Description

Technical Field

[0001] This utility model belongs to the technical field of soldering equipment, specifically relating to a soldering device for a lithium battery BMS protection board. Background Technology

[0002] The BMS (Battery Management System) protection board of lithium batteries plays a crucial role in the safe use and performance of lithium batteries, and the soldering process in its production directly affects the quality and stability of the product.

[0003] A soldering device for a lithium battery protection board, disclosed in CN216291660U, relates to the technical field of soldering devices. It includes a soldering table with two sets of U-shaped frame plates symmetrically arranged on its upper outer surface. A waste residue trough is provided between the two sets of U-shaped frame plates. A protective frame is provided on the upper outer surface of the waste residue trough. The soldering table is located on the upper outer surface of a support column. A support base plate is provided on the lower outer surface of the support column. A self-locking caster wheel is provided on the lower outer surface of the support base plate. An adjusting cylinder is provided on the upper outer surface of the support base plate.

[0004] The aforementioned device can hold the protection board down to prevent it from shaking. However, when soldering the BMS protection board, the high temperature generated by the solder will cause the flux and other substances to vaporize and form fumes. After the fumes come into contact with the air, they condense into dust particles. Due to the lack of effective fume and dust treatment measures, workers are very likely to inhale these harmful particles when operating at close range, which can seriously damage the respiratory system and affect their health. At the same time, untreated fume and dust will also pollute the workshop and the surrounding environment, which does not meet the requirements of environmentally friendly production. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing technologies cannot block fumes during soldering operations on BMS protection boards, causing fumes to condense into dust particles that float in the air and are inhaled by workers, affecting their health. Therefore, this invention proposes a soldering device for lithium battery BMS protection boards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A soldering device for a lithium battery BMS protection board includes a soldering station and a vacuum cleaner. A fume hood is mounted on the upper surface of the soldering station. Two observation glasses are installed inside the fume hood. An exhaust pipe is fixedly connected to the exhaust end of the vacuum cleaner, and a suction head is fixedly connected to one end of the exhaust pipe. The outer surface of the suction head is fixedly connected to the fume hood. Two sets of symmetrical shielding curtains are fixedly connected inside the fume hood.

[0008] Preferably, the upper surface of the soldering station has two guide slots, and two limiting mechanisms are provided above the soldering station. The limiting mechanism includes a limiting frame, and the outer surface of the limiting frame is slidably connected to the two guide slots respectively.

[0009] Preferably, the limiting frame has an internal threaded connection to a threaded rod, the bottom end of which is rotatably connected to a pressure block, and a rubber pad is installed on the bottom surface of the pressure block.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A soldering device for a lithium battery BMS protection board includes a soldering station 1 and a vacuum cleaner 4. The upper surface of the soldering station 1 is equipped with a fume hood 2. The inside of the fume hood 2 is equipped with two observation glasses 3. The fume hood 2 can form a semi-enclosed space to effectively block the spread of solder fumes. The observation glasses 3 make it easy for workers to observe the soldering process.

[0024] The vacuum cleaner 4 has a fixed suction pipe 5 at its suction end, and a suction head 6 at one end of the suction pipe 5. The outer surface of the suction head 6 is fixedly connected to the smoke shield 2. The vacuum cleaner 4 can remove smoke in time through the suction pipe 5 and the suction head 6 to ensure a clean working environment.

[0025] The smoke hood 2 has two sets of symmetrical shielding curtains 7 fixedly connected inside. The upper surface of the smoke hood 2 is fixedly connected to a power supply wire 8. One end of the power supply wire 8 is connected to a soldering iron 9. The shielding curtains 7 can fit the arm to reduce smoke leakage. One end of the power supply wire 8 is connected to an external power supply, and the other end supplies power to the soldering iron 9 for soldering operations.

[0026] Two guide slots 11 are provided on the upper surface of the soldering station 1, and two limiting mechanisms 14 are provided above the soldering station 1. The limiting mechanism 14 includes a limiting frame 1406. The outer surface of the limiting frame 1406 is slidably connected to the two guide slots 11 respectively. The guide slots 11 provide sliding tracks for the limiting mechanism 14 to ensure its smooth and accurate movement.

[0027] One of the guide slots 11 is equipped with a bidirectional lead screw 13. One end of the bidirectional lead screw 13 passes through the soldering station 1 and extends to the outside of the soldering station 1. The bidirectional lead screw 13 is rotatably connected to the soldering station 1 and the inner wall of one of the guide slots 11. The bidirectional lead screw 13 is threadedly connected to two limit frames 1406 respectively. One end of the bidirectional lead screw 13 is fixedly connected to a second turntable 12. Rotating the second turntable 12 can drive the two limit mechanisms 14 to move synchronously through the bidirectional lead screw 13, and quickly adjust to the position that can limit the BMS protection board.

[0028] The limit bracket 1406 has a threaded rod 1402 internally connected to it. The bottom end of the threaded rod 1402 is rotatably connected to a pressure block 1403. A rubber pad 1404 is installed on the bottom surface of the pressure block 1403. Rotating the threaded rod 1402 can drive the pressure block 1403 to press down. The rubber pad 1404 increases the friction to prevent the protective plate from sliding.

[0029] Two guide rods 1405 are fixedly connected to the upper surface of the pressure block 1403. The outer surfaces of the two guide rods 1405 are slidably connected to the limit frame 1406. The setting of the two guide rods 1405 can ensure that the pressure block 1403 is pressed down vertically, and avoid the BMS protection plate from deforming due to uneven force.

[0030] An external extension platform 15 is fixedly connected to the back of the soldering station 1. A carrier 10 is installed on the upper surface of the external extension platform 15. The vacuum cleaner 4 is installed on the carrier 10. The external extension platform 15 and the carrier 10 support the vacuum cleaner 4 and provide stable support for the air extraction system.

[0031] Working principle: Place the BMS protection board on the upper surface of the soldering station 1. Rotate the second turntable 12 to drive the bidirectional lead screw 13 to rotate. Since the threads at both ends of the bidirectional lead screw 13 turn in opposite directions, it can drive the limit frames 1406 of the two limit mechanisms 14 to move synchronously to both sides of the protection board along the guide slot 11 until the limit mechanism 14 is close to the edge of the protection board. Rotate the first turntable 1401 to drive the threaded rod 1402 to rotate. The threaded engagement between the threaded rod 1402 and the limit frame 1406 causes the pressure block 1403 to move downward. After the rubber pad 1404 contacts the surface of the protection board, it continues to tighten, and the protection board is fixed by friction.

[0032] The worker inserts their hand into the smoke shield 2 through the gap in the curtain 7. The curtain 7 hangs down naturally, fitting snugly against the arm, forming a side-enclosed space to reduce smoke leakage. The vacuum cleaner 4 is activated, creating negative pressure in the suction pipe 5. The vacuum head 6 draws the fumes generated by soldering inside the smoke shield 2 into the vacuum cleaner 4 through the suction pipe 5 for collection and further processing. The soldering iron 9 is powered by the power supply wire 8. The worker holds the soldering iron 9 and solder bars to perform soldering operations on the protection board. The observation glass 3 is used to observe the soldering process in real time.
