Description

Technical Field

[0002] With the accelerating pace of industrialization, many manufacturers have achieved automated production lines by deeply integrating artificial intelligence with edge computing, effectively improving production efficiency and achieving the goal of rapid production. However, when handling flexible materials, purely automated production models struggle to achieve ideal results. In existing technologies, automated equipment for flexible material pre-assembly typically relies on visual guidance from cameras and robots to complete material removal and product placement operations. However, this type of automated equipment has significant drawbacks, including high costs, complex internal structures, and high ongoing maintenance costs. Furthermore, due to the soft and easily deformable nature of flexible materials, automated equipment often struggles to precisely control the placement of flexible materials, resulting in a placement that fails to meet the production requirements of subsequent processes. This necessitates a series of subsequent adjustments, severely impacting the smoothness and efficiency of production and resulting in suboptimal fully automated pre-assembly of flexible materials.

[0038] Please refer to Figures 1 to 4 , a preloading and positioning automatic opening mechanism, including a base plate 1, a positioning component, a reset component, a sensor component 7, a rotating shaft 9, a manual pressing plate 10, a locking component, and a cylinder 19;

[0039] The positioning component and the locking component are arranged on the base plate 1; both ends of the rotating shaft 9 penetrate through the fixing plates on the base plate 1;

[0040] The reset assembly includes a tension spring 6 and a rotating wheel platform 8, the rotating wheel platform 8 is fixedly connected to the rotating shaft 9, and the two ends of the tension spring 6 are respectively connected to the base plate 1 and the rotating wheel platform 8; the manual pressure plate 10 is fixedly connected to the rotating shaft 9; the locking assembly includes a pair of oppositely arranged locking blocks 23; the locking blocks 23 are slidably connected to the base plate 1 through a sliding assembly, and a detection plate 12 is fixedly connected to the locking blocks 23, a pair of oppositely arranged locking blocks 23 are cooperated and connected with the lock column 11 of the manual pressure plate 10, and the output end of the cylinder 19 is connected to the locking block 23; the sensor assembly 7 is arranged on one side of the base plate 1 and corresponds to the position of the detection plate 12. The sliding assembly includes a spring 13, a limit plate 14, a slide rail 15, a second slider 21 and a guide post 20; the bottom of the locking block 23 is fixedly connected to the second slider 21, and the second slider 21 is connected to the slide rail 15 provided on the base plate 1. The limit plates 14 are provided in pairs and correspond to the positions of the two locking blocks 23. The lock block 23 is provided with a guide post 20 on the side close to the limit plate 14. The guide post 20 is covered with a spring 13, and the limit plate 14 is provided with a hole that cooperates with the guide post 20. The pre-pressed positioning automatic opening mechanism also includes a clamping plate 16, an L-shaped connecting plate 17 and a first slider 18; a strip hole is provided on the base plate 1, one end of the clamping plate 16 is fixedly connected to the locking block 23, and the other end of the clamping plate 16 is connected to one end of the L-shaped connecting plate 17 that extends through the strip hole to the lower surface of the base plate 1, and the other end of the L-shaped connecting plate 17 is fixedly connected to the first slider 18, which is connected to the output end of the cylinder 19.

[0041] The positioning assembly includes a first positioning block 2, a second positioning block 3, a third positioning block 4 and a positioning column 22; the first positioning block 2, the second positioning block 3, the third positioning block 4 and the positioning column 22 are all provided with limiting protrusions, and the specific structure of the manual pressing plate 10 and the positioning assembly needs to be adjusted and set according to the specific flexible material.

[0042] The sensor assembly 7 includes a fixed base, a longitudinal rotating column, an adapter block, a transverse rotating column and a sensor body; one end of the longitudinal rotating column is fixedly connected to the fixed base, the other end of the longitudinal rotating column is rotatably connected to the longitudinal through hole of the adapter block, one end of the transverse rotating column is rotatably connected to the transverse through hole of the adapter block, the other end of the transverse rotating column is fixedly connected to the sensor fixing plate, and the sensor fixing plate is fixedly connected to the sensor body. Through the cooperation between the longitudinal rotating column, the adapter block and the transverse rotating column, the position of the sensor body can be adjusted in both the transverse and longitudinal directions to prevent the sensor body from failing to correspond to the position of the detection plate 12.

[0043] The reset component further includes a tension spring mounting plate 5 which is fixedly connected to the substrate 1, and the tension spring 6 is detachably connected to the tension spring mounting plate 5. A protective shell for the reset component is provided on the outer surface of the reset component to prevent the tension spring 6 from being exposed to the outside for a long time, which may cause tiny particles, moisture and other substances to adhere to the surface of the tension spring 6, resulting in a decrease in the elasticity of the tension spring 6, easy fatigue damage and corrosion risk.

[0044] A plurality of mounting posts are evenly distributed on the rotary wheel table 8, and the tension spring 6 is detachably connected to any one of the mounting posts.

[0045] The working ends of the lock block 23 and the lock post 11 are both inclined surfaces. When the lock post 11 flips and contacts the lock block 23, the two lock blocks 23 can be quickly opened through the contact of the two inclined surfaces. After the lock post 11 flips in place, the lock block 23 automatically resets to lock the lock post 11 to prevent the lock post 11 from automatically rotating back.

[0046] In actual use, the paired lock blocks 23 are initially in a closed state. The flexible material is pre-positioned through the positioning component. Then, the operator presses the manual pressing plate 10, which drives the rotation of the rotating shaft 9 and the stretching of the tension spring 6. The lock post 11 contacts and squeezes the lock block 23, pushing the lock block 23 to move to both sides until the lock post 11 is fully inserted in place. The lock block 23 automatically returns to its position to lock the lock post 11. At this time, the manual pressing plate 10 pre-presses the flexible material in place for fastening. Then, other process flows are carried out. After other process flows are completed, through the displacement mechanism such as the slideway provided at the bottom of the substrate 1, the whole mechanism is automatically moved to the pick-up position of the operator. The air cylinder 19 automatically opens, driving the L-shaped connecting plate 17, the clamping plate 16 and the lock block 23 to move outward. The tension spring 6 automatically retracts, driving the rotating shaft 9, the rotary wheel table 8 and the manual pressing plate to return to their positions. Then, the lock block 23 resets; the sensor body detects the position change of the detection plate 12 on the lock block 23 in real time to monitor whether the position of the lock block 23 is in place, ensuring safety for other actions and production, and then a reciprocating process is carried out; through this mechanism, manual auxiliary pre-installation of the flexible material can be carried out, and the flexible material can be accurately placed in position. The whole process is convenient to operate and highly feasible. Compared with cameras and robot vision guidance, it has higher stability, and will not affect the subsequent processes due to inaccurate placement positions. Moreover, the overall structure of this mechanism is simple, with low cost and low maintenance cost.

[0047] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or alterations derived therefrom still fall within the protection scope of the creation of the present utility model.
