Description

Technical Field

[0002] The CCS (Cell contact system, the component for cell connection and voltage and temperature acquisition, hereinafter referred to as CCS) component is mainly used in new energy vehicles and serves as a component for collecting signals and controlling and managing each cell unit of the new energy battery management module. In the processing of the CCS component, a wire harness, an aluminum bar, and a nickel sheet need to be welded and assembled together. After the wire harness, the aluminum bar, and the nickel sheet are positioned by a welding and fixing jig, they are welded together by laser.

[0003] In the traditional welding and fixing jig, the wire harness is manually pressed into the clamping groove by hand. The clamping groove is too small and not convenient for assembly. When pulling the wire, it is even easy to cause the nickel terminal to loosen, posing a safety hazard. If the clamping groove is too large, there is no constraint on the wire harness in the vertical direction, which is likely to cause the nickel sheet to flip, and the nickel sheet on the wire harness cannot fit the aluminum bar, resulting in poor laser welding and welding quality problems (such as false welding, welding deviation, missing welding, etc.). Moreover, it is necessary to manually add tape for fixing and protection, and the assembly and positioning consistency is poor, and the production efficiency is low. Utility Model Content

The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more of the related listed items.

[0031] Please refer to Figures 1 to 4 , this application provides a CCS component welding and fixing device. The CCS component includes a wire harness 100, an aluminum row 200, and a nickel sheet 300. The CCS component welding and fixing device includes a base 10, a positioning groove 20, and a pressing member 30. Among them, the positioning groove 20 is used to place and position the aluminum row 200. The base 10 has a length direction and a width direction, and the length direction and the width direction are arranged at an angle. A plurality of positioning grooves 20 are provided, and the plurality of positioning grooves 20 are spaced apart along the length direction of the base 10. A plurality of pressing members 30 are provided, and the plurality of pressing members 30 are provided in one-to-one correspondence with the plurality of positioning grooves 20.

[0032] Among them, the pressing member 30 includes a rotating shaft 31 and a pressing member 32. The rotating shaft 31 is arranged on the base 10, and the pressing member 32 is rotatably connected to the rotating shaft 31 around the rotating shaft 31. The pressing member 32 can cooperate with the positioning groove 20 to press the nickel sheet 300 onto the aluminum row 200.

[0033] It can be understood that during welding, a plurality of aluminum rows 200 are placed in a plurality of positioning grooves 20 one by one, the wire harness 100 is placed on the base 10, and a plurality of nickel sheets 300 on the wire harness 100 are placed on the plurality of aluminum rows 200 one by one. Then, manually pull the plurality of pressing members 32 one by one to press on the plurality of nickel sheets 300, and press the nickel sheet 300 to be welded and the aluminum row 200 at the corresponding position tightly. After the fixing work is completed, welding can be started.

[0034] In this way, through the cooperation of the positioning groove 20 and the pressing member 32, the nickel sheet 300 and the aluminum row 200 are positioned and pressed. The wire harness 100 only needs to be placed on the base 10. The complex operation of positioning the wire harness 100 is omitted, the operation process is simplified, and the processing efficiency is improved. The clamping groove of the wire harness 100 is cancelled, and the structure of the whole device is simpler, effectively reducing the cost.

[0035] Secondly, the pressing member 32 can ensure that the nickel sheet 300 and the aluminum row 200 are closely attached, the welding position is accurately positioned, the situation of flipping the nickel sheet 300 during welding is avoided, and the welding quality problems are not likely to occur.

[0036] Moreover, the pressing member 32 is rotatably arranged. By manually turning the pressing member 32 to rotate relative to the rotating shaft 31, the fixing of the position of the nickel sheet 300 can be controlled to be tightened or loosened, and the operation is fast. The rotation pressing range is wide, the situation of manual repeated operation to adjust the position is reduced, and the one-time welding and assembly operation is realized.

[0037] Furthermore, the positioning groove 20 includes a main body groove 21 and a secondary groove 22. Among them, the main body groove 21 is used to place and position the aluminum row 200. The secondary groove 22 is arranged on the side of the main body groove 21 and is communicated with the main body groove 21. The secondary groove 22 can be inserted by the operator's finger, which is convenient for taking and placing the aluminum row 200.

[0038] Exemplarily, two secondary grooves 22 are provided. Along the length direction of the base 10, the two secondary grooves 22 are respectively arranged on both sides of the main body groove 21. The left and right secondary grooves 22 can be inserted by fingers, making it more convenient to take and place the aluminum row 200.

[0039] Preferably, the secondary grooves 22 of two adjacent positioning grooves 20 are communicated with each other. The two secondary grooves 22 can be processed together, and the processing is simple.

[0040] Exemplarily, the secondary groove 22 is set to be square, and then a plurality of secondary grooves 22 and the main body groove 21 can be communicated with each other to form a long strip-shaped groove, which is convenient for processing and forming.

[0041] Furthermore, the rotating shaft 31 is fixedly connected to the base 10, and the pressing member 32 is sleeved on the rotating shaft 31 and can rotate relative to the rotating shaft 31. During the rotation process, a part of the pressing member 32 can enter the area where the positioning groove 20 is located.

[0042] Preferably, the pressing member 32 is a flexible structure. It has a certain deformation ability and can better press the nickel sheet 300.

[0043] Exemplarily, the rotating shaft 31 is a bolt, a rivet, etc. The pressing member 32 is made of materials such as rubber and resin to form a flexible structure.

[0044] In one embodiment, an extension portion 321 is provided on the pressing member 32. The extension portion 321 is provided on the side of the pressing member 32 away from the positioning groove 20 and protrudes from the top surface of the pressing member 32. That is, in the height direction, the extension portion 321 is provided on the top surface of the pressing member 32 and protrudes from the top surface of the pressing member 32.

[0045] Understandably, the presence of the extension portion 321 increases the overall height of the pressing member 32. Then, the operator can push the extension portion 321 to lever the pressing member 32, more easily avoiding the aluminum row 200 in the positioning groove 20 and preventing accidental contact with the aluminum row 200 from affecting the positioning position.

[0046] In one embodiment, the CCS component welding and fixing device further includes an auxiliary pressing member 40. Among them, a plurality of auxiliary pressing members 40 are provided, and the plurality of pressing members 30 are arranged in one-to-one correspondence with the plurality of positioning grooves 20 for pressing the aluminum row 200 in the positioning groove 20. That is, the auxiliary pressing member 40 and the pressing member 32 will synchronously press the aluminum row 200, making the position positioning more accurate.

[0047] Preferably, the structure of the auxiliary pressing member 40 is set to be the same as that of the pressing member 30, reducing the types of parts and lowering the manufacturing cost of the device.

[0048] Furthermore, the CCS component welding and fixing device further includes a wire harness positioning member 50. The positioning member can abut against the wire harness 100 for positioning the position of the wire harness 100 on the base 10.

[0049] Understandably, using the positioning member to position the wire harness 100 further improves the accuracy of the welding position of the nickel sheet 300 and the aluminum row 200.

[0050] Furthermore, the wire harness positioning member 50 is provided on the pressing member 32, and the wire harness positioning member 50 extends from the pressing member 32 towards the base 10.

[0051] Optionally, the lower bottom surface of the wire harness positioning member 50 extends to the upper surface of the base 10. That is, the wire harness positioning member 50 abuts against the base 10. Ensure that the wire harness 100 will not get stuck in the gap between the wire harness positioning member 50 and the base 10.

[0052] Preferably, the wire harness positioning member 50 and the pressing member 32 are of an integrally formed structure. Simplify the parts of the device and reduce the manufacturing cost of the device.

[0053] Exemplarily, the integral forming can be obtained by injection molding, compression molding, cutting and other methods.

[0054] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0055] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
