BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The above and other features of the present invention will become apparent with reference to the accompanying drawings, in which:

[0023] Figure 1 An embodiment of the separation device according to the present application is schematically shown. DETAILED DESCRIPTION

[0024] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0025] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to their different positions and different usage states. Therefore, these or other directional terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", "third", etc. or similar expressions are only used for description and distinction purposes, and cannot be understood as indicating or implying the relative importance of the corresponding components.

[0026] refer to Figure 1 , which schematically shows an embodiment of the separation device according to the present application, the separation device 100 is used to disassemble the power battery. Specifically, in a module-free power battery pack using CTP technology, it is used to cut the adhesive structure between the module and the battery pack frame and separate the two, so as to subsequently recycle and reuse the battery cells in the module. The separation device 100 includes a cutting tool 110, a dust hood 120, a negative pressure dust collection assembly 130, and a drive assembly 140. The cutting tool 110 is driven by the drive assembly 140 to cut into the adhesive structure. Here, the cutting tool can be a saw blade, or a grinding wheel, or other cutting tools.

[0027] Here, the dust hood 120 is in a semi-hood shape, which covers the cutting tool externally when the cutting tool is ready to cut or when the cutting tool is cutting, so as to collect the chips generated during the cutting process. A dust collection outlet is also provided on the dust hood 120, which is communicated with the inlet of the first filter device 131 of the negative pressure dust collection assembly 130 through a dust collection pipe 150. The outlet of the first filter device 131 is communicated with the air inlet of the negative pressure fan 132 of the negative pressure dust collection assembly 130 through a dust collection pipe 160, wherein the negative pressure fan is driven by the above-mentioned drive assembly 140. Here, the dust collection pipes 150 and 160 can be hoses. The dust hood can have a reduced size at the dust collection outlet, specifically, the dust hood gradually decreases in size along the direction toward the dust collection outlet to promote the formation of negative pressure thereat.

[0028] Specifically, in Figure 1In the embodiment shown in , the cutting tool 110 cuts the adhesive structure under the driving action of the driving assembly 140, and the chips generated in the cutting process are sucked into the first filtering device 131 by the negative pressure generated by the negative pressure fan 132, and the filtered chips are discharged through the exhaust port of the negative pressure fan 132. Here, the generated chips are promptly led away and filtered by the negative pressure, thereby avoiding the pungent smell of the adhesive structure and the chips from polluting the working environment and thus providing a more friendly working environment.

[0029] The first filter device 131 can be a separation filter integrated machine, in which most of the chips, especially the chips with larger particles, are collected. Specifically, the first filter device 131 is also provided with a dust bag, which is detachably fixed to the body of the first filter device 131, for example, by a buckle or a snap connection. In this way, the chips in the dust bag can be cleaned in time and the dust bag can be replaced and cleaned.

[0030] In addition to the first filter device 131, the negative pressure dust collection assembly 130 also has a second filter device 133, which is arranged at the exhaust port of the negative pressure fan 132 so as to perform a secondary filtration on the chips before they are discharged into the surrounding environment. Here, the second filter device 133 can be configured in a simple manner as a filter screen, which is fixed to the exhaust duct of the negative pressure fan. In addition, the mesh size of the filter screen as the second filter device is smaller than the mesh size in the first filter device and can be set according to the working environment quality requirements.

[0031] In some embodiments, the drive assembly 140 includes a dual-axis motor 141, in particular a dual-axis asynchronous motor. One of the output shafts (i.e., the first output shaft) of the dual-axis motor 141 is coupled to the cutting tool 110 for driving the cutting tool to rotate and thereby cutting the adhesive structure. Optionally, there is a transmission mechanism, such as a belt transmission mechanism 142, between the first output shaft and the cutting tool 110. As shown in the accompanying drawings, the shaft of the driving pulley is fixedly connected to the first output shaft, and the shaft of the driven pulley is fixedly connected to the shaft of the cutting tool 110. In addition, another output shaft (i.e., the second output shaft) of the dual-axis motor 141 is coupled to the negative pressure fan 132 for driving the blades of the negative pressure fan to rotate and thereby generate negative pressure therein. Here, by providing a dual-axis motor, a more compact space design scheme is provided.

[0032] In some embodiments, the separation device further comprises an adjustment assembly (not shown in the drawings), on which at least a cutting tool 110 is fixedly connected, and the adjustment assembly is used to adjust the cutting tool 110 to align with the adhesive structure of the waste battery to be cut. The adjustment assembly comprises a horizontal movement mechanism and a vertical movement mechanism, wherein the horizontal movement mechanism is used to drive the cutting tool 110 to move in a horizontal plane, and the vertical movement mechanism is used to drive the cutting tool 110 to move along a vertical direction. By providing such a three-dimensional adjustment assembly, the cutting tool can be aligned with the adhesive structure and thus non-destructive cutting can be achieved.

[0033] Considering the thickness of the cutting tool, such as the thickness of the saw blade and the thickness of the adhesive structure, it is feasible to move the cutting tool 110 to align with the battery pack frame through the three-dimensional adjustment assembly. In this way, cutting into the battery cells in the module is avoided as much as possible, thereby improving the recycling rate of waste power batteries.

[0034] In some embodiments, the horizontal moving mechanism or the vertical moving mechanism or both can be in the form of a slide rail slider, wherein the slider can slide on the slide rail by means of a hydraulic cylinder or a motor, thereby driving the cutting tool 110 to move. The hydraulic cylinder, especially the motor, can achieve high-precision motion control, thereby achieving alignment accuracy between the cutting tool and the battery pack frame.

[0035] Exemplarily, the horizontal movement mechanism can include two slide rails intersecting each other and extending in the horizontal plane, respectively, and a slider is slidably arranged on each slide rail. By controlling the movement of the two sliders, the cutting tool can be placed at any position in the horizontal plane.

[0036] Here, illustratively, it is also feasible that the adjustment component is a so-called three-dimensional motion platform (i.e., an X / Y / Z motion platform), on which the cutting tool 110, the dust hood 120, the negative pressure dust collection component 130, and the drive component 140 are all arranged and moved by means of the three-dimensional motion platform. In this case, the dust hood 120 can be arranged above the cutting tool so that the cutting tool cuts downward into the adhesive structure, which is conducive to the arrangement of the battery conveying device below.

[0037] In some embodiments, the separation device further includes an alignment detection device, wherein the controller of the separation device can determine whether the cutting tool has been aligned with the adhesive structure or the battery pack frame based on the position information of the cutting tool relative to the battery pack frame to be separated obtained by the alignment detection device. Specifically, the alignment detection device can be arranged at the battery supporting device below the cutting tool 110, wherein the battery supporting device can be a supporting plate for supporting the power battery to be disassembled. The cutting operation is started only after the controller of the separation device determines that the cutting tool has been aligned with the battery pack frame. Exemplarily, when the cutting tool is not aligned with the battery pack frame, the controller can control the existing warning device in the workshop to send a warning signal so that the staff can intervene in time.

[0038] In this regard, in some embodiments, the alignment detection device can be a visual detection device and include a camera, and image data collected by the camera is transmitted to a controller of the separation device and alignment recognition is performed based thereon.

[0039] Of course, it is also feasible that the alignment detection device can also be a laser sensor, which can determine whether the cutting tool and the battery pack frame to be separated are aligned based on the sensor signal collected by the laser sensor about the position of the cutting tool relative to the battery pack frame to be separated.

[0040] In summary, according to the separation device of the present application, by providing a dust hood and a negative pressure dust collection component, the chips generated by the cutting process can be sucked away in time and a more friendly working environment can be provided. In some embodiments of the present application, the quality of the working environment can be further improved by providing a two-stage filtering device. In some embodiments of the present application, by providing a three-dimensional adjustment component to accurately adjust the position of the cutting tool relative to the battery pack frame, non-destructive cutting of the module can be ensured and the recycling rate of waste batteries can be improved. In some embodiments of the present application, by providing an alignment detection device, non-destructive cutting of the module is further ensured.

[0041] It should be understood that all the above preferred embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present invention should be within the legal protection scope of the present invention.
