Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and more specifically, to a tooling for preventing errors in laser filler welding of battery modules. Background Technology

[0002] A certain percentage of laser welding failures occur during the manufacturing process of battery products (when bubbles inside the liquid aluminum metal burst and solidify rapidly, a circular pit is formed on the weld surface). In this case, it is necessary to manually fill the weld hole with metal auxiliary material and re-weld. The specific operation involves cutting and clamping the aluminum alloy material with pliers and placing it into the pit, and then using a laser to melt it and fill the pit to repair the defect.

[0003] However, during this process, due to the close proximity of adjacent cells, there is a chance that the metal filler or tools used during the filling process may come into contact with the positive and negative terminals of adjacent batteries, causing a short circuit, sparking, or even fire. Therefore, we have proposed a fault-prevention tooling for laser filler welding of battery modules. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a tooling for preventing errors in laser filler welding of battery modules, which can protect the terminals of adjacent battery modules.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A fault-prevention tooling for laser filler welding of battery modules includes a tooling sleeve and a battery module. The tooling sleeve is slidably fitted onto the outside of the battery module. A welding window is opened inside the tooling sleeve. A fixed shaft is fixedly connected to the inner side of the welding window. A buckle is rotatably connected to the outer side of the fixed shaft, and the position of the buckle corresponds to the welding window. A quick opening and closing mechanism is provided on the top of the tooling sleeve, and an auxiliary clamping mechanism is provided on the side of the tooling sleeve.

[0007] In a preferred embodiment of this invention, a spacer is fixedly connected to the top inner side of the tooling sleeve, and the spacer is in contact with the battery module. The spacer serves to separate the battery modules.

[0008] In a preferred embodiment of this utility model, the quick-opening and closing mechanism includes a mounting base fixedly connected to the top of the tooling sleeve. A cover is snapped into the mounting base. A locking pin is slidably connected inside the mounting base and is inserted into the cover. A ramp block is fixedly connected to one end of the locking pin inside the mounting base. A fixing rod is fixedly connected to the inner wall of the mounting base and slidably connected to the ramp block. A spring is installed inside the ramp block; one end of the spring is fixedly connected to the fixing rod, and the other end is fixedly connected to the inner surface of the ramp block. A push rod is slidably connected to the top of the mounting base and extends through the mounting base. A ball head is fixedly connected to one end of the push rod inside the mounting base, and the ball head abuts against the ramp block. A button is fixedly connected to the other end of the push rod. By pushing the push rod with the button, the ball head at the end of the push rod applies a downward pushing force to the ramp block, which then moves laterally under the guidance of the fixing rod. This controls the engagement and disengagement between the locking pin and the cover, allowing the cover to be opened quickly and exposing the welding window.

[0009] In a preferred embodiment of this invention, a protective sleeve is fixedly connected to the bottom edge of the button, and the protective sleeve is fixedly connected to the mounting base. The protective sleeve provides dust protection for the relative sliding area between the push rod and the mounting base.

[0010] In a preferred embodiment of this utility model, the auxiliary clamping mechanism includes a connecting frame fixedly connected to the side of the tooling sleeve. A hollow shell is fixedly connected to the end of the connecting frame. A rubber pad is slidably connected to the side of the hollow shell near the battery module, and the rubber pad penetrates the hollow shell and contacts the battery module. A pressure sleeve is slidably connected to the inner side of the hollow shell. One side of the pressure sleeve is fixedly connected to the rubber pad, and an adjusting rod is mounted on the other side of the pressure sleeve via a bearing. The adjusting rod penetrates the hollow shell and is threadedly connected to the hollow shell. A knob is fixedly connected to the end of the adjusting rod, and the outer wall of the hollow shell is fixedly connected to the pressure sleeve. An oil sleeve is fixedly connected, and a sponge block is slidably connected inside the oil sleeve. A baffle and a pressure plate are respectively in contact with the left and right sides of the sponge block, and the baffle and pressure plate are slidably connected to the inner side of the oil sleeve. A pusher is fixedly connected to the pressure plate, penetrating the oil sleeve and slidably connected to it. A threaded sleeve is threadedly connected to the outer side of the oil sleeve, abutting against the pusher. A second spring is installed inside the oil sleeve; one end of the second spring is fixedly connected to the baffle, and the other end is fixedly connected to the inner surface of the oil sleeve. An oil outlet hole is opened on the inner wall of the oil sleeve, and the position of the oil outlet hole corresponds to the position of the baffle. By rotating the adjustment rod with a knob, the adjustment rod generates lateral displacement through the threaded movement between it and the hollow shell. Subsequently, the adjustment rod drives the pressure sleeve, and the pressure sleeve applies pressure to the rubber gasket. This increases the friction between the tooling sleeve and the battery module, ensuring the stability of the installation.

[0011] In a preferred embodiment of this invention, the side of the pressure sleeve is provided with ball bearings, and the ball bearings are in contact with the inner surface of the hollow shell. The ball bearings reduce the relative friction between the pressure sleeve and the hollow shell.

[0012] In a preferred embodiment of this invention, a guide rod is fixedly connected to the inner wall of the hollow shell, the guide rod passing through the pressure sleeve and slidably connected to the pressure sleeve. The guide rod guides the lateral movement of the pressure sleeve.

[0013] As a preferred embodiment of this utility model, the top edge of the tooling sleeve has two handles welded on it, and the handles are made of stainless steel. The handles facilitate the carrying of the tooling sleeve as a whole.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) In this utility model, a tooling sleeve is set up and fastened to each battery module. The tooling sleeve is provided with multiple welding windows. The number and position of the welding windows correspond to the terminals of each battery module. Then, a flip-up cover is set at the welding window and a corresponding quick opening and closing mechanism is set. When it is necessary to repair welding on the terminal of a battery module, the push rod is pushed by the button, so that the ball head at the end of the push rod applies a downward force to the inclined block. The inclined block moves laterally under the guidance of the fixed rod, thereby controlling the engagement and disengagement between the locking pin and the cover. The cover can be opened quickly and the welding window is exposed. Then, the repair welding can be performed without affecting the terminals of other battery modules.

[0016] (2) In this utility model, two sets of auxiliary clamping mechanisms are provided on the side of the tooling sleeve. The adjusting rod is rotated by the knob, and the adjusting rod generates a lateral displacement through the threaded movement between the adjusting rod and the hollow shell. Then the adjusting rod drives the pressure sleeve and applies pressure to the rubber pad through the pressure sleeve. This can increase the friction between the tooling sleeve and the battery module and ensure the stability of the installation. Attached Figure Description

[0043] In this embodiment, the guide rod 78 guides the lateral movement of the pressure sleeve 74.

[0044] Working principle: In use, first, the tooling sleeve 1 is placed on top of each battery module 2 using the handle 6. Then, the adjusting rod 76 is rotated by the knob 77. The adjusting rod 76 generates lateral displacement through the threaded movement between it and the hollow shell 72. Then, the adjusting rod 76 drives the pressure sleeve 74, and the pressure sleeve 74 applies pressure to the rubber pad 73. This increases the friction between the tooling sleeve 1 and the battery modules 2, ensuring the stability of the installation. When it is necessary to repair the welding of a terminal of a battery module 2, simply push the push rod 56 by the button 58. This causes the ball head 57 at the end of the push rod 56 to apply a downward pushing force to the inclined block 53. The inclined block 53 moves laterally under the guidance of the fixing rod 54, thereby controlling the engagement and disengagement between the locking pin 52 and the cover 4. This allows the cover 4 to be opened quickly, exposing the welding opening 101, and then the repair welding can be performed without affecting the terminals of other battery modules 2.
