the welding tape has been laid. Therefore, it can also be regarded as laying the battery cells on the first surface 110. If the battery cells are laid on the first surface 110 first and then the welding tape is laid on the battery cells, in this way, the welding tape itself can bundle and fix the battery cells, and the holding component 200 can be omitted. Of course, in order to improve the contact between the battery cells and the welding tape, the holding component 200 can also be further provided on the welding tape. Among them, the welding tape can be wound around the carrier 100 in a winding form, so as to form a dense welding tape network on the first surface 110, and the battery cells are laid on the welding tape network so that the battery cells are in contact with the welding tape for subsequent welding processing of the battery cells and the welding tape. It can be understood that after welding, the welding tape and the battery cells need to be cured. Generally, the curing method is ultraviolet lamp curing. Therefore, the holding member 210 can be made of a transparent material or the holding member 210 is provided with a hollow (for example, the holding member 210 is in a mesh shape), so that ultraviolet light can penetrate the holding member 210 to the battery cells.

[0043] Further, as Figure 1 , 2 shown, the holding member 210 acts on the carrier 100 under external drive. Therefore, the holding member 210 is controlled to form at least a first state and a second state: in the first state, the holding member 210 acts on the carrier 100 to press the second surface 211 against the battery cells on the first surface 110; in the second state, the holding member 210 is separated from the carrier 100, that is, there is no pressing or being pressed relationship between the second surface 211 and the first surface 110.

[0044] Among them, the first surface 110 of the carrier 100 and the second surface 211 of the holding member 210 cooperate with each other to fix the battery cells. The shapes of the first surface 110 and the second surface 211 need to match so that the battery cells can have a good contact effect with the welding tape when being pressed on the first surface 110; in one embodiment, the first surface 110 and the second surface 211 can be set as flat surfaces, so that the battery cells are pressed on the first surface 110 in a straight state; in another embodiment, the first surface 110 and the second surface 211 can be set as arc surfaces, so that the battery cells are pressed on the first surface 110 in an arc state.

[0045] It should be noted that, as Figure 2 shown, the first surface 110 and / or the second surface 211 can be formed by an entity, that is, the carrier 100 has an entity with the first surface 110 and / or the holding member 210 has an entity with the second surface 211; or, as Figure 3As shown, the first surface 110 and / or the second surface 211 can be formed by a virtual body, that is, the carrier 100 has a plurality of first components 111 to form a virtual first surface 110 and / or the holder 210 has a plurality of second components 212 to form a virtual second surface 211. Similarly, the battery cell can be pressed onto the second surface 211 through the first surface 110.

[0046] Specifically, as Figures 4 - 6 shown, the carrier 100 is set in a drum shape and has a rotational degree of freedom of rotating around an axis. Driven by an external force, the carrier 100 can rotate around the axis; a plurality of first surfaces 110 are provided on the circumferential side of the carrier 100, and the first surfaces 110 are annularly distributed on the circumferential side of the carrier 100 around the rotation axis of the carrier 100; the welding tape is wound around the carrier 100 in a winding form, passes through each first surface 110, and then the battery cell is disposed on the first surface 110 (welding tape). The battery cell is pressed by the holder 210 so that the battery cell is pressed onto the first surface 110 (welding tape). When the first surface 110 is set as a plane, the shape of the carrier 100 can be a straight triangular prism, a straight quadrangular prism, a straight pentagonal prism, a straight hexagonal prism... and a straight n-prism. Of course, in order to make the length of the welding tape on the first surface 110 meet the requirements of the battery cell, the size and shape of the first surface 110 are reasonably selected. Preferably, the carrier 100 can be a straight hexagonal prism, a straight octagonal prism, a straight decagonal prism or a straight dodecagonal prism; when the first surface 110 is set as a curved surface, the carrier 100 can be set as a prism with a curved side surface; when the number of side surfaces is large, it approaches a cylinder. For example, a dodecagonal prism with a curved side surface, or the carrier 100 is directly set as a cylinder.

[0047] As Figures 4 - 6 shown, when the carrier 100 is set in a drum shape and a plurality of first surfaces 110 are provided on the circumferential side of the carrier 100, the carrier 100 is driven to rotate so that the battery cell is disposed on each first surface 110. When the battery cell is disposed, the battery cell needs to be fixed by the holder 210 so that the battery cell on each first surface 110 can be pressed onto the first surface 110 (welding tape). Therefore, in order to ensure the fixing effect of the holder 210 pressing the battery cell onto the carrier 100 and prevent the holder 210 from falling off when the carrier 100 rotates, a connection is needed between the holder 210 and the carrier 100. More specifically, the shape of the carrier 100 is not limited to the drum shape, and can also be set in a semi-circular arc shape, a plate shape (not shown), etc. The shapes of the first surface 110 and the second surface 211 can be selected as a plane or a curved surface based on actual processing needs.

[0048] When the number of the first surfaces 110 on the carrier 100 is set to be multiple, in one embodiment, the number of the holding members 210 is the same as that of the first surfaces 110, that is, the number of the second surfaces 211 is the same as that of the first surfaces 110, so that each second surface 211 on the holding member 210 can cooperate with each first surface 110 on the carrier 100 in a one-to-one correspondence; in other embodiments, as Figure 7 shown, the second surfaces 211 on the same holding member 210 cooperate with multiple first surfaces 110. For example, the area of the second surface 211 is relatively large, and it can cooperate with two or more first surfaces 110 on the carrier 100 at the same time.

[0049] As Figure 8 , 9 shown, the holding assembly 200 and the carrier 100 are detachably connected, so that the holding assembly 200 can be temporarily fixedly connected to the carrier 100 to press the battery cell on the first surface 110. At the same time, the holding assembly 200 can move together with the carrier 100. After the welding tape and the battery cell are welded, the holding assembly 200 can be detached and separated from the carrier 100. A mating connection is formed between the holding assembly 200 and the carrier 100. Among them, the mating connection means that through magnetic connection or having a tendency of magnetic connection, through adsorption connection or having a tendency of adsorption connection, or bonding, the first surface 110 can cooperate with the second surface 211. Further, a mating connection is formed between the holding assembly 200 and the carrier 100.

[0050] In the first embodiment, the holding assembly 200 and the carrier 100 can be magnetically connected. When one of the holding assembly 200 and the carrier 100 has magnetism and the other has ferromagnetism, or both the holding assembly 200 and the carrier 100 have magnetism, the holding assembly 200 and the carrier 100 can be magnetically connected to realize the cooperation between the first surface 110 and the second surface 211; it can be understood that under the action of the magnetic field, there is an interaction force without contact. Therefore, without contact between the holding assembly 200 and the carrier 100, the cooperation between the first surface 110 and the second surface 211 can also be realized through the magnetic force, that is, there is a tendency of magnetic connection between the holding assembly 200 and the carrier 100.

[0051] In the second embodiment, the holding component 200 and the carrier 100 can be connected by vacuum adsorption. When one of the holding component 200 and the carrier 100 has the ability of vacuum adsorption, or both the holding component 200 and the carrier 100 have the ability of vacuum adsorption, the holding component 200 and the carrier 100 can be connected by vacuum adsorption to realize the cooperation between the first surface 110 and the second surface 211; the ability of vacuum adsorption means evacuating the air to make it have the adsorption ability, which can be realized by setting a vacuum adsorption structure on the holding component 200 or the carrier 100, and will not be elaborated here; it can be understood that under the action of vacuum adsorption, there is also an interaction force without contact. Therefore, when the holding component 200 and the carrier 100 are not in contact, the cooperation between the first surface 110 and the second surface 211 can also be realized through the adsorption action, that is, there is a tendency of vacuum adsorption connection between the holding component 200 and the carrier 100.

[0052] In the third embodiment, the holding component 200 and the carrier 100 can be bonded. When one of the holding component 200 and the carrier 100 has adhesiveness, or both the holding component 200 and the carrier 100 have adhesiveness, the holding component 200 and the carrier 100 can be bonded to realize the cooperation between the first surface 110 and the second surface 211.

[0053] Specifically, as Figure 8 shown, the carrier 100 and the holding component 200 are connected or have a tendency to be connected by the first connecting member 1121 and the second connecting member 2131, so that the first surface 110 can cooperate with the second surface 211. In one embodiment, the first connecting member 1121 is arranged on the first surface 110, and the second connecting member 2131 is arranged on the second surface 211. The first connecting member 1121 is used to connect and cooperate with the second connecting member 2131. Among them, the cooperation connection is formed between the first connecting member 1121 and the second connecting member 2131; in another embodiment, as Figure 9As shown, a first connecting portion 112 is provided on the carrier 100. The first connecting portion 112 is located outside the first surface 110. A first connecting member 1121 is provided on the first connecting portion 112. A second connecting portion 213 is provided on the holding member 210. The second connecting portion 213 is located outside the second surface 211. A second connecting member 2131 is provided on the second connecting portion 213. The first connecting member 1121 is used for connecting and cooperating with the second connecting member 2131. Among them, a mating connection is formed between the first connecting member 1121 and the second connecting member 2131. It should be noted that when the first connecting member 1121 has magnetism, the second connecting member 2131 can be omitted or the second connecting member 2131 is a part of the holding member 210 (or the second connecting portion 213), that is, the first connecting member 1121 is directly associated with the holding member 210 through the magnetism of the first connecting member 1121. When the second connecting member 2131 has magnetism, the first connecting member 1121 can be omitted or the first connecting member 1121 is a part of the carrier 100 (or the first connecting portion 112), that is, the second connecting member 2131 is directly associated with the carrier 100 through the magnetism of the second connecting member 2131. It can be understood that when the first connecting member 1121 is provided on the first surface 110 and the second connecting member 2131 is provided on the second surface 211, the positions of the first connecting member 1121 and the second connecting member 2131 should avoid the solar cell.

[0054] Further, as Figure 10 shown, a positioning structure is provided between the carrier 100 and the holding assembly 200. The positioning structure is used for the plug-in positioning cooperation between the holding assembly 200 and the carrier 100, so that the first connecting member 1121 and the second connecting member 2131 can be quickly matched, and also so that the first surface 110 and the second surface 211 can be correspondingly matched. Specifically, a positioning pin 113 is provided on the first surface 110, and a positioning groove 214 is provided on the second surface 211; or a positioning groove 214 is provided on the first surface 110, and a positioning pin 113 is provided on the second surface 211; the positioning pin 113 and the positioning groove 214 are in plug-in cooperation, and the number of the positioning pin 113 and the positioning groove 214 can be set to be multiple, and the positioning pin 113 and the positioning groove 214 are in one-to-one correspondence and cooperation.

[0055] As Figure 11 shown, the processing device provided in this application further includes an adjusting member 220. The adjusting member 220 acts on the holding member 210 to make the acting force of the holding member 210 on the carrier 100 adjustable. In other words, the second surface 211 of the holding member 210 presses on the first surface 110 of the carrier 100, and the solar cell is located between the first surface 110 and the second surface 211. Adjusting the acting force of the holding member 210 on the carrier 100 is to adjust the magnitude of the pressure on the solar cell.

[0056] In one embodiment, as Figure 12As shown, the carrier 100 and the holder 210 are connected by a first connecting member 1121 located on the carrier 100 and a second connecting member 2131 located on the holder 210 in the form of magnetic attraction, vacuum adsorption or bonding: the adjusting member 220 acts on the holder 210, and the acting force F of the holder 210 on the battery cell is F = F'+ G ± f, where F' refers to the acting force formed by the cooperation connection between the holder 210 and the carrier 100, for example: magnetic attraction, adsorption (if it is bonding, then F' = 0); G is the gravity of the holder 210; f is an adjustment term, that is, the acting force of the elastic member 223 on the holder 210. The adjusting member 220 includes a support rod 221, an adjusting portion 222 and an elastic member 223. The support rod 221 is movably connected to the holder 210. The support rod 221 is used to abut and cooperate with the carrier 100 or to be connected to the carrier 100; the adjusting portion 222 is synchronously movably connected to the support rod 221 and the holder 210; the elastic member 223 is arranged on the adjusting portion 222 and acts on the support rod 221 or the carrier 100, so that the elastic member 223 forms an elastic force on the holder 210 along the second direction. The second direction refers to the direction from the carrier 100 to the holder 210, and the second direction can also be a negative direction; thus, by adjusting the position of the adjusting portion 222 on the support rod 221 to adjust the elastic force formed by the elastic member 223, the acting force of the holder 210 on the carrier 100 is adjusted. Among them, the support rod 221 can also form a mating connection with the carrier 100.

[0057] Specifically, as Figure 12 shown, the support rod 221 passes through the holder 210, so that the holder 210 is movable relative to the support rod 221. When the first surface 110 and the second surface 211 are mated, the support rod 221 abuts against the carrier 100; a limiting portion 224 is arranged on the support rod 221, and the limiting portion 224 and the adjusting portion 222 are located on different sides of the holder 210; or the limiting portion 224 is arranged on the carrier 100; the adjusting portion 222 is threadedly connected to the support rod 221 and the holder 210 (or the sleeve 225 arranged on the holder 210) respectively, so that the adjusting portion 222 can move synchronously relative to the holder 210 and the support rod 221 to adjust the position of the adjusting portion 222; the elastic member 223 is a spring, and the spring is sleeved on the support rod 221, and the spring is respectively connected to or abuts against the adjusting portion 222 and the limiting portion 224. By adjusting the position of the adjusting portion 222, the change amount of the spring is adjusted, so that the acting force of the spring on the adjusting portion 222 changes, that is, the upward elastic force or the downward pulling force on the holder 210 changes; the spring can be in a compressed or stretched state. When the spring is in the stretched state: the acting force F of the holder 210 on the battery cell is F = F'+ G + f; when the spring is in the compressed state: the acting force F of the holder 210 on the battery cell is F = F'+ G - f.

[0058] In another embodiment, as Figure 13As shown, the carrier 100 and the holder 210 are connected by a first connecting member 1121 located on the carrier 100 and a second connecting member 2131 located on the holder 210 in the form of magnetic attraction, vacuum adsorption or bonding: The adjusting member 220 acts on the holder 210, and the acting force F of the holder 210 on the battery cell is F = F' + G ± f, where F' refers to the acting force realized by the mating connection between the holder 210 and the carrier 100, for example: magnetic attraction, adsorption (if it is bonding, then F' = 0); G is the gravity of the holder 210; f is the adjustment term, that is, the acting force of the elastic member 223 on the holder 210. The adjusting member 220 includes a support rod 221, an adjusting portion 222 and an elastic member 223. The support rod 221 is movably connected to the holder 210. The support rod 221 is used to abut and cooperate with the carrier 100 or to be connected to the carrier 100; the adjusting portion 222 is movably connected to the support rod 221; the elastic member 223 is arranged on the adjusting portion 222 and acts on the holder 210 to form an elastic force on the holder 210 along a first direction. The first direction refers to the direction from the holder 210 to the carrier 100, and the first direction can also be the negative direction; thus, by adjusting the position of the adjusting portion 222 on the support rod 221, the elastic force formed by the elastic member 223 is adjusted, so as to adjust the acting force of the holder 210. Wherein, the support rod 221 can also form a mating connection with the carrier 100.

[0059] Specifically, as Figure 13 shown, the support member passes through the holder 210, so that the holder 210 is movable relative to the support rod 221. When the first surface 110 and the second surface 211 are mated, the support rod 221 abuts on the carrier 100; the adjusting portion 222 is threadedly connected to the support rod 221; the elastic member 223 is a spring. The spring is sleeved on the support rod 221, and both ends of the spring are respectively connected to or abut on the adjusting portion 222 and the holder 210. By adjusting the position of the adjusting portion 222, the change amount of the spring is adjusted, so that the acting force of the spring on the adjusting portion 222 changes, that is, the upward elastic force or the downward pulling force on the holder 210 changes; the spring can be in a compressed or stretched state. When the spring is in the stretched state: the acting force F of the holder 210 on the battery cell is F = F' + G + f; when the spring is in the compressed state: the acting force F of the holder 210 on the battery cell is F = F' + G - f.

[0060] In other embodiments, as Figure 14As shown, a mating connection is formed between the adjusting member 220 and the carrier 100, and the carrier 100 and the holding member 210 are connected through the adjusting member 220: The adjusting member 220 acts on the holding member 210, and the force F exerted by the holding member 210 on the battery cell is F = G + f, where G is the gravity of the holding member 210; f is an adjustment term, that is, the force exerted by the elastic member 223 on the holding member 210. The adjusting member 220 includes a support rod 221, an adjusting portion 222, and an elastic member 223. The support rod 221 is movably connected to the holding member 210, and the support rod 221 is connected to the carrier 100; the adjusting portion 222 is movably connected to the support rod 221; the elastic member 223 is disposed on the adjusting portion 222 and acts on the holding member 210 to form an elastic force on the holding member 210 in a first direction. The first direction refers to the direction from the holding member 210 to the carrier 100, and the first direction can also be a negative direction; thus, by adjusting the position of the adjusting portion 222 on the support rod 221, the elastic force formed by the elastic member 223 is adjusted, thereby adjusting the action of the holding member 210.

[0061] Specifically, as Figure 14 shown, the support member passes through the holding member 210, so that the holding member 210 is movable relative to the support rod 221. When the first surface 110 and the second surface 211 are engaged, the support rod 221 is connected to the carrier 100; the adjusting portion 222 is threadedly connected to the support rod 221; the elastic member 223 is a spring, and the spring is sleeved on the support rod 221. The two ends of the spring are respectively connected to or abutted against the adjusting portion 222 and the holding member 210. The spring is in a compressed state. By adjusting the position of the adjusting portion 222, the compression amount of the spring is adjusted, so that the force exerted by the spring on the adjusting portion 222 changes, that is, the downward pulling force on the holding member 210 changes; when the spring is in the compressed state: the force F exerted by the holding member 210 on the battery cell is F = G + f.

[0062] As Figure 15As shown, the processing device provided by the present application also includes a grabbing assembly 230, which is used to grab the battery cell and the holding assembly 200. The grabbing assembly 230 includes a first grabbing member 231 and a second grabbing member 232.

In one embodiment, the first gripping member 231 and the second gripping member 232 can grab the holding member 210 and the battery cell in the form of vacuum adsorption.

[0063] Further, such as Figure 16 As shown, the retaining component 200 has a clearance space 215, and one or more clearance spaces 215 can be provided so that the second grasping member 232 can pass through the retaining component 200 through the clearance space 215; in one embodiment, the clearance space 215 refers to a channel opened in the retaining member 210 to allow the second grasping member 232 to extend through the channel. Before the retaining member 210 and the battery cells are loaded, the battery cells of the retaining member 210 are first stacked, and the grasping component 230 can grasp the retaining member 210 and the battery cells simultaneously.

[0064] Working principle / steps:

[0065] The processing device works in coordination with the carrier 100 and the holding assembly 200. The carrier 100 serves as the basis for the layout of the solder strip and the battery cell. The holding assembly 200 applies pressure to the battery cell through the second surface 211, so that the battery cell is stably fixed on the first surface 110 of the carrier 100, ensuring close contact with the solder strip. The holding assembly 200 is detachably connected to the carrier 100. The holding assembly 200 can be controlled to fix the battery cell in the first state and to be separated from the carrier 100 in the second state, which is convenient for the processing process and subsequent disassembly.
