[0023] Example 1 See also Figure 1-4 , an automatic assembly equipment for automobile shock absorbers, including an assembly table 1, an end cap conveyor belt 2 is arranged on one side of the assembly table 1, a clamping conveyor belt 3 and a material discharge conveyor belt 4 are arranged on the other side of the assembly table 1, the clamping conveyor belt 3 is used to convey a damper with a compression spring, and the material discharge conveyor belt 4 is used to convey the assembled shock absorber, and an intelligent manipulator 5 is arranged on one side of the clamping conveyor belt 3 and the material discharge conveyor belt 4, and the intelligent manipulator 5 is used to clamp the damper with a compression spring and the assembled shock absorber, and the end cap conveyor belt 2, the clamping conveyor belt 3 and the material discharge conveyor belt 4 work together to achieve continuous supply of parts and timely output of finished products. The end cap conveyor belt 2 can continuously provide end caps, the clamping conveyor belt 3 can stably convey the damper with a compression spring, and the intelligent manipulator 5 quickly clamps and transfers automobile shock absorber parts between different conveyor belts and the assembly table 1, which greatly reduces the material handling time during the assembly process.

[0024] An assembly groove 6 is provided on the assembly table 1, and the assembly groove 6 and the end cover conveyor belt 2 are on the same axis. An assembly clamping and fixing mechanism 7 is provided in the assembly groove 6. A moving mechanism 8 is installed on the top of the assembly table 1 through a bracket. A screw clamping mechanism 9 is provided on the moving mechanism 8 corresponding to the assembly groove 6. The screw clamping mechanism 9 is used to clamp and assemble the end cover on the rotating end cover conveyor belt 2. The intelligent manipulator 5 includes an intelligent base 51, a manipulator arm 52 and a gripping mechanism 53. The gripping mechanism 53 is used to place the damper with a compression spring in the assembly groove 6 and press the compression spring downward.

[0025] During assembly, the intelligent manipulator 5 first places the damper with a compression spring on the clamping conveyor belt 3 into the assembly groove 6, and the lower part of the damper is clamped and fixed by the assembly clamping and fixing mechanism 7, and then the compression spring on the auxiliary lowering damper is pressed down by the clamping mechanism 53 to avoid affecting the assembly of the end cover; then the rotating clamp mechanism 9 is moved to the corresponding end cover conveyor belt through the moving mechanism 8, and an end cover is clamped and then corresponds to the damper, and the end cover is assembled on the damper under the action of the rotating clamp mechanism 9. After the assembly is completed, the intelligent manipulator 5 clamps the assembled shock absorber to the unloading conveyor belt 4 and sends it to the next process. The whole process does not require manual intervention, which greatly improves the assembly speed and can meet the assembly requirements of shock absorbers in large-scale automobile production.

[0026] Working principle of automobile shock absorber automatic assembly equipment: 1. Parts supply: The end cap conveyor belt 2 runs continuously, and the clamp conveyor belt 3 stably conveys the damper with compression spring, providing the necessary parts for assembly; 2. Damper placement: The intelligent base 51 of the intelligent manipulator 5 controls the movement of the manipulator 52, and the manipulator 52 drives the clamping mechanism 53 to clamp the damper with a compression spring on the clamping conveyor belt 3 and place it in the assembly slot 6 of the assembly table 1; 3. Fixing the damper and pressing down the compression spring: The assembly clamping and fixing mechanism 7 in the assembly groove 6 clamps and fixes the lower part of the damper placed in the assembly groove 6 to prevent displacement during the subsequent assembly process. At the same time, the clamping mechanism 53 assists in pressing down the compression spring on the damper to make room for the assembly of the end cover and prevent the compression spring from hindering the assembly of the end cover; 4. End cap clamping: The moving mechanism 8 on the top bracket of the assembly table 1 drives the clamping mechanism 9 to move to the position corresponding to the end cap conveyor belt 2, and the clamping mechanism 9 accurately clamps the end cap on the end cap conveyor belt 2; 5. End cover assembly: The moving mechanism 8 then moves the clamping mechanism 9 that has clamped the end cover to a position corresponding to the damper in the assembly groove 6. The clamping mechanism 9 assembles the end cover to the damper through its own rotation and downward pressing, thus completing the key assembly steps of the shock absorber; 6. Finished product clamping: The clamping mechanism 53 of the intelligent manipulator 5 moves again to clamp the assembled shock absorber from the assembly slot 6; 7. Finished product transportation: The gripping mechanism 53 places the assembled shock absorber on the unloading conveyor belt 4, and the unloading conveyor belt 4 transports the assembled shock absorber to the next production link or storage area.

[0027] like Figure 3 As shown, the gripping mechanism 53 includes a hydraulic cylinder 531, which is fixedly mounted on the end of the mechanical arm 52, and a U-shaped block 532 is fixedly connected to the cylinder rod end of the hydraulic cylinder 531, and a servo motor 533 is fixedly mounted on the outside of the U-shaped block 532. Two arc-shaped clamping blocks 534 are arranged on the inside of the U-shaped block 532, and threaded rods 535 threadedly connected thereto are inserted through the two arc-shaped clamping blocks 534, one end of the threaded rod 535 is fixedly connected to the output shaft of the servo motor 533, and the other end of the threaded rod 535 is rotatably connected to the inner wall of the U-shaped block 532, and a limit rod 536 slidably connected thereto is inserted through the two arc-shaped clamping blocks 534, and the two ends of the limit rod 536 are respectively fixedly connected to the inner wall of the U-shaped block 532. When it is necessary to clamp an object, the hydraulic cylinder 531 first pushes the U-shaped block 532 to a suitable position. Then the servo motor 533 is started to drive the threaded rod 535 to rotate. Since the threaded rod 535 is threadedly connected to the arc clamping block 534, and the arc clamping block 534 is limited by the limit rod 536 to only move in a straight line, the two arc clamping blocks 534 will be relatively close to or away from each other, thereby clamping or releasing the object. The arc clamping block 534 adopts this threaded connection and movement mode to make its movement precision higher.

[0028] like Figure 2 As shown, the assembly clamping and fixing mechanism 7 includes two electric telescopic rods 71 ​​symmetrically fixedly installed on both sides of the inner wall of the assembly groove 6, and the opposite ends of the two electric telescopic rods 71 ​​are fixedly connected with assembly clamps 72. Among them, an infrared sensor 11 is provided in the assembly groove 6. When the damper is placed in the assembly groove 6, the infrared sensor 11 detects the existence of the damper, and then the control system drives the two electric telescopic rods 71 ​​to extend, so that the two assembly clamps 72 move toward the middle until the lower part of the damper is clamped and fixed. After the assembly is completed, the electric telescopic rod 71 contracts and releases the clamping of the damper. The infrared sensor 11 arranged in the assembly groove 6 can monitor in real time whether there is a damper in the assembly groove 6, provide feedback information for automatic control, and further improve the accuracy and efficiency of assembly.

[0029] like Figure 2As shown, the moving mechanism 8 includes a moving slot block 85, a slider 82 is slidably connected in the moving slot block 85, a hydraulic cylinder 91 is fixedly connected to the slider 82, a moving motor 83 is fixedly installed on the outer side of the moving slot block 85, a screw rod 84 is threadedly connected to the slider 82, and the screw rod 84 is fixedly connected to the output shaft of the moving motor 83. When it is necessary to move the rotating clamp mechanism 9, the moving motor 83 is started to drive the screw rod 84 to rotate. The rotation of the screw rod 84 causes the slider 82 to move in the moving slot block 85 along the direction of the screw rod 84, thereby driving the rotating clamp mechanism 9 fixedly connected to the slider 82 to move to the target position.

[0030] like Figure 2 , 4 As shown, the clamping mechanism 9 includes a hydraulic cylinder 91, which is mounted on a moving mechanism 8. The moving mechanism 8 drives the hydraulic cylinder 91 to reciprocate laterally. A rotary motor 92 is mounted at the bottom of the hydraulic cylinder 91. The output shaft of the rotary motor 92 is fixedly connected to a connecting plate 93. A receiving groove 94 is provided at the bottom of the connecting plate 93. A plurality of clamping blocks 95 are arranged in a circular array on the outside of the receiving groove 94. The outside of each clamping block 95 is fixedly connected to an electric telescopic rod 96, which is fixedly mounted on the connecting plate 93. First, the hydraulic cylinder 91 lowers the clamping mechanism 9 to a suitable height so that the clamping block 95 can clamp the end cap on the end cap conveyor belt 2. The electric telescopic rod 96 is extended to drive the clamping block 95 to clamp the end cap. Then, the moving mechanism 8 moves the clamping mechanism 9 with the end cap clamped to a position corresponding to the damper in the assembly groove 6.

[0031] Next, the hydraulic cylinder 91 is lowered again to assemble the end cover onto the damper, and the rotary motor 92 is started to rotate the end cover thread onto the damper. After the assembly is completed, the electric telescopic rod 96 is retracted to release the clamping of the end cover.

[0032] In addition, the end cap conveyor belt 2 is symmetrically mounted with guide rods 10 through bolts, and rollers are arranged on the guide rods 10, and the two guide rods 10 are in an "eight" shape. This structure can guide the conveying of the end cap, so that the end cap maintains a stable posture and direction during the conveying process, and prevents the end cap from deflecting or rolling on the conveyor belt, thereby ensuring that the clamping mechanism 9 can accurately clamp the end cap. Among them, the arc clamping block 534, the assembly clamping block 72 and the clamping block 95 are all provided with an anti-slip layer.

[0033] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
