Description

TECHNICAL FIELD

[0002] In the production process of battery modules, cleaning the battery module box is a crucial step. Traditional methods of cleaning the battery module box rely mainly on manual operation, which is not only inefficient but also difficult to ensure the quality of cleaning. Manual cleaning often has uneven cleaning, difficulty in completely removing stubborn dirt, potential health risks to operators, and other problems. In addition, due to differences in skill levels and work attitudes of different operators, the consistency of cleaning results is poor, which affects subsequent production processes such as gluing and assembly.

[0003] With the rapid development of automation technology, the demand for automated cleaning equipment in the industrial field is increasing.

This single function not only increases equipment costs and occupies space, but also reduces cleaning efficiency. More importantly, single-function cleaning equipment can also lead to a series of product quality problems. For example, if the brush dust removal and plasma cleaning are not performed at the same station, there is a long time difference between them. In the transportation process, dust may fall on the surface of the battery module box again.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] The first aspect of the present application, see Figures 1 to 5The application provides a battery module box cleaning device, which comprises a structure support 1, a brush cleaning assembly, a plasma cleaning assembly, a profile measurement assembly and a negative pressure dust collection assembly.

[0041] Specifically, the profile measurement assembly can adopt a laser profile measuring instrument as a core component, and the working principle of the laser profile measuring instrument is prior art; the laser profile measuring instrument first projects a laser line to the inner wall surface of the battery module box; when the laser line is projected to the measured inner wall surface, it forms a bright line on the inner wall surface; due to the difference in the shape of the inner wall surface, the position of the laser line on the inner wall surface also changes, and these changes are reflected in the image captured by the camera; a triangle is formed among the laser light source, the inner wall surface and the camera lens, and when the laser line is irradiated to the inner wall surface and reflected to the camera, the angle of the reflected light changes according to the height change of the inner wall surface; after the camera captures the changes, the height information of the corresponding position of the inner wall surface can be calculated by calculating the angle and position of the reflected light; then, the measuring instrument calculates the profile information of the inner side of the battery module box according to the known camera parameters, laser line parameters and image processing results.

[0042] Specifically, the plasma cleaning assembly can adopt a plasma generator as a core component, and the working principle of the plasma generator is prior art; the plasma generator generates high-voltage high-frequency energy in the nozzle steel pipe of the spray gun, which is activated and controlled in the glow discharge to generate low-temperature plasma, and the plasma is sprayed to the workpiece surface by compressed air; when the plasma meets the surface of the object to be cleaned, chemical action and physical change are generated, the surface is cleaned and carbonized hydrogen pollutants such as oil, auxiliary additives and the like are removed; according to the material composition, the molecular chain structure of the surface is changed; hydroxyl, carboxyl and other free radicals are established, these radicals have the effect of promoting the adhesion of various coating materials, and the application of adhesion, coating, gluing, painting and printing is optimized.

[0043] In the embodiment, the mechanical arm drives the cleaning device to displace in the battery module box according to a predetermined path through the structure support 1, so as to cover the whole inside of the box; the brush cleaning assembly sweeps the dust on the inner wall of the box during the displacement process; the plasma cleaning assembly performs plasma cleaning during the displacement process; the profile measurement assembly performs three-dimensional scanning during the displacement process; and the negative pressure dust collection assembly removes the dust and impurities on the inner wall of the box during the displacement process.

[0044] The cleaning device integrates multiple functions of cleaning and dust removal, plasma cleaning, profile measurement and negative pressure dust collection. Once cleaning path can realize comprehensive cleaning of the battery module box, reducing the number of required stations in the cleaning process, reducing the cleaning steps, improving the efficiency and reducing the production cost.

[0045] The cleaning device is driven by the mechanical arm to displace in the box according to a predetermined path, ensuring coverage of the entire box interior, further improving the cleaning efficiency. The automatic cleaning method is faster and more thorough than the traditional manual cleaning.

[0046] The plasma cleaning assembly cleans the inside of the box by plasma, removes hydrogen carbonaceous dirt, changes the surface molecular chain structure, establishes free radicals to promote adhesion, improves the surface energy of the box, ensures the gluing effect, and enhances the stability of the battery module in the box.

[0047] The profile measurement assembly scans the inside of the battery module box in real time during the cleaning process and draws a three-dimensional map, providing strong data support for automatic gluing, automatic gluing path planning and automatic gluing of different specifications and models of boxes, improving the intelligent level of production and ensuring the accuracy and consistency of gluing.

[0048] The design of integrating and arranging the brush cleaning assembly and the plasma cleaning assembly in front and back can remove most of the dust and dirt on the surface of the box through box cleaning, providing a relatively clean surface for subsequent plasma cleaning. Plasma cleaning can further remove hydrogen carbonaceous dirt, change the surface molecular chain structure, and establish free radicals to promote adhesion. The double cleaning method can ensure the cleanliness and surface energy of the box surface.

[0049] The design of integrating and arranging the brush cleaning assembly and the plasma cleaning assembly in front and back allows the box to be immediately plasma cleaned after cleaning, minimizing the waiting time difference and avoiding the risk of the box falling again when transferring or switching equipment, ensuring the surface energy of the box.

[0050] Placing the profile measurement assembly after cleaning and dust removal and plasma cleaning can ensure that the inside surface of the box has reached a very high cleanliness when measuring, thereby improving the accuracy and reliability of the measurement.

[0051] In some embodiments, the brush cleaning assembly includes: a mounting shell 2 connected to a structural support 1, provided with a dust suction pipe interface and a cleaning opening 3, the dust suction pipe interface being used to connect a negative pressure dust collection assembly; a brush assembly rotatably arranged inside the mounting shell 2, one side of which extends out of the cleaning opening 3 for lifting or carrying dust.

[0052] Specifically, when the brush cleaning assembly is working, the brush assembly starts to rotate under the action of driving force, the rotating brush contacts the surface of the object, raising or carrying the dust on the surface, at the same time, the negative pressure suction assembly is connected with the mounting shell 2 through the suction pipe interface, generating suction force to timely suck up the raised dust. In this way, the brush cleaning assembly can effectively clean the inside surface of the box.

[0053] In some embodiments, the brush assembly comprises: a driving wheel 4, a fixed wheel 5 and a tensioning wheel 6, which are rotatably arranged inside the mounting shell 2 and are in a triangular distribution; a belt 7, which is sleeved outside the driving wheel 4, the fixed wheel 5 and the tensioning wheel 6; bristles 8, which are arranged at intervals outside the belt 7 and partially protrude from the cleaning port 3; and a brush driving device 9, which is arranged outside the mounting shell 2 and is used to drive the driving wheel 4 to rotate.

[0054] Specifically, when the brush driving device 9 starts to work, it drives the driving wheel 4 to rotate, which drives the belt 7 to move, and the bristles 8 on the belt 7 rub against the surface to be cleaned, thereby effectively raising or carrying away the dust and dirt. The fixed wheel 5 and the tensioning wheel 6 play an important role in stabilizing the movement track of the belt 7 and maintaining the tension of the belt. The triangular distribution of the wheels and the close winding of the belt 7 enhance the stability of the brush assembly during operation, so that the brush assembly can adapt to various shapes and profiles of the surface to be cleaned, improving flexibility.

[0055] In some embodiments, the brush cleaning assembly comprises: a guide rail, which is vertically connected to the structural support 1; a sliding block 10, one side of which is in sliding cooperation with the guide rail and the other side of which is fixed with the mounting shell 2; and a lifting driving device 11, which is connected to the structural support 1 and is used to drive the mounting shell 2 to lift. When the lifting driving device 11 acts on the mounting shell 2, the mounting shell 2 is lifted along the guide rail through the sliding cooperation of the sliding block 10 and the guide rail, so that the height position of the brush assembly changes accordingly. In this way, the distance and contact force between the brush assembly and the surface to be cleaned can be flexibly adjusted according to the actual cleaning needs.

[0056] In some embodiments, the cleaning port 3 is parallel to the bottom side of the belt 7; the mounting shell 2 is provided with two inclined walls, which are respectively parallel to the other two sides of the belt 7; and each inclined wall is provided with a suction pipe interface for connecting the negative pressure suction assembly. This design reduces the space occupation; the suction pipe interface is provided on each inclined wall, so that the suction assembly can timely suck up the raised dust, improving the suction efficiency.

[0057] In some embodiments, the bristles 8 are located between the inclined wall and the belt 7, and a duster rod 20 is installed in the installation housing 2 and located on the movement path of the bristles 8. The duster rod 20 helps the bristles 8 to shake off the dust and dirt attached in time, prevents the bristles 8 from reducing the cleaning effect due to dust accumulation, and facilitates the dust suction assembly to suck up the dust raised in time.

[0058] In some embodiments, the plasma cleaning assembly comprises: a plurality of plasma spray guns 12, each connected to the structural support 1, and the spray port 14 of each plasma spray gun 12 is arranged downward. A plurality of dust suction covers 13 are connected to the spray ports 14 one by one, and the opening is downward to cover the spray port 14; the peripheral side wall of each dust suction cover 13 is provided with a dust suction pipe interface for connecting the negative pressure dust suction assembly. The spray port 14 of the plasma spray gun 12 is arranged downward, and the plasma flow generated thereby can directly reach the surface of the box body, rapidly decompose and remove the dirt and oil on the surface to be cleaned, and achieve high cleaning efficiency. The cooperation of the dust suction cover 13 and the spray port 14 ensures that the waste gas and impurities generated during the cleaning process can be sucked away in time and effectively, and the working environment is kept clean.

[0059] In some embodiments, the triangular plane formed by the power wheel 4, the fixed wheel 5 and the tensioning wheel 6 is perpendicular to the cleaning direction; and the plurality of plasma spray guns 12 are parallel to the triangular plane, so as to maximize the cleaning range.

[0060] In some embodiments, the profile measurement assembly comprises: a 3D line laser profile measurement instrument 15 connected to the structural support 1, and the scanning lens is downward, which is used for three-dimensional scanning of the inside of the box body. The 3D line laser profile measurement instrument 15 adopts laser scanning technology and can measure without contacting the surface of the inside of the box body, and is suitable for profile measurement of the inside of the box body of various types and materials.

[0061] In some embodiments, the negative pressure dust suction assembly comprises: a first dust suction pipe 16 connected to the brush cleaning assembly for sucking out the dust cleaned; a second dust suction pipe 17 connected to the plasma cleaning assembly for sucking out the impurities cleaned by the plasma; a third dust suction pipe 18 connected to the structural support 1 and suspended at one end for sucking the dust at the corner of the battery module box body; and a negative pressure main pipe 19 connected to an external dust suction device and connected to each branch dust suction pipe.

[0062] Specifically, the negative pressure dust suction assembly realizes comprehensive dust suction of the brush cleaning assembly, the plasma cleaning assembly and the corner of the battery module box body through the design of the three branch dust suction pipes, has a compact structure, is easy to install and maintain, and the dust suction pipe and the negative pressure main pipe are convenient to disassemble and replace, thereby reducing the maintenance cost.
