[0025] Reference Figure 1-4 As shown, it is a preferred embodiment provided by the utility model.

[0026] The invention discloses an injection robot suitable for clamping battery shells 101 of different sizes, comprising a clamping jaw mounting seat 10 and a clamping plate 20 for clamping the battery shell 101, wherein the clamping plate 20 is connected to the front end bottom of the clamping jaw mounting seat 10, and the clamping plate 20 has a plurality of clamping grooves 22 which are recessed inwards and used for clamping the battery shell 101, wherein the plurality of clamping grooves 22 are arranged in sequence and spaced apart along the length direction of the clamping plate 20, and a clamping bar 23 for clamping the annular groove 105 is convexly provided in the clamping groove 22, and the clamping bar 23 is arranged in an arc shape, and the clamping jaw mounting seat 10 is connected to a magnetic mechanism 30 for magnetically attracting the battery shell 101.

[0027] The above-mentioned liquid injection robot is suitable for clamping battery shells 101 of different sizes. The clamping plate 20 fits the battery shell 101 through the clamping groove 22. The clamping groove 22 uses the clamping bar 23 to clamp the annular groove 105 of the battery shell 101. The clamping jaw mounting seat 10 magnetically absorbs the battery shell 101 through the magnetic mechanism 30, so that the battery shell 101 can be positioned and fitted in the clamping groove 22. The structural design is simple, and the arc shape of the clamping bar 23 can be used to clamp annular grooves 105 of different sizes, which solves the problem that the liquid injection robot has unsatisfactory effect when clamping battery shells 101 of different sizes.

[0028] In this embodiment, the clamping groove 22 is arranged in an arc shape, and the clamping bar 23 is arranged to extend in the horizontal direction of the clamping groove 22. The clamping groove 22 is also arranged in an arc shape, so that the clamping groove 22 can be more closely contacted when clamping the battery shell 101, thereby improving the positioning of the battery shell 101.

[0029] In this embodiment, the front end of the clamping plate 20 has a positioning strip 21 protruding outward, the positioning strip 21 is exposed outside the front end of the clamping jaw mounting seat 10, and the clamping groove 22 is located on the front end of the positioning strip 21. In this way, when the clamping groove 22 is attached to the battery shell 101, the front end of the clamping plate 20 will not hinder the battery shell 101.

[0030] In this embodiment, the magnetic mechanism 30 includes a magnet connecting plate 31 and a driving cylinder 40 that drives the magnet connecting plate 31 to move forward and backward. The driving cylinder 40 is installed on the clamp mounting base 10. The driving cylinder 40 is connected to the magnet connecting plate 31 through a telescopic push-pull rod 41. The magnet connecting plate 31 is provided with a magnet 32 ​​corresponding to the clamping groove 22, and multiple magnets 32 are arranged in sequence along the length direction of the magnet connecting plate 31.

[0031] The magnet connecting plate 31 is driven to move forward and backward by driving the telescopic push-pull rod 41 of the air cylinder 40 , so that the magnet connecting plate 31 pushes and pulls the magnet 32 ​​to magnetically attract or demagnetize the battery shell 101 .

[0032] In this embodiment, the magnet connecting plate 31 is located between the driving cylinder 40 and the clamping plate 20, and the magnet connecting plate 31 is movably abutted against the rear end of the clamping plate 20. In this way, when the magnet connecting plate 31 controls the magnet 32 ​​to move backward, the battery shell 101 will not move with the magnet 32 ​​when it is blocked by the clamping plate 20, so as to achieve the demagnetization of the magnet connecting plate 31.

[0033] In this embodiment, the clamping plate 20 is provided with a guide hole 24 for the magnet 32 ​​to penetrate and insert, and the guide hole 24 is connected to the clamping groove 22. In this way, the clamping plate 20 can move the magnet 32 ​​in a directional manner through the guide hole 24, so that the magnet 32 ​​can position the magnetically attracted battery shell 101, thereby increasing the control of the magnetically attracted position of the battery shell 101.

[0034] The guide hole 24 penetrates the clamping plate 20 along a direction from the magnet connecting plate 31 to the clamping plate 20 , and the guide hole 24 is located below the clamping bar 23 .

[0035] In this embodiment, the magnet connecting plate 31 has a plurality of inwardly recessed fixing grooves 33, the inner ends of the magnets 32 abut against the fixing grooves 33, and the outer ends of the magnets 32 are exposed outside the magnet connecting plate 31. In this way, the installation and positioning of the magnets 32 can be increased.

[0036] In this embodiment, the inner end of the magnet 32 ​​is movably connected to the magnet connecting plate 31 through a connector. In this way, the magnet 32 ​​can be removed or installed from the magnet connecting plate 31 through the connector, which is convenient for replacing the magnet 32.

[0037] When the liquid injection manipulator is in the state of clamping the battery shell 101, the magnet connecting plate 31 abuts against the clamping plate 20, and the outer end of the magnet 32 ​​passes through the guide hole 24 and is exposed in the clamping groove 22, and the battery shell 101 is magnetically attracted;

[0038] When the liquid injection robot is in the process of releasing the battery shell 101 , the magnet connecting plate 31 is spaced apart from the clamping plate 20 , and the magnet 32 ​​is separated from the battery shell 101 .

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
