Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a coating machine for a nickel-hydrogen battery cell. Background Art

[0002] Nickel-metal hydride batteries are rechargeable batteries that require coating of the outer wall of the battery cell during the production process. The coating process allows the active material to be evenly distributed on the electrode surface, increasing the conductivity and mechanical strength of the electrode, thereby improving the performance of the battery.

[0003] After searching, the patent number CN210159877U discloses a coating machine for processing lithium-ion battery cells. The coating machine drives two active rollers to rotate through a motor, and the two active rollers drive the second conveyor belt to move, and the second conveyor belt drives the metal foil to move. At the same time, the active roller drives two driven rollers to rotate, and the two driven rollers drive the first conveyor belt to move, and the first conveyor drives the coating to move. The coating at the top absorbs the slurry and moves to the bottom to coat the metal foil.

[0004] When the above-mentioned coating machine coats the battery cell, due to the single-sided coating setting, it can only coat one side of the battery cell, which reduces the comprehensiveness of the coating. At the same time, when the battery cell is transmitted through the conveyor belt, it rubs against the coating, which easily causes the battery cell to roll on the conveyor belt and cannot move.

[0027] The utility model embodiment discloses a nickel-hydrogen battery core coating machine.

[0028] The utility model provides Figure 1-4 The nickel-hydrogen battery cell coating machine shown includes a support frame 1 and a driving rod 2 rotatably arranged at both ends of the support frame 1, a coating rod 3 is fixedly sleeved on the rod wall of the driving rod 2, a material box 4 is fixedly arranged at the lower end of the outer side of the support frame 1, two horizontal tubes 5 are fixedly penetrated at the upper end of the side wall of the support frame 1, a vertical tube 6 is commonly connected between the two horizontal tubes 5 and the material box 4, a material pump 7 is fixedly sleeved on the lower end of the outer side of the vertical tube 6, and a plurality of nozzles 8 arranged at intervals are connected on the adjacent sides of the two horizontal tubes 5, a first circular gear 9 is fixedly sleeved on the rod walls of the two driving rods 2, and the two first circular gears 9 are meshed, a motor 10 is fixedly arranged on the outer side of the support frame 1, and the output end of the motor 10 passes through the support frame 1 and is fixedly connected to the driving rod 2, and the motor 10 is a reduction motor.

[0029] Before coating, the coating slurry is filled into the material box 4, and then the motor 10 is started, so that the two driving rods 2 drive the two coating rods 3 to rotate in opposite directions under the meshing of the two first circular gears 9. At this time, the material pump 7 is started to transport the slurry inside the material box 4 to the vertical pipe 6 and then into the horizontal pipe 5. Through the setting of multiple nozzles 8, the slurry can be sprayed onto the surface of the coating rod 3. When the surface of the coating rod 3 is evenly covered with the slurry, the battery cell is transported between the two coating rods 3. Through contact with the two coating rods 3, the outside of the battery cell can be fully coated, thereby improving the coating effect.

[0030] In order to stably transport the battery cells between the coating rods 3 during coating, Figure 2-4 As shown, a conveying coating mechanism for driving the battery cell to move is provided between the two coating rods 3, and the conveying coating mechanism includes a plurality of symmetrically arranged rotating rods 11, and the rod wall of the rotating rod 11 passes through the support frame 1 and is provided with a transmission mechanism, and the transmission mechanism includes two symmetrically arranged pulleys 16, and the two pulleys 16 are respectively fixedly sleeved with the rotating rod 11 and the driving rod 2, and a belt 17 is provided for transmission between the two pulleys 16;

[0031] The rotating rod 11 is rotatably penetrated through the side wall of the support frame 1, and a sprocket 12 is fixedly sleeved on the rod wall of the rotating rod 11. A chain 13 is provided on the common transmission sleeve outside the multiple sprockets 12 on the same side, and a placement ring 15 is fixedly provided on the adjacent side of the two chains 13 through a connecting rod 14. A strip hole is provided inside the placement ring 15, and a bidirectional screw rod 18 is rotatably penetrated in the strip hole. Clamps 19 are threadedly sleeved on both ends of the rod wall of the bidirectional screw rod 18, and the clamps 19 pass through the strip hole and are located in the placement ring 15. A sliding hole for sliding with the clamps 19 is provided on the top of the strip hole. One end of the bidirectional screw rod 18 passes through the placement ring 15 and is fixedly sleeved with a second circular gear 20. A rack 21 is fixedly provided at the lower end of the inner wall of the support frame 1, and the second circular gear 20 and the rack 21 are matched.

[0032] When the motor 10 is working, the driving rod 2 rotates, and under the transmission of the two pulleys 16 and the belt 17, the rotating rod 4 rotates synchronously. At this time, through the transmission of multiple sprockets 12 and chains 13, and under the connection of the connecting rod 14, multiple placement rings 15 can be transmitted, so that when the placement ring 15 enters between the two coating rods 3, the battery cell is placed in the placement ring 15, and the bidirectional screw rod 18 is rotated so that the two clamps 19 clamp the battery cell. At this time, both sides of the battery cell pass through the placement ring 15, so that during the transmission process of the placement ring 15, the coating rod 3 can contact the surface of the battery cell and obtain stable coating. After the coating of the battery cell is completed, the placement ring 15 is transmitted to the bottom. At this time, the second circular gear 20 is engaged with the rack 12, so that the bidirectional screw rod 18 is reversed. At this time, the two clamps 19 are away from each other, so that the battery cell can be dropped and disassembled by its own gravity.

[0033] In order to avoid the waste of excess slurry falling to the ground during coating, Figure 1-2 As shown, a material receiving box 22 is fixedly provided at the lower end of the inner wall of the support frame 1 , and a material guiding pipe 23 is provided between the material receiving box 22 and the material box 4 , and the material guiding pipe 23 is fixedly provided inside the support frame 1 .

[0034] During the coating process, excess slurry can fall into the material receiving box 22 and be transported by the material guide pipe 23 to enter the material box 4 again for utilization, thereby avoiding the waste of slurry as much as possible.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
