Description

Technical Field

[0001] This utility model belongs to the field of flying welding equipment for new energy battery packs, specifically involving the dust removal mechanism of a dust removal milling equipment for post-welding inspection of power battery packs. Background Technology

[0002] Current post-weld dust removal technology involves separate dust removal and testing at three different workstations, resulting in high costs, large footprint, and low production efficiency. It also leads to slow changeover times for compatible products, requiring manual changeovers. After dust removal, modules need time to be transferred to the next workstation for further processing. Multiple workstations make it difficult to control product yield and increase equipment maintenance and operating costs.

[0003] Therefore, a testing and milling module for a power battery pack post-weld inspection and dust removal milling equipment was designed, integrating post-weld dust removal, inspection, and milling into one station. (See [reference]). Figure 1 The invention includes a three-axis frame 1, a dust removal mechanism 2 fixed to the moving end of the three-axis frame 1, and a detection milling module 3. This patent focuses on the dust removal mechanism 2.

[0004] Existing dust removal equipment uses a motor to rotate and drive a brush that does not completely cover the battery pack for vacuum dust collection, resulting in unsatisfactory dust removal effects and incompatibility with multiple products. Utility Model Content

[0005] To address the issues of unsatisfactory dust removal performance and incompatibility with multiple products in existing dust removal equipment for post-fly welding of new energy battery packs, this utility model provides a dust removal mechanism for a power battery pack post-fly welding inspection and dust removal milling equipment. This mechanism offers excellent dust removal performance and is compatible with multiple products.

[0006] The technical solution of this utility model is as follows:

[0007] The dust removal mechanism of the power battery pack post-weld inspection dust removal milling equipment includes a connecting frame, and a dust removal hood, a brush and a roller brush disposed on the connecting frame. The dust removal hood has an opening at the bottom, the brush is hinged inside the dust removal hood and its bottom protrudes from the opening, and the brush is fixed to the bottom of the dust removal hood. The connecting frame is driven to move up and down by a first driving device, and the roller brush is driven to rotate by a second driving device.

[0008] Preferably, a dust removal negative pressure pipe is also fixed on the connecting frame, the dust removal negative pressure pipe is connected to a negative pressure pump, and the dust removal negative pressure pipe is located on the rear side of the dust removal hood.

[0009] Preferably, the brushes are arranged around the bottom of the dust removal hood.

[0010] Preferably, the roller brush is made of nylon 66 and silicon carbide.

[0011] Preferably, the material of the roller brush is aluminum oxide.

[0012] Preferably, the first driving device is a slide cylinder, and the moving end of the slide cylinder is fixedly connected to the connecting frame.

[0013] Preferably, the second driving device is a motor, and the output end of the motor is fixedly connected to the roller brush.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The dust removal mechanism of the power battery pack post-weld inspection dust removal milling equipment designed in this utility model can easily clean the dust on the battery pack by designing a brush and a roller brush, and then remove the dust by suction through a dust removal negative pressure pipe, further improving the dust removal effect. The dust removal effect is good, and since the dust removal mechanism is set on a three-axis frame and a slide cylinder installed on it, the position of the dust removal can be easily adjusted, and it can be compatible with multiple products.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] See Figure 1-4 The dust removal mechanism of the power battery pack post-weld inspection dust removal milling equipment includes a connecting frame 4, and a dust removal hood 21, a brush 22 and a roller brush 23 disposed on the connecting frame 4. The dust removal hood 21 has an opening at the bottom, the brush 22 is hinged inside the dust removal hood 21 and its bottom protrudes from the opening, and the brush 22 is fixed to the bottom of the dust removal hood 21. The connecting frame 4 is driven to move up and down by a first driving device, and the roller brush 23 is driven to rotate by a fifth driving device.

[0023] See Figure 2In one embodiment of this utility model, a dust removal negative pressure pipe 24 is also fixed on the connecting frame 4. The dust removal negative pressure pipe 24 is connected to a negative pressure pump. The dust removal negative pressure pipe 24 is located behind the dust removal cover 21 and can suck up the waste debris on the battery pack.

[0024] See Figure 3-4 In one embodiment of this utility model, the brush 22 is disposed around the bottom of the dust cover 21.

[0025] In a preferred embodiment of this utility model, the roller brush 23 is made of nylon 66 and silicon carbide. Using this material will not scratch the module surface, and the roller brush is not prone to shedding and is non-conductive.

[0026] In another preferred embodiment of this utility model, the roller brush 23 is made of aluminum oxide, and its performance is the same as in the previous embodiment.

[0027] See Figure 2 In one embodiment of this utility model, the first driving device is a slide cylinder 5. The moving end of the slide cylinder 5 is fixedly connected to the connecting frame 4, which can drive the connecting frame 4 to move up and down, thereby adjusting and driving the brush 22, the roller brush 23 and the dust removal negative pressure pipe 24 to press down on the product surface for dust removal.

[0028] In one embodiment of this utility model, the second driving device is a motor, and the output end of the motor is fixedly connected to the roller brush 23.

[0029] During operation, when the battery pack enters the working range of the dust removal mechanism, the moving end of the slide cylinder descends, causing the connecting frame 4 and the dust removal cover 21, brush 22 and roller brush 23 fixed on the connecting frame 4 to press down on the product surface. The brush 22 contacts the battery pack first, and the roller brush 23 cleans the surface of the battery pack through the motor drive. At the same time, the dust removal negative pressure pipe 24 draws a vacuum.

[0030] The above description is only for other related technical fields of this utility model, and they are all included within the scope of patent protection of this utility model.
