Description

Technical Field

[0001] This application relates to the field of battery assembly equipment technology, and in particular to a battery assembly fixture and battery assembly system. Background Technology

[0002] The production of steel button batteries is challenging due to their small size and high precision requirements. To improve processing and assembly accuracy, suitable fixtures are typically used to secure the batteries.

[0003] However, in the current production process of steel button batteries, multiple processes are usually required, such as applying adhesive to the top of the battery, placing the positive electrode nickel sheet, welding the positive electrode nickel sheet, welding the negative electrode nickel sheet, and 114. Because each process operates on a different part of the battery (for example, the positive electrode nickel sheet welding process requires welding on the positive electrode side of the battery, while the negative electrode nickel sheet welding process usually requires welding on the side of the battery), different fixtures are often required for different processes. This means that after each process is completed, the battery needs to be re-clamped and replaced with a different fixture, which not only greatly affects the assembly efficiency of the battery, but also increases the manufacturing cost of the fixture. Utility Model Content

[0004] The purpose of this application is to provide a battery assembly fixture and a battery assembly system, which can solve to some extent the technical problem in the prior art that, due to the different positions of each process acting on the battery, different fixtures are often required for different processes. This means that after each process is completed, the battery needs to be replaced with a new fixture and re-clamped, which not only greatly affects the battery assembly efficiency but also increases the manufacturing cost of the fixture.

[0005] According to a first aspect of this application, a battery assembly fixture is provided, including a battery placement assembly. The battery placement assembly includes a clamping body, the clamping body includes a battery fixing member, the battery fixing member includes a battery clamping groove, a clamping member, and a driving member. The clamping member is disposed on one side of the battery clamping groove in a first direction, and at least a portion of the clamping member can extend into the battery clamping groove. The driving member is convexly connected to the clamping member to drive the clamping member to clamp and release the battery to be processed in the battery clamping groove.

[0006] The battery clamp has a first opening on one side in the second direction, so that the battery to be processed can be inserted into the battery clamp and the positive electrode side of the battery to be processed inserted into the battery clamp is exposed by the first opening. The second direction intersects with the first direction.

[0007] The battery clamping slot has an operating port on the abutting side wall at the end away from the clamping member in the first direction, which communicates with the battery clamping slot. When the battery to be processed is clamped between the abutting side wall and the clamping member, the negative electrode welding position of the battery to be processed is exposed by the operating port.

[0008] Preferably, the clamping body further includes at least two first adhesive tape positioning portions, which protrude from the side of the clamping body where the first opening is located, to position the insulating adhesive tape material for attaching to the positive electrode side of the battery to be processed.

[0009] Preferably, the clamping body includes:

[0010] The battery clamping part is provided with the battery fixing member and the battery clamping groove extends through the clamping part in the second direction, so that a second opening is formed on the other side of the battery clamping groove in the second direction;

[0011] The support portion is detachably connected to the clamping portion, and the support portion is disposed on the side of the clamping portion opposite to the first opening.

[0012] At least two second adhesive tape positioning portions protrude from the side of the clamping body where the second opening is located, in order to position the insulating adhesive tape material for attaching to the back of the battery to be processed on the side facing away from the positive electrode.

[0013] Preferably, the battery mounting assembly further includes a positive electrode nickel sheet positioning part, which is detachably connected to the side of the first open opening of the clamping body;

[0014] The positive electrode nickel sheet positioning part is provided with a positive electrode nickel sheet positioning hole that penetrates the positive electrode nickel sheet positioning part along the second direction. When the positive electrode nickel sheet positioning part is set in the clamping body, the positive electrode nickel sheet positioning hole is correspondingly set with the first open opening so that the positive electrode nickel sheet is set in the designated position of the battery to be processed through the positive electrode nickel sheet positioning hole.

[0015] Preferably, the battery mounting assembly further includes a welding block, which is detachably connected to the side of the positive electrode nickel sheet positioning portion opposite to the clamping body;

[0016] The welding block is provided with a pressing protrusion, which protrudes along the second direction toward the side where the positive nickel sheet positioning part is located. When the welding block is set in the positive nickel sheet positioning part, the pressing protrusion can extend into the positive nickel sheet positioning hole and abut against the positive nickel sheet.

[0017] The welding block is also provided with a first weld point positioning hole that penetrates the welding block along the second direction.

[0018] Preferably, the battery mounting assembly further includes a negative electrode solder joint positioning part, which is detachably connected to the side of the clamping body where the operating port is located;

[0019] The negative electrode solder joint positioning part is provided with a second solder joint positioning hole, which penetrates the negative electrode solder joint positioning part along the first direction. When the negative electrode solder joint positioning part is set in the clamping body, the second solder joint positioning hole is correspondingly set with the operation port.

[0020] Preferably, it further includes a first positioning base, which is located on the side of the battery mounting assembly opposite to the first opening in the second direction;

[0023] The second positioning base is provided with a second slot, and the battery mounting assembly is detachably engaged with the second slot.

[0024] Preferably, the clamping body includes a plurality of battery fixing members, which are spaced apart on the clamping body along a third direction, and the third direction intersects the plane defined by the first direction and the second direction.

[0025] According to a second aspect of this application, a battery assembly system is provided, including the battery assembly fixture described in any of the above technical solutions, and thus has all the beneficial technical effects of the battery assembly fixture, which will not be repeated here.

[0026] Compared with the prior art, the beneficial effects of this application are as follows:

[0027] The battery assembly fixture provided in this application, on the one hand, uses a drive component to control the clamping component to fix the battery. With the first open port exposing the positive electrode and the operating port exposing the negative electrode, multiple processes such as top surface adhesive application, positive electrode welding, and negative electrode welding can be completed in a single clamping operation. Compared to the traditional method of changing the fixture at least once for each process, this not only reduces the number of clamping operations and saves clamping time, but also significantly improves battery assembly efficiency. Furthermore, one fixture can handle multiple processing steps, effectively reducing the number of fixtures and significantly reducing fixture manufacturing costs. On the other hand, the battery can be directly pushed in from the first open port on the side, and clamping can be achieved through the linkage of the clamping component and the drive component. This not only effectively simplifies the clamping operation, reduces clamping time, and improves the clamping success rate, but also eliminates the cumulative positioning errors caused by multiple clamping operations by replacing multiple clamping operations with a single clamping operation, further improving assembly accuracy and yield. Moreover, this allows the battery assembly fixture to support steel button batteries of different specifications, improving the versatility of the battery assembly fixture.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] The following reference Figures 1 to 9 This application describes a battery assembly fixture and battery assembly system according to some embodiments.

[0048] See Figures 1 to 9 As shown, an embodiment of the first aspect of this application provides a battery assembly fixture, which includes a battery placement assembly. The battery placement assembly includes a clamping body 1, which includes a battery fixing member. The battery fixing member includes a battery clamping slot, a clamping member 111, and a driving member 112. The clamping member 111 is disposed on one side of the battery clamping slot in a first direction F1, and at least a portion of the clamping member 111 can extend into the battery clamping slot. The driving member 112 is convexly connected to the clamping member 111 to drive the clamping member 111 to clamp and release the battery 5 (e.g., a button cell battery) to be processed in the battery clamping slot. A first opening 113 is formed on one side of the battery clamping slot in a second direction F2 to facilitate the insertion of the battery 5 to be processed into the battery clamping slot. The side of the battery 5 to be processed inserted into the battery clamping slot, where the positive electrode is located, is exposed by the first opening 113. The second direction F2 intersects the first direction F1. An operation port 115 communicating with the battery clamping slot is provided on the abutting side wall at the end away from the clamping member 111 in the first direction F1. When the battery to be processed 5 is clamped between the abutting side wall and the clamping member 111, the negative electrode welding position of the battery to be processed 5 is exposed by the operation port 115.

[0049] According to the battery assembly fixture provided by the above-mentioned technical features, on the one hand, the battery is fixed by the clamping component 111 controlled by the driving component 112. With the first open port 113 exposing the positive electrode and the operating port 115 exposing the negative electrode, multiple processes such as top surface adhesive application, positive electrode welding, and negative electrode welding can be completed in one clamping. Compared with the traditional mode of changing the fixture at least once for each process, this not only reduces the number of clamping times and saves clamping time, but also greatly improves the battery assembly efficiency. Moreover, one fixture can meet the processing of multiple processes, effectively reducing the number of fixtures and significantly reducing the manufacturing cost of fixtures. On the other hand, the battery can be directly pushed in from the first open port 113 on the side and clamped by the linkage of the clamping component 111 and the driving component 112. This not only simplifies the clamping operation, reduces the clamping time, and improves the clamping success rate, but also eliminates the superposition of positioning errors caused by multiple clampings by a single clamping, further improving the assembly accuracy and yield rate. In addition, the battery assembly fixture can support steel button batteries of different specifications, improving the versatility of the battery assembly fixture.

[0050] like Figures 1 to 9 As shown in the figure, F1 can be an example of the first direction F1 described above, and F2 can be an example of the second direction F2 described above, wherein the first direction F1 and the second direction F2 intersect. For ease of description, the direction intersecting the plane defined by the first direction F1 and the second direction F2 is defined as the third direction F3, and F3 shown in the figure can be an example of the third direction F3 described above. Preferably, any two of the first direction F1, the second direction F2, and the third direction F3 are perpendicular to each other, in order to accommodate the structure of most rectangular fixtures.

[0051] Preferably, such as Figure 5 As shown, the clamping body 1 may also be provided with a clamping and placement groove. The clamping and placement groove and the battery clamping groove are arranged side by side along the first direction F1, and one end of the clamping and placement groove in the first direction F1 is connected to the battery clamping groove. The clamping member 111 and the driving member 112 may be disposed in the clamping and placement groove, and the driving member 112 may be disposed between the clamping member 111 and the inner wall of the other end of the clamping and placement groove in the first direction F1, so as to drive the clamping member 111 to extend into / out of the battery clamping groove.

[0052] Preferably, such as Figure 5 As shown, the aforementioned driving member 112 can be a spring press-fitted between the clamping mounting groove and the clamping member 111 to simplify the structure of the driving member 112. However, it is not limited to this; the aforementioned driving member 112 can also be other linear drive structures, such as a cylinder, an electric cylinder, an electric telescopic rod, etc.

[0053] Preferably, such as Figure 5As shown, the clamping member 111 has a lever protrusion on the side opposite to the clamping body 1, so as to drive the clamping member 111 to compress the driving member 112 by driving the lever protrusion, so as to release the battery 5 to be processed that is inserted into the battery clamping slot.

[0054] Preferably, such as Figure 5 As shown, the size of the above-mentioned operating port 115 on the third direction F3 can be smaller than the diameter of the battery 5 to be processed, so as to ensure the clamping stability of the clamping body 1 on the abutting side wall of the battery 5 to be processed.

[0055] Preferably, such as Figure 1 and Figure 5 As shown, the clamping body 1 may further include at least two first adhesive tape positioning parts 116. The first adhesive tape positioning parts 116 protrude from the side where the first opening 113 of the clamping body 1 is located, so as to position the insulating adhesive tape material to be attached to the positive electrode side of the battery 5 to be processed. In this way, the insulating adhesive tape material is positioned by the first adhesive tape positioning parts 116, so that the clamping body 1 can meet the battery top surface adhesive application process.

[0056] like Figure 1 and Figure 5 As shown in the figure, an example of having two first adhesive tape positioning parts 116 is illustrated. The two first adhesive tape positioning parts 116 can be respectively disposed at both ends of the clamping body 1 in the third direction F3, so as to improve the accuracy and precision of positioning the insulating adhesive tape material.

[0057] Optionally, the first adhesive tape positioning part 116 mentioned above can be a positioning pin.

[0058] Preferably, such as Figures 1 to 5 As shown, the clamping body 1 may include a clamping part 11. The battery fixing members may all be disposed in the clamping part 11, and the battery clamping groove may penetrate the clamping part 11 along the second direction F2, so that a second opening 114 is formed on the other side of the battery clamping groove in the second direction F2. Thus, when the battery to be processed 5 is disposed in the battery clamping groove, the back side of the battery to be processed 5 may be exposed by the second opening 114, so that the bottom surface of the battery to be processed 5 may be assembled and processed through the second opening 114 (for example, performing a battery bottom surface adhesive process).

[0059] Similarly, such as Figure 3 As shown, the clamping body 1 may further include at least two second adhesive tape positioning portions 117. The second adhesive tape positioning portions 117 protrude from the side where the second opening 114 of the clamping body 1 is located, so as to position the insulating adhesive tape material used to attach to the side of the battery 5 facing away from the positive electrode. The structure and beneficial effects of the second adhesive tape positioning portion 117 are similar to those of the first adhesive tape positioning portion 116, and will not be described in detail here.

[0060] Preferably, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the clamping body 1 may further include a support portion 12, which can be detachably connected to the clamping portion 11. The support portion 12 is disposed on the side of the clamping portion 11 opposite to the first opening 113. Thus, on the one hand, when the support portion 12 is disposed on the side of the clamping portion 11 opposite to the first opening 113, it can effectively support the battery 5 to be processed in the battery clamping slot, so as to ensure the positioning accuracy of the battery 5 to be processed in the second direction F2 in the battery clamping slot, thereby ensuring the processing accuracy of the battery 5 to be processed; on the other hand, when the support portion 12 is removed from the clamping portion 11, the second opening 114 can be exposed, so as to facilitate the assembly and processing of the bottom surface of the battery 5 to be processed through the second opening 114.

[0061] Preferably, such as Figure 3 As shown, a first positioning structure (e.g., a positioning pin or a positioning hole) may be provided on the side of the clamping part 11 facing the supporting part 12. Correspondingly, a second positioning structure (e.g., a positioning hole or a positioning pin) corresponding to the first positioning structure may be provided on the side of the supporting part 12 facing the clamping part 11, so as to ensure the positioning accuracy of both the clamping part 11 and the supporting part 12.

[0062] Preferably, the clamping part 11 and the supporting part 12 can be magnetically fixed together (for example, a first magnetic element is provided on the side of the clamping part 11 facing the supporting part 12, and a second magnetic element is provided on the side of the supporting part 12 facing the clamping part 11, and the clamping part 11 and the supporting part 12 are magnetically fixed together by the attraction of the first magnetic element and the second magnetic element), so as to facilitate the loading and unloading of the clamping part 11 and the supporting part 12.

[0063] Preferably, such as Figure 3 As shown, in the first direction F1, the thickness of the clamping part 11 on the side near the driving member 112 is greater than the thickness of the clamping part 11 on the side near the battery clamping slot, so that a clamping groove is formed on the side of the clamping part 11 facing away from the first open opening 113 near the battery clamping slot. The supporting part 12 can be disposed in the clamping groove so that the bottom surface of the supporting part 12 is flush with the bottom surface of the clamping part 11 on the side near the driving member 112. In this way, not only is the deformation resistance of the clamping part 11 guaranteed and the arrangement space of the supporting part 12 is saved, but the flatness of the side of the clamping body 1 on the side of the supporting part 12 is also guaranteed, which is convenient for fixing and placing the clamping body 1.

[0064] Preferably, such as Figures 1 to 9As shown, the clamping body 1 includes multiple battery fixing components, which can be spaced apart along the third direction F3 on the clamping body 1 so that the battery assembly fixture can clamp multiple batteries 5 to be processed at the same time, thereby further improving the battery assembly efficiency.

[0065] In an embodiment, such as Figure 1 , Figure 2 and Figures 6 to 9 As shown, the battery mounting assembly may further include a positive nickel sheet positioning part 2. The positive nickel sheet positioning part 2 is detachably connected to the side of the first opening 113 of the clamping body 1. The positive nickel sheet positioning part 2 is provided with a positive nickel sheet positioning hole 21 that penetrates the positive nickel sheet positioning part 2 along the second direction F2. When the positive nickel sheet positioning part 2 is set in the clamping body 1, the positive nickel sheet positioning hole 21 is correspondingly set with the first opening 113 so that the positive nickel sheet 51 is set in the designated position of the battery 5 to be processed through the positive nickel sheet positioning hole 21. In this way, the positive nickel sheet 51 mounting process is realized through the positive nickel sheet positioning part 2.

[0066] It should be noted that the above-mentioned positive electrode nickel sheet positioning hole 21 can be adapted to the shape of the above-mentioned positive electrode nickel sheet 51. When the positive electrode nickel sheet positioning part 2 is fixed to the clamping body 1, the positive electrode nickel sheet positioning part 2 blocks the above-mentioned first open opening 113, so that only the part on the side where the positive electrode of the battery to be processed is located is exposed by the positive electrode nickel sheet positioning hole 21. Then, the positive electrode nickel sheet 51 can be placed through the positive electrode nickel sheet positioning hole 21, so that the positive electrode nickel sheet 51 and the battery to be processed can be accurately positioned.

[0067] Optionally, the positive electrode nickel sheet positioning part 2 and the clamping part 11 can also be magnetically fixed to achieve a detachable connection between the positive electrode nickel sheet positioning part 2 and the clamping part 11. The magnetic fixing of the positive electrode nickel sheet positioning part 2 and the clamping part 11 can be similar to the magnetic fixing of the clamping part 11 and the supporting part 12, and will not be described in detail here.

[0068] Optionally, the positioning structure of the above-mentioned positive electrode nickel sheet positioning part 2 and the above-mentioned clamping part 11 is similar to the positioning structure of the above-mentioned clamping part 11 and the supporting part 12 (that is, the cooperation between the first positioning structure and the second positioning structure) to achieve accurate positioning of the positive electrode nickel sheet positioning part 2 and the above-mentioned clamping part 11, which will not be described in detail here.

[0069] Preferably, such as Figure 1 As shown, the above-mentioned positive electrode nickel sheet positioning part 2 may also be provided with a drive groove 22 that extends through itself along the second direction F2. The actuating protrusion of the above-mentioned clamping part 11 can extend through the drive groove 22 to avoid the positive electrode nickel sheet positioning part 2 interfering with the driving of the clamping member 111.

[0070] Correspondingly, such as Figure 1 and Figure 2 As shown, the number of the above-mentioned positive electrode nickel sheet positioning holes 21 and driving grooves 22 can be equal to the number of the above-mentioned battery fixing components, and the above-mentioned positive electrode nickel sheet positioning holes 21 can correspond one-to-one with the first opening 113 of the battery fixing component, and the above-mentioned driving grooves 22 can correspond one-to-one with the clamping components 111 of the battery fixing component.

[0071] In an embodiment, such as Figure 1 and Figure 2 As shown, the battery mounting assembly may further include a welding block 3, which is detachably connected to the side of the positive nickel sheet positioning part 2 facing away from the clamping body 1. The welding block 3 is provided with a pressing protrusion 31, which protrudes along the second direction F2 toward the side where the positive nickel sheet positioning part 2 is located. When the welding block 3 is positioned on the positive nickel sheet positioning part 2, the pressing protrusion 31 can extend into the positive nickel sheet positioning hole 21 and abut against the positive nickel sheet 51. Thus, through the pressing action of the pressing protrusion 31, the positive nickel sheet 51 can be tightly fitted to the positive electrode of the battery 5 to be processed, ensuring the welding quality between the positive nickel sheet 51 and the positive electrode of the battery 5 to be processed, and preventing incomplete or missing welds. Furthermore, the welding block 3 can also be provided with a first weld point positioning hole 32 that penetrates the welding block 3 along the second direction F2. In this way, by blocking the above-mentioned positive electrode nickel sheet positioning hole 21 by the welding block 3, the welding point position of the positive electrode nickel sheet 51 can be exposed through the first weld point positioning hole 32. This not only achieves accurate positioning of the welding point position of the positive electrode nickel sheet 51, but also effectively avoids the non-welding point positions of the battery 5 to be processed from being exposed and damaged by the welding equipment.

[0072] Optionally, the positive electrode nickel sheet positioning part 2 and the welding pressure block 3 can also be magnetically fixed together. This achieves a detachable connection between the positive electrode nickel sheet positioning part 2 and the welding pressure block 3, and through the combined effect of the magnetic attraction between the positive electrode nickel sheet positioning part 2 and the welding pressure block 3 and the weight of the welding pressure block 3, the pressing protrusion 31 presses the positive electrode nickel sheet 51. The magnetic fixing of the positive electrode nickel sheet positioning part 2 and the welding pressure block 3 can be similar to the magnetic fixing of the clamping part 11 and the supporting part 12, and will not be described in detail here.

[0073] Optionally, the positioning structure of the above-mentioned positive electrode nickel sheet positioning part 2 and the above-mentioned welding pressure block 3 is similar to the positioning structure of the above-mentioned clamping part 11 and the supporting part 12 (that is, the cooperation between the first positioning structure and the second positioning structure) to achieve accurate positioning of the positive electrode nickel sheet positioning part 2 and the above-mentioned welding pressure block 3, which will not be described in detail here.

[0074] In an embodiment, such as Figure 1 , Figure 2 , Figure 4 , Figure 8 and Figure 9 As shown, the battery mounting assembly may further include a negative electrode solder joint positioning part 4, which is detachably connected to the side of the clamping body 1 where the operation port 115 is located (i.e., the end face of the clamping body 1 at one end in the second direction F2). The negative electrode solder joint positioning part 4 is provided with a second solder joint positioning hole 41, which penetrates the negative electrode solder joint positioning part 4 along the first direction F1. When the negative electrode solder joint positioning part 4 is set in the clamping body 1, the second solder joint positioning hole 41 is correspondingly set with the operation port 115. In this way, by blocking the operation port 115 through the negative electrode solder joint positioning part 4, the welding point position of the negative electrode nickel sheet 52 can be exposed through the second solder joint positioning hole 41. This not only achieves accurate positioning of the welding point position of the negative electrode nickel sheet 52, but also effectively avoids the exposure of the non-welding point position of the battery 5 to be processed and its damage to the welding equipment.

[0075] Optionally, the negative electrode solder joint positioning part 4 and the clamping body 1 can also be magnetically fixed to achieve a detachable connection between the negative electrode solder joint positioning part 4 and the clamping body 1. The magnetic fixing between the negative electrode solder joint positioning part 4 and the clamping body 1 can be similar to the magnetic fixing between the clamping part 11 and the supporting part 12, and will not be described in detail here.

[0076] Optionally, the positioning structure of the negative electrode solder joint positioning part 4 and the clamping body 1 is similar to the positioning structure of the clamping part 11 and the supporting part 12 (i.e., the cooperation between the first positioning structure and the second positioning structure) to achieve accurate positioning of the negative electrode solder joint positioning part 4 and the clamping body 1. This will not be elaborated further here.

[0077] In an embodiment, preferably, the battery assembly fixture may further include a first positioning base 61, on which the battery placement assembly may be disposed, so as to place the battery placement assembly on the corresponding equipment of the battery assembly system via the first positioning base 61. Specifically, as shown... Figure 6 and Figure 7 As shown, the first positioning base 61 can be positioned on the side of the battery mounting assembly facing away from the first opening 113 in the second direction F2. The first positioning base 61 is provided with a first slot 610, and the battery mounting assembly is detachably engaged with the first slot 610.
