Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. Moreover, in the description of this utility model, "at least one" means one or more, unless otherwise explicitly specified.

[0026] In this specification, the term "as an alternative embodiment" means that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one alternative embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same implementation or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0027] Combination Figure 1 and Figure 3 As shown, a first aspect of this embodiment provides a brake device, including: a fixed base (not shown in the figure), a rotating shaft 10, a brake disc 20, and a brake assembly 30, wherein:

[0028] Both the rotating shaft 10 and the braking assembly 30 are mounted on a fixed base. The rotating shaft 10 can rotate relative to the fixed base around its own axis. The brake disc 20 is mounted on the rotating shaft 10. When the rotating shaft 10 rotates around its own axis, the rotating shaft 10 can drive the brake disc 20 to rotate relative to the fixed base.

[0029] The braking assembly 30 includes a brake 31 disposed at one end of the brake disc 20 in the radial direction. The brake 31 has a first groove 311 through which the brake disc 20 can pass. The brake 31 also includes a brake part (not shown in the figure), which can move in the axial direction and extend into the first groove 311 to engage the brake disc 20 and brake the brake disc 20.

[0030] The brake device provided in this embodiment has a brake at one end of the brake disc in the radial direction. The brake has a first groove, allowing the brake disc to pass through the brake during rotation without affecting its rotation. The brake part inside the brake can extend into the first groove to engage the brake disc and brake it. This brake device can serve as an auxiliary brake for the motor, providing synchronous braking compensation when the motor locks up, reducing the braking pressure on the motor, lowering the risk of wear or damage during emergency stops, extending the motor's service life, and improving the safety and reliability of emergency stops. Furthermore, the brake device provided in this embodiment has a simple structure, is easy to install and adjust, which helps reduce manufacturing and maintenance costs and increase enterprise benefits.

[0031] In this embodiment, the rotating shaft 10 also includes a bushing disposed outside it. The bushing and the rotating shaft 10 are connected by a bearing. The bushing is disposed on a fixed seat, and the rotating shaft 10 can rotate relative to the bushing, so that the rotating shaft 10 is disposed on the fixed seat and the rotating shaft 10 can rotate relative to the fixed seat around its own axis.

[0032] Based on the above embodiments, as an optional implementation method, combined with Figure 4 and Figure 5 As shown, the brake 31 also includes a housing 312, on which a first groove 311 extending radially is provided. Two brake parts are disposed within the housing 312, and the two brake parts are arranged opposite each other in the axial direction, with the first groove 311 located between the two brake parts. The two brake parts can move relative to each other or move away from each other in the axial direction. When the two brake parts move relative to each other in the axial direction, they extend into the first groove 311 to engage the brake disc 20 and brake it. When the two brake parts move away from each other in the axial direction, they release the brake disc 20, allowing it to continue rotating. Thus, by providing two brake parts within the housing 312, the brake disc 20 can be braked more effectively.

[0033] Based on the above embodiments, as an optional implementation, friction pads are provided at the ends of both brake units opposite to the brake disc 20. This increases the friction between the brake unit and the brake disc 20 when the brake unit applies pressure, thereby improving braking efficiency.

[0034] Based on the above embodiments, as an optional implementation, the brake 31 is a pneumatic brake. An air inlet pipe 313 is provided at the end of the housing 312 facing away from the brake disc 20. The air inlet pipe 313 is connected to two brake units. High-pressure gas is injected into the brake units through the air inlet pipe 313. The two brake units move relative to each other in the axial direction under pressure. The friction pads of both brake units contact the brake disc 20, engaging it to brake the brake disc 20. When the injection of high-pressure gas into the brake units stops, the two brake units can move away from each other in the axial direction and return to their original positions. Therefore, using a pneumatic brake 31 makes it easier to adjust the braking force, and the pneumatic brake can provide timely and stable control, further reducing the risk of wear or damage during emergency motor stops.

[0035] It should be noted that the specific structure and working principle of the pneumatic brake are not further limited or explained in this embodiment, and those skilled in the art can make selections and adjustments according to the actual situation.

[0036] Based on the above embodiments, as an optional implementation method, combined with Figure 7 As shown, the braking assembly 30 also includes a mounting block 32 and a first locking member (not shown in the figure). The mounting block 32 has at least one first through hole 321, which extends axially through the mounting block 32. The first locking member passes through the first through hole 321 to lock the mounting block 32 onto the fixed seat. The mounting block 32 is connected to the brake 31, thereby fixing the brake 31 onto the fixed seat. As an optional embodiment, the mounting block 32 has two first through holes 321, which are respectively located at both ends of the mounting block 32. Therefore, by providing two first through holes 321, the stability of the connection between the mounting block 32 and the fixed seat can be improved, thereby improving the stability of the connection between the brake 31 and the fixed seat.

[0037] Based on the above embodiments, as an optional implementation, the mounting block 32 is further provided with at least one adjustment hole 322, which penetrates the mounting block 32 radially and is either oblong or elliptical. Alternatively, the mounting block 32 is provided with two sets of adjustment holes 322, respectively located at both ends of the mounting block 32. Each set of adjustment holes 322 includes two adjustment holes 322 arranged axially. Therefore, by providing two sets of adjustment holes 322, the stability and reliability of adjustment are improved, preventing the position of the brake 31 from shifting.

[0038] Based on the above embodiments, as an optional implementation method, combined with Figure 3As shown, the braking assembly 30 also includes a limiting block 33, which is disposed between the mounting block 32 and the brake 31. The limiting block 33 is fixedly connected to the brake 31, locked to the mounting block 32, and the limiting block 33 can move along the axial direction through the adjusting hole 322 to adjust the position of the brake 31 in the axial direction. Specifically, the braking assembly 30 further includes a second locking member and a third locking member. The limiting block 33 includes a first limiting part 331 and a second limiting part 332. The first limiting part 331 and the second limiting part 332 form an L-shaped limiting block 33. The first limiting part 331 contacts the upper end of the housing 312. At least one second through hole 331a is provided on the first limiting part 331. The second through hole 331a penetrates the first limiting part 331 in the axial direction. A blind hole 312a is provided at the upper end of the housing 312. The second locking member passes through the second through hole 331a and extends into the blind hole 312a to lock the brake 31 and the limiting block 33. The second limiting part 332 contacts the side of the housing 312. At least one third through hole 332a is provided on the second limiting part 332. The third through hole 332a passes through the second limiting part 332 in the radial direction. The third locking member passes through the third through hole 332a and the adjusting hole 322 to lock the limiting block 33 and the mounting block 32. The third locking member can move in the adjusting hole 322 to drive the limiting block 33 to move in the axial direction, so as to drive the brake 31 to move in the axial direction. Therefore, by setting the L-shaped limiting block 33, the position of the brake 31 in the axial direction can be restricted, so as to avoid the brake 31 from shifting position during operation and affecting the next braking of the brake disc 20. By adjusting the position of the brake 31 in the axial direction through the limiting block 33 and the adjusting hole 322, the installation error of the brake disc 20 can be compensated, ensuring that there is a certain gap between the brake disc 20 and the brake 31 when not braking, so that when the brake disc 20 rotates through the first groove 311, the brake disc 20 and the brake 31 do not contact each other, so as to avoid affecting the rotation of the brake disc 20.

[0039] Based on the above embodiments, as an optional implementation, the number of the second through hole 331a and the blind hole 312a are both two, to improve the stability of the connection between the limit block 33 and the brake 31. The number of the third through hole 332a is the same as the number of the adjustment hole 322, and the third through hole 332a and the adjustment hole 322 are arranged in a one-to-one correspondence. The first through hole 321, the second through hole 331a, the third through hole 332a and the blind hole 312a can all be set as threaded holes, and the first locking member, the second locking member and the third locking member can all be threaded members.

[0040] Based on the above embodiments, as an optional implementation method, combined with Figure 5 and Figure 6As shown, a protrusion 314 is provided on the side surface of the housing 312 of the brake 31 that contacts the limiting block 33. The protrusion 314 extends in the axial direction. A second groove 332b is provided on the second limiting part 332 that cooperates with the protrusion 314. When the brake 31 contacts the limiting block 33, the protrusion 314 is engaged in the second groove 332b. Thus, the protrusion 314 and the second groove 332b can limit the position of the brake 31 in the horizontal direction and prevent the brake 31 from shifting in the horizontal direction.

[0041] The second aspect of this embodiment provides a lithium battery assembly line including the braking device described in the first aspect. The lithium battery assembly line is a cylindrical lithium battery assembly line, and the braking device is used in a turret-type model of the cylindrical lithium battery assembly line. The cylindrical lithium battery assembly line includes a gear 40 and a motor. The braking device is mounted on the gear 40, and the motor is driven by the gear 40. Therefore, the braking device can serve as an auxiliary brake for the motor, providing synchronous braking compensation when the motor locks up, reducing the braking pressure on the motor, lowering the risk of wear or damage during emergency stops, extending the motor's service life, and improving the safety and reliability of emergency stops.

[0042] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
