[0051] Please see Figure 1 As shown, this embodiment provides a battery conductive strip welding fixture, including:
[0052] A mounting base 1 is provided, on which a mounting platform is provided for supporting the battery 4, and the battery 4 is initially positioned.
[0053] Positioning component 2 is fastened to the top of battery 4. Positioning component 2 is provided with mounting slots 23 for mounting the first polar conductive strip 5 and the second polar conductive strip 6, and the first polar conductive strip 5 and the second polar conductive strip 6 are separated by a gap 24.
[0054] The pressing component 3 is mounted on the positioning component 2 to press the conductive strip tightly against the battery 4 terminal. The pressing component 3 can be connected to an external vacuum cleaner through a vacuum pipe to suck up the dust generated during welding.
[0055] Specifically, in this embodiment, the mounting base 1 is installed on the equipment linear module platform, double-speed chain, belt, etc. The mounting base 1 provides a mounting platform for the battery 4, and the battery 4 is initially positioned. By setting the positioning component 2 on the top of the battery 4, the battery 4 is automatically and accurately positioned after initial positioning with the help of external equipment. The conductive strip is pressed by the set pressing component 3 to fit onto the battery 4 terminal. Then, the conductive strip is welded to the battery 4 with welding equipment. At the same time, the dust generated at the welding position is absorbed by the dust collection equipment to ensure the cleanliness of the site environment.
[0056] This embodiment describes a welding fixture for conductive strips on a battery 4. The battery 4 is initially positioned using a base 1, and then precisely positioned using positioning components. Simultaneously, a pressing component 3 presses the conductive strip firmly against the battery 4. Finally, welding equipment is used to weld the conductive strip to the battery 4. This fixture can automatically position, install, clamp, and weld the conductive strip on the battery 4, thereby improving welding efficiency and yield, saving labor costs, and preventing short circuits due to contact between the positive and negative conductive strips, thus reducing the occurrence of safety accidents.
[0057] In some implementations, such as Figure 1 and Figure 2 As shown, the mounting base 1 includes a base plate 11 and a mounting sleeve 12 disposed on the base plate 11;
[0058] The substrate 11 is detachably connected to an external device, and the substrate 11 is provided with a through hole 13 communicating with the mounting sleeve 12;
[0059] The inner diameter of the mounting sleeve 12 corresponds to the outer diameter of the battery 4.
[0060] Specifically, the mounting base 1 is integrally manufactured or separately assembled from a base plate 11 and a mounting sleeve 12. The base plate 11 has connection holes 27 for easy installation with the linear module platform, speed-up chain, belt, etc. of the equipment. The battery 4 is placed in the mounting sleeve 12. The mounting sleeve 12 is used for the placement and initial positioning of the battery 4. At the same time, a circular through hole is provided in the mounting sleeve 12, which is applicable to both batteries with and without terminals 4. A strip-shaped, circular or other shaped annular through hole is provided on the bottom circumference of the mounting sleeve 12, mainly to reduce dust and impurities and facilitate cleaning.
[0061] In some implementations, such as Figures 3 to 6 As shown, the positioning component 2 includes a first positioning member 21 and a second positioning member 22 that cooperates with the first positioning member 21;
[0062] The upper end surfaces of the first positioning member 21 and the second positioning member 22 are each provided with a mounting groove 23 to mount the first polar conductive strip 5 and the second polar conductive strip 6.
[0063] The second positioning member 22 extends outward from the end near the battery 4 and has a partition 24 that blocks the contact between the first polar conductive strip 5 and the second polar conductive strip 6.
[0064] Specifically, in this embodiment, the first positioning member 21 and the second positioning member 22 are configured to be in a corresponding fastening structure. The first positioning member 21 and the second positioning member 22 cooperate to accurately position the battery 4 at the top. At the same time, placement slots 23 are opened on the two positioning members to provide placement slots for placing two polar conductive strips, thereby realizing the placement and positioning of the conductive strips. After fastening, the first positioning member 21 and the second positioning member 22 use the partition 24 to separate the first polar conductive strip 5 and the second polar conductive strip 6 to prevent the two polar conductive strips from contacting and short-circuiting.
[0065] It should be noted that the first polar conductive band 5 described in this embodiment is a positive conductive band, and the second polar conductive band 6 is a negative conductive band, which will not be described in further detail.
[0066] In some implementations, such as Figure 3 and Figure 4 As shown, the bottom end faces of the first positioning member 21 and the second positioning member 22 are respectively provided with inner grooves 25 corresponding to the outer diameter of the battery 4. The depth of the inner grooves 25 is less than the thickness of the positioning members. The first positioning member 21 and the second positioning member 22 are fastened to the top of the battery 4.
[0067] The first positioning component 21 is also provided with a clearance slot 26, which is connected to the inner groove 25.
[0068] like Figure 5 and Figure 6 As shown, the end face of the partition 24 near the battery 4 is concave, and the concave surface cooperates with the clearance slot 26 to avoid the battery 4 terminal.
[0069] The second positioning component 22 has a placement groove 23 that communicates with the inner groove 25 provided thereon.
[0070] Specifically, the positioning component described in this embodiment takes the form of a positioning block or a positioning plate. Two positioning blocks are used to clamp the top of the battery 4 to achieve precise positioning of the battery 4. The following explanation uses the positioning block as an example.
[0071] An inner groove 25 is provided at the bottom of the positioning block. The inner groove 25 is a semi-circular structure. The battery 4 can be accurately positioned by using the two semi-circular inner grooves 25 of the positive and negative positioning blocks. A partition 24 is provided on the negative positioning block to separate the positive and negative conductive strips and prevent the positive and negative conductive strips from short-circuiting.
[0072] In some embodiments, the inner groove 25 on the first positioning member 21 is provided with a tapered opening at one end near the battery 4.
[0073] Specifically, in this embodiment, a tapered opening is provided at the edge of the inner groove 25 to facilitate the positioning and installation of the battery 4.
[0074] In some implementations, such as Figures 3 to 6 As shown, the first positioning member 21 and the second positioning member 22 each have a connecting hole 27 for connecting to the drive mechanism, and the drive member drives the first positioning member 21 and the second positioning member 22 to perform opening and closing actions.
[0075] Specifically, the driving mechanism described in this embodiment is a pneumatic finger cylinder, which drives two positioning blocks to open and close, so as to clamp or release the two positioning blocks.
[0076] In some implementations, such as Figures 7 to 9 As shown, the pressing assembly 3 includes a first pressing member 31 and a second pressing member 32 detachably connected to the first pressing member 31;
[0077] The first pressing member 31 is correspondingly disposed on the first positioning member 21. The first positioning member 21 is provided with a first through hole 33 for welding the first polar conductive strip 5. The second pressing member 32 is correspondingly disposed on the second positioning member 22. The second positioning member 22 is provided with a second through hole 34 for welding the second polar conductive strip 6.
[0078] The bottom end face of the first pressing member 31 is provided with a first protrusion 35 for pressing the first polar conductive strip 5; the bottom end face of the second pressing member 32 is provided with a second protrusion 36 for pressing the second polar conductive strip 6.
[0079] An insulating pad 37 is also provided between the first pressing member 31 and the second pressing member 32.
[0080] Specifically, in this embodiment, the first pressing member 31 is a positive pressing member, and the second pressing member 32 is a negative pressing member. The following explanation uses the positioning block as an example.
[0081] The positive and negative electrode pressing components are connected and assembled by fastening bolts. The connection holes 27 for installing the fastening bolts should be far away from the welding position so as not to obstruct normal welding work. At the same time, through holes are opened on each of the two pressing components to avoid the welding position of the conductive strip and to achieve welding. The bottom of the positive and negative electrode pressing components has U-shaped pressing protrusions to press the conductive strip and the battery four poles tightly together to ensure the welding effect. The insulating pad 37 set between the two pressing components is used to separate the positive and negative electrode pressing components when they are connected to prevent short circuit when the conductive strip is pressed.
[0082] In some implementations, such as Figures 7 to 9 As shown, the inner walls of the first through hole 33 and the second through hole 34 are both provided with dust suction holes 38 for connecting to the dust suction pipe.
[0083] Specifically, a dust suction hole 38 is provided on the inner circumference of the through hole, leading to the outside of the downward pressing component, for connecting a dust suction pipe. The dust suction pipe is connected to a dust suction pump to suck away the dust generated during welding.
[0084] In some implementations, such as Figure 10 As shown, the first pressing member 31 and the second pressing member 32 are fixedly connected by fastening bolts, and an insulating sleeve 39 is also fitted on the fastening bolts.
[0085] Specifically, the positive electrode pressing component and the negative electrode pressing component are combined by fastening bolts. The opening is used to avoid the welding position of the negative electrode conductive strip to achieve welding. The insulating sleeve 39 is used to disconnect the insulation when the positive and negative electrode pressing components are connected by fastening bolts to prevent short circuit.
[0086] In some implementations, such as Figure 7 and Figure 8 As shown, the first pressing member 31 has a mounting hole 310 connected to the pressing mechanism, and the pressing mechanism can control the two pressing members to press the conductive strip accordingly.
[0087] Specifically, the pressing mechanism described in this embodiment uses a cylinder or servo motor as a driving source, and the pressing component has a connection hole 27 for mounting the cylinder or servo motor, which facilitates the pressing head pressing up and down to tighten and loosen the conductive strip.
[0088] In practice, the automatic welding process of the conductive strip after the equipment is installed with the tooling fixture is as follows:
[0089] like Figures 11 to 15 As shown, when the first positioning component 21 and the second positioning component 22 are opened, the battery 4 is installed onto the mounting base 1. After the battery 4 is placed, the first positioning component 21 and the second positioning component 22 are closed by the pneumatic finger cylinder. After the battery 4 is positioned, the positive and negative conductive strips are placed. After the conductive strips are placed, the first pressing component 31 and the second pressing component 32 are controlled to press down and tighten the conductive strips. Welding is performed on the tightened conductive strips. After welding is completed, the pressing component 3 is controlled to lift up, the positioning component 2 is opened, and the welded battery 4 can be taken out.
