Description

Technical Field

[0001] This invention relates to the field of brake assembly technology, and more specifically, to a feeding structure, brake assembly system and method. Background Technology

[0002] In the brake assembly process, installing the retaining ring into the brake mounting slot is a key step. To improve assembly efficiency, this step has gradually adopted mechanized operations. In existing technology, the mechanized retaining ring installation system mainly consists of a feeding assembly and a pushing assembly, which work together to complete the supply and installation of the retaining ring. The core function of the feeding assembly is to store the retaining rings to be installed and provide a stable conveying channel, ensuring that the retaining rings are arranged in an orderly manner and in an initial position that can be pushed. The pushing assembly, as the power actuation component, receives the work command and pushes the retaining rings from the initial position in the feeding assembly to the designated position corresponding to the brake mounting slot through its own pushing action, ultimately assisting in the installation of the retaining ring on the brake.

[0003] Due to its inherent structural characteristics, the snap ring has a notch at one end. This structure results in an uneven weight distribution, with the notched end (usually the left) being lighter and the unnotched end (usually the right) being heavier. This causes the snap ring to tilt, with the left side higher than the right, when placed within the feeding assembly's conveying channel (which is rod-shaped, with the snap ring fitted around its outer periphery). When the pushing unit of the pushing assembly applies a pushing force to the snap ring in this tilted position, it can only push from the closed end towards the open end to separate the snap ring from the rod. When the snap ring is tilted, it easily gets stuck with the rod. Further pushing in this direction will cause the inner wall of the snap ring near the closed end to remain in contact with the rod, preventing further movement. This problem of the snap ring getting stuck within the feeding assembly affects its normal transport and the smooth progress of subsequent installation procedures. Summary of the Invention

The pushing unit drives the spring-loaded unit to move away from the feeding assembly until the top of the spring-loaded unit is lower than the bottom of the pushing unit, so that the top surface of the bottommost retaining spring is lower than the bottom of the feeding assembly. Then the pushing unit drives the retaining spring to pass through the set space along the pushing direction.

[0024] In some embodiments, the brake assembly system further includes a positioning component, which includes a positioning unit, an upper clamping unit, and a lower clamping unit; the positioning unit is disposed at one end of the material support unit along its length; the upper clamping unit is disposed on the side of the positioning unit closer to the material supply component; and the lower clamping unit is disposed on the side of the positioning unit away from the material supply component.

[0025] The first working state also includes the positioning unit supporting the brake housing, the upper clamping unit applying a force to the brake housing toward the positioning unit, and the lower clamping unit keeping the mounting groove located on the side of the mounting hole closer to the feeding assembly.

[0026] In some embodiments, the feeding assembly includes a slide rail unit; the slide rail unit includes a slide rail body and a retainer; the slide rail body is connected to the retainer; N≤Q<M≤P; where M is the maximum dimension of the retainer along the width direction of the material support unit, N is the maximum dimension of the slide rail body along the width direction of the material support unit, P is the maximum dimension of the inner peripheral wall of the retaining spring along the width direction of the material support unit, and Q is the maximum dimension of the opening of the retaining spring along the width direction of the material support unit;

[0028] In some embodiments, the pushing unit includes a pushing rod and a pushing head; the pushing rod is connected to the pushing head; the pushing rod and the pushing head are arranged sequentially along the pushing direction; the pushing head is adapted to the outer peripheral surface of the closed end of the retaining spring;

[0029] The second working state also includes the pusher head abutting against the outer peripheral surface of the closed end of the retaining spring, driving the retaining spring to move along the pusher direction.

[0030] Thirdly, the present invention discloses a brake assembly method, wherein the brake assembly method is applied to a brake assembly system as described in any of the second aspects, and the brake assembly method includes:

[0031] Based on the positioning completion, the pushing unit drives the rebound unit to move until the top of the rebound unit is lower than the bottom of the pushing unit and the top surface of the bottommost retaining spring is lower than the bottom of the feeding assembly; wherein, the positioning completion includes the retaining spring being sleeved on the outer periphery of the feeding assembly, the unopened end of the bottommost retaining spring abutting against the top of the rebound unit, the unopened end of the retaining spring being higher than the open end of the retaining spring, the pushing unit being disposed on one side of the unopened end of the retaining spring, and the material support unit and the brake housing being arranged sequentially along the pushing direction;

[0032] The pushing unit drives the retaining spring to move toward the mounting groove;

[0033] The installation is complete because the retaining ring is detachably connected to the outer periphery of the mounting slot.

[0034] To solve the problem of the retaining spring easily getting stuck when the pusher unit pushes it, the present invention has the following advantages:

[0035] Through the coordinated action of the feeding assembly and the pushing assembly (including the supporting unit, the spring-loaded unit, and the pushing unit), based on the feeding assembly and the supporting unit being spaced apart from top to bottom and the pushing unit and the supporting unit being slidably connected, the spring-loaded unit, by moving towards or away from the feeding assembly, first makes the left end of the retaining spring higher than the right end, correcting the left-high-right-low tilt state of the retaining spring caused by its own notch. When the pushing unit moves along the pushing direction (rightward), the pushing unit first drives the spring-loaded unit to move away from the feeding assembly, so that the top of the spring-loaded unit gradually descends to below the bottom of the pushing unit. During this process, the right side of the retaining spring abuts the supporting groove of the supporting unit before the left side, thereby achieving stable adjustment of the retaining spring's posture during the pushing process. This avoids the abnormal increase in friction caused by the retaining spring's tilt and uneven contact with the feeding assembly when the pushing unit pushes the retaining spring, ultimately solving the problem of the retaining spring getting stuck in the feeding assembly, ensuring that the retaining spring smoothly passes through the set space between the feeding assembly and the supporting unit, and ensuring that subsequent installation procedures are carried out in an orderly manner.

[0047] During the assembly of the brake, the retaining ring has a notch at one end, resulting in an uneven weight distribution with the right end being heavier. This causes the retaining ring to tilt on the feeding assembly, with the left side higher than the right. When the pushing unit pushes the retaining ring in this tilted position along the pushing direction, uneven contact easily occurs between the retaining ring and the feeding assembly, which can lead to jamming and affect the normal operation of the feeding structure.

[0048] Example 1: This example discloses a feeding structure, such as... Figure 1 As shown, the feeding structure includes a feeding component 20 and a pushing component 30. The feeding component 20 can realize the storage and initial positioning of the snap ring 53, providing basic support for the subsequent conveying of the snap ring 53, and achieving the effect of ensuring the orderly supply of the snap ring 53.

[0049] The feeding assembly 30 includes a material support unit 31, a springback unit 32, and a feeding unit 33. Through the combination of the material support unit 31, the springback unit 32, and the feeding unit 33, the feeding assembly 30 can achieve coordinated functions of lifting, adjusting the posture, and pushing the snap ring 53, thereby providing multi-stage protection for the entire feeding process of the snap ring 53 and ultimately achieving the effect of stable feeding of the snap ring 53. The feeding assembly 20 and the supporting unit 31 are spaced apart from top to bottom, forming a space between the feeding assembly 20 and the supporting unit 31 to accommodate the movement of the retaining spring 53 and the pushing unit 33, reserving a channel for the conveying of the retaining spring 53 and the movement of the pushing unit 33; the pushing unit 33 and the supporting unit 31 are slidably connected; the springback unit 32 is connected to the supporting unit 31; at least part of the springback unit 32 moves in a direction closer to or away from the feeding assembly 20. By moving the springback unit 32 in a direction closer to or away from the feeding assembly 20, the support height of the retaining spring 53 can be adjusted, so that the closed end of the retaining spring 53 is higher than the open end of the retaining spring 53, correcting the tilting state of the retaining spring 53 caused by uneven weight, and ultimately solving the problem of the retaining spring 53 being stuck; Figure 3 As shown, the pushing unit 33 moves along the length of the supporting unit 31 on the side of the supporting unit 31 near the feeding component 20, so that the pushing unit 33 is close to the area where the retaining spring 53 is located, and the movement along the length of the supporting unit 31 can accurately align with the pushing path of the retaining spring 53; the top of the rebound unit 32 and the feeding component 20 move along the pushing direction of the pushing unit 33 (i.e., as shown) Figure 5 As shown in the direction from right to left, the feeding component 20 and the material support unit 31 are arranged in sequence; the minimum distance between the feeding component 20 and the material support unit 31 is greater than or equal to the thickness of the pushing unit 33, so as to ensure that the pushing unit 33 can pass smoothly through the space between the feeding component 20 and the material support unit 31, and to avoid the pushing unit 33 being unable to move due to insufficient distance.

[0050] The feeding structure includes a first working state and a second working state. In the first working state, the top of the springback unit 32 is higher than the bottom of the feeding assembly 20, and the pushing unit 33 is located on the side of the springback unit 32 away from the feeding assembly 20. The minimum distance between the top of the springback unit 32 and the bottom of the feeding assembly 20 is within a first set range, which can be 3mm-5mm, to prevent the retaining spring 53 from jamming and failing to push. Figure 6 As shown, the left side of the bottom retaining spring 53 abuts against the top surface of the material support unit 31, and the right side of the bottom retaining spring 53 abuts against the top of the spring return unit 32, so that the left side of the retaining spring 53 is higher than the right side, so that the retaining spring 53 will not get stuck with the material supply due to uneven weight of the retaining spring 53.

[0051] The second working state includes the pushing unit 33 moving along the pushing direction, first driving the springback unit 32 to move away from the feeding component 20 until the top of the springback unit 32 is lower than the bottom of the pushing unit 33, and then the pushing unit 33 passes through the set space; wherein, the set space is the space between the feeding component 20 and the supporting unit 31 in the vertical direction. By moving the pushing unit 33 along the pushing direction and first driving the springback unit 32 to move down until its top is lower than the bottom of the pushing unit 33, the pushing unit 33 can avoid interference from the springback unit 32 before pushing, and at the same time, the right side of the retaining spring 53 moves down, and the upper surface of the retaining spring 53 is lower than the bottom of the feeding component 20. Then, the pushing unit 33 pushes the retaining spring 53 through the set space, completing the pushing of the retaining spring 53, and finally solving the problem of the retaining spring 53 getting stuck when pushing.

[0052] Furthermore, the spring-loaded unit 32 includes an elastic part 321, a spring-loaded body 322, a first spring-loaded head 323, and a second spring-loaded head 324. One end of the elastic part 321 abuts against the material support unit 31, and the other end abuts against the spring-loaded body 322, so that the elastic part 321 provides elastic support for the spring-loaded body 322, realizing the automatic reset of the spring-loaded body 322 and ensuring the reusability of the spring-loaded unit 322. The spring-loaded body 322 is slidably connected to the material support unit 31, so that the spring-loaded body 322 moves stably along the material support unit 31, avoiding the spring-loaded body 322 from deviating and ensuring the precise movement of the spring-loaded body 322. The spring-loaded body 322 moves in the up and down direction to adjust the height of the first spring-loaded head 323 and the second spring-loaded head 324, thereby realizing the adjustment of the support height of the retaining spring 53 and achieving the effect of ensuring the adjustment of the retaining spring 53's posture. The first spring-loaded head 323 and the second spring-loaded head 324 are... The second rebound head 324 is positioned on the side of the first rebound head 323 near the feeding assembly 20, allowing the second rebound head 324 to preferentially cooperate with the feeding assembly 20, while the first rebound head 323 cooperates with the pushing unit 33, achieving an orderly connection between the various cooperative actions; the top surface of the first rebound head 323 gradually increases in height along the pushing direction, so that when the pushing unit 33 moves along the pushing direction and abuts against the top surface of the first rebound head 323, it can smoothly drive the first rebound head 323 downward, avoiding collision between the pushing unit 33 and the rebound head; the top surface of the second rebound head 324 gradually decreases in height along the pushing direction; the distance between the top of the first rebound head 323 and the top of the second rebound head 324 in the vertical direction is within a second set range, which can be 0mm to 3mm, to reduce damage to the pushing unit 33;

[0053] The first working state also includes the top of the spring-loaded unit 32 being higher than the bottom of the feeding assembly 20 and the top surface of the second spring-loaded head 324 abutting against the bottom of the feeding assembly 20; in the first working state, the top of the spring-loaded unit 32 being higher than the bottom of the feeding assembly 20 can support the retaining spring 53, and the abutting between the second spring-loaded head 324 and the bottom of the feeding assembly 20 can limit the upward movement of the second spring-loaded head 324. Figure 5As shown, the right side of the bottommost retaining ring 53 abuts against the top of the spring-loaded unit 32, thus making the retaining ring 53 higher on the left and lower on the right.

[0054] The second working state also includes the pushing unit 33 moving along the pushing direction. First, it drives the return unit 32 to move away from the feeding component 20 until the top of the first return head 323 and the top of the second return head 324 are respectively lower than the bottom of the pushing unit 33. Then, the pushing unit 33 passes through the set space. By driving the first return head 323 and the second return head 324 to move down below the bottom of the pushing unit 33, the first return head 323 and the second return head 324 can be prevented from obstructing the movement of the pushing unit 33, so that the pushing unit 33 can push the retaining ring 53 smoothly through the set space, thus ensuring that the pushing unit 33 can push the retaining ring 53 normally.

[0055] Furthermore, such as Figure 6 As shown, A < B; where A is the minimum angle between the top surface of the first rebound head 323 and the top surface of the material support unit 31, and B is the minimum angle between the top surface of the second rebound head 324 and the top surface of the material support unit 31. The first rebound head 323 has a small tilt angle, which allows the pushing unit 33 to drive the rebound head downward slowly, avoiding damage to the retaining spring 53 after a steep drop due to excessive downward movement. The second rebound head 324 has a large tilt angle, which can shorten the length of the second rebound head 324 while maintaining the height of the top of the second rebound head 324. This allows the rebound unit 32 to maintain a height above the bottom of the feeding assembly 20 even with a smaller length dimension. The two work together to achieve the effect of balancing the protection of the retaining spring 53 and the compact structure of the rebound unit 32.

[0056] Furthermore, such as Figure 3 As shown, the material support unit 31 includes a material support platform 311, a material support groove 312, and a limiting part 313; the material support platform 311 is disposed at the bottom end of the pushing unit 33; the material support platform 311 is spaced apart from the feeding component 20 to avoid interference between the material support platform 311 and the feeding component 20, and to reserve space for the conveying of the snap ring 53; the material support groove 312 is formed by recessing from the top end of the material support platform 311 toward the bottom end of the material support platform 311; the rebound unit 32 is disposed in the material support groove 312, so that the rebound unit 32 moves stably within the material support groove 312, and keeps the rebound unit 32 moving along the material support groove 312. Figure 5The spring unit 32 moves in the up and down direction as shown, ensuring the precise operation of the spring unit 32; at least part of the spring unit 32 is slidably connected to the material support groove 312, allowing the spring unit 32 to move smoothly along the material support groove 312 and reducing movement resistance; the limiting part 313 is connected to the material support table 311, and the limiting part 313 is connected to the top of the material support table 311; the limiting part 313 and the spring unit 32 are arranged sequentially along the pushing direction; part of the pushing unit 33 is arranged between the limiting part 313 and the material support table 311, and the limiting part 313 can limit the pushing unit 33, restricting the pushing unit 33 from moving away from the spring unit 32, and keeping the pushing unit 33 between the feeding unit and the material support unit 31;

[0057] The second working state also includes the following: when the pusher unit 33 drives the springback unit 32 to move to a position where the top of the springback unit 32 is lower than the bottom of the pusher unit 33, the limiting part 313 applies a force to the pusher unit 33 in the direction of the support table 311. By applying a force in the direction of the support table 311 through the limiting part 313, the upward movement range of the pusher unit 33 can be limited, avoiding interference with the feeding component 20 caused by the upward movement of the pusher unit 33, thus ensuring the normal pushing effect of the pusher unit 33.

[0058] Example 2: This example discloses a brake 50 assembly system. The brake 50 assembly system includes any of the feeding structures described in Example 1, and further includes:

[0059] The retaining ring 53 of the brake 50 is configured as an annular body with one end open, which facilitates the retaining ring 53 to be sleeved and installed on the target component;

[0060] The minimum vertical distance between the feeding component 20 and the material support unit 31 is greater than or equal to the maximum dimension of one snap ring 53 along its own axis and less than the maximum dimension of two snap rings 53 along their own axis, ensuring that only one snap ring 53 can pass through between the feeding component 20 and the material support unit 31 at a time, avoiding jamming caused by multiple snap rings 53 being conveyed at the same time.

[0061] The first working state also includes the snap ring 53 being sleeved on the outer periphery of the feeding assembly 20, with the bottommost snap ring 53 being the unopened end (i.e., as shown in the image). Figure 5 The right side shown abuts against the top of the spring-loaded unit 32. The closed end of the retaining spring 53 is higher than the open end of the retaining spring 53. The pushing unit 33 is located on one side of the closed end of the retaining spring 53. The closed end of the retaining spring 53 and the open end of the retaining spring 53 on the feeding assembly 20 are arranged sequentially along the pushing direction. In the first working state, the retaining spring 53 can be initially positioned by being sleeved on the outer periphery of the feeding assembly 20. The closed end abuts against the spring-loaded unit 32 and is higher than the open end, which can correct the tilt posture of the retaining spring 53. The pushing unit 33 is located on one side of the closed end, which can facilitate subsequent pushing. Together, they achieve the effect of preparing for the pushing of the retaining spring 53.

[0062] The second working state also includes the direction of the pusher unit 33 along the unopened end of the retaining spring 53 to the open end of the retaining spring 53 (i.e., as shown in the image). Figure 5 As shown on the left, the pushing unit 33 drives the springback unit 32 to move away from the feeding assembly 20 until the top of the springback unit 32 is lower than the bottom of the pushing unit 33, so that the top surface of the bottommost retaining spring 53 is lower than the bottom of the feeding assembly 20. Then, the pushing unit 33 drives the retaining spring 53 to pass through the set space along the pushing direction. By moving the pushing unit 33 in a specific direction and driving the springback unit 32 to move downward, the top surface of the retaining spring 53 can be lower than the bottom of the feeding assembly 20, avoiding the feeding assembly 20 from obstructing the movement of the retaining spring 53. Then, the retaining spring 53 is driven to pass through the set space, achieving the effect of successfully pushing the retaining spring 53.

[0063] Furthermore, the brake 50 also includes a brake housing unit 51 and a piston unit 52; the brake housing unit 51 includes a brake housing 511 and a mounting hole 512. The brake housing 511 provides a mounting base for the various components of the brake 50, and the mounting hole 512 facilitates the passage of the piston rod 522, ensuring the proper fit between the piston unit 52 and the brake housing unit 51; the mounting hole 512 penetrates the brake housing 511, ensuring that the piston rod 522 can completely pass through the brake housing 511, thus avoiding obstruction of the piston rod 522's movement; Figure 4 As shown, the piston unit 52 includes a piston body 521, a piston rod 522, and a mounting groove 523. The piston body 521 and the piston rod 522 cooperate to realize the braking action of the brake 50. The mounting groove 523 can be used to install the snap ring 53. The outer peripheral wall of the piston body 521 is slidably connected to the inner peripheral wall of the brake housing 511, so that the piston body 521 slides stably along the inner wall of the brake housing 511, ensuring smooth braking action. The outer peripheral wall of the piston rod 522 is slidably connected to the inner peripheral wall of the piston body 521, so that the piston rod 522 slides along the inner wall of the piston body 521, realizing the extension and retraction action of the piston rod 522. The piston rod 522 passes through the mounting hole 512. The mounting groove 523 is recessed from the outer peripheral wall of the piston rod 522 toward the central axis of the piston rod 522. The mounting groove 523 is located on the side of the mounting hole 512 away from the piston body 521, so that the snap ring 53 can limit the piston rod 522 after installation, preventing the piston rod 522 from moving excessively.

[0064] The first working state also includes the material support unit 31 and the brake 50 arranged in sequence along the pushing direction, so that when the material push unit 33 pushes the snap ring 53 along the pushing direction, it can directly transport the snap ring 53 to the brake 50, thereby shortening the conveying path of the snap ring 53 and improving the installation efficiency.

[0065] The second working state also includes the pusher unit 33 driving the retaining ring 53 to move to the installation state along the pusher direction; wherein, the installation state includes the retaining ring 53 being sleeved on the outer periphery of the installation groove 523, and the projection area of ​​the installation hole 512 toward the installation groove 523 coinciding with part of the retaining ring 53, so that the retaining ring 53 can fix the relative position of the brake housing 511 and the piston rod 522.

[0066] Furthermore, such as Figure 2 As shown, the brake 50 assembly system also includes a positioning component 10, which includes a positioning unit 11, an upper clamping unit 12, and a lower clamping unit 13. The positioning unit 11 is located at one end of the material support unit 31 along its length. The material support unit 31 and the positioning unit 11 are arranged sequentially along the pushing direction, so that the positioning unit 11 cooperates with the material support unit 31 to form a continuous path for the retaining spring 53 to be conveyed from the material support unit 31 to the brake 50. The upper clamping unit 12 is located on the side of the positioning unit 11 close to the feeding component 20 to prevent the positioning unit 11 from shifting. The lower clamping unit 13 is located on the side of the positioning unit 11 away from the feeding component 20. The lower clamping unit 13 can support and limit the brake 50 components from below to ensure the overall stability of the brake 50.

[0067] Preferably, the positioning unit 11 includes a positioning platform 111 and a positioning seat 112, with the positioning platform 111 connected to the positioning seat 112. The upper clamping unit 12 includes a first driving part 121 and an upper clamping head 122, with the first driving part 121 and the upper clamping head 122 drivenly connected to clamp the brake 50. The lower clamping unit 13 includes a second driving part and a lower clamping head 131, with the second driving part and the lower clamping head 131 drivenly connected to clamp the bottom end of the brake 50. The feeding assembly 20 also includes a vibration unit 21, which provides vibration to the feeding assembly 20 so that the retaining spring 53 can slide smoothly on the slide rail unit 22.

[0068] The first working state also includes the positioning unit 11 supporting the brake housing 511, the upper clamping unit 12 applying a force to the brake housing 511 in the direction of the positioning unit 11, the upper clamping unit 12 and the positioning unit 11 together realize the positioning and clamping of the brake housing 511, and the lower clamping unit 13 keeping the mounting groove 523 located on the side of the mounting hole 512 close to the feeding assembly 20.

[0069] Furthermore, the feeding assembly 20 includes a slide rail unit 22; the slide rail unit 22 includes a slide rail body 221 and a retainer 222; the slide rail body 221 is connected to the retainer 222, and the combination of the slide rail body 221 and the retainer 222 can support and limit the retaining spring 53, preventing the retaining spring 53 from falling off during conveying; such as Figure 8As shown, N≤Q<M≤P; where M is the maximum dimension of the catch 222 along the width direction of the material support unit 31, N is the maximum dimension of the slide rail 221 along the width direction of the material support unit 31, P is the maximum dimension of the inner peripheral wall of the snap ring 53 along the width direction of the material support unit 31, and Q is the maximum dimension of the opening of the snap ring 53 along the width direction of the material support unit 31; the slide rail 221 passes through the opening of the snap ring 53, and the catch 222 supports the inner peripheral wall of the snap ring 53, while ensuring that the catch 222 can limit the snap ring 53 without hindering its movement, thus achieving the effect of ensuring stable conveying of the snap ring 53 on the slide rail unit 22. By controlling the orientation of the opening of the snap ring 53, the snap ring 53 moves along the pushing direction until it leaves the set space, and then directly installs into the corresponding mounting slot 523 on the brake 50, connecting the snap ring 53 with the mounting slot 523.

[0070] The first working state also includes the inner peripheral wall of the retaining ring 53 being sleeved on the outer peripheral side of the retaining lug 222, the slide rail 221 being disposed in the opening of the retaining ring 53, and the portion of the retaining ring 53 on the side of the retaining lug 222 away from the slide rail 221 (i.e., the unopened end of the retaining ring 53, such as...) Figure 7 The weight of the portion of the retaining ring 53 (i.e., the open end of the retaining ring 53, as shown on the right) is greater than that of the portion of the retaining ring 222 near the slide rail body 221. Figure 7 The weight of the spring clip 53 (shown on the left) is as follows. The inner circumferential wall of the spring clip 53 is fitted with a clasp 222 to achieve initial positioning of the spring clip 53. The slide rail 221 is set in the opening to prevent the spring clip 53 from shifting. The weight difference of the spring clip 53 on both sides of the clasp 222 can help adjust the posture of the spring clip 53, so as to achieve the effect of ensuring that the spring clip 53 is stably placed on the feeding assembly 20.

[0071] Furthermore, the pushing unit 33 includes a pushing rod 331, a pushing head 332, and a third driving unit; the pushing rod 331 is connected to the pushing head 332, so that the driving force of the pushing rod 331 is transmitted to the pushing head 332, driving the pushing head 332 to move; the third driving unit is drivenly connected to the pushing rod 331, driving the pushing rod 331 to move. The pushing rod 331 and the pushing head 332 are arranged sequentially along the pushing direction; the side of the pushing head 332 near the retaining spring 53 is adapted to the outer peripheral surface of the unopened end of the retaining spring 53. The adaptation of the pushing head 332 to the outer peripheral surface of the retaining spring 53 can increase the contact area between the two, avoiding uneven force on the retaining spring 53 during pushing, which may cause displacement or damage, and achieving the effect of ensuring stable and intact pushing of the retaining spring 53;

[0072] The second working state also includes the pusher head 332 abutting against the outer peripheral surface of the closed end of the retaining spring 53, driving the retaining spring 53 to move along the pushing direction. By abutting against the closed end of the retaining spring 53, the driving force can be evenly transmitted to the retaining spring 53, causing the retaining spring 53 to move along the pushing direction, thus ensuring that the retaining spring 53 pushes accurately and smoothly.

[0073] Preferably, the brake 50 assembly system further includes a detection component 40, which includes a fourth drive unit 41 and a detection head 42. The fourth drive unit 41 is drivenly connected to the detection head 42. When the retaining ring 53 is installed on the brake 50, the detection head 42 can send a detection signal. By checking whether the detection signal can be blocked at the installation position of the retaining ring 53, it can be determined whether the retaining ring 53 is installed in the set position of the brake 50.

[0074] Example 3: This example discloses a brake 50 assembly method. The brake 50 assembly method is applied to any of the brake 50 assembly systems in Example 2. The brake 50 assembly method includes steps S10 to S30, and each step is described in detail below:

[0075] In step S10, based on the completion of positioning, the pushing unit 33 drives the springback unit 32 to move until the top of the springback unit 32 is lower than the bottom of the pushing unit 33 and the top surface of the bottommost retaining spring 53 is lower than the bottom of the feeding assembly 20. Positioning includes the retaining spring 53 being sleeved on the outer periphery of the feeding assembly 20, the closed end of the bottommost retaining spring 53 abutting against the top of the springback unit 32, the closed end of the retaining spring 53 being higher than the open end of the retaining spring 53, the pushing unit 33 being positioned on one side of the closed end of the retaining spring 53, and the material support unit 31 and the brake housing 511 being arranged sequentially along the pushing direction. Based on the completion of positioning, the pushing unit 33 drives the springback unit 32 to move down until its top is lower than the bottom of the pushing unit 33, thus preventing the springback unit 32 from obstructing the pushing unit 33. Simultaneously, the top surface of the retaining spring 53 is lower than the bottom of the feeding assembly 20, preventing the feeding assembly 20 from obstructing the retaining spring 53, achieving the effect of pushing and clearing obstacles for the retaining spring 53.

[0076] In step S20, the pushing unit 33 drives the retaining ring 53 to move toward the mounting groove 523, accurately delivering the retaining ring 53 to the installation position and ensuring the accurate installation path of the retaining ring 53;

[0077] In step S30, the retaining spring 53 is detachably connected to the outer periphery of the mounting slot 523. Once installed, this facilitates convenient installation and subsequent maintenance of the retaining spring 53, improving the assembly and maintenance convenience of the brake 50. By moving the pushing unit 33 along the pushing direction and first driving the return spring unit 32 downwards until its top is lower than the bottom of the pushing unit 33, the pushing unit 33 avoids interference from the return spring unit 32 before pushing. Simultaneously, the right side of the retaining spring 53 moves downwards, ensuring that the upper surface of the retaining spring 53 is lower than the bottom of the feeding assembly 20. Subsequently, the pushing unit 33 pushes the retaining spring 53 through the set space, completing the pushing of the retaining spring 53 and ultimately resolving the problem of jamming during pushing.

[0078] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
