Description

Technical Field

[0002] In lithium-ion batteries, the adapter is a component used to connect the electrode column and the pole ear. During assembly, the adapter and the pole ear usually need to be welded. In the existing process, before the pole ear and the adapter are welded, the adapter needs to be transferred to the positioning fixture in the welding fixture, and then the battery cell is moved to the welding fixture by a mechanical clamp, and welding is performed after positioning is completed. Among them, when the welding fixture reaches the loading position of the adapter, the loading nozzle needs to move the adapter from the secondary positioning platform to the adapter fixture in the welding fixture, and then the battery cell is moved to the welding fixture. The above operation process requires mechanical grippers to frequently move the battery cells, which can easily cause appearance damage to the battery cells (such as battery cell powder loss, battery cell collision, etc.), affecting the assembly consistency of the battery cells and the quality of battery products; at the same time, the traditional adapter fixture cannot be directly fixed to the welding fixture, and it is difficult to ensure the consistency of assembly accuracy between multiple fixtures, which can easily produce large installation errors and lead to poor quality phenomena such as skewness of the welded adapter, and the adapter loading steps are relatively cumbersome, affecting the production efficiency of the welding operation.

[0035] In the description of the application, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically limited. In the embodiment of the present application, all directional indications (such as up, down, left, right, front, back, top, bottom ...) are only used to explain the relative position relationship, motion conditions, etc. between the components under a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their deformations are intended to cover non-exclusive inclusions. For example, the process, method, system, product or equipment comprising a series of steps or units are not limited to the steps or units listed, but optionally also include the steps or units not listed, or optionally also include other steps or units inherent to these processes, methods, products or equipment.

[0036] In addition, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] The following provides some embodiments of the adapter jig, adapter feeding device and battery production equipment in the technical solution of the utility model.

[0039] In an embodiment of the first aspect of the present utility model, a transfer sheet fixture 100 is provided, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a jig base 1 and a jig body 2. A first through hole 10 is provided on the jig base 1, and a first positioning component 11 is also provided on the jig base 1, which is used to position and connect with the welding device when performing the adapter plate feeding operation. The jig body 2 is detachably connected to the jig base 1, and an adapter plate positioning groove 21 is provided on the side of the jig body 2 away from the jig base 1, which is used to install the adapter plate during the feeding operation; the adapter plate positioning groove 21 is arranged corresponding to the first through hole 10, and a second through hole 211 that penetrates the first through hole 10 is provided in the adapter plate positioning groove 21, so as to reserve space for the adapter plate welding operation, and the welding component can pass through the first through hole 10 and the second through hole 211 to perform welding operations on the adapter plate.

[0040] In practical applications, such as Figure 1 In the example, the jig body 2 is installed above the jig base 1. During the adapter welding operation, the adapter jig 100 carrying the adapter can be moved under the drive of the loading device, and directly positioned and assembled with the welding device through the first positioning component 11. The battery cell only needs to be moved once to perform the welding operation with the adapter, and the consistency of the assembly accuracy can be improved; when the adapter is changed, there is no need to replace the adapter jig 100 as a whole, and only the jig body 2 that matches the specifications of the adapter needs to be replaced separately.

[0041] It is understandable that in the existing adapter welding process, the battery cell usually needs to be moved multiple times, which can easily cause damage to the surface of the battery cell. In addition, the existing adapter jig and welding fixture cannot be directly fixed, making it difficult to ensure the consistency of assembly accuracy between multiple jigs.

[0042] The adapter jig 100 in the present embodiment improves the assembly method of the structure, so that the adapter jig 100 can be directly fixed to the welding fixture, reducing the number of times the battery cell is moved, thereby improving the consistency of assembly accuracy between multiple jigs, reducing the possibility of poor quality due to assembly errors, and simplifying the adapter loading steps, which is beneficial to improving the production efficiency of the welding operation. Moreover, when the product is changed, the corresponding jig body 2 can be replaced separately according to the different specifications of the adapter, which is beneficial to saving replacement time and cost.

[0043] It should be noted that the number of the adapter plate positioning grooves 21 on the fixture body 2 is not limited to Figure 1 The two shown in the figure can also be set to one or more than two, and can be set according to production needs. The welding device can be an ultrasonic welding machine.

[0044] In a further embodiment of the present invention, Figures 1 to 3 As shown, the first positioning assembly 11 includes a first positioning pin 111; the first positioning pin 111 is arranged on the side of the fixture base 1 facing the fixture body 2, and as shown Figure 3 and Figure 4 In the example, the fixture base 1 is provided with first positioning pins 111 at both ends in the first direction. Figure 5 and Figure 6 As shown, a first pin hole 22 is provided on the jig body 2 at a position corresponding to the first positioning pin 111, and each first positioning pin 111 passes through a corresponding first pin hole 22 and passes out from the side of the jig body 2 away from the jig base 1, so that the end of the first positioning pin 111 is exposed. During the loading operation, the exposed portion of the first positioning pin 111 can be positioned and connected with the welding shield of the welding device to achieve positioning and assembly between the adapter jig 100 and the welding device, thereby improving the positioning accuracy and simplifying the loading process.

[0045] Furthermore, if Figures 1 to 4 As shown, the first positioning assembly 11 also includes a second positioning pin 112 and a positioning magnet 113 provided on the jig base 1. In a second direction perpendicular to the first direction, the second positioning pin 112 and the positioning magnet 113 are respectively located on both sides of the jig body 2; when performing the adapter sheet feeding operation, the second positioning pin 112 is used to be positioned and connected with the welding fixture of the welding device, and the positioning magnet 113 is used to be adsorbed and connected with the welding fixture of the welding device, so that the adapter sheet jig 100 is fixed to the welding fixture. Among them, the number of the second positioning pin 112 and the positioning magnet 113 can be multiple; for example Figure 3 In the example, one second positioning pin 112 and one positioning magnet 113 that are arranged opposite to each other form a group, and multiple groups of second positioning pins 112 and positioning magnets 113 can be arranged at intervals in the first direction.

[0046] Preferably, the setting is Figure 3 The two groups of second positioning pins 112 and positioning magnets 113 are shown in the figure, and in the first direction, the two groups are respectively located near the two ends of the fixture base 1. More preferably, the positions of the second positioning pins 112 and the positioning magnets 113 in the two groups are opposite, that is, the two second positioning pins 112 are located on both sides of the fixture body 2 and are arranged diagonally, and the two positioning magnets 113 are also located on both sides of the fixture body 2 and are arranged diagonally. After being connected to the welding fixture, the force on both sides of the adapter fixture can be more evenly applied.

[0047] In a further embodiment of the present invention, Figure 3 and Figure 4 As shown, the fixture base 1 is provided with a fixture positioning groove 12, and the fixture positioning groove 12 is recessed in a direction away from the fixture body 2, that is, Figure 3 The height direction shown in FIG. is concave downward; Figure 3 and Figure 6As shown, the side of the jig body 2 facing the jig base 1 is provided with a protruding structure 23 whose shape matches the jig positioning groove 12. During assembly, the protruding structure 23 extends into the jig positioning groove 12 and forms a positioning match with the jig positioning groove 12. The positioning match between the protruding structure 23 and the jig positioning groove 12 can work together with the first positioning component 11 to form a double positioning, which can further improve the positioning accuracy between the jig body 2 and the jig base 1. Among them, the jig positioning groove 12 is not limited to Figure 3 The shape structure shown in the figure can also adopt other shape structures according to specific assembly requirements.

[0048] Preferably, if Figure 3 As shown, in the second direction, both ends of the jig positioning groove 12 are through structures, and in the first direction, the side walls of both ends of the jig positioning groove 12 are arcuate structures. Correspondingly, both ends of the protruding structure 23 in the first direction are also arcuate structures with the same curvature. The arcuate structure can be used to guide when the protruding structure 23 cooperates with the jig positioning groove 12, thereby reducing the difficulty of assembly.

[0049] Furthermore, in a specific implementation, Figures 3 to 5 As shown, a plurality of jig positioning pins 121 are provided in the jig positioning groove 12 of the jig base 1, and correspondingly, a plurality of jig positioning holes 231 are provided at the bottom of the protruding structure 23 of the jig body 2; each jig positioning pin 121 corresponds to a jig positioning hole 231, forming a one-to-one correspondence, and each jig positioning pin 121 is inserted into the corresponding jig positioning hole 231 to further realize the assembly positioning between the jig body 2 and the jig base 1.

[0050] Furthermore, in another specific implementation, as Figure 7 As shown, a plurality of jig positioning holes 231 are provided in the jig positioning groove 12 of the jig base 1, and correspondingly, a plurality of jig positioning pins 121 are provided at the bottom of the protruding structure 23 of the jig body 2; each jig positioning pin 121 corresponds to a jig positioning hole 231, forming a one-to-one correspondence, and each jig positioning pin 121 is inserted into the corresponding jig positioning hole 231 to further realize the assembly positioning between the jig body 2 and the jig base 1.

[0051] It should be noted that the number of the fixture positioning holes 231 and the fixture positioning pins 121 can be set according to specific assembly requirements. Figure 3 and Figure 7 In the example in, four fixture positioning holes 231 and four fixture positioning pins 121 are provided and arranged in a rectangular array, so that the force is relatively uniform after assembly.

[0052] Furthermore, if Figure 3 and Figure 4As shown, on the fixture base 1, the fixture positioning groove 12 is located near the middle of the fixture base 1 in the first direction. Accordingly, first through holes 10 are provided on both sides of the fixture positioning groove 12 in the first direction. Figure 3 , Figure 5 and Figure 6 As shown, a plurality of adapter plate positioning grooves 21 are provided on the fixture body 2, and the plurality of adapter plate positioning grooves 21 are respectively located on both sides of the fixture positioning groove 12 in the first direction. Specifically, the area on the fixture body 2 opposite to the first through hole 10 is provided with an adapter plate positioning groove 21. Preferably, as Figure 3 In the example in FIG. 1 , two adapter plate positioning grooves 21 are provided on the fixture body 2 and are symmetrically arranged relative to the center line of the fixture body 2; two second through holes 211 are provided in each adapter plate positioning groove 21, and two first through holes 10 are correspondingly provided on the fixture base 1. The two first through holes 10 are respectively arranged opposite to and connected with the corresponding second through holes 211, so as to provide space for welding operation through the first through holes 10 and the second through holes 211 when the adapter plate is carried in the adapter plate positioning groove 21. Specifically, the first through holes 10 and the second through holes 211 can be used as follows: Figure 3 The rectangular hole shown in FIG.

[0053] Furthermore, if Figures 1 to 3 As shown, preferably, the fixture body 2 can be made of PEEK (polyetheretherketone), POM (polyoxymethylene), PEKC (phenolphthalein polyaryletherketone) or other polyaryletherketone materials. Such materials have both rigidity and toughness, are light in weight, have good mechanical properties, are not easy to deform, and are suitable for use in battery production processes. When the adapter is changed, only the fixture body 2 with a contoured positioning groove that matches the shape of the adapter needs to be replaced, which helps save replacement time and cost.

[0054] The first positioning pin 111 can be made of 6061 alloy, 7075 alloy or other high-strength alloys. Such materials have good formability, weldability and machinability, high material strength and good mechanical properties, which are conducive to avoiding the complete deformation of the stressed parts and causing quality problems of the product. The first positioning pin 111 is mainly used to fix the fixture body 2 and the fixture base 1, and can also provide a matching reference for the welding shield.

[0055] The jig base 1 can be made of Q235 steel or other high-strength alloy steel. The material has high strength and high mechanical properties, which can prevent the stressed parts from bending and deforming, causing quality problems in the product. The jig body 2 can provide a positioning reference for the jig body 2 through the jig positioning groove 12 and the jig positioning pin 121, and can also be positioned and matched with the welding fixture through the second positioning pin 112 and the positioning magnet 113. The first through hole 10 of the jig base 1 is compatible with the welding marks of various battery cells. When the adapter is changed, the jig base 1 does not need to be replaced.

[0056] Among them, the chamfer design of the adapter plate positioning groove 21 is above C1 (the chamfer is 45° and the length of the right-angle side is 1mm). When carrying the adapter plate, the adapter plate and the edge of the adapter plate positioning groove 21 need to be fixed at a spacing of 0.25mm to avoid overlapping when the adapter plate is placed. A hole for fixing the fixture positioning pin 121 is provided in the fixture positioning groove 12, and the positioning accuracy meets 0.02mm. The positioning magnet 113 can specifically adopt a conical magnet with a taper of 1:50 to facilitate assembly. It can achieve self-locking when subjected to lateral force. The positioning performance is good and can withstand multiple disassembly and assembly without affecting the connection. When used, it is fixed and positioned with the welding fixture through magnetic attraction. The second positioning pin 112 can be made of 45 steel or other high-strength alloy pins. The material must have high strength and good mechanical properties to avoid bending and deformation of the stressed parts, which may cause quality problems in the product. It is used for installation and coordination with the welding fixture to achieve fixed positioning.
