[0027] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0028] like Figures 1 to 5 As shown, this embodiment provides a casting filter suction device 1, comprising: a telescopic device 101, a magnet 102 is fixedly provided at the telescopic end of the telescopic device 101, an electric signal detection mechanism 103 is provided on the peripheral side of the magnet 102, and the plane where the front end of the electric signal detection mechanism 103 is located is consistent with the plane where the front end of the magnet is located before the telescopic device is retracted. In this embodiment, the electric signal detection mechanism 103 includes an insulating mounting sleeve 1031 and a conductive strip 1033, and two conductive strips 1033 are provided, and the two conductive strips 1033 are respectively fixedly installed on the insulating mounting sleeve 1031, and the plane where the front end of the two conductive strips 1033 is located is consistent with the plane where the front end of the magnet 102 is located before the telescopic device is retracted.

[0029] In the specific implementation process of the above embodiment, the filter 301 adopts a material that can be adsorbed by a magnet, such as an iron filter; the telescopic device 101 can adopt a cylinder. When the filter 301 needs to be placed on the casting hole, the telescopic device is extended so that the plane where the front end of the magnet is located and the plane where the front end of the conductive strip is located are in the same plane. At this time, the magnet absorbs the filter 301 from the filter placement area, and after absorption, it moves to the casting hole and aligns with the casting hole. At this time, the telescopic device contracts, driving the magnet to retract into the insulating mounting sleeve. At this time, the filter is blocked by the end of the insulating mounting sleeve and is forced to separate from the magnet. The separated magnet is placed at the casting hole several times. During this process, the electrical signal detection mechanism can detect in real time whether the end of the magnet has absorbed the filter. Specifically: when the magnet absorbs the filter from the filter placement area, the electrical signal detection mechanism is energized. At this time, the filter is equivalent to the conductor between the two conductive strips, that is, the electrical signal detection mechanism is energized. If the filter is not absorbed, the electrical signal detection mechanism is not energized. In this process, whether the filter is absorbed by the magnet or falls from the magnet can also be detected by whether the electrical signal detection mechanism is energized; when the filter is placed at the casting hole, the filter is separated from the magnet. Since the plane where the front end ends of the two conductive strips are located is consistent with the plane where the front end ends of the magnet are located before the telescopic device contracts, the filter is also separated from the two conductive strips. At this time, the electrical signal detection mechanism is not energized, and this method can be used to determine whether the filter is placed at the casting hole.

[0030] like Figure 3 and Figure 4 As shown, in order to facilitate the fixation of the insulating mounting sleeve, the telescopic end of the cylinder passes through the insulating mounting sleeve, and the bottom end of the insulating mounting sleeve is fixedly connected to the fixed end of the telescopic device. In order to facilitate the installation of the conductive strip, in some embodiments, the insulating mounting sleeve 1031 is symmetrically provided with mounting grooves 1032, and two conductive strips 1033 are respectively fixedly installed in the mounting grooves 1032. In order to improve the insulation of this embodiment, that is, to provide detection accuracy and avoid errors, in some embodiments, the electrical signal detection mechanism also includes an insulating strip 1034, and the insulating strip 1034 is respectively fixedly installed in the mounting grooves 1032, and the two conductive strips 1033 are respectively installed on the insulating strip 1034. In the above embodiment, the two conductive strips of the electrical signal detection mechanism are connected to an external power supply through the wiring terminal 1035.

[0031] like Figures 6 to 9 As shown, this embodiment also provides a battery pack shell grabbing clamp, including: a bracket 2, an external flange 201 is provided in the middle of one side of the bracket 2, a plurality of clamp assemblies 205 are provided on the surrounding side of the bracket 2, the clamp assemblies 205 are arranged toward the clamping surface 202 of the bracket, and the other side of the bracket located on the clamping surface of the bracket is a filter suction surface 203, and the filter suction surface 203 is provided with a plurality of casting filter suction devices 1 described in any one of the above embodiments.

[0032] In this embodiment, if Figure 7 As shown, the casting filter suction device 1 is fixedly connected to the filter suction surface 203 of the bracket 2 through the support column 204. The clamping jaw assembly 205 includes a clamping cylinder 2051, a cylinder fixing seat 2052, a clamping finger 2053 and a support fixing seat 2054. The clamping cylinder 2051 is fixedly connected to the bracket 2 through the cylinder fixing seat 2052, the clamping finger is arranged at the end of the cylinder, and the support fixing seat is fixedly arranged on the bracket, as shown in FIG. Fig. 9 As shown, the side wall of the bracket can be provided with an extension, and the cylinder fixing seat and the support fixing seat can be installed on the extension. The adaption between the clamping fingers and the support fixing seat means that after the clamping fingers clamp the battery pack shell 302, the lower surface of the battery pack shell 302 clamped by the clamping fingers just rests on the support fixing seat, so that the clamping fingers and the support fixing seat can clamp the battery pack shell. The clamping cylinder adopts a clamping cylinder of model JCK40; in this embodiment, the battery pack shell grabbing clamp can effectively grasp the battery pack shell by setting a clamping clamp assembly, thereby facilitating automatic generation and processing; in addition, by setting a casting filter suction device on the other side of the bracket, the filter 301 can be effectively placed in the casting hole before the casting of the battery pack shell, so as to achieve the dual-purpose purpose of the battery pack shell grabbing clamp, effectively saving costs and improving efficiency.

Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described herein, or equivalent structural or equivalent process transformations made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the scope of patent protection of the utility model.
