Description

Technical Field

[0001] This invention belongs to the field of assembly equipment technology, and in particular relates to a fully automatic equipment for assembling end caps and torsion springs. Background Technology

[0002] The assembly of end caps and torsion springs is a typical component assembly process in the field of mechanical product manufacturing. Its core lies in achieving the product's preset functions through the precise cooperation of the two, while ensuring the stability, safety and service life of the whole machine. In automated production scenarios, automatic assembly equipment for end caps and torsion springs is widely used, such as the micro motor end cap torsion spring automatic assembly machine disclosed in patent announcement number CN119036018A.

[0003] In the existing technology, for automated assembly equipment of end caps and torsion springs, electric grippers are generally used to hold the torsion springs conveyed by the feeding tray and accurately install the torsion springs into the slots of the end caps. In order to ensure the stability of the torsion springs during the gripping and transfer process and to avoid assembly deviations caused by insufficient gripping force or slippage, the industry usually sets rubber pads on the gripping part of the electric grippers to increase the friction between the grippers and the torsion springs by utilizing the elastic properties of rubber materials. However, in actual mass production operations, the rubber pads of the electric gripper's clamping part will gradually develop wear problems such as surface scratches and local dents due to long-term friction with the surface of the torsion spring. The wear will directly reduce the friction between the gripper and the torsion spring, affecting the clamping stability of the torsion spring, which in turn leads to a decrease in assembly accuracy and an increase in product defect rate. At this time, the operator needs to stop the machine to replace the rubber pads, and the downtime maintenance will take up a long production time, which seriously affects the continuity of the assembly process and production efficiency. Furthermore, due to the small size of the torsion spring, its contact area with the rubber pad is limited. The wear of the rubber pad is often concentrated only in the local contact area. In this case, replacing the entire rubber pad would result in a serious waste of material in the unworn area, increasing the cost of production materials, which is contrary to the concept of efficient and energy-saving modern mechanical manufacturing.

[0004] To address this issue, a fully automated device for assembling end caps and torsion springs is proposed. Summary of the Invention

The pressure pipe 38 is equipped with a pressure relief valve 39 and a piston plate 30 is fixedly connected to it. The side wall of the top block 27 is provided with a pneumatic hole 31 that communicates with the pneumatic chamber 28.

A cleaning assembly 19, disposed on the side wall of the mounting frame 1, is used to clean residue from the surface of the torsion spring. The cleaning assembly 19 includes a collection box 191 and a cleaning pump 192 fixedly connected to the front side wall of the mounting frame 1. The air inlet of the cleaning pump 192 is connected to the lower side wall of the collection box 191. A filter element is located inside the collection box 191 at the air inlet of the cleaning pump 192. An exhaust pipe 20 is fixedly connected to the air outlet of the cleaning pump 192.

[0021] A semi-circular cover 32 is fixedly connected to the side wall of each of the two clamping parts 10 on opposite sides. The rubber pad 11 is located inside the semi-circular cover 32. A piston chamber 33 is opened inside the clamping part 10, and a piston block 34 is slidably arranged in the piston chamber 33. A moving pin 35 is fixedly connected to the side wall of the piston block 34 near the semi-circular cover 32. The end of the moving pin 35 away from the piston block 34 extends out of the piston chamber 33 and is connected to a compression plate 36. An air pressure channel 37 is opened between the piston chamber 33 and the air pressure chamber 28, which can protect other areas of the rubber pad 11.

[0022] The operating principle of this invention is explained as follows: The torsion spring feeding tray is placed on the rear side of the mounting frame 1, and the discharge end of the torsion spring feeding tray is located in the feeding port on the rear side of the mounting frame 1. The end caps produced on the production line are transported to the bottom of the mounting frame 1 by the conveyor belt 3. After the control cabinet 2 detects that the end cap has moved to the bottom of the rotating frame 15 through the second vision sensor 18, the control cabinet 2 will control the conveyor belt 3 to stop working. Then, the control cabinet 2 controls the lifting electric push rods 121 on both sides to work. The lifting electric push rods 121 on both sides will drive the second linear module 122 to move downward. The second linear module 122 will drive the sorting frame 13, the rotating frame 15 and the two arc plates 17 to move downward together to the set position. Then, the control cabinet 2 controls the horizontal electric push rods on both sides. 16. The horizontal electric push rod 16 drives the arc plate 17 to work through the pressure sensor. The two arc plates 17 clamp the end cover and apply a force of 20N between the end cover and the arc plate 17. Then, the control cabinet 2 uses the second vision sensor 18 to observe the placement angle of the torsion spring groove on the end cover, and drives the rotating frame 15 and the end cover to rotate through the sorting motor 14, so that the groove on the surface of the end cover is at the set angle. When the end cover on the conveyor belt 3 is shifted too much due to transportation vibration and is located outside the arc plates 17 on both sides, the control cabinet 2 will also control the second linear module 122 to work. The second linear module 122 drives the sorting frame 13 to move a certain distance in the horizontal direction, so that the end cover is located inside the two arc plates 17, which is convenient for subsequent sorting work. Next, control cabinet 2 controls the horizontal electric push rods 16 on both sides to move the arc plates 17 on both sides away from each other, so that the arc plates 17 and the end caps separate. Then, control cabinet 2 controls the two lifting electric push rods 121 to move the second linear module 122, the sorting frame 13 and the arc plates 17 upward together to the set height. Then, control cabinet 2 controls the conveyor belt 3 to continue working. The conveyor belt 3 will move the adjusted end caps to move closer to the electric grippers 8. During the adjustment of the end cap position angle, control cabinet 2 will control the first linear module 4 to work. The first linear module 4 will drive the moving plate 5, the servo motor 6, the first electric push rod 7 and the electric grippers 8 to move closer to the torsion spring loading plate (the torsion spring loading plate is located on the rear side of the mounting frame 1, not shown in the figure), so that the electric grippers 8 Located above the discharge port of the torsion spring feeding tray, the control cabinet 2 controls the first electric push rod 7 to drive the electric gripper 8 to move downwards, and uses the electric gripper 8 to clamp the torsion spring at the discharge port of the torsion spring feeding tray (the torsion spring clamping area is located between the two top blocks 27). After the torsion spring is clamped, the control cabinet 2 controls the first linear module 4 to drive the moving plate 5, servo motor 6, first electric push rod 7, electric gripper 8 and torsion spring to the installation position. When the control cabinet 2 detects through the first vision sensor 9 that the conveyor belt 3 has moved the end cover with the adjusted position angle to directly below the electric gripper 8, the control cabinet 2 will control the conveyor belt 3 to stop and control the first electric push rod 7 to work. The first electric push rod 7 drives the torsion spring to be installed in the groove on the surface of the end cover through the electric gripper 8, thus completing the assembly of the end cover and the torsion spring. When the rubber pad 11 of the gripping part 10 of the electric gripper 8 wears down due to long-term use, the control cabinet 2 will detect the wear of the rubber pad 11 through the first vision sensor 9. When the wear of the rubber pad 11 is detected to be severe, the control cabinet 2 will control the micro electric push rod 29 to work. The micro electric push rod 29 will drive the piston plate 30 to move closer to the rubber pad 11, so that the air pressure in the air pressure hole 31, which was originally in a negative pressure state, returns to normal, and releases the negative pressure state between the top block 27 and the rubber pad 11. At the same time, some of the gas inside the piston chamber 33 will enter the air pressure chamber 28 through the air pressure channel 37, so that the air pressure on one side of the piston block 34 will decrease. Under the action of the air pressure difference, the piston block 34 will drive the extrusion plate 36 away from the rubber pad 11 through the moving pin 35 (in the initial state, the extrusion plate 36 and the semi-circular cover are used). 32 can protect other intact areas of the rubber pad 11, delay aging, and prevent dust adhesion. Then, the control cabinet 2 controls the micro motor 261 to drive the rubber pad 11 to rotate at a set angle, so that other intact areas of the rubber pad 11 move to the surface of the top block 27. Then, the control cabinet 2 controls the micro electric push rod 29 to work in reverse, so that the space of the air pressure hole 31 increases and the air pressure decreases. The air pressure hole 31 is used to re-adsorb the rubber pad 11. After the negative pressure value inside the air pressure hole 31 exceeds the set threshold (-0.5 standard atmospheres), the external gas will enter the air pressure chamber 28 and the air pressure hole 31 through the pressure pipe 38 and the pressure relief valve 39. Similarly, after the piston plate 30 returns to its original position, the piston block 34 will drive the extrusion plate 36 to return to its original position through the moving pin 35, and continue to protect the intact areas of the rubber pad 11. After the electric gripper 8 clamps the torsion spring, the control cabinet 2 detects dust or other impurities on the surface of the torsion spring through the first vision sensor 9. The control cabinet 2 then controls the servo motor 6 to operate. The servo motor 6 drives the first electric push rod 7 to rotate 180 degrees and controls the first linear module 4 to operate. The first linear module 4 moves the first electric push rod 7, the electric gripper 8, and the torsion spring above the cleaning cylinder 21. Then, the control cabinet 2 controls the first electric push rod 7 to move the electric gripper 8 and the torsion spring downwards into the cleaning cylinder 21. Then, the control cabinet 2... The cleaning pump 192 is controlled to operate. The cleaning pump 192 delivers gas to the exhaust chamber 24 through the exhaust pipe 20 and discharges it through the upper air hole. The high-speed airflow cleans the impurities attached to the surface of the torsion spring. The cleaning pump 192 also extracts the gas inside the collection box 191. Under the action of negative pressure, the cleaned dust will enter the suction chamber 23 through the lower air hole along with the gas, and enter the collection box 191 through the suction pipe 25 for storage. This prevents the dust on the surface of the torsion spring from entering other components and affecting their performance.
