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

[0026] The mechanism for arranging the cap 103 on the liquid filling machine includes a clamping jaw mounting seat 10 and a shaping bracket 20, the shaping bracket 20 is mounted on the top of the clamping jaw mounting seat 10, and the front end bottom of the clamping jaw mounting seat 10 is connected with a clamping plate 40 for clamping the battery shell 101 and a magnetic mechanism 50 for magnetically attracting the battery shell 101, and the magnetic mechanism 50 cooperates with the clamping plate 40;

[0027] The shaping bracket 20 is connected to a cylinder mounting plate 30 , and the cylinder mounting plate 30 is connected to an upper and lower cylinder 31 that drives the shaping magnet seat 33 to move up and down. The upper and lower cylinders 31 are connected to the shaping magnet seat 33 through a first push-pull rod 32 , and the shaping magnet seat 33 is located above the clamping plate 40 .

[0028] In the mechanism for arranging the caps 103 on the injection machine provided above, the cylinder mounting plate 30 drives the shaping magnet seat 33 through the upper and lower cylinders 31 to absorb the caps 103 and move them upward so that multiple caps 103 are uniformly arranged in the vertical and horizontal directions. The clamping claw mounting seat 10 uses the clamping plate 40 to fit and position the battery shell 101, and then uses the magnetic mechanism 50 to magnetically absorb the battery shell 101, which can effectively reduce the interference of the caps 103 on the injection process. The structural design is simple and reasonable, can effectively arrange the caps 103 with high arranging efficiency, and thus helps to improve the production yield of cylindrical batteries, and solves the problem of poor arranging effect and low arranging efficiency of the caps 103.

[0029] In this embodiment, a plurality of upper and lower magnets 34 for magnetically attracting the cap 103 are provided on the shaping magnet seat 33. The plurality of upper and lower magnets 34 are arranged in sequence and spaced apart along the length direction of the shaping magnet seat 33, and the upper and lower magnets 34 are embedded in the bottom of the shaping magnet seat 33.

[0030] The shaping magnet seat 33 magnetically attracts the cap 103 through the upper and lower magnets 34, and then controls the sorting effect of the cap 103 by moving the upper and lower magnets 34 through the shaping magnet seat 33, so that the cap 103 effectively reduces the interference with the injection process.

[0031] In this embodiment, the clamping plate 40 has a plurality of inwardly recessed clamping grooves 42 for clamping the battery shell 101. The plurality of clamping grooves 42 are arranged in sequence and spaced apart along the length direction of the clamping plate 40. The clamping grooves 42 are arranged opposite to the upper and lower magnets 34. A clamping bar 43 for clamping the annular groove 105 is convexly provided in the clamping groove 42, and the clamping bar 43 is arranged in an arc shape.

[0032] The clamping plate 40 fits the battery shell 101 through the clamping groove 42, and the clamping groove 42 uses the clamping bar 43 to clamp the annular groove 105 of the battery shell 101. The clamping jaw mounting seat 10 magnetically attracts the battery shell 101 through the magnetic mechanism 50, so that the battery shell 101 can be positioned and fitted in the clamping groove 42, and the arc shape of the clamping bar 43 can be used to clamp annular grooves 105 of different sizes.

[0033] In this embodiment, the front end of the clamping plate 40 has a positioning strip 41 protruding outward, the positioning strip 41 is exposed outside the front end of the clamping jaw mounting seat 10, the top end surface of the positioning strip 41 and the front end surface of the clamping plate 40 form a step, and the clamping groove 42 is located on the front end of the positioning strip 41. In this way, when the clamping groove 42 is attached to the battery shell 101, the front end of the clamping plate 40 will not hinder the battery shell 101.

[0034] In this embodiment, the magnetic mechanism 50 includes a magnet connecting plate 51 and a horizontal cylinder 52 that drives the magnet connecting plate 51 to move forward and backward. The horizontal cylinder 52 is installed on the clamp mounting base 10. The horizontal cylinder 52 is connected to the magnet connecting plate 51 through a second push-pull rod 53. The magnet connecting plate 51 is provided with a horizontal magnet 54 corresponding to the clamping groove 42. Multiple horizontal magnets 54 are arranged in sequence along the length direction of the magnet connecting plate 51.

[0035] The second push-pull rod 53 of the horizontal cylinder 52 drives the magnet connecting plate 51 to move forward and backward, so that the magnet connecting plate 51 pushes and pulls the horizontal magnet 54 to magnetically attract or demagnetize the battery shell 101.

[0036] In this embodiment, the clamping plate 40 is provided with a guide hole 44 for the horizontal magnet 54 to penetrate and insert, and the guide hole 44 is connected to the clamping groove 42. In this way, the clamping plate 40 can directional move the horizontal magnet 54 through the guide hole 44, so that the horizontal magnet 54 can position the magnetic battery shell 101, thereby increasing the control of the magnetic attraction position of the battery shell 101.

[0037] The magnet connecting plate 51 is located between the driving cylinder and the clamping plate 40, and the magnet connecting plate 51 is movably abutted against the rear end of the clamping plate 40. In this way, when the magnet connecting plate 51 controls the horizontal magnet 54 to move backward, the battery shell 101 will not move with the horizontal magnet 54 when it is obstructed by the clamping plate 40, so as to realize the demagnetization of the magnet connecting plate 51.

[0038] The guide hole 44 penetrates the clamping plate 40 along a direction from the magnet connecting plate 51 to the clamping plate 40 , and the guide hole 44 is located below the clamping bar 43 .

[0039] In this embodiment, the cylinder mounting plate 30 is connected to the cap baffle 36 through the mounting vertical plate 35. The cap baffle 36 is located above the clamping plate 40. The cap baffle 36 has a shaping groove 37 for the shaping magnet seat 33 to be inserted through. The shaping groove 37 is extended along the length direction of the cap baffle 36.

[0040] The shaping groove 37 in the cap baffle 36 is used to position and move the shaping magnet seat 33. When the shaping magnet seat 33 drives the upper and lower magnets 34 to move upward, the upper part of the cap 103 will enter the cap baffle 36. The cap baffle 36 uses the shaping groove 37 to orient and limit the cap 103, so that the cap 103 can be better arranged.

[0041] In this embodiment, the shaping groove 37 runs from top to bottom along the top of the cap baffle 36 to the bottom of the cap baffle 36, and a plurality of anti-sway guide shafts 38 for limiting the swing of the shaping magnet seat 33 are movably connected on the top of the cap baffle 36, and the plurality of anti-sway guide shafts 38 are arranged in sequence along the length direction of the cap baffle 36.

[0042] The cap baffle 36 assists in guiding and limiting the shaping magnet seat 33 moving up and down through the anti-sway guide shaft 38, thereby preventing the shaping magnet seat 33 from swaying sideways during the movement.

[0043] In this embodiment, the clamp mounting base 10 is connected with a front and rear cylinder 11 that drives the shaping bracket 20 to slide forward and backward. The front and rear cylinders 11 are connected to the shaping bracket 20 through a third push-pull rod 12 to enable the cap baffle 36 to push multiple caps 103 to be arranged side by side.

[0044] The front and rear cylinders 11 control the movement of the shaping bracket 20 through the third push-pull rod 12, so that the shaping bracket 20 drives the cap baffle 36 to push the caps 103 to align side by side, which can effectively reduce the interference of the caps 103 on the injection process. The cap 103 sorting device has the characteristics of good sorting effect and high sorting efficiency, which can further help to improve the production yield of cylindrical batteries.

[0045] When the liquid injection manipulator is in the state of clamping the battery shell 101, the magnet connecting plate 51 abuts against the clamping plate 40, and the outer end of the horizontal magnet 54 passes through the guide hole 44 and is exposed in the clamping groove 42, and the battery shell 101 is magnetically attracted;

[0046] When the liquid injection robot is in the process of releasing the battery shell 101 , the magnet connecting plate 51 and the clamping plate 40 are spaced apart, and the horizontal magnet 54 is separated from the battery shell 101 .

[0047] 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.
