Description

Technical Field

[0001] The invention relates to the technical field of viscometers, in particular to a lithium battery slurry viscosity testing device. Background Art

[0002] Lithium battery slurry is one of the key materials in the manufacturing process of lithium-ion batteries. It is mainly composed of solid particles, liquid solvents and additives. With the continuous development of lithium battery technology, the requirements for the viscosity of lithium battery slurry are getting higher and higher. When modern lithium battery manufacturers produce lithium battery slurry, most of them will sample the lithium battery slurry and use a viscometer to test the viscosity of the sample.

[0003] As in the prior art, the patent with the patent authorization announcement number CN214539103U discloses a viscometer, which includes a viscometer body, a measuring head and a support frame, the support frame includes a base and a support rod, the support rod is fixed to the upper end of the base, a lifting mechanism is arranged on the support rod, the lifting mechanism includes a mounting seat, a first rack, a first gear and a first adjusting knob, a mounting rod is arranged on the viscometer body, the mounting rod is fixed to the mounting seat, the mounting seat is connected to the support rod, the first rack is arranged along the length direction of the support rod, the first gear is meshed with the first rack, the first adjusting knob is fixed to the first gear, and the first adjusting knob drives the first gear to reciprocate on the first rack, and the first adjusting knob is rotatably connected to the mounting seat. This type of viscometer has the effect of conveniently adjusting the height of the viscometer body and saving manpower.

[0004] Although the viscometer in the above patent has the effect of conveniently adjusting the height of the viscometer body and saving manpower, it still has certain defects; since the rotor of the viscometer is connected to the rotor joint through a threaded connection, it is necessary to ensure that the threads of the rotor and the rotor joint are aligned during installation, and rotate the rotor until it is firmly fixed on the rotor joint, and it is necessary to keep it stable during the rotation process to avoid excessive force causing damage to the rotor joint. The rotor and rotor joint of the viscometer are small in size. After the operator grasps and fixes the rotor joint with one hand, the rotor joint will be blocked by the fingers, making it difficult to see the threaded holes on the rotor joint. The operator can only align the top of the rotor with the rotor joint based on experience, and rely on feeling to thread the rotor and the rotor joint. This installation method is very dependent on the experience of the operator, which makes it difficult for novices to install the rotor. Summary of the invention

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] See also Figures 1 to 11 A lithium battery slurry viscosity testing device comprises a lifting frame 1, a main machine 2 is installed on the upper end of the lifting frame 1, a rotating shaft cup 3 is connected to the bottom of the main machine 2, a joint 4 is connected to the bottom of the rotating shaft cup 3, a mounting sleeve 6 is connected to the outer side of the rotating shaft cup 3, upper protective legs 7 are fixedly connected to both sides of the mounting sleeve 6, a transmission assembly is connected to the middle position of each upper protective leg 7, a lower protective leg 12 is provided below the upper protective leg 7, a pushing assembly matching the transmission assembly is fixedly connected to both sides of the lower protective leg 12, a rotor 5 threadedly connected thereto is provided below the joint 4, the lower protective leg 12 is an integral part composed of two symmetrical L-shaped plates, a slot 24 matching the rotor 5 is provided at the connection of the two lower L-shaped plates, an auxiliary protective leg 28 is connected to the lower end of the mounting sleeve 6, a support block 30 matching the transmission assembly is slidably connected to the middle position of the auxiliary protective leg 28, a guide sleeve 33 is fixedly connected to one end of the support block 30 close to the joint 4, and the lower end of the guide sleeve 33 is open.

[0033] The lithium battery slurry viscosity testing device of the present invention, when installing the rotor 5, first place the rotor 5 in the slot 24, then push the rotor 5 and the lower end protection leg 12 upward together, during the upward movement of the lower end protection leg 12, the support block 30 on the auxiliary protection leg 28 will be driven by the pushing assembly and the transmission assembly to move toward the direction of the joint 4 until the guide sleeve 33 fixedly connected to the support block 30 is closed, and the closed guide sleeve 33 will restrict the joint 4 to keep the joint 4 in a vertical state, and at this time, the top of the rotor 5 will contact the bottom of the joint 4, and then the rotor 5 is rotated alone to make the rotor 5 and the joint 4 threadedly connected. That is, after the rotor 5 is connected to the joint 4, the lower end protective leg 12 is loosened, and the lower end protective leg 12 will move downward under the action of gravity. When the lower end protective leg 12 moves downward, the pushing assembly will drive the supporting block 30 on the auxiliary protective leg 28 to move away from the joint 4 through the transmission assembly, so as to avoid the guide sleeve 33 from affecting the operation of the joint 4 or the rotor 5.

[0035] As a preferred technical solution of the present invention, the transmission assembly includes a driving gear 9, a connecting shaft 10, a driven gear 11, an anti-slip block 35, a push block 36, and a transverse tooth block 38. The connecting shaft 10 is rotatably connected to the middle position of the upper protective leg 7, the driving gear 9 is fixedly connected to one end of the connecting shaft 10 close to the vertical tooth block 21, the driving gear 9 is meshed with the vertical tooth block 21, the driven gear 11 is fixedly connected to one end of the connecting shaft 10 away from the vertical tooth block 21, and an anti-slip groove 39 matching the anti-slip block 35 is provided on one side of the upper protective leg 7. The anti-slip block 35 is slidably connected to the anti-slip groove 39, one side of the anti-slip block 35 is fixedly connected to the push block 36, the transverse tooth block 38 is fixedly connected to the bottom of the push block 36, and the transverse tooth block 38 is meshed with the driven gear 11.

[0036] As a preferred technical solution of the present invention, the support block 30 is located on the push block 36 and is in sliding contact with the push block 36. A connecting groove 34 is provided on the side of the support block 30 close to the push block 36.

An external pull elastic member 32 is sleeved on the outer side of one end of the sliding rod 31 close to the guide sleeve 33. One end of the external pull elastic member 32 close to the guide sleeve 33 is fixedly connected to the sliding rod 31, and the other end of the external pull elastic member 32 is fixedly connected to the auxiliary protective leg 28.

[0037] Specifically, when the lower protective leg 12 moves, the lower protective leg 12 will drive the connecting plate 20 to move, and the vertical tooth block 21 on the connecting plate 20 will drive the driving gear 9 to rotate, and the driving gear 9 will drive the driven gear 11 to rotate through the connecting shaft 10, and the driven gear 11 will push the transverse tooth block 38 to move, and the transverse tooth block 38 will drive the push block 36 to move. Since the push block 36 is connected to the support block 30, the support block 30 will drive the guide sleeve 33 to move together.

[0038] As a preferred technical solution of the present invention, a rotating block 27 is provided between the two auxiliary protective legs 28 , the auxiliary protective legs 28 are connected to the rotating block 27 via fixing bolts 29 , and a rotating groove 26 matching the rotating block 27 is provided on the outer wall of the mounting sleeve 6 .

[0039] Specifically, if the operator has sufficient experience in installing the rotor 5 and does not need the guide sleeve 33 to restrict the joint 4 and the rotor 5, the operator can use a tool to remove the fixing bolt 29 and then remove the auxiliary protective leg 28. Since the support block 30 and the guide sleeve 33 and other structures are located on the auxiliary protective leg 28, the operator can use the traditional installation method to install the rotor 5 after removing the auxiliary protective leg 28.

[0040] As a preferred technical solution of the present invention, a group of limit blocks 40 are fixedly connected to the outer wall of the mounting sleeve 6, a protrusion 41 is fixedly connected to the top of the rotating block 27, and a magnetic block 42 that is attracted to the limit blocks 40 is fixedly connected to the middle position of the protrusion 41.

[0041] Specifically, after the rotor 5 is installed, the auxiliary protective leg 28 can be rotated so that the auxiliary protective leg 28 is vertical to the upper protective leg 7 and the lower protective leg 12. This improves the protective effect of the upper protective leg 7 and the lower protective leg 12, and can also reduce the impact of the echo effect on the rotor 5, making the main unit 2 measure more accurately.

[0043] Specifically, when the rotor 5 and the lower end protective leg 12 are pushed upward to a suitable position (this position refers to the position of the rotor 5 and the lower end protective leg 12 when the guide sleeve 33 is closed), the lower end hook 18 will be hooked together with the upper end hook 8, so that even if the operator releases the lower end protective leg 12, the lower end protective leg 12 will not move downward due to gravity. After the rotor 5 is connected to the joint 4, the lower end hook 18 can be pushed by the shift block 19 to stagger the lower end hook 18 with the upper end hook 8, and under the action of gravity, the lower end protective leg 12 will return to its original position.

[0044] As a preferred technical solution of the present invention, elastic blocks 25 are fixedly connected to both ends of the slot 24. The elastic blocks 25 restrict the rotor 5 to prevent the rotor 5 from escaping from the slot 24 by itself.

[0045] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
