[0002] The slider consists of an end cap, a slider body, and a retainer. A ball receiving groove is formed inside the slider. The ball receiving groove includes two symmetrical sets of spiral grooves, which are arranged on both sides of the slider. The spiral grooves are filled with steel balls and are enclosed by the end cap, the slider body, and the retainer. When assembling steel balls, multiple steel balls need to be filled into the ball receiving grooves in sequence. In the prior art, the assembly of steel balls is done manually, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] This utility model solves the problems in related technologies and proposes a ball assembly mechanism with a slider. The slider slides in conjunction with the ball blowing guide rail. The ball enters from the feeding channel of the ball blowing guide rail and exits from the discharge port. Then it enters the ball receiving groove corresponding to the discharge port, thereby realizing the automatic assembly of the ball and improving the assembly efficiency.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a ball assembly mechanism for a slider, including a ball blowing guide rail for slidingly engaging the slider, the side of the ball blowing guide rail having a discharge port corresponding to the ball receiving groove on the slider, and the ball blowing guide rail having a feeding channel connected to the discharge port.

[0005] As a preferred embodiment, the system also includes a vibration assembly, which comprises a linear drive assembly and a vibrating plate, wherein the linear drive assembly drives the slider to vibrate via the vibrating plate.

[0006] As a preferred embodiment, the linear drive assembly is located at the bottom of the ball bearing guide rail, the vibrating plate is a U-shaped plate, and the vibrating plate drives the two sides of the slider to vibrate.

[0007] As a preferred embodiment, the system also includes a buffer guide rail, which has a buffer channel communicating with the feeding channel. The center lines of the feeding channel and the buffer channel are on a straight line, and the buffer channel is connected to the feeding module.

[0008] As a preferred embodiment, the system also includes a blocking assembly located between the buffer guide rail and the ball-blowing guide rail. The blocking assembly includes a blocking cylinder and a blocking plate, which is slidably fitted between the buffer guide rail and the ball-blowing guide rail to disconnect or connect the buffer channel and the feeding channel.

[0009] As a preferred embodiment, the baffle plate has a through hole for the steel ball to pass through, and the buffer channel and the feeding channel are connected through the through hole.

[0010] As a preferred embodiment, the system also includes a transplanting component located on one side of the ball guide rail and / or the buffer rail, for driving the slider to move along the direction of the ball's movement.

[0011] As a preferred embodiment, the transplanting assembly includes grippers and a moving carrier, wherein the moving carrier drives the grippers to move.

[0012] As a preferred embodiment, the system also includes a transfer guide rail, which is connected to the ball bearing guide rail, and the slider slides onto the transfer guide rail after being fitted with steel balls.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) When this utility model is assembled, the slider slides in conjunction with the ball blowing guide rail. The steel ball enters from the feeding channel of the ball blowing guide rail and exits from the discharge port. Then it enters the steel ball receiving groove corresponding to the discharge port, thereby realizing the automatic assembly of the steel ball and improving the assembly efficiency. (2) A vibration component is also provided at the bottom of the ball guide rail. The vibration plate is driven to move up and down reciprocally by the linear drive component so that the sides of the slider vibrate, thereby causing the steel ball assembled in the ball receiving groove to vibrate as well, thus avoiding the steel ball from getting stuck. (3) A buffer rail is set between the ball blowing guide rail and the air blowing module. It can not only place the slider to be assembled, but also buffer some steel balls. In the subsequent assembly process, there is no need to frequently obtain sliders and steel balls from the outside, which reduces the assembly waiting time and thus significantly improves the assembly efficiency. (4) A blocking component is set between the ball blowing guide and the buffer guide. According to the demand for the number of steel balls and the assembly rhythm during the assembly process, the component can flexibly switch the working mode to selectively block or release the incoming steel balls, thereby effectively avoiding the accumulation of steel balls in the ball blowing guide caused by excessive incoming material or excessive flow rate, and ensuring the stable operation of the assembly system. (5) By moving the carrier to move the gripper, the slider can be transferred from the buffer guide rail to the ball guide rail. When the slider vibrates, the gripper can also block the slider to prevent it from falling off the ball guide rail. In addition, after filling, the transfer component moves left and right, which drives the slider to move left and right so that the steel ball can roll smoothly inside the slider.

[0022] See Figure 8 In this embodiment, the slider 7 is composed of an end cap 71, a slider body 72, and a retainer 73. A ball receiving groove is formed inside the slider 7. The ball receiving groove includes two sets of symmetrical spiral grooves, which are arranged on both sides of the slider 7. The spiral grooves contain steel balls. The spiral grooves are enclosed by the end cap 71, the slider body 72, and the retainer 73. Specifically, a portion of the spiral groove is formed on both sides of the slider body 72, that is, the two ends and the inner side of the spiral groove are missing. The two ends of the spiral groove are enclosed by the end cap 71, and the inner side of the spiral groove is enclosed by the retainer 73, thereby forming a complete spiral groove.

[0023] like Figures 1 to 7 As shown, this embodiment provides a ball bearing assembly mechanism for a slider, including a ball bearing guide rail 1 for slidingly engaging a slider 7. The side of the ball bearing guide rail 1 has a discharge port 11 corresponding to the ball bearing receiving groove on the slider 7. The ball bearing guide rail 1 has a feeding channel 12 connected to the discharge port 11. During assembly, the slider 7 is slidably engaged above the ball bearing guide rail 1, with the ball bearing receiving groove on the slider 7 aligned with the discharge port 11 on the ball bearing guide rail 1. The ball bearing enters the ball bearing guide rail 1 from the feeding port 13, passes through the feeding channel 12, and finally exits from the discharge port 11, entering the ball bearing receiving groove on the slider 7 corresponding to the discharge port 11. This achieves automatic ball bearing assembly and improves assembly efficiency.

[0024] In one embodiment, the ball assembly mechanism of the slider further includes a vibration component 4, which includes a linear drive component 41 and a vibrating plate 42. The linear drive component 41 can be a cylinder. The linear drive component 41 drives the vibrating plate 42 to reciprocate, thereby driving the slider 7 to vibrate. This vibration method enables the ball to oscillate slightly in the ball receiving groove, ensuring that the ball can be assembled accurately and smoothly, effectively avoiding jamming problems caused by friction, interference and other factors during the assembly process, thereby improving the reliability and stability of the entire assembly system.

[0025] To accommodate the vibration component 4, the ball bearing guide 1 is designed as an I-shaped guide. The concave surface of the ball bearing guide 1 does not completely fit the inner wall of the slider 7, but rather leaves a certain gap so that the slider 7 can move up and down.

[0026] In one embodiment, the linear drive assembly 41 is located at the bottom of the ball bearing guide rail 1, and the vibrating plate 42 is a U-shaped plate that extends or retracts from the clearance opening on the bottom plate 6, thereby driving the two sides of the slider 7 to vibrate.

[0027] In one embodiment, the ball assembly mechanism of the slider also includes a buffer guide rail 2. The buffer guide rail 2 can be used to temporarily store a portion of the balls, and the slider 7 to be assembled can also be slidably fitted onto the buffer guide rail 2. After the slider 7 located on the ball blowing guide rail 1 is assembled, the slider 7 to be assembled on the buffer guide rail 2 can be moved to the ball blowing guide rail 1 for ball assembly, reducing assembly waiting time and thus significantly improving assembly efficiency. The buffer guide rail 2 has a buffer channel 21 connected to the feeding channel 12. The center lines of the feeding channel 12 and the buffer channel 21 are on a straight line. This coaxial layout design greatly reduces the resistance when the balls are transferred between channels, effectively improving the reliability and efficiency of ball conveying. The buffer channel 21 is connected to the feeding module, ensuring that the feeding process can continuously and stably replenish the buffer channel 21 with balls.

[0028] In one embodiment, the feeding module includes a steel ball hopper and an air pump. The steel ball hopper is connected to the buffer channel 21 via a pipe, and the pipe is connected to the air pump via a branch pipe. When a predetermined number of steel balls enter the pipe, the air pump is used to press the steel balls into the buffer channel 21.

[0029] In one embodiment, the ball assembly mechanism of the slider further includes a blocking component 5 located between the buffer guide rail 2 and the ball blowing guide rail 1. The blocking component 5 includes a blocking cylinder 51 and a blocking plate 52. The blocking plate 52 is slidably engaged between the buffer guide rail 2 and the ball blowing guide rail 1 to disconnect or connect the buffer channel 21 and the feeding channel 12. Specifically, the blocking plate 52 has a through hole 53 for the ball to pass through, and the buffer channel 21 and the feeding channel 12 are connected through the through hole 53.

[0030] After the steel balls blown into the ball guide rail 1 are assembled, the blocking cylinder 51 drives the blocking plate 52 to extend upward, so that the through hole 53 is not connected with the buffer channel 21 and the feeding channel 12. Thus, the steel balls in the buffer channel 21 cannot enter the feeding channel 12. When the steel balls need to be fed into the ball guide rail 1 for assembly, the blocking cylinder 51 drives the blocking plate 52 to retract downward, so that the through hole 53 is connected with the buffer channel 21 and the feeding channel 12, and the steel balls can be fed and assembled. The blocking component 5 can flexibly switch working modes according to the number of steel balls required during the assembly process and the assembly rhythm, selectively blocking or releasing the incoming steel balls, thereby effectively avoiding the accumulation of steel balls in the ball guide rail 1 caused by excessive incoming material or excessive flow rate, and ensuring the stable operation of the assembly system.

[0031] In one embodiment, the ball assembly mechanism of the slider further includes a transfer component 3, which is located on one side of the ball blowing guide rail 1 and / or the buffer guide rail 2, and is used to drive the slider 7 to move along the ball walking direction. Specifically, the transfer component 3 includes a gripper 31 and a moving carrier 32. The moving carrier 32 can be a linear module, and the gripper 31 can be a pneumatic gripper. The moving carrier 32 drives the gripper 31 to move, thereby transferring the slider 7 from the buffer guide rail 2 to the ball blowing guide rail 1. In addition, when the slider 7 vibrates, the gripper 31 can also block the slider 7 to prevent the slider 7 from falling off the ball blowing guide rail 1.

[0032] In one embodiment, a transfer guide 8 is also included, which is connected to the ball bearing guide 1. After the slider 7 is equipped with steel balls, it is driven to the transfer guide 8 by the transfer assembly 3 to prepare for the next process (marking or installing the retainer 73).

[0033] In this embodiment, the installation sequence of the slider is as follows: first, end caps 71 are installed at both ends of the slider 7; then, the ball bearing assembly mechanism of the slider is fed in to assemble the ball bearings; and finally, the retainer 73 is installed. The working process of the ball bearing assembly mechanism of the slider in this embodiment is as follows: In the initial state, the blocking cylinder 51 drives the blocking plate 52 to extend upward, so that the through hole 53 is not connected to the buffer channel 21 and the feeding channel 12. The feeding module presses a predetermined number of steel balls into the buffer channel 21. At the same time, the robot or manual places the slider 7 on the buffer guide rail 2, waiting for filling.

[0034] Before the filling operation begins, the transfer assembly 3 moves the slider 7 onto the ball-blowing guide rail 1, aligning the outlet 11 of the ball-blowing guide rail 1 with the ball-receiving groove on the slider 7. It should be noted that the outlet 11 only needs to align with the ball-receiving groove on the slider 7; the slider 7 can be positioned at the front, middle, or rear of the outlet 11 for ball blowing without restriction. After the slider 7 is in place, the blocking cylinder 51 drives the blocking plate 52 to retract downwards, connecting the buffer channel 21 and the feeding channel 12. The air pump then drives the ball-receiving material through the feeding channel 12 and the outlet 11 into the ball-receiving groove of the slider 7.

[0035] To prevent the steel balls from getting stuck, during the filling process, the linear drive assembly 41 drives the vibrating plate 42 to reciprocate, thereby driving the slider 7 to vibrate and preventing the steel balls from getting stuck.

[0036] After loading is complete, the transfer assembly 3 moves left and right, causing the slider 7 to move left and right, allowing the steel balls to roll smoothly within the slider 7. After the shaking is complete, the transfer assembly 3 moves the slider 7 to the transfer guide rail and then proceeds to the next station for marking or installation of the retainer.

[0037] The blocking cylinder 51 drives the blocking plate 52 to extend upward, waiting for the feeding module to press the steel ball into the buffer channel 21, and then enter the next cycle.

[0038] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
