Battery pole pieces can determine the properties and performance of the battery and are one of the important elements for measuring the quality of the battery.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-6 The utility model provides a technical solution: a sodium ion battery pole piece grinder with a clamping function, comprising: a mounting plate 1, a first motor 2, a second motor 3, a mounting frame 4, a mounting frame 5, a first electric telescopic rod 6, a connecting block 7, a hinged rod 8, a clamping block 9, a second electric telescopic rod 10, a connecting box 11, a first transmission rod 12, a second transmission rod 13, a conical wheel 14, a threaded rod 15, a sleeve 16, a support plate 17, a grinding mechanism 18, a first screw rod 1801, a first connecting block 1802, a limiting rod 1803, a grinding roller 1804, a sliding frame 1805, an elastic telescopic rod 1806, a second screw rod 19, a second connecting block 20, a rack 21 and a gear 22.

[0032] When using the sodium ion battery pole piece grinding machine with clamping function, first Figure 1 and Figure 2 As shown, the mounting frame 5 is mounted on the right side of the left part of the mounting plate 1, the clamping block 9 passes through the right end of the mounting frame 5, and the clamping block 9 and the mounting frame 5 form a sliding structure, the front and rear sides of the left end of the clamping block 9 are rotatably connected to the hinge rod 8, the left end of the hinge rod 8 is rotatably connected to the connecting block 7, the extension rod end of the first electric telescopic rod 6 is fixed to the connecting block 7, and the first electric telescopic rod 6 is fixedly connected to the side wall of the mounting frame 5;

[0033] Put the battery pole piece between the two clamping blocks 9, open the first electric telescopic rod 6 to retract the end of the extension rod, and pull the hinged rod 8 to flip when the first electric telescopic rod 6 drives the connecting block 7 to move left. The hinged rod 8 pulls the clamping block 9 and the mounting frame 5 to slide. The two clamping blocks 9 move toward each other to clamp the battery pole piece. The non-slip rubber pads on the clamping blocks 9 increase friction and prevent damage to the battery pole piece. This clamping method can cope with battery pole pieces of different thicknesses and improve the practicality of the device.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a connection box 11 is fixedly installed on the front side of the lower part of the mounting frame 4, and a pulley is fixedly installed on the lower end of the connection box 11. The connection box 11 and the mounting frame 4 are both moved forward and backward above the mounting plate 1 through the second electric telescopic rod 10, and the rear end of the second electric telescopic rod 10 is fixedly connected to the mounting plate 1. The front end of the first transmission rod 12 passes through the connection box 11, and the first transmission rod 12 is rotatably connected to the inside of the connection box 11, and the first transmission rod 12 is meshed with the second transmission rod 13 for transmission, and the outer side of the second transmission rod 13 is meshed with the conical wheel 14 for transmission, and the conical wheel 14 is fixedly sleeved on the outer side of the lower end of the threaded rod 15, and the sleeve 16 is sleeved on the outer side of the threaded rod 15 and forms a rotating structure with the threaded rod 15, and the support plate 17 is fixedly installed on the upper end of the sleeve 16, and the support plate 17 is slidably connected to the inner side of the connection box 11;

[0035] The first transmission rod 12 is rotated to rotate the second transmission rod 13. When the second transmission rod 13 rotates, it meshes with the conical wheel 14. The conical wheel 14 drives the threaded rod 15 to rotate inside the connection box 11, so that the threaded rod 15 drives the sleeve 16 and the support plate 17 to move upward synchronously. The support plate 17 gradually slides out of the grinding mechanism 18. When the upper surface of the support plate 17 is attached to the lower surface of the battery electrode, the first transmission rod 12 is stopped from rotating. Because the self-locking function of the threaded rod 15 keeps the position of the support plate 17 unchanged, the height of the support plate 17 is adjustable, which is convenient for supporting battery electrodes of different heights and ensuring uniform force during grinding;

[0036] The grinding mechanism 18 is installed on the inner side of the upper part of the mounting frame 4, the right end of the first screw rod 1801 is fixedly connected to the output end of the first motor 2, the first connecting block 1802 is rotatably connected to the outer side of the first screw rod 1801, the lower end of the limit rod 1803 is fixedly connected to the first connecting block 1802, and the front end of the grinding roller 1804 is slidably connected to the outer side of the limit rod 1803, the outer side of the grinding roller 1804 is sleeved with a sliding frame 1805, and the sliding frame 1805 is slidably connected to the grooves opened on the front and rear sides of the upper part of the mounting frame 4, the upper side wall of the sliding frame 1805 is fixedly installed with an elastic telescopic rod 1806, and the lower end of the elastic telescopic rod 1806 is fixedly installed with a block with a lower arc-shaped structure;

[0037] Because the elastic force of the elastic telescopic rod 1806 pushes the grinding roller 1804 to always remain in contact with the upper surface of the battery electrode, the first motor 2 is turned on to rotate the first screw rod 1801, and the first screw rod 1801 drives the first connecting block 1802 to move back and forth left and right. The grinding roller 1804 is driven by the limit rod 1803 to move left and right on the battery electrode. The rotation of the grinding roller 1804 grinds away the foam nickel on the battery electrode. At this time, the sliding frame 1805 slides in the groove on the inner side of the mounting frame 4 to ensure the stability of the grinding process. When the single-sided grinding is completed, the second electric telescopic rod 10 starts to pull the mounting frame 4 and the connecting box 11 backward, and the right part of the battery electrode is in a suspended state.

[0038] like Figure 1 , Figure 2 and Figure 6 As shown, the front end of the second screw rod 19 is fixedly connected to the output end of the second motor 3, the second connecting block 20 is rotatably connected to the second screw rod 19, and the rack 21 is fixed to the upper end of the second connecting block 20 and moves forward and backward through the second connecting block 20, the rack 21 is meshed with the gear 22 for transmission, the left end of the gear 22 is rotatably connected to the mounting plate 1, and the right end of the gear 22 is fixedly installed with the mounting frame 5, the second motor 3 is started to control the second screw rod 19 to rotate, so that 29 drives the rack 21 to move backward, the gear 22 is meshed with the rack 21 to rotate and control the mounting frame 5 and the battery electrode to flip 180 degrees, then the extension rod of the second electric telescopic rod 10 is extended to restore the position of the support plate 17 and the grinding roller 1804, and the battery electrode on the other side is started to be polished, and the automatic flipping method is more flexible and saves working time.
