Description

Technical Field

[0001] This utility model relates to the field of automated production technology, and specifically to a double spring guide rail damper assembly machine. Background Technology

[0002] Drawer slide dampers are important functional components primarily used to prevent impacts and noise when drawers close, thereby improving the user experience. Drawer dampers protect the structural integrity of furniture and drawers by slowing down the closing speed, while achieving quieter and smoother operation. Their basic components include a damper and a spring: the damper consists of a cylinder, piston, and piston rod, which adjusts the resistance of the slider's movement via hydraulic or pneumatic pressure to achieve the buffering effect; the spring provides the return force, ensuring the slider returns to its original position after operation. This type of damper effectively avoids the noise and furniture damage problems caused by direct impact in traditional designs, making it a key component in modern high-end furniture and office equipment.

[0003] For example, a guide rail damper, patented in Chinese Patent Publication No. CN 201612346, includes a bracket, a damper, a spring, a slider, and a return block. The bracket has a damper housing space and a spring housing space. The damper includes a hydraulic cylinder, a piston, and a piston rod, with the hydraulic cylinder located within the damper housing space. The spring is located within the spring housing space, with one end connected to the bracket and the other end connected to the slider. The slider has a fork that engages with the return block. However, traditional dampers are assembled manually, which is inefficient, labor-intensive, and significantly increases production costs. Furthermore, with the continuous improvement of living standards, the demand for modern high-end furniture and office equipment is increasing, making traditional manual assembly insufficient to meet societal needs.

The rotary positioning mechanism 1 is provided with multiple uniformly circumferentially arranged fixtures 11 that are radially divergent. The bracket assembly mechanism 2 is used to place the bracket into the fixtures 11, and the rear slider assembly mechanism 3, the front slider assembly mechanism 4, the damping tube assembly mechanism 5, the first spring assembly mechanism 6, and the second spring assembly mechanism 8 are used to sequentially assemble the rear slider, the front slider, the damping tube, the first spring, and the second spring onto the bracket. A rotary positioning mechanism 1 drives the fixture 11 to continuously cycle and switch workstations. A support assembly mechanism 2 loads the support onto the fixture 11. As the rotary positioning mechanism 1 continuously switches workstations, the rear slider, front slider, damping tube, first spring, and second spring are sequentially assembled onto the support via a rear slider assembly mechanism 3, a front slider assembly mechanism 4, a damping tube assembly mechanism 5, a first spring assembly mechanism 6, and a second spring assembly mechanism 8, respectively. The assembled finished product is then delivered via a finished product discharge mechanism 7. This replaces manual assembly, significantly improving production efficiency, reducing labor costs, and lowering production costs. Furthermore, by distributing the fixture 11 outwards from the center of the rotary positioning mechanism 1, not only is it convenient for loading and assembling parts, but it also reduces the need for reversing and adjustment mechanisms, resulting in a simpler structure and lower costs.

[0027] The first spring assembly mechanism 6 includes a second vibratory plate 61 for automatically feeding out the first spring, a second material distribution device 62 disposed beside the second vibratory plate 61 for separating the first springs one by one, and a spring assembly robot 64 disposed between the second material distribution device 62 and the rotary transfer mechanism 1 for gripping the first springs and assembling them onto the bracket. The spring assembly robot 64 is provided with a fifth gripper device 65 and a sixth gripper device 66 for gripping the two ends of the first spring respectively. The second spring assembly mechanism 8 has the same structure as the first spring assembly mechanism 6.

[0028] The spring assembly robot 64 includes a second axis moving module 641 disposed between the second material dispensing device 62 and the rotary transfer mechanism 1, a third axis moving module 642 disposed on the second axis moving module 641, and a motor pulley assembly 643 disposed on the third axis moving module 642 for driving the relative movement of the fifth gripper device 65 and the sixth gripper device 66. The third axis moving module 642 is provided with a second slide rail 644 for the fifth gripper device 65 and the sixth gripper device 66 to slide.

[0029] The second slide rail 644 is provided with a first sliding seat 645 and a second sliding seat 646 that respectively support the movement of the fifth gripper device 65 and the sixth gripper device 66, and the first sliding seat 645 and the second sliding seat 646 are respectively connected to both sides of the belt in the motor pulley assembly 643.

[0030] In summary, during operation, the bracket is manually placed onto the conveying module 21, and a number of sliders, damping tubes, and springs are respectively placed into the first vibrating plate 31, the storage bin 511, and the second vibrating plate 61. Similarly, a number of front sliders are placed into the first vibrating plate 31 of the front slider assembly mechanism 4. Further, the first axis moving module 22 in the bracket assembly mechanism 2 drives the bracket picking gripper 23 and the oiling device 24 to move synchronously above the conveying module 21. Lubricating oil is applied to the mounting groove on the bracket by the oiling device 24, and then the bracket picking gripper 23 grabs the bracket, and the first axis moving module 22 drives the bracket to pick up the material. The material clamp 23 and the oiling device 24 drive the bracket to be transferred and installed onto the fixture 11 of the rotary transfer mechanism 1. Of course, according to actual needs, the bracket can also be transferred from the conveying module 21 to the fixture 11 first, and then the oiling device 24 applies lubricating oil to the bracket. Furthermore, as the rotary transfer mechanism 1 rotates continuously, the fixture 11 is switched to different workstations in sequence. When the number of fixtures 11 is equal to the number of workstations, it can be ensured that there is one fixture 11 at each workstation after each transfer. In this embodiment, the number of fixtures 11 is eight. Furthermore, when the fixture 11 carrying the bracket is transferred to the rear slider assembly mechanism 3, the first The vibratory feeder 31 has already arranged and sent the rear sliders to the first material distribution device 33. The first material distribution device 33 then separates the rear sliders one by one, and the rear slider assembly robot 34 picks up the rear sliders and installs them into the bracket. Because the fixtures are radially distributed along the rotary transfer mechanism 1, the rear slider assembly robot 34 does not need to change direction after picking up the rear sliders and can directly move and install them into the fixture 11. Furthermore, when the fixture 11 carrying the bracket is transferred to the front slider assembly mechanism 4, the front slider assembly mechanism 4 installs the front slider onto the bracket, and one end of the front slider is pressed and fastened to the rear slider. Further, when the fixture 11 carrying the bracket is transferred to the damping tube assembly... When the damping tubes are installed at the 5th position, the damping tube feeding device 51 sends the damping tubes one by one to the second detection device 52 for orientation detection. Then, the transfer and adjustment robot 55 picks up the damping tubes from the second detection device 52 and transfers them to the prepositioning device 54. During the transfer process, the transfer and adjustment robot 55 adjusts the orientation of the damping tubes appropriately according to the detection results of the second detection device 52. Then, the prepositioning device 54 tilts the damping tubes and clamps and pulls out the plugs of the damping tubes to complete the prepositioning of the damping tubes, so as to facilitate the fastening of the damping tubes. Then, the damping tube assembly robot 53 picks up the damping tubes from the prepositioning device 54 and fastens them to the bracket.Furthermore, when the fixture 11 carrying the support is transferred to the first spring assembly mechanism 6, the second vibratory feeder 61 has already arranged and sent the first springs to the second material distribution device 62. Subsequently, the second material distribution device 62 separates the first springs one by one in a staggered manner, and the spring assembly robot 64 moves the fifth gripper device 65 and the sixth gripper device 66 above the second material distribution device 62 to clamp the two ends of the first spring. Then, the motor pulley assembly 643 drives the fifth gripper device 65 and the sixth gripper device 66 to pull the first spring apart. After the spring assembly robot 64 drives the fifth gripper device 65 and the sixth gripper device 66 to pull apart, the first spring is pulled apart. After the claw device 66 moves onto the fixture 11, it hooks the two ends of the first spring onto the bracket and the rear slider respectively, thus completing the assembly of the first spring. Further, when the fixture 11 carrying the bracket is transferred to the second spring assembly mechanism 8, the second spring assembly mechanism 8 installs the second spring onto the fixture 11. Further still, when the rotary positioning mechanism 1 moves the assembled damper assembly to the finished product unloading mechanism 7, the finished product unloading mechanism 7 removes the damper assembly from the fixture 11. Then, the unloaded fixture 11 continues to be rotated to the bracket assembly mechanism 2 for the next round of assembly.

[0031] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model.
