Unless otherwise stated, the meaning of "multiple" is two or more.

[0021] In the process of storing the balls by using the storage assembly 10 and supplying the balls by using the counting assembly 20, when different numbers of balls are needed to adapt to the assembly requirements of different specifications of bearings, the prior art usually needs to change the inlet and outlet heights of the counting body 221 or change the minimum distance between the set output port of the storage assembly 10 and the blocking plate 23 to achieve this. This process needs to interrupt the assembly process, the operation steps are complicated, and at the same time, the overall structure of the ball supply mechanism is greatly changed, which will consume more time.

[0022] Example 1: This example discloses a ball feeding mechanism, such as Figure 4 As shown, the ball feeding mechanism includes a storage component 10 and a counting component 20. The storage component 10 is used to store the balls. The storage component 10 can centrally store the balls, providing a stable material source for the feeding process and solving the problem of scattered storage of balls that is difficult to manage.

[0023] like Figure 2 As shown, the counting assembly 20 includes a second driving part 21, a counting unit 22, and a blocking plate 23. The counting unit 22 includes a counting body 221 and a first channel 222. The second driving part 21 is driven and connected to the counting body 221. The set output port, the counting body 221, and the blocking plate 23 of the storage assembly 10 are arranged in sequence along the feeding direction. The first channel 222 passes through the counting body 221. The second driving part 21 provides power for the movement of the counting body 221. The set output port, the counting body 221, and the blocking plate 23 are arranged in sequence to ensure that the balls flow in sequence. During the movement of the counting unit 22, it abuts against the set output port and the blocking plate 23, so that the balls can enter the first channel 222 from the set output port. At the same time, the blocking plate 23 prevents the balls from leaving the first channel 222 prematurely. The first channel 222 passes through the counting body 221 to provide a space for the balls. A≥B. Where A is the length of the central axis of the first channel 222, and B is the minimum distance between the center point of the set output port of the storage assembly 10 and the blocking plate 23. B is a fixed value. By varying the length of the central axis of the first channel 222, it is possible to adapt to different ball count requirements without changing the distance between the center point of the set output port of the storage assembly 10 and the blocking plate 23, thus achieving convenient operation and ensuring counting accuracy. The end of the first channel 222 closest to the set output port is referred to as the first end, and the other end is referred to as the second end.

[0024] The ball feeding mechanism includes a first feeding state and a first discharging state. The first feeding state includes the balls passing through the set output port and the first end in sequence into the first channel 222, and the blocking plate 23 prevents the balls from leaving the first channel 222 through the second end. The first feeding state realizes the storage counting of the balls in the first channel 222, and the blocking plate 23 can ensure the accurate number of balls in the first channel 222. The first discharging state includes the second driving unit 21 driving the counter 221 to move, so that the set output port is disconnected from the first end, and the balls in the first channel 222 leave the first channel 222 through the second end. The first discharging state realizes the ball output by driving the counter 221 by the second driving unit 21 to move, ensuring the controllability of the feeding and ultimately meeting the ball requirements of the bearing assembly.

[0025] Further, the first feeding state further includes A>B, the first channel 222 is filled with the balls, and the top ball part is located in the set output port of the storage assembly 10, so that the set output port is in effective contact with the ball, lays a foundation for exerting force on the ball in subsequent feeding, and ensures the continuity of the ball output process. Among them, the top ball is the ball close to the first end in the first channel 222.

[0026] The first feeding state further includes that the inner wall of the set output port exerts force on the top ball in the feeding direction during the movement of the counting body 221. Because A>B, the first channel 222 is curved at this time, and the ball may be stuck in the curved part. When the counting body 221 moves, the inner wall of the set output port exerts force on the top ball in the feeding direction, which can push the ball to move in the feeding direction, avoid the ball being stuck in the curved part of the first channel 222, and realize smooth discharge of the ball from the first channel 222.

[0027] Further, in the first feeding state, 0

[0028] Further, the first feeding state further includes that the inner wall of the set output port exerts force on the top ball in the feeding direction during the movement of the counting body 221. Because A>B, the first channel 222 is curved at this time, and the ball may be stuck in the curved part. When the counting body 221 moves, the inner wall of the set output port exerts force on the top ball in the feeding direction, which can push the ball to move in the feeding direction, avoid the ball being stuck in the curved part of the first channel 222, and realize smooth discharge of the ball from the first channel 222.

[0029] Further, as shown in Figure 2 The counting unit 22 further includes a second channel 223. The second channel 223 penetrates the counting body 221. The second channel 223 is spaced apart from the first channel 222. E=A+PxD. Wherein E is the length of the center axis of the second channel 223, D is the diameter of the ball, and P is a positive integer. One end of the second channel 223 close to the set output port is the third end, and the other end is the fourth end. The setting of the second channel 223 increases the counting gear of the feeding mechanism, so that the second channel 223 can accommodate different numbers of balls than the first channel 222, and meets the diversified feeding demand.

[0030] The ball feeding mechanism further comprises a second feeding state and a second discharging state. In the second feeding state, the balls pass through the set output port and the third end into the second channel 223 in sequence, and the blocking plate 23 prevents the balls from leaving the second channel 223 through the fourth end. In the second discharging state, the second driving part 21 drives the counting body 221 to move, so that the set output port is disconnected from the first end and the third end respectively, the balls in the second channel 223 leave the second channel 223 through the fourth end, and the storage and output of the balls are independently completed through the second channel 223. The counting body 221 does not need to be replaced, and the switching of the communication of the set output port and different channels can be realized by moving the counting body 221 driven by the second driving part 21, which is convenient to operate and improves the feeding efficiency.

[0031] Further, the counting unit 22 can further comprise a third channel penetrating through the counting body 221. The third channel is arranged separately from the second channel 223 and the first channel 222. M=A+NxD. Wherein, M is the length of the central axis of the third channel, D is the diameter of the ball, and N is a positive integer and N≠P. One end of the third channel close to the set output port is the fifth end, and the other end is the sixth end. The arrangement of the third channel increases the counting gear of the feeding mechanism, so that the third channel can accommodate different numbers of balls than the first channel 222 and the second channel 223, and meets the diversified feeding demand.

[0032] The ball feeding mechanism further comprises a third feeding state and a third discharging state. In the third feeding state, the balls pass through the set output port and the fifth end into the third channel in sequence, and the blocking plate 23 prevents the balls from leaving the third channel through the sixth end. In the third discharging state, the second driving part 21 drives the counting body 221 to move, so that the set output port is disconnected from the first end, the third end and the fifth end respectively, the balls in the third channel leave the third channel through the sixth end, and the storage and output of the balls are independently completed through the third channel. The counting body 221 does not need to be replaced, and the switching of the communication of the set output port and different channels can be realized by moving the counting body 221 driven by the second driving part 21, which is convenient to operate and improves the feeding efficiency.

[0033] Further, as shown in Figure 3 The storage assembly 10 comprises a storage unit 11, a lifting unit 12 and a conveying unit 13. The storage unit 11 is used for storing balls. The lifting unit 12 is arranged in the storage unit 11. The storage unit 11 can store a large number of balls, and the lifting unit 12 can convey the balls at the bottom of the storage unit 11 upward. The conveying unit 13 guides the lifted balls to the set output port, ensuring the continuity of feeding.

[0034] The first feeding state also includes the lifting unit 12 moving the balls in the storage unit 11 to the conveying unit 13. The lifting unit 12 moves the balls to the conveying unit 13 in the first feeding state, providing a material source for the balls to enter the channel of the counting component 20, ensuring the smooth progress of the first feeding process.

[0035] Further, if Figure 5 As shown, the conveying unit 13 includes a conveying pipe 131, a detection hole 132, and a monitor 133. The conveying pipe 131 is connected to the storage unit 11, providing a conveying channel for the balls. The conveying pipe 131 is connected to the storage unit 11, and the end of the conveying pipe 131 away from the storage unit 11 is a set output port. The detection hole 132 passes through the outer circumference of one side of the conveying pipe 131 to the outer circumference of the other side of the conveying pipe 131. The monitoring ray emitted by the monitor 133 enters the conveying pipe 131 through the detection hole 132. The minimum angle between the monitoring ray and the central axis of the conveying pipe 131 on the side of the detection hole 132 is within a set range. The detection hole 132 passes through both sides of the conveying pipe 131, providing a passage for the monitoring ray. The monitoring ray enters the conveying pipe 131 to detect the balls in the pipe. The setting range can be 40°~80°. Setting the angle range between the monitoring ray and the central axis of the conveying tube 131 can avoid the ray being aimed only at the abutment of two adjacent balls (the small area of ​​this area can easily lead to misjudgment of detection), thereby improving the accuracy of monitoring and ensuring effective judgment of the presence of balls.

[0036] The first feeding state also includes the lifting unit 12 moving the balls in the storage unit 11 into the conveying pipe 131. When the balls move along the feeding direction in the conveying pipe 131, they pass through the monitoring rays. When the balls pass through the monitoring rays, the monitor 133 can detect whether there are balls in the conveying pipe 131, thereby judging whether there are sufficient balls in the storage unit 11 or whether the lifting unit 12 is abnormal, so as to facilitate timely discovery and handling of feeding problems.

[0037] Furthermore, the storage unit 11 includes a storage box 111, an inlet 112, and an outlet 113. The storage box 111 is used to store balls and provides storage space for the balls. The inlet 112 and the outlet 113 extend from the outer circumferential wall of the storage box 111 to the inner circumferential wall of the storage box 111. The inlet 112 and the outlet 113 are spaced apart. The balls move into the storage box 111 through the inlet 112. The lifting unit 12 is disposed within the storage box 111 and can efficiently transport the balls to the outlet 113.

[0038] The first feeding state also includes the lifting unit 12 moving the balls in the storage box 111 to the conveying unit 13 through the discharge port 113, providing a material source for the balls to enter the channel of the counting component 20, ensuring the smooth progress of the first feeding process.

[0039] Further, the lifting unit 12 comprises a first driving part 121 and a lifting part 122. The lifting part 122 is arranged in the storage unit 11. The lifting part 122 is in sliding connection with the storage unit 11. The first driving part 121 is in driving connection with the lifting part 122. The feeding state further comprises that the first driving part 121 drives the lifting part 122 to move from the standby state to the state that the balls move from the lifting part 122 to the conveying unit 13. The standby state comprises that the top end of the lifting part 122 is lower than the bottom end of the balls.

[0040] Further, the ball feeding mechanism further comprises a collecting bucket 24. The collecting bucket 24 can centrally receive the balls discharged from the second end of the first channel 222, avoid the balls from scattering, and facilitate subsequent processing of the balls.

[0041] The first discharging state further comprises that the balls enter the collecting bucket 24 through the second end. After entering the collecting bucket 24, the balls can be orderly gathered, preventing the balls from being damaged or lost due to disorderly scattering, and improving the efficiency of ball collection.

[0042] Further, the ball feeding mechanism further comprises a screening assembly 30. The screening assembly 30 is used for screening the diameter of the balls. The screening assembly 30 can detect the diameter of the balls, remove oversized or undersized balls that do not meet the specifications, and ensure that the size of the feeding balls meets the bearing assembly requirements.

[0043] The first discharging state further comprises that the balls move to the screening assembly 30 after passing through the collecting bucket 24. After passing through the collecting bucket 24, the balls enter the screening assembly 30, which can complete the screening of the balls in the feeding process, ensure that the balls entering the next step are qualified, and improve the precision of bearing assembly.

[0044] Embodiment two: The embodiment discloses a ball feeding method. The ball feeding method comprises steps S10-S30, and the steps are described in detail as follows. In step S10, based on a feeding instruction trigger, the balls in the storage assembly 10 move to the first channel 222 through the set output port of the storage assembly 10.

[0045] In step S20, based on that the first channel 222 is full of balls, the first driving part 121 drives the counting body 221 to move to the first discharging state. The first discharging state comprises that the first driving part 121 drives the counting body 221 to move, so that the set output port is disconnected from the first end. The balls in the first channel 222 move out of the first channel 222 through the second end. After the first channel 222 is full of balls, the first driving part 121 is triggered to move, so that the counting body 221 is switched to the first discharging state. The set output port is disconnected from the first end, which can avoid new balls from entering, and ensure the accuracy of the number of output balls.

[0046] In step S30, based on that the number of balls in the first channel 222 is 0, the feeding is completed.

[0047] It is understood by those of ordinary skill in the art that the above embodiments are specific cases for implementing the present disclosure, and in actual applications, various changes can be made in form and details without departing from the scope of the present disclosure.
