[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, thereby achieving the technical effect of improving the simplified structure of the carrier 100.

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

[0040] The present application embodiment provides a processing device for processing battery cells and welding strips, such as Figure 1 As shown, it includes a carrier 100 and a retaining assembly 200 . The carrier 100 is used as a basis for laying out the battery cells and / or welding strips. The retaining assembly 200 is used to press the battery cells onto the carrier 100 so that the battery cells are stably fixed on the carrier 100 .

[0041] Specifically, Figure 1 , 2 As shown, the carrier 100 has a first surface 110, and the welding strip and the battery cell are arranged on the first surface 110 in sequence; the retaining component 200 includes a retaining member 210, and the retaining member 210 has a second surface 211, and the second surface 211 is used to cooperate with the first surface 110, wherein cooperation refers to the second surface 211 acting on the battery cell so that the battery cell is pressed on the first surface 110, in other words, when the retaining member 210 is driven, the second surface 211 applies pressure to the battery cell so that the battery cell is attached to the first surface 110; in this way, under the cooperation of the first surface 110 and the second surface 211, the battery cell is clamped between the carrier 100 and the retaining member 210, so as to fix the battery cell and prevent the battery cell from falling, while ensuring the contact between the battery cell and the welding strip.

[0042] It is worth noting that the retaining assembly 200 in this embodiment is used to fix the battery cell, and therefore, it is applicable to the following arrangement sequence of the welding tape and the battery cell, and the arrangement sequence of the welding tape and the battery cell is: firstly arrange the welding tape on the first surface 110, and then arrange the battery cell on the welding tape, that is, arrange the battery cell on the first surface 110 after the welding tape is arranged, so it can also be regarded as arranging the battery cell on the first surface 110. If the battery cell is firstly arranged on the first surface 110, and then the welding tape is arranged on the battery cell, in this way, the welding tape itself can bind and fix the battery cell, and the retaining assembly 200 can be omitted. Of course, in order to improve the contact between the battery cell and the welding tape, the retaining assembly 200 can also be further arranged on the welding tape. Among them, the welding tape can be wound on the carrier 100 in the form of a roll, so that a dense welding tape net is formed on the first surface 110, and the battery cell is arranged on the welding tape net so that the battery cell contacts the welding tape, so as to facilitate the subsequent welding process of the battery cell and the welding tape. It is understandable that after welding, the solder strip and the battery cell need to be cured. Generally, the curing method is ultraviolet lamp curing. Therefore, the retaining member 210 can be made of a transparent material or the retaining member 210 can be hollowed out (for example, the retaining member 210 is mesh-shaped) to allow ultraviolet light to penetrate the retaining member 210 to the battery cell.

[0043] Further, such as Figure 1 , 2 As shown, the retaining member 210 is driven externally to act on the carrier 100, so the retaining member 210 is controlled to form at least a first state and a second state: in the first state, the retaining member 210 acts on the carrier 100, so that the second surface 211 presses the battery cell on the first surface 110; in the second state, the retaining member 210 is separated from the carrier 100, that is, there is no pressure-applying or pressure-receiving 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 retaining member 210 cooperate with each other to fix the battery cell, and the shapes of the first surface 110 and the second surface 211 need to match so that the battery cell can have a good contact effect with the welding strip when it is pressed on the first surface 110; in one embodiment, the first surface 110 and the second surface 211 can be set to planes, so that the battery cell is pressed on the first surface 110 in a flat state; in another embodiment, the first surface 110 and the second surface 211 can be set to arc surfaces, so that the battery cell is pressed on the first surface 110 in an arc state.

[0045] It is worth noting that if Figure 2 As shown, the first surface 110 and / or the second surface 211 may be formed by a solid body, that is, the carrier 100 has a solid first surface 110 and / or the holder 210 has a solid second surface 211; or 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 retaining member 210 has a plurality of second components 212 to form a virtual second surface 211, and the battery cell can also be pressed on the second surface 211 through the first surface 110.

[0046] Specifically, Figure 4-6 As shown, the carrier 100 is configured to be roller-shaped, and the carrier 100 has a rotational freedom of rotating around an axis. When driven by an external force, the carrier 100 can rotate around the axis. A plurality of first surfaces 110 are provided on the peripheral side surface of the carrier 100, and the first surfaces 110 are distributed on the peripheral side of the carrier 100 in a ring shape around the rotation axis of the carrier 100. The welding strip is wound on the carrier 100 in the form of a roll, and the welding strip passes through each first surface 110, and then the battery cell is arranged on the first surface 110 (welding strip), and the battery cell is pressed by the retaining member 210 so that the battery cell is pressed on the first surface 110 (welding strip). When the first surface 110 is set as a plane, the shape of the carrier 100 can be a right triangular prism, a right quadrangular prism, a right pentagonal prism, a right hexagonal prism... and a right n-prism. Of course, in order to ensure that the length of the welding strip on the first surface 110 meets 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 right hexagonal prism, a right octagonal prism, a right decagonal prism or a right dodecagonal prism; when the first surface 110 is set as an arc surface, the carrier 100 can be set as a prism with arc-surface sides; when the number of sides is large, it approaches a cylinder, for example: a dodecagonal prism with arc-surface sides, or the carrier 100 is directly set as a cylinder.

[0047] like Figure 4-6 As shown, when the carrier 100 is set to a roller shape, and a plurality of first surfaces 110 are set on the circumference of the carrier 100, the carrier 100 is driven to rotate so that the battery cells are arranged on each first surface 110. While the battery cells are arranged, the battery cells need to be fixed by the retaining member 210 so that the battery cells on each first surface 110 can be pressed on the first surface 110 (welding strip). Therefore, in order to ensure the fixing effect of the retaining member 210 pressing the battery cells on the carrier 100 and prevent the retaining member 210 from falling when the carrier 100 rotates, the retaining member 210 and the carrier 100 need to be connected. More specifically, the shape of the carrier 100 is not limited to the roller shape, and can also be set to a semicircular arc shape, a plate shape (not shown) and other shapes. The shapes of the first surface 110 and the second surface 211 can be selected as a plane or an arc surface based on actual processing needs.

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

[0049] like Figure 8 , 9 As shown, the holding component 200 and the carrier 100 are detachably connected, so that the holding component 200 can be temporarily fixedly connected to the carrier 100 to press the battery cell on the first surface 110, and the holding component 200 can move with the carrier 100. After the welding ribbon and the battery cell are welded, the holding component 200 can be detached and separated from the carrier 100. A mating connection is formed between the holding component 200 and the carrier 100, wherein the mating connection refers to a magnetic connection or a tendency of magnetic connection, an adsorption connection or a tendency of adsorption connection, or bonding, so that the first surface 110 can be mated with the second surface 211. Further, a mating connection is formed between the holding component 200 and the carrier 100.

[0050] In the first embodiment, the holding component 200 and the carrier 100 can be connected by magnetism. When one of the holding component 200 and the carrier 100 is magnetic and the other is ferromagnetic, or both of the holding component 200 and the carrier 100 are magnetic, the holding component 200 and the carrier 100 can be connected by magnetism to achieve the matching of 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 even without contact, so when the holding component 200 and the carrier 100 are not in contact, the first surface 110 and the second surface 211 can also be matched by the action of magnetic force, that is, there is a tendency for the holding component 200 and the carrier 100 to have a magnetic connection.

[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 vacuum adsorption capability, or both the holding component 200 and the carrier 100 have vacuum adsorption capability, the holding component 200 and the carrier 100 can be connected by vacuum adsorption to achieve the matching of the first surface 110 and the second surface 211; vacuum adsorption capability refers to vacuuming to have adsorption capability, and a vacuum adsorption structure can be set on the holding component 200 or the carrier 100 to achieve this, which will not be repeated here; it can be understood that under the action of vacuum adsorption, there is interaction force even without contact, so when the holding component 200 and the carrier 100 are not in contact, the first surface 110 and the second surface 211 can also be matched through adsorption, that is, there is a tendency for the holding component 200 and the carrier 100 to be connected by vacuum adsorption.

[0052] In the third embodiment, the holding component 200 and the carrier 100 can be bonded together. When one of the holding component 200 and the carrier 100 is adhesive, or both of the holding component 200 and the carrier 100 are adhesive, the holding component 200 and the carrier 100 can be bonded together to achieve the matching of the first surface 110 and the second surface 211.

[0053] Specifically, Figure 8 As shown, the carrier 100 and the holding assembly 200 are connected or have a tendency to be connected through the first connecting member 1121 and the second connecting member 2131, so that the first surface 110 can be matched with the second surface 211. In one embodiment, the first surface 110 is provided with a first connecting member 1121, and the second surface 211 is provided with a second connecting member 2131, and the first connecting member 1121 is used to connect and match with the second connecting member 2131, wherein the first connecting member 1121 and the second connecting member 2131 form the matching connection; in another embodiment, as Fig. 9As shown, the carrier 100 is provided with a first connecting portion 112, the first connecting portion 112 is located outside the first surface 110, and a first connecting member 1121 is provided on the first connecting portion 112. The retaining member 210 is provided with a second connecting portion 213, the second connecting portion 213 is located outside the second surface 211, and a second connecting member 2131 is provided on the second connecting portion 213. The first connecting member 1121 is used to connect and cooperate with the second connecting member 2131, wherein a matching connection is formed between the first connecting member 1121 and the second connecting member 2131; it is worth noting that in the first connecting member When the first connector 1121 is magnetic, the second connector 2131 can be omitted or the second connector 2131 is a part of the holder 210 (or the second connector 213), that is, the first connector 1121 is directly associated with the holder 210 through the magnetism of the first connector 1121; when the second connector 2131 is magnetic, the first connector 1121 can be omitted or the first connector 1121 is a part of the carrier 100 (or the first connector 112), that is, the second connector 2131 is directly associated with the carrier 100 through the magnetism of the second connector 2131. It can be understood that when the first connector 1121 is arranged on the first surface 110 and the second connector 2131 is arranged on the second surface 211, the positions of the first connector 1121 and the second connector 2131 should avoid the battery sheet.

[0054] Further, such as Fig.10 As shown, a positioning structure is provided between the carrier 100 and the retaining assembly 200, and the positioning structure is used for plug-in positioning cooperation between the retaining assembly 200 and the carrier 100, so that the first connecting member 1121 and the second connecting member 2131 can be quickly matched, and 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 plug-in matched, and the number of the positioning pin 113 and the positioning groove 214 can be set to multiple, and the positioning pin 113 and the positioning groove 214 are matched one by one.

[0055] like Fig.11 As shown, the processing device provided in the present application also includes an adjusting member 220, which acts on the retaining member 210 to make the force of the retaining member 210 acting on the carrier 100 adjustable. In other words, the second surface 211 of the retaining member 210 applies pressure to the first surface 110 of the carrier 100, and the battery cell is located between the first surface 110 and the second surface 211. Adjusting the force of the retaining member 210 on the carrier 100 adjusts the size of the pressure on the battery cell.

[0056] In one embodiment, Fig.12As shown, the carrier 100 and the retaining member 210 are connected by a first connecting member 1121 located on the carrier 100 and a second connecting member 2131 located on the retaining member 210 in the form of magnetic attraction, vacuum adsorption or bonding: the adjusting member 220 acts on the retaining member 210, and the force F=F'+G±f exerted by the retaining member 210 on the battery cell, wherein F' refers to the force formed by the matching connection between the retaining member 210 and the carrier 100, for example: magnetic attraction, adsorption (if it is bonding, F'=0); G is the gravity of the retaining member 210; f is the adjustment item, that is, the force exerted by the elastic member 223 on the retaining 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 used to contact with the carrier 100 or to connect with the carrier 100. The adjusting portion 222 is synchronously movably connected to the support rod 221 and the holding member 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 along the second direction on the holding member 210, and the second direction refers to the direction of the carrier 100 toward the holding member 210, and the second direction can also be a negative direction. In this way, the elastic force formed by the elastic member 223 is adjusted by adjusting the position of the adjusting portion 222 on the support rod 221, thereby adjusting the force of the holding member 210 acting on the carrier 100. Among them, the support rod 221 can also form a matching connection with the carrier 100.

[0057] Specifically, Fig.12 As shown, the support rod 221 is passed through the retaining member 210, so that the retaining member 210 can move relative to the support rod 221, and when the first surface 110 and the second surface 211 are matched, the support rod 221 abuts against the carrier 100; a limiting portion 224 is provided on the support rod 221, and the limiting portion 224 and the adjusting portion 222 are located on the opposite side of the retaining member 210; or the limiting portion 224 is provided on the carrier 100; the adjusting portion 222 is threadedly connected to the support rod 221 and the retaining member 210 (or a sleeve 225 provided on the retaining member 210), respectively, so that the adjusting portion 222 can move synchronously relative to the retaining member 210 and the support rod 221 to adjust the position of the adjusting portion 222; the elastic member 223 is a spring, 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 force exerted by the spring on the adjusting portion 222 changes, that is, the upward elastic force or downward pulling force on the retaining member 210 changes; the spring can be in a compressed or stretched state. When the spring is in a stretched state: the force exerted by the retaining member 210 on the battery cell is F=F'+G+f; when the spring is in a compressed state: the force exerted by the retaining member 210 on the battery cell is F=F'+G-f.

[0058] In another embodiment, Fig.13As shown, the carrier 100 and the retaining member 210 are connected by a first connecting member 1121 located on the carrier 100 and a second connecting member 2131 located on the retaining member 210 in the form of magnetic attraction, vacuum adsorption or bonding: the adjusting member 220 acts on the retaining member 210, and the force F=F'+G±f exerted by the retaining member 210 on the battery cell, wherein F' refers to the force achieved by the matching connection between the retaining member 210 and the carrier 100, for example: magnetic attraction, adsorption (if it is bonding, F'=0); G is the gravity of the retaining member 210; f is the adjustment item, that is, the force exerted by the elastic member 223 on the retaining member 210. The adjusting member 220 includes a support rod 221, an adjusting portion 222, and an elastic member 223.

[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.
