The system comprises a lifting module 32 at the moving end, a flipping module 33 installed at the lifting end of the lifting module 32, and a gripper holding module 34 installed at the flipping end of the flipping module 33. The forward and backward moving module 31 cooperates with the lifting module 32 to drive the gripper holding module 34 to the desired position. The gripper holding module 34 is used to hold the upper cover 51 or the assembled fixture 5. The flipping module 33 is used to flip the assembled fixture 5 90 degrees so that the bottom side of the fixture 5 faces the positioning mechanism 4 or the tray. The positioning mechanism 4 is used to position the fixture 5. Specifically, the tray is provided with a lower cover fixing position and an upper cover rotating position. The product is pre-fixed inside the lower cover of the fixture. Through this flipping and positioning mechanism, the upper cover is first installed on the lower cover, then the whole system is flipped to the positioning mechanism for positioning and locking, and then the side of the product is installed by the robot arm.

[0025] Please refer to the following: Figure 3 As shown, the forward and backward moving module 31 includes two bases 311 located on the left and right sides of the conveying channel 1, respectively. A forward and backward moving plate 312 is mounted on each base 311 via a forward and backward moving slide rail slider assembly 314. Each base 311 also has a forward and backward moving cylinder 313 for driving the forward and backward moving plate. The two forward and backward moving plates 312 serve as the moving ends of the forward and backward moving module 31. Specifically, the forward and backward moving cylinder has a cylinder diameter of 40mm, a stroke adjustment range of 100-300mm, and a maximum output force of 800N. The cylinder's extension and retraction are controlled by a control system, driving the forward and backward moving plate to move forward and backward along the forward and backward moving slide rail slider assembly. The forward and backward moving slide rail slider assembly uses a precision linear guide rail with a positioning accuracy of ±0.02mm. The forward and backward moving platform can perform translational strokes between the upper cover, lower cover, and positioning plate.

[0026] Please refer to the following: Figure 3 and Figure 4As shown, the lifting module 32 includes two uprights 321, each corresponding to one of the two front and rear movable plates 312. Each upright 321 has a lifting plate 322 mounted on it via a lifting slide rail slider assembly 324. Each upright 321 also has a lifting cylinder 323 for driving the lifting plate 322 to move up and down. The two lifting plates 322 serve as the lifting ends of the lifting module 32. Specifically, the lifting cylinder has a diameter of 32mm, a stroke adjustment range of 50-150mm, and a maximum output force of 500N. The cylinder's extension and retraction are controlled by a control system, driving the lifting plate to move up and down along the lifting slide rail slider assembly. The lifting slide rail slider assembly uses a precision linear guide rail with a positioning accuracy of ±0.02mm, ensuring smooth movement of the lifting platform and preventing offset when gripping the top cover.

[0027] Please refer to the following: Figure 4 As shown, the flipping module 33 includes a left-right flipping shaft 331; the left and right ends of the flipping shaft 331 are rotatably mounted to the corresponding uprights 321; a flipping seat 332 is fixed on the flipping shaft 331; a flipping gear 333 is also fixed near the left or right end of the flipping shaft 331; the flipping module 33 also includes a rack 334 meshing with the flipping gear 333, the rack 334 is mounted on the uprights 321 on the corresponding side through a rack moving mechanism, the rack 334 is used to move back and forth under the drive of the rack moving mechanism, driving the meshed flipping gear 333 to rotate, thereby driving the flipping shaft 331 and the flipping seat 332 to rotate; the flipping seat 332 serves as the flipping end of the flipping module 33. The rack and pinion moving mechanism includes a rack mounting base 335 fixed to the upright 321; a rack moving plate 336 is mounted on the rack mounting base 335 via a rack moving slide rail slider assembly 338; a rack moving cylinder 337 for driving the rack moving plate 336 to move back and forth is also mounted on the rack mounting base 335; the rack is fixedly mounted on the rack moving plate 336. Specifically, an angle encoder is installed on the flip shaft to detect the flip angle in real time and feed it back to the control system, realizing closed-loop control of the flip angle.

[0028] Please refer to the following: Figure 3 As shown, the gripper holding module 34 includes two grippers 341 distributed left and right, and a gripper cylinder 342 fixedly installed on the flipping end of the flipping module 33 for driving the two grippers to move towards or away from each other. Specifically, the grippers are made of polyurethane material with anti-slip texture on the surface. A pressure sensor is installed on the inner side of the grippers, and the gripping pressure can be set to 50-200N to provide real-time feedback on the gripping status, preventing damage to the top cover due to excessive pressure or detachment of the top cover due to insufficient pressure.

[0029] Please refer to the following: Figure 5As shown, the positioning mechanism 4 includes a gantry frame 41 located behind the flipping mechanism 3 and spanning above the conveying channel 1; a positioning plate 42 is fixed to the front side of the gantry frame 41; a plurality of positioning pins 421 corresponding to the fixture are provided on the front side of the positioning plate 42; the positioning mechanism 4 also includes a limiting mechanism 43 disposed at the top of the gantry frame 41. Specifically, there are two limiting mechanisms distributed left and right, and each limiting mechanism includes a limiting cylinder and a limiting block; when the fixture is fixed to the positioning plate 42, the limiting cylinder drives the limiting block to press against both sides of the top of the fixture, restricting its movement in the front, back, left and right directions.

[0030] This embodiment describes a flipping and positioning mechanism for automatic assembly of fixtures and product installation. The workflow is as follows: A tray carrying the lower cover (with the product already fixed) and upper cover of the fixture is conveyed to the flipping station via a conveyor system, where it is precisely blocked by a blocking mechanism (not shown in the figure). The forward and backward movement module and the lifting module of the flipping mechanism drive the gripper of the gripper module to the upper cover of the tray. The lifting module then moves the gripper downwards, and the gripper cylinder actuates to grip the upper cover of the fixture. The forward and backward movement module and the lifting module move the upper cover of the fixture to the lower cover's position. The lifting module then moves the gripper downwards, and the upper and lower covers are initially engaged and installed using their built-in locking pins. After assembly, the gripper cylinder actuates again to clamp both sides of the assembled fixture. The lifting module actuates to raise the assembled fixture to a set height. The rack and pinion movement cylinder actuates, driving the rack to rotate, thereby rotating the flipping gear. The rotating shaft, rotating seat, and gripper clamping module rotate 90 degrees, so that the bottom surface of the assembled fixture faces the positioning mechanism. The forward and backward moving module moves, pushing the assembled fixture towards the positioning mechanism. Through the positioning pin and the positioning hole of the fixture, the assembled fixture is positioned by the positioning mechanism. The limiting mechanism moves, limiting the fixture in the front, back, left, and right directions. At this point, the fixture is positioned, and the robot can pick up the material from the feeding point and accurately install the product onto the side of the fixture. After assembly, the limiting mechanism moves, releasing the fixture. The forward and backward moving module moves the fixture forward to the set position. The rack and pinion moving cylinder moves, causing the fixture to rotate 90 degrees, so that the bottom surface of the fixture faces the tray. The lifting module moves, placing the fixture into the lower cover fixing position of the tray. The gripper cylinder moves, releasing the fixture. The lifting module and the forward and backward moving module move, causing the gripper to return to the initial position. The conveyor channel starts, transporting the complete fixture with the assembled product to the next station.

[0031] This embodiment presents a flipping and positioning mechanism for automatic jig assembly and product installation. It integrates multiple processes such as jig assembly, flipping, positioning, and product installation into a compact system, which significantly shortens the production cycle, reduces material turnover, and improves production efficiency. The positioning mechanism performs pin hole positioning, and the limiting mechanism performs limiting, providing a reliable benchmark for product installation and ensuring extremely high precision and consistency of product installation.

[0032] The above embodiments should not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent conversion fall within the protection scope of the present invention.
