Description

Technical Field

[0001] This utility model relates to the field of automated assembly, specifically to an automatic assembly machine for slide rail production. Background Technology

[0002] The bead nest is a core component of a slide rail. It consists of rolling balls mounted on a support frame, which cause sliding between two slide rails, thus opening and closing the slide rail. Therefore, it is widely used in various two-section, three-section, or concealed slide rails. With the continuous improvement of automation in slide rail manufacturing, the automation level of bead nest assembly is also increasing. For example, Chinese patent document CN212636644U discloses a bead nest feeding mechanism for an automatic bead loading machine. This mechanism uses a feeding sloping plate for conveying materials and utilizes the linkage of a second pneumatic telescopic rod, a first connecting rod, and a third connecting rod to achieve automatic material feeding and discharging.

[0003] While the aforementioned feeding mechanism automates bead assembly to some extent, it still suffers from the following technical drawbacks: First, because the bead socket requires the assembly of several steel balls to achieve rolling contact with the slide rail, incomplete assembly is easily possible due to dimensional tolerances, significantly impacting the normal operation of the bead socket on the slide rail. Second, the feeding mechanism is only suitable for assembling bead sockets of the same model. In reality, different models of slide rails use bead sockets with varying lengths, steel ball sizes, and assembly positions. Therefore, this feeding mechanism cannot adapt to the assembly of bead sockets of different models and sizes, limiting its applicability. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an automatic assembly machine for slide rails with strong assembly stability and applicable to the production of different models of bead nests.

[0005] This utility model provides an automatic bead assembly machine for slide rail production, which mainly includes a frame, a bead conveying mechanism, a material sorting mechanism, an assembly mechanism, and a testing mechanism. The bead conveying mechanism and the material sorting mechanism are sequentially fixed to the frame and connected together. At least one assembly mechanism is provided and is mounted on the frame. The assembly mechanism is located outside the bead conveying mechanism and corresponds to its conveying path position to assemble the beads passing through it. At least one testing mechanism is also provided and is mounted on the frame. The testing mechanism is also located outside the bead conveying mechanism and corresponds to its conveying path position. The assembly mechanism and the testing mechanism are sequentially arranged on the frame.

[0006] By optimizing the above structure, the bead conveying mechanism includes a feeding conveyor belt, a conveying channel, a conveying robot, and a conveying assembly. The feeding conveyor belt is located at the end of the frame to store and transport unassembled beads. The conveying channel is located on the frame, corresponding to the position of the feeding conveyor belt. The conveying robot is positioned between the feeding conveyor belt and the conveying channel, gripping the unassembled beads and placing them on the conveying channel. The conveying assembly is located below the frame and corresponds to the position of the conveying channel. The conveying assembly includes a conveying motor, a conveying support, a conveying plate, and a conveying lever. The conveying motor and the conveying support are both mounted on the frame; the conveying plate is located on the conveying support and can slide back and forth on the support. The conveying plate is fixedly connected to the output shaft of the conveying motor to drive the conveying plate to slide on the conveying support; the conveying lever is located on the conveying plate and corresponds to the position of the beads, so as to move the beads within the conveying channel when the conveying plate slides.

[0007] By further improving the above structure, a lifting cylinder is also provided between the conveying plate and the conveying block. The cylinder body of the lifting cylinder is fixedly connected to the conveying plate, and the piston rod of the lifting cylinder is fixedly connected to the conveying block, so as to prevent the bead nest from retreating in the conveying channel by the downward movement of the conveying block.

[0008] By optimizing the above structure, the discharge sorting mechanism includes a discharge conveyor belt, a discharge robot, a waste channel, and a sorting cylinder. The discharge conveyor belt is mounted on the frame to output the assembled bead nests. The sorting cylinder is mounted on the frame, and its piston rod is fixedly connected to the discharge robot. The stroke of the sorting cylinder corresponds to both the discharge conveyor belt and the waste channel. The discharge robot is positioned corresponding to both the bead nest conveying mechanism and the discharge conveyor belt to remove the assembled bead nests.

[0009] By further improving the above structure, the piston rod of the sorting cylinder also has a sorting baffle. The sorting baffle can switch between the discharge conveyor belt and the waste channel to realize the switching of the discharge robot's feeding between the discharge conveyor belt and the waste channel.

[0010] By optimizing the above structure, the assembly mechanism includes a vibratory feeder, an assembly channel, an assembly base, and a first assembly cylinder. The vibratory feeder is mounted on the frame to transport the bead nest components. The assembly channel is located between the vibratory feeder and the assembly base, corresponding to their respective positions. The assembly channel also has a pusher cylinder, located on the side of the assembly channel opposite to the assembly base, to push the bead nest components into the assembly base. The assembly base corresponds to the assembly channel, while the first assembly cylinder is located on the assembly base, and its piston rod can extend into the assembly base to complete the assembly of the bead nest components.

[0011] By further improving the above structure, the assembly base also includes a second assembly cylinder and a third assembly cylinder. The second assembly cylinder is located on the side of the assembly base opposite to the first assembly cylinder, while the third assembly cylinder is located on the side of the assembly base opposite to the assembly channel. The piston rods of both the second and third assembly cylinders can extend into the assembly base to complete the assembly of the bead nest components.

[0012] By optimizing the above structure, the detection mechanism includes a first detection head, a second detection head, and a third detection head. The first and second detection heads are respectively located on the outer sides of the bead nest conveying path, while the third detection head is located above the bead nest conveying path, and the first, second, and third detection heads all correspond to the positions of the bead nests.

[0013] The beneficial effects of the automatic bead-nesting assembly machine for slide rail production of this utility model are as follows:

[0014] 1. The automatic bead assembly machine for slide rail production of this utility model adopts continuous conveying, assembly, and inspection to achieve automatic bead assembly. First, the assembly machine uses staggered assembly and inspection mechanisms to perform real-time inspection of the bead assembly, so as to distinguish defective products generated in different assembly steps in a timely manner, eliminating the need for traditional manual screening or subsequent screening after assembly, and greatly improving the assembly efficiency of bead assembly. Second, the assembly machine of this utility model requires no manual intervention from material feeding to finished product output. In addition, when switching between different models and sizes of bead, only the assembly base needs to be changed, which has strong applicability and reliability.

[0015] 2. The automatic assembly machine for producing slide rails of this utility model adopts a multi-directional assembly and multi-directional inspection structure. This structure enables the assembly of different parts of the slide rail to be completed simultaneously at one assembly station or inspection station, greatly increasing the assembly and inspection efficiency of the slide rail.

In this embodiment, a horizontal conveying cylinder 209 and a vertical conveying cylinder 210 are also provided between the conveying robot 203 and the feeding conveyor belt 201. A transverse conveying cylinder 209 is fixed above the feeding conveyor belt 201, and its piston rod is fixed together with the cylinder body of the vertical conveying cylinder 210, which in turn is fixedly connected to the feeding robot. Through the cooperation of the transverse conveying cylinder 209 and the vertical conveying cylinder 210, the conveying robot 203 can move forward, backward, upward, and downward between the feeding conveyor belt 201 and the conveying channel 202, thereby improving the reliability and stability of the conveying robot 203.

The assembly seat 43 is also fixed on the frame 1. It is located outside the bead conveying mechanism 2 and corresponds to the position of the assembly channel 42, so as to form a stable assembly relationship with the balls or rollers in the assembly seat 43 when the bead passes through.
